(2012). An Empirical Study on Brand Equity in Malaysian Fast Food
CHAPTER 1 INTRODUCTION 1.1 Introduction Fast food brand is defined as those restaurants that provide expedited food service, established standard operating procedure, offered Western pattern diet, and had franchises in multiple states or nationwide (Ashkanasy & Nicholson, 2003; Block, Scribner & DeSalvo, 2004; Burdette & Whitaker, 2004; Slattery, Boucher, Caan, Potter & Ma, 1998). According to Kim and Kim (2004), brand name is the key assets for fast food companies. If manages appropriately, the positive brand name will drive to competitive advantage (Szymanski, Bharadwaj & Varadarajan, 1993), price premium (Keller, 1993), low switching to better competitors (Narayandas, 1996), and recommendation to others (Russell-Bennett, McColl-Kennedy & Coote, 2007). Brand equity existed when a consumer had preference in choosing a focal branded product, but not an unknown brand that had the identical level of product features (Kamakura & Russell, 1993). The concept of brand equity consists of different dimensions such as perceived quality, brand awareness, brand image, brand loyalty, and other proprietary brand assets (Aaker, 1996). Up-to-date, the existing literature on brand equity model within the fast food industry was still sparse (Tan, Hishamuddin & Devinaga, 2011). Besides, the identification of causal effects among brand equity dimensions was not clearly extended by the implication of marketing theory (Gil, Andrés & Salinas, 2007; Konecnik and Gartner, 2007). Such limitations have caused ambiguity in managing and predicting the tangible and intangible characteristics of fast food brand (Kim and Kim, 2005). For these reasons, this study was conducted to fill in the limitations as mentioned. 1 1.2 Problems Background 1.2.1 Fast Food Industry in Global According to Datamonitor (2009), in year 2008, global fast food market had reached a value of RM479.57 billion, with growth rate of 6.6%. In term of transaction value, the volume reached 85.8 billion of transactions, counted as 3% growth rate. On the other hand, global fast food market were expected to reach a total revenue of RM620 billion, while transactions value were projected to have a volume of 94.7 billion, an increase of 29.3% and 10.4% from year 2008 to 2013 (Datamonitor, 2009). As a result, fast food was considered as an important industry due to its global trend (Oyewole, 2007; Van Zyl, Steyn & Marais, 2010). Out of numerous types of fast food segment, Quick Service Restaurant (QSR) ranked as the leading segment; this was because QSR accounted for 66.3% of the overall value in the global fast food market, and American brands dominated approximately 52.4% of the overall global fast food market (Datamonitor, 2009). 1.2.2 Fast Food Industry in Malaysia Hamisah (2007) declared that many U.S brand companies dominated the Malaysian fast food industry, for instance McDonalds, Burger King, Kentucky Fried Chicken, Kenny Rogers Roasters, A&W, Pizza Hut, Domino Pizza, Shakeys Pizza, T.G.I.F, Chilis and so on. Kentucky Fried Chicken (KFC) brand became the most flourishing fast food restaurant in Malaysia, this could be supported by KFC dominated the market share with 44% (Aseambankers, 2007) and successfully expanded more than 500 outlets in Malaysia (The Star, 2011). 2 According to Aseambankers (2007), KFC Malaysia was owned by KFC Holdings Bhd, a Malaysian public-listed company, which controlled over 60% of the fast food market in Malaysia, inclusive other brands such as Pizza Hut, Rasamas, and Ayamas. Figure 1.1 illustrated KFC, McDonald’s, and Pizza Hut were the leaders in the Malaysian fast food industry. Source: Aseambankers (2007) Figure 1.1: Estimated Market Share of Fast food Segment in Malaysia Hamid (2009) outlined that the government had been trying to provide support to the Malaysian fast food brand through government assistance programs, but it was still at an introductory stage. A number of Malaysian franchise systems had started expanding to other countries, such as Singapore, Indonesia, China, Dubai, India, and Bahrain. Hamid (2007) indicated that Marrybrown was present in over ten countries, with Middle East as its stronghold. Bernama (2009) reported that 1901 Hot Dogs, a Malaysian brand had enjoyed good response from overseas such as Singapore. Even though Malaysian brands received good evaluation form other countries, only a few of them were doing well, reason being lack of expertise in branding and marketing (Marshall Cavendish, 2009). Furthermore, the market share of fast food in Malaysia was subjugated by foreign brands (Aseambankers, 2007). 3 1.2.3 Issues Related to Brand Equity in Fast Food Restaurants Compared to other types and concepts of restaurant business, such as mid scale restaurant, upscale restaurant, and café, fast food restaurants had gathered greater interest in building a strong brand because of the products and services were not naturally differentiated (Tan et al., 2011). Furthermore, the channels of distribution were not unique. As a result, consumers relied on price setting and brand equity for the purpose of differentiating one brand from another (Aaker, 1996). William (2000) argued that managers could also depend on price manipulations when there was nonexistence of well-built brands. Siguaw, Mattila and Austin (1999) identified fast food players had treated price promotion as an important marketing activity, such practice had resulted in continual price wars that reduced revenue, earning per product sold and product quality. For instance, McDonald’s Weekday Breakfast Special and McValue Lunch, KFC Jom Jimat, Marrybrown Makan Enak, Makan Jimat, 1901 Hot Dogs 19th Lucky, and Domino’s Pizza Incredible Meal. However, MIDF Research (2010) stated that food and beverage manufacturers could not escape from high raw materials costs, for instance, Nestle, F&N, and fast-food firms were expected to face some costs pressure. They had to increase the selling price in order to mitigate the downsides. As a result, promotional strategies were not the best marketing solution in gaining fast food market share. Rao and Monroe (1989) advocated that brand name seemed to be positively associated with consumer product evaluations, perceptions of quality and purchase rates. Kim and Kim (2004) highlighted that brand name was the key assets for fast food companies. This could be supported by the positive brand name, such as recognizable brand identifiers would drive to competitive advantage (Szymanski et al., 1993). For this reason, Kotler, Bowen and Makens (2003) indicated that consumers would not have difficulty in recognizing the symbol of Thank Goodness It’s Friday (TG.I. Friday’s) and McDonald’s. 4 According to Keller (1993), branding could have great effect on the price premium of the product offered, especially in a market where the product was identical. It added value to a basic product or service, which prompted repeated purchase (Chiou & Droge, 2006), low switching to better competitors (Narayandas, 1996), and recommendation to others (Russell-Bennett et al., 2007). Consequently, brand equity facilitated the sustainability of business by increasing market share, which directly ensured the consistency of income stream and cash flow of the company (Aaker, 1996). Therefore, fast food restaurant had to focus on the effort to develop brand equity. The reason being given as brand equity had mitigated the focus on price promotion. However, to the question “Is it sufficient to adopt the original four dimensions of brand equity as proposed by Aaker (1991) in fast food study?” Such question remained unclear and lead to the potentiality of a research gap. Furthermore, most of brand equity studies were conducted in the United States, Europe, China and Korea (Gil et al., 2007; Kim & Kim, 2005; Tong & Hawley, 2009; Yoo, Donthu & Lee, 2000); the findings might not have been applicable to the market without empirical testing. The results from previous studies might not be similarly associated with consumers in other countries with different cultures and consumer behaviors (Chou, Chen, & Wang, 2012), such as multiracial consumers in Malaysia. Studies had indicated that consumers behave differently across countries and cultures, thus, different value system existed among consumers from different parts of the world (Corkindale & Lowe, 1998; Grunert & Scherhorn, 1990; McCracken, 1989; Tansuhaj, Gentry, John, Manzer & Cho, 1991). This could be further supported by some significant inconsistencies which existed in consumer responsiveness to different marketing efforts, even though there are some similarity of geographical and cultural between Malaysia, Taiwan, and Thailand (Huff & Alden, 1998). As a result, there was a need to develop a consumer-based brand equity model in the Malaysian context of fast food industry empirically. 5 1.2.4 Brand Familiarity as Additional Dimension Interestingly, most of the people knew fast food brands such as A&W, McDonald’s, KFC, and Pizza Hut since childhood. Consumers were more familiar with famous fast food brands as compared to well-known product brands such as MercedesBenz, BMW, Nike, Prada or Adidas (Tan et al., 2011). Referring to Mano and Davis (1990), the familiarity of fast food brand played an important role in product preference. The role of familiarity also appeared to be far greater for the situation where the consumer was looking for a simple rule for decision making (Batra & Ray, 1985), such as fast food. This could be explained by most of the Generation Y, who were born between years 1982 to 2003, recognized fast food brand (see Table 1.1) since childhood because they were frequently exposed to fast food advertisement during children programs. Schlosser (2002) expressed the flavors of childhood food which had left an indelible mark, and where adults often returned to them, without always knowing why. Table 1.1: Familiar Products of Fast Food Brands Fast Food Brand Products that Appeared from Our Mind Due to Familiarity McDonald’s Big MacTM, McChickenTM, Filet-O-FishTM, and Happy MealTM KFC Hot & Spicy Chicken, O.R. Chicken, Whipped Potato, and Zinger Burger Pizza Hut Super Supreme, Island Supreme, and Seafood Lasagna A&W Root Beer, Mozza Burger, and Coney Dog Study conducted by other researchers had also indicated that brand familiarity drove to positive attitude towards the brand, consumer confidence, and purchase intention (Laroche, Toffoli, Kim & Muller, 1996). It also served as an important platform in mitigating the possible unenthusiastic impact of a negative trial experience (Smith, 1993). Besides, Schlosser (2002) stated brand familiarity had transformed fast food to become “comfort food”, which served as a source of pleasure and reassurance. Thus, brand familiarity served as an additional dimension of consumer-based brand 6 equity in the context of fast food industry in Malaysia. The exclusion of brand familiarity was not sufficient to explain the effort in developing brand equity (Baker, Hutchinson, Moore & Nedungadi, 1986). 1.2.5 Brand Trust as Additional Dimension Beside brand familiarity, what was the other factor that contributed to the preference of fast food brand? There was a high consistency in the operation of fast food, for instance taste, portion, price, presentation, promotion, services, business hours, environment, and facilities. This was because fast food chains maintained standard operating procedures. For these reasons, the fast food meals that were bought from any outlets had high similarity. For instance, McDonald’s French Fries that was presented in Mid Valley Megamall, a Kuala Lumpur outlet was not different in term of taste and portion, as compared to McDonald’s French Fries which was purchased from Api-Api Centre outlet in Kota Kinabalu, Sabah. As a result, consumers relied on the capability and accountability of the brand instead of people involved in the restaurants (Keller, 1993). The reliability of the brand’s functions had led to the feeling of security held by the consumer when interacted with the brand (Johnson & Grayson, 2005). This statement was supported by Table 1.2 as extracted from the study of McDonald’s (2011), KFC (2011), and Pizza Hut (2011). 7 Table 1.2: Consistency of Business Operation and Performance of Fast Food Brands Items Descriptions Food preparation Food presentation Food category Standard operating procedure (SOP) Simple and clean Children, breakfast, dessert, set meal, beverage. Accurately charge and same price Fast and convenience Yes Breakfast, lunch, refillable Yes Available in every states 24 hours or according to standard hours Air-conditional, Wifi, music From time to time Food price Food served Halal Promotion Nutrition information Location Operating hour Environment Advertising Consistent across Different Branches Source: McDonald’s (2011), KFC (2011), and Pizza Hut (2011) Morgan and Hunt (1994, p. 23) stated that trust exists “when one party has confidence in an exchange partner’s reliability and integrity.” This could be further explained that the formation of trusted business relationships would be established when there is an understanding of exchanged partners in between the brand and consumer (Morgan & Hunt, 1994). In the context of fast food business, both parties would mutually benefit as trust is created with an exchange of environment in which the brands provided consistent services to its customers across different outlets, which indicated high reliability and integrity status of the brand itself, and results the brand is reliable and responsible for the interests and welfare of them at anywhere and at anytime, consequently such a situation could be explained as brand trust (DelgadoBallester & Munuera-Aleman, 2005). Therefore, brand trust serves as an important dimension of consumer-based brand equity in the context of fast food industry in Malaysia. The exclusion of brand trust was not sufficient to explain the efforts in creating brand equity. 8 1.2.6 Brief Literature Gaps in Brand Equity The effort of developing brand equity is a long-term program and requires the regularity of marketing efforts (Aaker, 1996). According to Kim and Kim (2005), there are four dimensions of brand equity in fast food industry, namely perceived quality, brand awareness, brand image, and brand loyalty. However, only brand awareness and perceived quality had significant effects on corporate performance (Kim & Kim, 2005). Tan et al. (2011) argued that the high numbers of brand equity dimensions, i.e. six as proposed in has gained research interest among academician and practitioners. For instance: “Are there any pre-determinate constructs among the brand equity dimensions?” “Are there any direct contribution of a) each dimensions b) certain dimensions to brand equity?” “What subsequent benefits could brand familiarity and brand trust contribute in the context of fast food industry?” Hence, there was a need to identify the causal relationships among dimensions of brand equity in the Malaysian context of fast food industry; this could serve as a platform in answering above stated research questions. The investigations of causal directions for brand equity dimensions were important because it helped to identify a clear direction for strategy planning. Aaker (1991) indicated that the dimensions of brand equity were intimately interrelated. However, Agarwal and Rao (1996) highlighted that the dimensions could have causal effects; in other words, there was potentiality of causal relationships among the dimensions of brand equity. Aaker (1991) suggested that brand loyalty could be influenced by the other dimensions of brand equity, such as perceived quality. This was supported by Gil et al. (2007), indicating that brand awareness/association had direct effect on brand loyalty, and only brand loyalty positively affected on brand equity. 9 Similarly, Yoo and Donthu (2001) noted that the dimensions of brand equity had sequential effects. This could be further explained, as perceived value was the antecedent of brand awareness and brand association, and both brand awareness and brand association had influenced on brand loyalty. Tong and Hawley (2009) empirically proved that only certain dimensions have causal effect on brand equity; they further explained that the existence of indirect effects, both brand association and brand loyalty served as mediating variables in explaining the relationships between brand equity and perceived quality or brand equity and brand awareness. In the apparel market, Tong (2006) argued that there were significant numbers of causal effects existed among the dimensions of brand equity, which highlighted the important of causal relationships. However, only few empirical research studies (Pike, Bianchi, Kerr & Patti, 2010; Boo, Busser & Baloglu, 2009; Rosa & Riquelme, 2008) focused on identifying the causal relationships among brand equity dimensions simultaneously, due to the complexity of research design and analysis. Most of the researchers purely indicated that the relationships between various variables and brand equity (Tong & Hawley, 2009; Norjaya, Mohd Nasser & Osman, 2007; Yoo, Donthu & Lee, 2000), brand resonance (Norzalita & Norjaya, 2010), or brand outcomes (Baldauf, Cravens & Binder, 2003; Henry, Catherine & Ada, 2010; Kim & Kim, 2005). Furthermore, there were no implication of cognitive-affectiveconative on Aaker’s (1991, 1996) or Keller’s (1993, 1998) brand equity model, which classified brand equity dimensions based on hierarchy of effects theory (Belch & Belch, 2009). 10 1.3 Problem Statements Previous studies found that perceived quality, brand awareness, brand image, and brand loyalty were dimensions of brand equity (Henry et al., 2010; Kim & Kim, 2005). However, the findings for brand equity dimensions were inconsistent across different industries and products (Boo et al. 2009; Pike et al., 2010; Xu & Andrew, 2009). Therefore, past studies had shown that brand equity dimensions had not assisted in anticipating the development of brand equity in Malaysian fast food industry. This was supported by brand familiarity as indicated by Schlosser (2002) and brand trust by Delgado-Ballester and Munuera-Aleman (2005). These dimensions might play important dimensions of brand equity in the context of fast food industry, but not for other type of products or industry. Thus, the summary of the problem statement is presented as below: “To what extent do the brand familiarity and brand trust served as additional dimensions of consumer-based brand equity in the Malaysian context of fast food industry” Although fast food industry had huge market size, increasing economy, and growth opportunities, Malaysian fast food brands lacked expertise in branding and marketing (Marshall Cavendish, 2009). Furthermore, despite the huge demand for U.S brands and purchasing power for foreign fast food brands which existed in Malaysia, only a few successful Malaysian fast food brands had survived (Hamid, 2009). According to Keller (1993), branding had a great effect on the price premium of product offered, especially in a market where the product is similar. Brand equity added value to a basic product or service, for instance repeat purchase (Chiou & Droge, 2006), low switching to better competitors (Narayandas, 1996), and recommendation to others (Russell-Bennett et al., 2007). Consequently, brand equity facilitated the sustainability of business by increasing the market share, which directly ensured the consistency of income stream and cash flow of the fast food company (Aaker, 1996). 11 For these reasons, it is important to know how to develop a brand equity model in the Malaysian fast food industry. Nevertheless, only few empirical research studies (Pike, Bianchi, Kerr & Patti, 2010; Boo, Busser & Baloglu, 2009; Rosa & Riquelme, 2008) had focused on identifying the causal relationships among brand equity dimensions simultaneously, due to the complexity of research design and analysis. Furthermore, there was no classification of brand equity dimensions that was based on hierarchy of effects theory, which was a general guideline for the development for most of the available marketing models (Belch & Belch, 2009). Subsequently, the summary of the problem statement is illustrated as follow: “To what extent that the consumer-based brand equity could be developed in the Malaysian context of fast food industry” 1.4 Research Questions Four research questions were derived from the problem background and problem statement such as: 1) Does brand familiarity serve as an additional dimension of consumer-based brand equity in the Malaysian context of fast food industry? 2) Does brand trust serve as an additional dimension of consumer-based brand equity in the Malaysian context of fast food industry? 3) What are the causal relationships among dimensions of consumer-based brand equity in the Malaysian context of fast food industry? 4) How do we develop consumer-based brand equity model in the Malaysian context of fast food industry? 12 1.5 Research Objectives Specifically, this study had derived four research objectives, which were informed and inspired from the research questions as illustrated above. The following four research objectives reflect to the current research gaps of consumer-based brand equity in the Malaysian context of fast food industry. The detail of the research objectives were discussed as below. Research objective 1: To examine brand familiarity as the additional dimension of consumer-based brand equity in the Malaysian context of fast food industry. Thus, this study firstly identified the significance level of the hypotheses that related to brand familiarity. Secondly, this study had focused on the squared multiple correlations. Finally, the study had re-tested the model without the inclusion of brand familiarity. Research objective 2: To examine brand trust as the additional dimension of consumer-based brand equity in the Malaysian context of fast food industry. Basically, the investigations of brand trust were similar to brand familiarity as mentioned above. Research objective 3: To investigate the causal relationships among dimensions of consumer-based brand equity in the Malaysian context of fast food industry. This study had included brand familiarity and brand trust in the proposed framework. A comprehensive set of causal relationships among the dimensions of consumer-based brand equity had been tested in a structural model simultaneously. Subsequently, the sequential order among the brand equity dimensions, and the significant compound paths could be identified. 13 Research objective 4: To develop consumer-based brand equity model in the Malaysian context of fast food industry. Firstly, the proposed model had to conciliate all the reliability and validity assessments for measurement and structural model, before it could be claimed as a statistically valid model. Next, this study compared the proposed model with the existing theories, such as Aaker’s (1991) and Gil et al.’s (2007) model. The main purpose of this study was to identify whether there were any significant different of results, such as the causal effects and squared multiple correlations. Lastly, the proposed model had to be supported by the interpretation of general marketing literatures. 1.6 Justification of Research This study highlights three important contributions in brand equity. Firstly, this study is aimed to extend consumer-based brand equity model by decomposing brand familiarity and brand trust. These could be supported by the role of familiarity appeared to be far greater for the situation where the consumer was looking for a simple rule for decision making (Batra & Ray, 1985), such as fast food. On the other hand, DelgadoBallester and Munuera-Aleman (2005) identified that brand trust could be resulted from the high reliability and integrity status of the fast food brand itself. As a result, the exclusion of brand familiarity and brand trust were not sufficient to explain the efforts to develop brand equity, especially in the context of fast food industry. Secondly, this study was attempted to fill the gap in research by demonstrating a comprehensive set of casual relationships among brand equity dimensions. Up-todate, only few empirical research studies (Pike et al., 2010; Boo et al., 2009; Rosa & Riquelme, 2008) focused on investigating the causal relationships among brand equity dimensions. Furthermore, the identification of causal effects was not clearly extended by the implication of hierarchy of effect theory (Gil et al., 2007; Konecnik & Gartner, 2007). For instance, there were still no consensus about the sequence or causality between cognition and affect (Oliver, 1997; Franzen & Bouwman, 2001). In additional 14 to that, Barry and Howard (1990) stated that there were significant disagreement regarding the order of the three stages, the model could be presented in cognitionaffect-conation, cognition-conation-affect, affect-cognition-conation, affect-conationcognition, conation-cognition-affect, or conation-affect-cognition. Subsequently, this might lead to the confusion for the justification of causal effects. This purposeful research idea, served as an important research in contributing as a general guideline for the establishment of causal effects among the dimensions of consumer-based brand equity. Thirdly, this study had provided a better conceptualization for the consumerbased brand equity dimensions, which have led to better measurement of the variables. Several researchers have explored brand equity measurement based on customers’ perspectives (Park & Srinivasan, 1994; Washburn & Plank, 2002; Yoo et al., 2000). However, there was lack of research focused on how to characterize the consumer’s response towards the brand. Subsequently, some research studies indicated that brand measurement model had to be free from the establishment marketing literature (Boo et al., 2009; Delgado-Ballester & Munuera-Aleman, 2001). This study had incorporated cognitive, affective, and conative components into categorization of brand equity dimensions, which were extremely similar to the interpretation given by some scholars to the term brand equity (Grimm, 2005). Consequently, it reduced the ambiguous for the conceptualization of consumer-based brand equity dimensions. As a conclusion, this study enhanced the conceptual framework of consumerbased brand equity. It empirically examined the applicability of the existing consumerbased brand equity models by integrating additional dimensions and provided a more practical framework, which served as a platform for future research in the hospitality industry. 15 According to Marshall Cavendish (2009), Malaysian fast food brands lacked expertise in branding and marketing. Importantly, they did not equip themselves with the fundamental idea in designing and mapping branding tools. Practically, this study had identified four distinctive steps of brand equity creation in the Malaysian fast food industry, which have produced a source for brand management in improving organizational decision making. Consequently, the findings had provided a good guideline for fast food managers to allocate their resources accordingly, which included the arrangement of priority, financial resources, and human capital. It also helped them to develop clear directions in positioning their brands that was based on consumer response (Mohd Rizaimy, Suhardi & Shamsul, 2011). Most of the government assistance programmes were based on traditional marketing, such as packaging (Small and Medium Enterprise Corporation Malaysia [SME Corp. Malaysia], 2011b), business management (Ministry of International Trade and Industry [MITI], 2011), financial assistance (Perbadanan Nasional Berhad [PNS], 2011), and collaboration with external parties (SME Corp. Malaysia, 2011a; MDTCC, 2011a). There was lack of training programme that focused on the development of fundamental knowledge among local entrepreneurs; reason being that most of the branding trainings were focused on packaging (SME Corp. Malaysia, 2011a). Local entrepreneurs had to equip themselves with the ideology of brand equity creation. Consequently, they would response to the market changes independently and not have the mindset of depending on the supported facilities from the government. That is, they became more proactive than reactive and had a better direction for the planning of branding strategy. 16 The findings for this research will be useful for the development for branding activities among local entrepreneurs. It also allowed our university to collaborate with the Ministry of Domestic Trade, Co-operative and Consumerism (KPDNKK) and Ministry of International Trade and Industry (MITI) in setting customized branding strategy. The ministries could apply the findings as fundamental in formulating government assistance programs for local entrepreneurs, especially in training programs (SME Corp. Malaysia, 2011a). As a conclusion, this study had provided a solution for assistance programmes, highlighted alternative approach for the growth of Malaysian brand in fast food industry, which was based on the development of fundamental knowledge among local entrepreneurs 1.7 Scope of Study This study had focused on Malaysian fast food industry, particularly for fast food chains that provided expedited food service, established standard operating procedure, offered Western pattern diet, and have franchises nationwide or in multiple states (Ashkanasy & Nicholson, 2003; Block et al., 2004; Burdette & Whitaker, 2004; Slattery et al., 1998). The stimulated brands were McDonald’s, Kentucky Fried Chicken, Pizza Hut, Marrybrown, and 1901 Hot Dogs as they controlled approximately 80% fast food market share in Malaysia (Aseambankers, 2007). A total of 600 self-administrated questionnaires were distributed among fast food consumers from Klang Valley. Klang Valley was selected as it drew out with heterogeneous sample that constituted people from all ethnic groups and various demographic characteristics (Norzalita & Norjaya, 2010). For these reason, Klang Valley are widely selected for Malaysian research (Chan, 2009; Chok, 2008; Hee, 2009; Hishamuddin, 2007; Norjaya et al., 2007; Norzalita & Norjaya, 2010; Ooi, 2009; Siti Safira, 2008; Yap, 2009). 17 1.8 Definition of Terms The following definitions would provide a better understanding of the concepts for this study: Attitudinal brand loyalty The indication of consumer’s psychological commitment towards the brand (Chaudhuri & Holbrook, 2001). Brand The identity of a specific product, service, or business and it could take many forms, including a name, sign, symbol, color combination or slogan (Aaker, 1991). Brand awareness The potentiality of consumer to identify a particular brand from his or her memory when encountering a selection process or decision making progress from the product category (Aaker, 1991; Heding, Knudtzen & Bjerre, 2009). Brand equity Brand equity existed when a consumer had preference to choose a focal branded product, but not an unbranded product that had the same level of product features (Kamakura & Russell, 1993). Brand familiarity The number of brand-related experience that a consumer had built up (Alba & Hutchinson, 1987). 18 Brand knowledge The brand served as a node of an associative network memory which linked various types of associations, comprised of brand awareness and brand image (Keller, 1998). Brand image The overall consumer perception or impression towards a brand due to its superiority, uniqueness, strength, favorability, and different kinds of association (Keller, 2003). Brand trust The positive emotional feeling and affective reactions that results from the trusted brand (Chaudhuri & Holbrook, 2001; Corritore, Kracher & Wiedenbeck, 2003; Riegelsberger, Sasse & McCarthy, 2005). Consumer-based brand equity The brand commitment that resulted from consumer’s perception of overall superiority (cognitive to conative stage) of a particular product or service category carrying that brand name (Belch & Belch, 2009; Heding et al., 2009). Fast food brand Fast food corporation that provided expedited food service, established standard operating procedure, offered Western pattern diet, and had franchises in multiple states or nationwide (Ashkanasy & Nicholson, 2003; Block et al., 2004; Burdette & Whitaker, 2004; Slattery et al., 1998). Perceived quality The overall customers’ cognitive response on the superiority of service quality as offered by companies and employee (Chiou, Droge & Hanvanich, 2002). 19 1.9 Organization of the Thesis Chapter 1: Introduction This chapter introduced the study by identifying the key meaning and variables. Later it outlined problem background, which served as an important platform in understanding current research gap. Next, the research questions and research objectives were identified from the problem statement. Subsequently, the chapter indicated the justification and scope of the study. Chapter 2: Literature Review This chapter reviewed theoretical development of consumer-based brand equity for this study. Next, it reviewed the relevant literature to provide critical comments for the dimensions of consumer-based brand equity, such as perceived quality, brand awareness, brand familiarity, brand image, brand trust and attitudinal brand loyalty. Chapter 3: Research Methodology This chapter justified the development of research framework and hypotheses. Next, it highlighted detail of questionnaire developments. The sample of the study, stimulated brands, and data collection procedure were explained in the following sections. Later, it was followed by the detail and result of pilot study. Finally, the chapter identified the research design for the main study, which comprised sample size and data selection, data collection procedures, and method of data analysis. Chapter 4: Data Analysis This chapter is to present the results from the main study. Basically, there are four distinctive parts of this chapter. Firstly, the sample descriptions was presented, which included the respondents’ background and descriptive analysis of the variables. Next, a series of tests were conducted in order to satisfy the confirmatory factor analysis, before the measurement model could be transferred to structural model. The chapter was followed by the results of hypotheses. Lastly, model re-specification was carried out to compare the proposed model with the existing theories. 20 Chapter 5: Discussions on Findings This chapter discussed and interpreted the result of hypotheses. Each of the hypotheses was clearly identified, and was supported by the previous literatures. Subsequently, the chapter overviewed general findings of this study, which served as a vital platform in responding to the research objectives, such as the importance of brand familiarity and brand trust, and the identification of causal relationships. Chapter 6: Conclusion and Recommendations This chapter firstly discussed on the achievement of research objectives. Next, the study justified the contribution of this study, in term of both academicians’ and practitioners’ perspective. Lastly, the recommendation for future study. 21 chapter covered the limitation and CHAPTER 2 LITERATURE REVIEW 2.1 Introduction Basically, this Chapter is divided into three important categories. First, it comprises of Section 2.2 and 2.3, which clearly identify the different types of brand equity conceptualization in current marketing literature. The identification of conceptualization was important because it serves as a good understanding of conceptual framework for this study. Therefore, Section 2.3 indicates the summary of the findings on brand equity from year 1991 to 2011. Section 2.4 discusses the four widely used brand equity theory, by Aaker (1991), Keller (1993), Lasser el at. (1995), and Gil et al. (2007). Next, the development of the brand equity concept for fast food context is discussed, such as the replacement of brand association with brand image, the inclusion of brand familiarity and brand trust, and brief justification for the selection of attitudinal brand loyalty. The main purpose was to ensure that the conceptual framework of this study was supported by fundamental theory. Section 2.5 to 2.10 reviews all the constructs that was used in this study, namely perceived quality, brand awareness, brand familiarity, brand image, brand trust and attitudinal brand loyalty. All of the discussions were based on previous researchers’ definitions, association of theoretical and empirical findings. 22 2.2 Brand Equity In general, brand equity was the incremental utility and added value to a product by its brand name, for instance Mercedes-Benz, BMW, Nike, Adidas, Coke, Pepsi, Kodak, Gucci, Louis Vuitton, Levi’s, McDonald’s and Starbucks (Tan et al.). There have been many definitions given, for instance incremental utility (Kamakura & Russell, 1993); unique value added from the brand (Farquhar et al., 1991); superiority and brand choice (Agarwal & Rao, 1996); and difference between overall brand first choice (Park & Srinivasan, 1994). According to Bello and Holbrook (1995), brand equity was the tremendous value inherent in a famous brand name; it referred to the attractiveness of the brand name associated to the products or services. This was explained by the willingness of consumers to purchase the similar quality of products or services with higher price or price premium, and this was explained as the effect of deep-rooted impression and positive image of the brand in the minds of consumers (Bello & Holbrook, 1995). Some researchers indicated that brand equity contributed in customer value (Cobb-Walgren, Beal & Donthu, 1995; Keller, 1993). For example, it led to greater consumers’ confidence, customer satisfaction, and information processing towards the brands. Adler and Freedman (1990) further suggested that brand equity provided shortterm protection from competition (based on consumer loyalty and switching costs), and served as basic to protect its market share from any new idea of competitors. 23 According to Lane and Jacobson (1995), brand equity created intangible assets for company, for instance it increases credibility and reputation of company, and these intangible assets were considered much superior than tangible assets. This could be explained that an established brand name would serve as an important platform for the product extension (Aaker & Biel, 1993). Moreover, researchers stated that brand equity had positive impact on company’s profitability and sustainable cash flow (Srivastava & Shocker, 1991), willingness of consumer to pay premium prices (Keller, 1993), sustainable competitive advantage (Szymanski et al., 1993), growth and stability of stock prices (Lane & Jacobson, 1995; Simon & Sullivan, 1993), firm performance (Kim & Kim, 2005), and successfulness of marketing efforts (Styles & Ambler, 1995). Overall, the enhancement of brand equity led to higher purchase intention, prices premium, lower probability of price elasticity, greater competitive advantages, higher market value, and business profitability and sustainability (Keller, 2003). In contrast, weaker brand equity had a negative effect in the long term (Ailloni-Charas, 1991). This could be supported by consumers were most likely to switch to other brands in the marketplace if there was a lack of brand management. For many years, brand equity had been a topic of interest in consumer goods market, particularly the fast-moving consumer goods. However, there were different findings could be found in brand equity study, especially for components such as brand association or brand image. This could be evidenced in retailer brand equity; retailer association was proved to be varied across store category (Grace & O’Cass, 2005; Sinha & Uniyal, 2004). 24 Additionally, similar marketing instrument acted differently across consumer goods market and service market. For instance, customer service was considered as part of the elements of perceived quality, but it was treated as a marketing element in consumer goods market (Bamert & Wehrli, 2005). Besides, there were different perspectives on the conceptualization of brand equity. In the next section, the selection of brand equity concepts would be discussed in detail. 2.2.1 Two Different Perspectives in Brand Equity Conceptualization There were many measurements of brand equity due to the different concepts created and, as a result, there is a wide spectrum of different perspectives on how brand equity ought to be conceptualized and managed (Aaker, 1991; Keller, 1993; Lassar et al., 1993). Brand equity subsumed to brand strength and brand value (Srivastava & Shocker, 1991). According to Keller (1998), brand strength was referred to the set of associations and behaviors on the part of a brand’s customers, channel members, and parent corporation that permits the brand to enjoy sustainable and differentiated competitive advantages (consumer-based perspective). On the other hand, brand value was defined as the financial result (financial perspective) that was derived from the skillful and strategic management of talent in leveraging brand strength, which served its purpose to support the superiority of current and future profits; at the same vein it lowered the risk of the corporation (Srivastava & Shocker, 1991). The main aim of this study was to develop a consumer-based brand equity model in the Malaysian context of fast food industry, which focused on understanding the constitution of associations held by consumers towards the fast food brands (Yoo et al., 2000). As a result, consumer-based perspective was selected to measure brand equity. In order to obtain a clear picture of brand equity applied in this study, different types of brand equity perspectives will be discussed in the next section. 25 2.2.2 Financial Perspective Financial perspective of brand equity sometimes was addressed as firm level approach or company-oriented perspective (Feldwick, 1996). This approach measured the brand as a financial asset, which could be defined as either the asset management for manufacturers or leverage for trades (Feldwick, 1996). According to Shocker and Weitz (1988), financial approach explained that brand equity served as a vital role in asset management. This was because it was generally defined as incremental cash flow, which increased market share, premium pricing, and reduced promotional expense from the products with the brand name over unbranded products. These could be further explained by a strong brand that was measured using the brand valuation method, which valued assets of a company by employing momentum of accounting (Farquhar et al., 1991; Farquhar & Ijiri, 1993). However, Barwise (1993) pointed out that accounting system-based measurement was suitable only if all the related information was recorded, and if there was little fluctuation of the future market. On the other hand, Feldwick (1996) defined brand equity as the total brand value as a separable asset, it could be sold out or embraced on a balance sheet; an account of the associations and beliefs of the consumers about the brand or as a measurement of the strength on consumer’s attachment towards a brand. In the trade’s view, brand equity emphasizes the leverage products over other brands in the marketplace, as a strong brand in this sense made it easy to deal with retailers and easy to build a wide distribution (Farquhar, 1989). It had the power to negotiate with middlemen, and, if extended to new products, the product would enter the market more easily (Farquhar, 1989; Shocker & Weitz. 1988). 26 As a conclusion, financially-based measurement was based on the assessment of expenditure and revenue that were derived from companies’ performance and current accounting practices. Furthermore, it highlighted the experimental result from market-share data and assessment of product selling price over its cost. Thus, the measurement of financially-based brand equity included sustainability of cash flow, market share, price premium and financial performance. 2.2.3 Consumer-based Perspective In contrast, Marston (1992) indicated that brand equity reflected customer perceived value, which was formed by the combination of a product’s functional performance, emotional benefits, and consumer’s lifestyle. In other words, it was referred to the positive brand’s impact that was derived from consumer’s evaluation on products or services (Teas & Grapentine, 1996). However, Shocker and Weitz (1988) suggested that brand equity goes beyond the product or service attributes. They further explained that brand equity was a function of associations that had been built and nurtured in the consumer’s mind (Shocker & Weitz, 1988). The existence of strong association would consequently lead to brand attitude (Lutz, 1975). The strength of brand attitude was a major determinant for consumers’ behavior, such as actual purchase (Hwang, Yoon, & Park, 2011). For these reasons, these associations and behaviors permitted the brand to increase its market share and markup margin, which could not be easily exercised by unbranded items or services (Park, MacInnis, Priester, Eisingerich, & Iacobucci, 2010). In addition, there were two different approaches in consumer-based perspective, which were economic-based approaches (Erdem & Swait, 1998) and psychological-based approaches (Aaker, 1991; Keller, 1993; Loken & Roedder, 1993). 27 a) Economic-based Approaches Erdem and Swait (1998) conceptualized economic-based approaches from the customer’s perspective that addressed the issue of how brand delivered added value to customers. Essentially, customers were willing to pay price premiums, or to become loyal to a brand because their expected utility was increased (Erdem & Swait, 1998). This could be illustrated by given the imperfect and asymmetrical information structure; as which customers were uncertain about product attributes or quality by conveying credible product claims and information on a product’s position, brands decreased in both information and perceived costs for customers (Erdem & Swait, 1998). Consecutively, increasing customers’ expected utility. b) Psychological-based Approaches On the other hand, psychological-based approaches proposed that brand was seen as a node in the memory with different types of associations, varying in strength, and linked together (Keller, 1993). According to Loken and Roedder (1993), this approach assumed consumers would connect to a brand by category specific, based on its specific attributes with different types of association that represented in the mind of consumers. There were numerous concepts and principles from psychology and social cognition in developing models of consumer brand-related decisions, such as affect referral mechanisms, attributional processes, accessibility-diagnosticity considerations, expectancy value formulations, and so on (Barton & Robin, 2002). Both Aaker (1991) and Keller (1993) models were the well-established brand equity models that were based on the principles of consumer psychology in various ways. Aaker (1991) approached principally from a corporate and managerial perspective; however it was constituted from the standpoint of consumer behavior. On the other hand, Keller (1993) approach of brand equity was focused on consumer behavior perspectives. 28 2.3 Consumer-based Brand Equity Kamakura and Russell (1993) suggested that consumer-based brand equity as dissimilarity of consumers’ responsiveness between a focal brand and an unbranded product or service. It could be explained as different effects of consumers’ response on marketing efforts of the brands, when both of the given brands have the similar level of marketing stimuli and product attributes (Yoo et al, 2000). McQueen (1991) referred consumer-based brand equity as the different between consumers’ evaluation to the branded product and the product without branding. Lassar, Mittal and Sharma, (1995, p.13) had stated that consumer-based brand equity as “the enhancement in the perceived utility and desirability a brand name confers in a product”. Generally, they defined brand equity as the consumer’s perception of the overall superiority of a product or service carrying that brand name when compared to other brands. According to Aaker (2011), in order for the marketer to make the most relevant consumer-based brand strategy, it was worthwhile to think about which competitors were the real threat. Subsequently conducted comparative analyses and formulated the brand strategy in relation to them. On the other hand, some scholars (Keller, 2003; Shocker, Srivastava & Ruekert, 1994) presented the focus on consumer, which highlighted that the approach should be based on analyzing the responsiveness of consumer to a brand name. However, Erdem and Swait (1998) argued that consumer-based brand equity should be evaluated based on the brand credibility value of a product or service position, more than consumers’ responsiveness. Keller (2001) argued that brand equity occurred when the consumers were familiar with the brand and associated with some strong, favorable, and unique memory towards the brand. For these reasons, consumers would have positive behavior, purchase intention, and preference towards the brand. 29 Keller (1998) further highlighted that brand equity was driven by personal meanings and images. Rust, Lemon and Zeithaml (2001) pointed out that value equity taps into a customer’s head, while Aaker (1997) discovered brand equity addressed what existed in a customer’s heart and soul. Lately, Lovelock and Wirtz (2007) defined it as a more subjective, emotional, and experiential appraisal of a corporation or a brand. According to Heding et al. (2009), Keller’s (1993) customer-based brand equity (CBBE) was derived by consumer-based approach, which indicated brand was the cognitive construal that existed in the consumers’ perception or mind. This assumption also showed that consumers have the full control over the brand-consumer exchange (Heding et al., 2009). Belch and Belch (2009) stated that most of the marketing models considered full set of consumer’s response model (cognitive, affective, conative stage), for instance action, desire, interest, action (AIDA), hierarchy of effects, innovation adoption, information processing. However, CBBE only focused on consumers’ brand image (types of association, favorability, strength, and uniqueness) and brand awareness (Keller, 1993). In other words, it purely based on cognitive and affective processing regardless other component of mind such as conative. In another study by Blackston (1992), brand was the consumers’ idea about the product, while product was what the company physically made. But what the consumers purchased was psychologically and actually a brand, which offered something more than its functionality (Kapferer, 1992), where could be referred as the sequential process of consumers attitudes (Lannon, 1993). As a result, it made this study rational by including the hierarchy of effect theory (causal effects) in explaining brand equity concept. 30 2.3.1 Hierarchy of Effect Theory (Cognitive-affective-conative) Researchers such as Bagozzi (1978) and Breckler (1984) argued that the evaluation of consumers’ response was assumed as people’s attitudes and, thus, it was classified as three distinguishing classes, such as cognition, affect, and conation (Bagozzi, 1978; Breckler, 1984). Cognition was referred to the thoughts towards a particular attitude object, which consisted of belief, mental, “rational” states, intellectual or belief in the statement of fact (Lavidge & Steiner, 1961). Next, the affect could be deliberated by physiological responses or a collection of verbal report, which consisted of emotional responses, feelings and moods. Importantly, Eagly and Chaiken (1993) stated that the affective responses could be exceptionally identified in both positive and negative range, and was positioned on an evaluative dimension of meaning. Oliver (1997) further stated the components of affective responses consisted of caring, involvement, and liking. Most of the time, people provided a favorable evaluation towards an attitude object when there was a positive experience, which directly associated with the positive side of affective reactions (Oliver, 1997). At the same time, people also presented negative affective reactions when they experienced an unfavorable evaluation towards an attitude object (Oliver, 1997). Finally, the conation included behavioral willingness or intentions to act. According to Bagozzi (1978, p. 10), conation was said to “depict the action tendencies one had to approach or avoid an object or perform some response”. Lavidge and Steiner (1961) defined conation as motivational component, such as the “striving” states, which could be referred to both positive and negative tendency to treat an attitude object. 31 The four-stage loyalty theory by Oliver (1997) became one of the most popular applications of hierarchy of effect theory, which gained interest among marketing researchers. Oliver (1997) classified customer loyalty into four different stages in psychological loyalty, namely cognitive loyalty, affective loyalty, conative loyalty, and action loyalty. According to Oliver (1999), cognitive loyalty existed when consumers have preference towards a service provider, this could be based on the identification of its attribute performances and brand information. Oliver further stated that cognitive response was derived by the consumers’ recent experience or vivid knowledge with the firms. Thus, cognitive loyalty was considered as the first stage of loyalty in hospitality industry (Back & Parks, 2003). Affective loyalty could be emerged when consumers have greater form of commitment towards the service provider (Oliver, 1999). In this stage, consumers have an attributed satisfaction towards the product experience; consequently, they not only depended on the attribute performances and brand information, but also on the response of consumers “like” the service provider (Oliver, 1999). The behavior of brand switching for affective loyal consumers would be slightly lower, as compared to cognitive loyal consumers when there was counterargumentation from other brands (Oliver, 1999). This was because consumers were satisfied with the service providers; however, such situation might lead to “satisfaction trap”. This could be supported by there were large number of satisfied consumers who depended on various service providers (Reichheld, 1996). In other words, they were loyal to many brands; as a result, this level of loyalty was still vulnerable to avoid switching behaviors (Oliver, 1999). 32 Conative loyalty could be referred to deeper level of attitudinal commitment that held by consumers (Oliver, 1999). In this stage, consumers would have greater brand commitment and repurchase intention, as they had repeated affirmative cognitive and affective experiences with the brand or service provider (Oliver, 1999). He argued that even though the intention was good, subsequently it did not always serve as the main objective for many managers. This could be explained as to why managers prefer to have financial result, such as the increase of revenue from repurchase behavior, instead of the repurchase motivation held by consumers (Oliver, 1999). For these reason, Kuhl and Beckmann (1985) stated that the mechanism of transforming conative loyalty into real actions should be highlighted. In other words, the focus should be based on the establishment of loyal bond between consumers and a brand, ultimately led to the consumers’ action (Kuhl & Beckmann, 1985). According to Ajzen and Fishbein (1977), action loyalty served as the strongest form of behavioral intention in the behavior formation of attitudinal framework. This was because it combined consumers’ intention and motivation, subsequently led to the readiness to act, such as constant purchase and enhanced regularity of purchase (Bandyopadhyay & Martell, 2007). Even though action loyalty was considered as final stage of loyalty, however the sustainability of action loyalty was heavily depended on conative loyalty (Bandyopadhyay & Martell, 2007; Evanschitzky & Wunderlich, 2006). This could be further supported in a hospitality study, as action loyalty was a positive function of conative loyalty developed through the cognitive and affective stages (Back & Parks, 2003). 33 Based on the above sequential process, many social scientists assumed loyalty phase which was based on cognitive-affective-conative approach, considered to be emerging consecutively rather than concurrently (Back & Parks, 2003; Evanschitzky & Wunderlich, 2006; Oliver, 1997, 1999). As a result, sequential process formation served as an important fundamental theory for the evaluation of consumer, which was also be highlighted in some of the brand equity studies (Agarwal & Malhotra, 2005; Brown, 1998; De Chernatony, 2002; Keller, 2003; Malhotra, 2005). However, the empirical research for sequential process formation was very limited (Da Silva & Sharifah, 2006; Merrilees & Fry, 2002; Sirgy & Samli, 1985; Selnes, 1993). Furthermore, there was no clear categorization of cognitive-affectiveconative on the dimensions of brand equity as defined by Aaker’s (1991) model. Studies show that the application of the hierarchy of effect theory as a general reference for the model development was due to two main reasons. Firstly, it related to the consumers’ response in term of psychological perspective (Barry, 1987). Secondly, it was a general guideline for the development of most of the available marketing models (Belch & Belch, 2009). 2.3.2 Different Dimensions of Brand Equity across Industries Different industries contributed dissimilarity of brand equity dimensions. According to Yoo et al.’s (2000), perceived quality, brand awareness/association, and brand loyalty dimensions were based on athletic shoes, camera film, and television sets. Angel and Manuel (2005) replaced brand association as brand image in durable goods study. Besides, Norjaya et al. (2007) classified the brand equity dimensions of household electrical appliances as brand loyalty, brand distinctiveness and brand association/awareness. Wang, Wei and Yu (2008) suggested that global brand equity consisted of four indicators, such as quality perception, brand awareness, brand resonance, and corporation ability association. 34 Table 2.1: Summary of Previous Finding for Dimensions of Brand Equity Author(s) and Year Dimensions Industry/Product Aaker (1991, 1996) Perceived quality, brand awareness, N/A brand associations, brand loyalty Srivastava & Shocker (1991) Brand strength N/A Keller (1993) Brand awareness, brand image N/A Lassar et al.

Recently, Xu and Andrew (2009) defined the conceptual framework of hotel brand equity as brand loyalty, brand association, brand awareness and quality of experience. For further supporting the argument, Table 2.1 summarizes the variation of brand equity dimensions across different industries or products for the last twenty years. According to Christodoulides and de Chernatony (2010, p. 61), “a brand equity monitor should incorporate dimensions that drive value within the specific industry.” Therefore, both brand familiarity (Schlosser, 2002) and brand trust (Delgado-Ballester & Munuera-Aleman, 2005) were proposed as additional dimensions as they served as important dimensions in the context of fast food (Morgan & Hunt, 1994; Smith, 1993). 2.4 Theoretical Review of Brand Equity As mentioned in the previous section, this study adopted the consumer-based brand equity. The following sections discuss the four theories of the consumer-based brand equity, by Aaker (1991), Keller’s brand knowledge (1993), Lassar et al. (1995), and Gil et al. (2007). According to Faircloth, Capella and Alford (2001), the first three brand equity theories were widely recognized and accepted within the marketing field due to its unique contribution for identifying the degree of difference in consumer behavior effect of the firm’s marketing mix activities. Gil et al.’s theory was included where it implied the hierarchy of effect theory and investigated the causal relationships between dimensions of brand equity. 37 2.4.1 Aaker’s Theory of Brand Equity (1991) There were five dimensions proposed by Aaker’s (1991) brand equity model, namely brand awareness, perceived quality, brand associations, brand loyalty, and other proprietary brand assets. Brand awareness was the ability of the possible customer to recall or recognize brand names or symbols, thus brand would not be chosen if it was not considered (Aaker, 1991). Aaker further supplied evidence with regards to the importance of brand awareness in contributing to brand loyalty, which helped to make the brand more familiar and top-of-mind, where increased the probability of being chosen by the consumers. Perceived quality was referred to as the overall perception of consumers towards the product or service of a brand (Zeithaml, 1988). Positive perceived quality resulted from the supremacy of perception; negative perceived quality was identified from the inferiority of perception (Zeithaml, 1988). Therefore, it was important for the firm to produce an objectively measured quality product and to be able to link the positive quality associations with the brand, consequently could lead to the basis for achieving premium prices (Aaker, 1991). Brand association was linked to the consumers’ memory (Keller, 1993); a strong association to a brand by assisting consumers to process or retrieve information, distinguish the brand, give consumers a reason to purchase, build an encouraging attitude in consumers’ minds, and provide a basis for extending brands (Aaker, 1996; Craik & Lockhart, 1972; Lockhart, Craik & Jacoby, 1976). Brand associations were organized in a manner that reflected brand image, which ranged from very clear to very diffuse (Aaker, 1996). The associations represented the utility received from purchasing or consuming the brand and thus represented the actual or perceived reason for buying behavior (Keller, 1993). Besides, brand associations also provided the key of company’s strategic differentiation and positioning, product recall, development for positive brand evaluations, and extensions (Aaker, 1996). 38 Brand loyalty was defined as a measure of the attachment that customers had to a brand (Back, 2005). Aaker (1996) stated that brand loyalty enhanced brand awareness by ensuring the brand was visible on a continuous basis and offered testimonial reassurance to new customers. In addition to that, he also highlighted that brand equity contributed to other proprietary brand assets, such as patents, trademarks, channel relationships. These were also considered valuable because they protected brand equity from competitors. Thus, brand equity helped to ensure the company’s long-term cash flow, strategic advantage, and reduce marketing costs (Aaker, 1991). Figure 2.1 illustrates how brand equity generated value to the customer and the firm.

It covered the whole circle of value flow from the brand to customers and firms respectively. This could become the major drawback of this theory as it covered a wide range of perceptual and behavioral concepts without operationally define them. Subsequently, later researchers had to adapt the components with their own operational definitions (Anantachart, 1998). 2.4.2 Keller’s Theory of Brand Equity-Brand Knowledge (1993) Keller (1993) defined brand equity as the different effect of brand knowledge on consumer’s response to the marketing of the brand. Brand knowledge was referred to the brand as a node of an associative network memory which linked various types of associations (Collins & Loftus, 1975; Raaijmakers & Shiffrin, 1981; Ratcliff & McKoon, 1988). It was distinct in terms of two components, brand awareness and brand image as presented in Figure 2.2. Keller stated brand awareness could be evidenced when the brand was strongly held in consumers’ memory. Therefore, it reflected an individual’s ability to recognize a variety of brand elements, such as the brand name, logo, symbol, character, packaging and slogan under different conditions (Keller, 1993). On the other hand, brand image was the combination of the favorability, strength, and uniqueness of brand associations, which played important roles in identifying the degree of difference among branded products (Keller, 1993). Besides, it was also referred to as customers’ perceptions of the brand, which included attributes, benefits, and attitudes (Keller, 1993). Attributes, the most concrete level of association, represented the brand’s descriptive features (Myers & Shocker, 1981). Benefits could be conceptualized as the personal value or motivations of the attributes (Park, Jaworski, & Maclnnis, 1986). Finally, brand attitudes were the consumers’ overall evaluation towards the brand (Wilkie, 1986) and was most commonly seen in the context of multiattribute attitude model (Keller, 1993). 40 Brand Recall Brand Awareness Brand Recognition Price Non ProductRelated Brand Knowledge Attributes Types of Brand Associations User Imagery Usage Imagery Functional Benefits Favorability of Brand Associations Brand Image ProductRelated Packaging Experiential Symbolic Strength of Brand Associations Attitudes Uniqueness of Brand Associations Source: Keller (1993) Figure 2.2: The Brand Knowledge by Keller (1993) Keller (1993) indicated that enhanced brand awareness and brand image resulted in increasing consumer brand knowledge, which would cause a differential consumer behavior response to the firm’s marketing mix. This is because higher the levels of recall or recognition would also drive to higher brand equity; whereas positive brand image would increase brand knowledge and logically resulted in greater brand equity (Keller, 1993). 41 In Keller’s model, three types of brand associations were introduced to subsume the level of abstraction (Alba & Hutchinson, 1987; Johnson, 1984), which had differential effect on the formation of brand knowledge. Keller (1993) implicitly noted that the types of associations and the dimensions of strength, favorability, and uniqueness should cause different levels of brand image and brand equity. Keller further provided conceptual support for the impact of brand image and different brand associations on brand choice, which based on the notion of self-concept, product image congruency, and consumer brand preference and choice. The major drawback of this theory was because it focused on the consumer, which highlighted that the marketers or practitioners had to focus on collecting the information or database about the consumer mind of brand association regarding their company brand (brand knowledge and evaluation) (Heding et al., 2009). Consequently, marketing initiatives had to be designed by backward-looking, which had leaded to lack of organizational vision. Furthermore, it may be more complex to measure brand image since it must be evaluated from the characteristics of brand associations, such as favorability, strength, and uniqueness (Anantachart, 1998). 2.4.3 Lassar, Mittal and Sharma’s Theory of Brand Equity (1995) Performance Social Image Trustworthiness Brand Equity Commitment Social Value Source: Lassar et al. (1995) Figure 2.3: The Theory of Brand Equity by Lassar, Mittal and Sharma (1995) 42 Figure 2.3 shows that there were five dimensions of consumer-based brand equity; social image, performance, commitment, value and trustworthiness (Lassar et al., 1995). Performance was referred to as the physical performance of the brand, such as the product itself and service provider. Lassar et al. (1995) indicated the evaluation of performance was related to consumers’ judgment, which included the brand’s error free and ongoing physical operation, and flawless in the products’ physical production. Performance served as a vital element, this was because it would directly affect the consumers’ purchase frequency (Lassar et al. 1995). Consumers would become reluctant to have future purchase intention once they had aversion experience with the brand, such as failure to deliver the required specification, thus led to low levels of brand equity (Anantachart, 1998). Social image could be referred as consumers’ perception of the esteem, and it could be identified as the level of brand that is held by a particular social group, such as the status, social class, social symbol, perception, identity and so on (Lassar et al., 1995). Social image was considered as value added because it enhanced the brand’s social reputation and market value. Most of the time, social image had contributed more to brand equity in fashion related industry, such as clothes, jewelries, perfumes, and beauty products (Anantachart, 1998). Lassar et al. (1995) stated commitment was related to the strength of affirmative feeling held by consumers towards the brand; it was measured in term of perceptual rather than behavioral. This could be further explained as the development of sentimental attachment, which had come about from the positive identification with the brand (Lassar et al., 1995). 43 Value was referred to the perceived brand value in relation to its cost. It highlighted the assessment of brand utility as compared to its price (Lassar et al., 1995). Sometimes, it could be identified as the value of money (Brucks & Zeithaml, 1993). Consequently, higher brand equity was evidenced when the brand provided consumers with higher perceived value; reason being that consumers would always go for a particular brand choice as they perceived the brand could provide them with higher utilities value (Lassar et al., 1995). Lassar et al. (1995) argued trustworthiness was related to the level of consumers’ confidence with the brand and firm’s communications. Furthermore, it referred to the level of firm’s actions in serving the best interest of the consumers (Chaudhuri & Holbrook, 2001). Trustworthiness was included because the consumers placed greater value for the brand when they trusted it, as compared to the distrusted brands (Macintosh & Lockshin, 1997). Correspondingly, the existence of trusted brand positively affected brand equity (Hu, Chang, Hsieh, & Chen, 2010). Each of the dimensions played major implication in enhancing brand equity and there existed with a halo effect across dimensions of brand equity (Lassar et al., 1995). For instance, once there was a positive evaluation on neither one of the dimensions (e.g. performance), the expectation on other dimensions (e.g. social image, commitment, value and trustworthiness) would be set at a higher level. On the other hand, consumers did not place high expectation on other dimensions (e.g. performance, commitment, value and trustworthiness) once there was a failure or negative evaluation on neither one of the dimensions (e.g. social image) (Lassar et al., 1995). This implication showed major drawback of the theory as there was high possibility of a brand which provided greater social image, and did not necessary supply good performance. The performance was something with a functional purpose while a brand offered something more than its functionality; it came from the consumers’ idea about the product (Blackston, 1992; Jones, 1986). Consequently, the claim of halo effect might not represent the true picture across dimensions of brand equity. 44 Besides, Lassar et al. (1995) argued that when consumers have equity towards brands, they would accept higher market price of that brand than other brands with lower or no equity. However, this implication showed inconsistency in fast food industry. For instance, McDonald’s was indicated to have the highest score of total brand equity among Korean consumers, but the product price of McDonald’s was lower than other similar types fast food brands, such as Burger King, Hardee’s, and Lotteria (Kim & Kim, 2004). Subsequently, the relationship between higher brand equity and greater market price could not be generalized. 2.4.4 Gil, Andrés and Salinas’s Theory of Brand Equity (2007) Gil et al. (2007) extended Aaker’s (1991) theory by including the effect of both family and marketing activities on the brand equity formation process. Based on Chiou et al.’s (2002) cognitive-affective-conative hierarchical model, Gil et al. established causal relationship between the dimensions of brand equity. Referring to research framework of Gil et al. (2007), brand loyalty had been considered as an antecedent of other dimensions, based on the hierarchy of effects theory (Lavidge & Steiner, 1961). Their initial literature review proposed brand awareness, brand association and perceived quality had direct effects on brand loyalty and brand equity. Nevertheless, their results indicated that both brand awareness and band association were considered as a joint construct in the structural model. Besides, the findings also showed that there was non-significant direct effect from perceived quality on brand loyalty, highlighting a missed link in explaining perceived quality as an important dimension of brand equity. Consequently, the empirical framework did not support perceived quality as a critical dimension of brand equity (Gil et al., 2007). 45 Source: Gil et al. (2007) Figure 2.4 The Theory of Brand Equity by Gil, Andre’s and Salinas (2007) Gil et al. (2007) also indicated that family information contributed significantly on brand awareness/association and perceived quality. However, they claimed there were difficulties to distinguish between brand awareness and brand association, which was in line with some of the researchers’ findings (see Yoo et al., 2000; Washburn & Plank, 2002). In addition to that, Gil et al. argued that the existence of brand awareness/association and perceived quality were not sufficient to establish the superiority of a brand over other challenging brands, because both of the dimensions were considered as cognitive character, whereas only brand loyalty was considered as the closest dimension to the concept of brand equity (Yoo et al., 2000). 2.4.5 Selection of Brand Equity Theory for the Study For the purpose of this study, Gil et al.’s (2007) theory was adopted and modified to generate a meaningful research in examining the attitudes of Malaysian fast food consumers. The main reason was because the model was adequately extended and integrated i.e. the theory of both brand equity (Aaker, 1991) and hierarchy of effects (Lavidge & Steiner, 1961). The details of the explanations were illustrated in the following section. 46 Firstly, Gil et al. (2007) clearly identified the causal relationships among the dimension of consumer-based brand equity based on the explanation of cognitiveaffective-conative, which served as a justification for the establishment of causal effect that provided better explanation than some of the recent studies (e.g. Boo et al., 2009; Hess et al., 2011; Patwardhan & Balasubramanian, 2011; Pike et al. 2010; Rosa & Riquelme, 2008; Sanyal & Datta, 2011; Xu & Andrew, 2009). Secondly, Gil et al. (2007) categorized the dimensions of consumer-based brand equity with theoretical justification. For instance, perceived quality and brand awareness/association were considered as cognitive constructs, while brand loyalty was considered conative construct. The main advantage of this approach was this could lead to the better development of measurement items, which to ensure there were clear operational definition of the constructs and no overlapping of the observed variables (Gil et al., 2007). Thirdly, Gil et al.’s (2007) study used a sample of actual consumers (nonstudent). Consequently the results were more open to generalization (Pappu & Quester, 2008). Besides, the selection of products/brands was based on the level of involvement that derived from the perception of consumer rather than the inherent characteristic of the product itself (Malär, Krohmer, Hoyer & Nyffenegger, 2011). For instance, they conducted a pre-test to indicate the degree of brand familiarity and level of usage. This was because the high degree of respondents’ brand familiarity and brand experience served as important criteria to ensure the reliability and validity of the questionnaire. As a conclusion, this study extends Gil et al.’s (2007) research framework by investigating greater numbers of causal relationships between brand equity dimensions. This study also examined the importance of two additional dimensions, which were brand familiarity and brand trust (Delgado-Ballester & Munuera-Aleman, 2005; Schlosser, 2002). However, marketing activities and family information were excluded from this study due to the objectivity of research study. 47 2.4.6 Development of Brand Equity Theory for the Study The development of the conceptual framework for fast food context was discussed in the next paragraphs, such as replacement of brand association with brand image, the inclusion of brand familiarity and brand trust, brief justification for the selection of attitudinal brand loyalty, and the integration of cognitive-affective-conative. Muller and Woods (1994) pointed out the importance of restaurant brand management instead of product management. They proposed the concept for the development of brand image depended on the brand name, which was vital in maintaining restaurant business. Muller (1998) highlighted that restaurant firms should focus on three key areas, which were the execution of service delivery, quality products and services, and the establishment of symbolic and evocative image. He further argued that these strong combinations had been attributed to opportunity for accusing price premium and developing customer loyalty. Although the brand equity concepts for Aaker (1991) and Keller (1993) were conceptualized in a different way, but, both theories focused on customer perspective and illustrated the importance value of brand equity or brand knowledge on the firms and consumers. As a result, brand image was reasonably proposed to replace brand association because fast food industry was grouped under the hospitality industry. Furthermore, brand association had been substituted with brand image in most of the hospitality research (see Henry et al., 2010; Kayaman & Arasli 2007; Kim & Kim, 2004, 2005). Referring to consumers’ brand knowledge, the assessment of brand personality was expected to be affected by consumers’ knowledge and familiarity (Alba & Hutchinson, 1987). Furthermore, Aaker (1996) argued that brand recognition reflected familiarity and linking as acquired from past exposure. As a result, it was safe to include brand familiarity. 48 With respect to brand trust, this study also included trustworthiness, which was used by Lassar et al. (1995); however, trustworthiness was defined as brand trust in this study. Brand trust was considered as a vital dimension to be evaluated in the fast food industry (Delgado-Ballester & Munuera-Aleman, 2005), the reason being to evaluate the affective response on the consistency of business operation and performance. According to Chaudhuri and Holbrook (2001), brand loyalty could be classified as behavioral brand loyalty and attitudinal brand loyalty. Attitudinal brand loyalty was selected because it was based on consumers’ commitment rather than consumers’ actual purchase behavior (Bloemer & Kasper, 1995), which served as an important and relevant outcome of other brand equity dimensions, and also was indicated as the closest element to the concept of brand equity (Zinnbauer & Bakay, 2004). On the other hand, behavioral brand loyalty was referred as spurious loyalty; this is because it refers as the physical continual buying behavior of consumer without any attachment of emotional or psychological (Bloemer & Kasper, 1995). Consequently, the dimensions of consumer-based brand equity for this study were perceived quality, brand awareness, brand familiarity, brand trust, brand image and attitudinal brand loyalty. In addition, this study categorized the dimensions of fast food consumer-based brand equity into cognitive-affective-conative. This is because such different stages of consumer passes had provided useful diagnostic information to the academicians and practitioners (Agarwal & Rao, 1996). The concept of this study was in line with the concept of advertising as proposed by Lavidge and Steiner (1963), which indicated that consumers would not transformed to a convinced purchasers without any sequential consumer’s behavior. Therefore, in order to have strong commitment with a brand, consumers have to go through a series of steps, such as cognitive, affect and conative (Barry, 1987). 49 The statement was further supported by consumers’ affective and emotional were derived from cognitive evaluation, based on research of consumer behavior and psychology (Oliver, 1997, Franzen & Bouwman, 2001). Therefore, positive cognition evaluation (via functional/utilitarian reason) would result first, and then led to affective or emotional, finally drove to conative and behavior intention (Da Silva & Sharifah, 2006). However, Petty, Cacioppo and Schumann (1983) stated that the high-low level of involvement should be considered when applying the concept of cognitive-affectiveconative. Involvement was referred as the mental readiness, such as the cognitive response towards a particular consumption object or brand (Park & Mittal, 1985). The level of involvement was depended by the degree of personal relevance or importance, which could be referred to the consumer’s degree of interest or arousal for a given object (Celsi & Olson, 1988; Richins & Bloch, 1986). Therefore, the high and low involvement of product was depended on the perception of consumer rather than the inherent characteristic of the product itself (Malär et al., 2011). This could be further supported by Marsden (2006), indicated 750,000 consumers who had treated daily Procter & Gamble product, for instance soap and laundry detergent as high involvement products instead of low involvement products. As a result, it was safe to apply the concept of cognitive-affective-conative into brand equity study, such as fast food brand because consumers would treat the brand as high involvement due to the existence of emotional brand attachment (Malär et al., 2011). This could be further supported by some brand equity studies, which had used the products that were inherently characterised as low involvement, such as candy bars (Agarwal & Rao, 1996), milk, toothpaste and olive oil (Gil et al., 2007), disposable razors and potato chips (Grimm, 2005), and bookstore (Da Silva & Sharifah, 2006). 50 2.5 Perceived Quality According to Zeithaml (1988), perceived quality was not referred to the actual quality of the products or services; it was related to the overall perception of consumers towards the product or service of a brand. Positive perceived quality could be the result from the supremacy of perception that resulted from its deliberated function, compared to other alternatives (Zeithaml, 1988). On the other hand, negative perceived quality could be identified from the inferiority of perception (Zeithaml, 1988). Aaker (1991) stated that perceived quality was not only just another brand association, it was importantly related to the status of a brand, and thus it served as a separate dimension of brand equity. Quality was materialized as the primary criterion for the brand choice. Researchers advocated that perceived quality was measured as a core or primary facet across the frameworks of brand equity (Dyson, Farr & Hollis, 1996; Farquhar, 1989; Keller, 1993). Aaker’s (1991) surveys discovered that quality was the most significant consideration of selection. Research conducted by Michell, King and Reast (2001) further affirmed that quality, reliability, and performance ranked first, second, and third positions respectively. Therefore, perceived quality was consistently proven as an essential criterion. According to Aaker (1991), positive perceived quality could influence consumers’ selection, motivate consumers in making purchase decision, brand differentiation, serve as a basic for brand extension, and provide opportunity for charging a price premium. Aaker also linked perceived quality to corporate profitability. Here, it was important for the firm to produce an objectively measured quality product and to be able to link the quality associations with the brand. 51 Unfortunately, Aaker (1991) justified that perceived quality could not be reasonably determined due to its intangibility. The characteristic of intangibility stemmed from the perception and judgment of what is considered important to the customers involved. Therefore, in order to be successful, firms must be able to identify attributes that consumers were looking with regards to quality. Firms must be able to define perceived quality attribute specific to the industry and recognize the cues or signals that exist for perceived quality (Aaker, 1991). Although perceived quality was unquantifiable, it was usually determined based on the characteristics of the goods and services, namely the reliability and performance to which it was branded (Aaker, 1996). Besides, there existed a link between perceived quality with price elasticity, stock return, price premiums and brand usage (Aaker, 1996). Additionally, communication on the quality of its brands had to be done through quality signals in marketing efforts. Grönroos (1984) showed that consumers perceived brand quality through first-hand experiences with the brand and also via information acquired from surrounding environmental. In the service industry, perceived quality could be classified into two types. Firstly, it was referred to as the service quality that provided physical facilities, such as business hours, physical environment, and modern equipment (Kim & Kim, 2005). Secondly, it was referred to the service quality that provided by employees, such as courtesy, responsiveness, and helpfulness (Kim & Kim, 2005). As a conclusion, perceived quality was considered as an important measurement in the food service industry as there were many social scientists had ensured that service quality was the primary cognitive assessment of service provider at the attribute level (Chiou et al., 2002; Dabholkar, 1995; Donovan, Rossiter, Marcoolyn & Nesdale, 1994; Parasuraman, Zeithaml & Berry, 1988). Furthermore, practitioners must be able to identify which attributes consumers were looking for in regard to quality for the purpose of brand equity creation (Tan et al., 2011). 52 2.6 Brand Awareness Aaker (1991) indicated that brand awareness was the capability of prospect buyer to recognize or recall a particular brand when in the selection process of certain category of product. However, Alba and Hutchinson (1987) defined it as the level of consumers’ brand exposure. Woodward (2000) argued that a consumer’s brand awareness would be higher as his or her exposure to the brand increased. Grover and Srinivasan (1992) stated that brand awareness could be enhanced in different marketing activities such as advertising, communication, direct mail, promotion activities, trade press, and word-of-mouth. Valkenburg and Buijzen (2005) suggested that brand awareness was commonly referred to an individual’s active and passive knowledge of a specific brand. Therefore, Aaker (1991, 1996) proposed it as the consumers’ ability to associate a brand with its product category, referred to the strength of a brand’s presence in the consumer’s mind. Moreover, Hoyer and Brown (1990) represented it as a basic level of brand knowledge. Brand awareness could be evidenced when the brand was strongly held in consumers’ memory (Keller, 2003). Therefore, it was reflected by an individual’s ability to recognize a variety of brand elements, such as the brand name, logo, symbol, character, packaging and slogan under different conditions (Keller, 2003). Keller (1993) indicated brand recognition and brand recall as the two core subdimensions of brand awareness. Basically, brand recognition was related to the level of consumers’ ability to confirm a particular brand without any assistance of the brand cue or brand information. This could be further explained as the recognition level of brand attributes or communications among consumers (Keller, 1998). Mandler (1980) discovered brand recognition could also be characterized as the process of perceiving a brand that is based on encountered experience in the past. 53 On the other hand, Keller (1998) defined brand recall as the ability of consumers to recover or regain the brand when given some cues, such as product category, and purchase or usage situation. That is, individuals would specify a particular brand name, without further delay when given the product category or purchase situation (Keller, 1998). Keller (2003) further indicated that brand recall was seen as a more advanced level of brand awareness than brand recognition as recognizing a brand was easier than recalling it from memory in general. Macklin (1996) explained that there was a high possibility for consumers to recognize a brand, but less likely to recall it. Nevertheless, Keller (2003) highlighted that both brand recognition and recall influence consumer’s decision making. Hoeffier and Keller (2003) determined in their research that brand awareness was characterized into two distinct ways; through depth and breadth. Depth referred to how easily customers could recall or recognize the brand, while breadth referred to the range of purchase and consumption situations in which the brand came to mind (Keller, 2003). In addition, Hoeffier and Keller (2003) established the strength of brand awareness when the consumer could recall “known” brands versus “unknown” brands when making purchase decisions. This was accomplished by linking the brand to memory through such things as the brand name, a logo, a symbol, or even a tag line. However, Ye and Raaij (2004) suggested that the most effective way to build strong brand awareness in consumers’ memory is to attract their attention. Because different response tasks (e.g., recall, recognition) invited different types of processing, and the findings underscored the notion that related to a particular measure of advertising effectiveness which depended on whether that measure truly captured the demands of consumers confronted in the relevant purchase or consumption context (Meyers-Levy & Maheswaran, 1991). 54 For example, it would seem that recall would be a valuable indicator of advertising effectiveness only if, in the ultimate decision context, when consumers were likely to retrieve specific advertising claims when making a purchase decision, as they appeared to do during recall (Meyers-Levy & Maheswaran, 1991). Besides, brand awareness was the simplest level of cognitive response, and it was the knowledge for the existence of a product or a brand (Alba & Hutchinson, 1987; Hoyer & Brown, 1990). It could be determined by the percentage of potential buyers who named the company as the first brand that had came to mind in a particular product category. Based on the literature review as stated above, brand awareness was considered as a vital dimension in the context on fast food industry as brand awareness was the prerequisite for brand equity (Heding at al., 2009). If the consumer was not aware of the brand, it was not relevant to talk about brand equity in the first place; then the company competed on the product rather than the brand (Aaker, 1991; Tan et al., 2011). Nevertheless, this study considered brand awareness as a uni-dimensional construct rather than multi-dimensional (e.g. brand recall, brand recognition). This was because it would lead to the simplicity of research process. 2.7 Brand Familiarity Mano and Davis (1990) defined brand familiarity as product familiarity which related to the number of product experiences that a consumer had. Marks and Olson (1981) discovered another view of brand familiarity, which focused on information processing. Brand familiarity, in this view, referred to the cognitive representations of experiences stored in memory instead of prior experience with a brand (Marks & Olson, 1981). These cognitive representations of experiences with a brand were organized in the memory as a structure or schema in the form of representations for brand names, attributes, uses, choice criteria, and so on (Marks & Olson, 1981). 55 Based on this information processing view, brand familiarity was a continuous variable (Kent & Allen, 1994). Thus, people with different cognitive structures or schemas varied in their levels of brand familiarity. Phelps and Thorson (1991) pointed an alternative view of brand familiarity, which was the amount of time spent in processing of brand information regardless of the type or content of processing that was involved. The greater the amount of time spent in processing brand information, the greater the level of familiarity with that information, regardless of whether the type of processing was semantic (e.g., words, name, logo) or sensory (e.g., pictures, attributes) (Bettman, 1979). According to Das, Stenger and Ellis (2009), brand understanding required greater degree of cognitive response, such as brand familiarity, where the greater time the consumers were involved with the brand, the higher their degree of familiarity and these lead to higher probability of brand choice. As a result, brand awareness alone was not sufficient to create a satisfactory level of understanding (Das et al. 2009). Alba and Hutchinson (1987) defined brand familiarity as the number of brandrelated experiences that a consumer had built up. Thus, it emphasized the direct and indirect knowledge available to the consumer. On the other hand, brand familiarity was referred to the total time spent processing information about the brand (Baker et al., 1986). The familiarity of a brand might be due to physical factors such as, its newness and age in the market (Carpenter & Nakamoto, 1989), as well as competitive factors such as its prominence and positioning relative to other brands (Hoyer & Brown, 1990). Besides, Kent and Allen (1994) converged on the significance of brand familiarity as an important moderator on consumer response to various types and forms of advertising. Consequently, brand familiarity moderated the influence of emotional advertisements on brand evaluations (Machleit & Wilson, 1988). 56 In addition, Kent and Allen (1994) proposed brand familiarity moderated the effects of competitive advertising interference. Campbell and Keller (2003) also argued that brand familiarity attenuated the negative effects of wear-out caused by providing repeat advertisements. Typically, this study identified brand familiarity as wellestablished through cognitive representations of knowledge that stored in memory with the brand, as consumers became familiar with the brand; they were more likely to perceive the brands’ relevance (Aaker, 2011). The role of familiarity also appeared to be far greater for the situation where the consumer was looking for a simple rule for decision making (Batra & Ray, 1985), such as fast food. Schlosser (2002) expressed the flavors of childhood food which had left an indelible mark, and where adults often returned to them, without always knowing why. As a conclusion, brand familiarity was considered as an important donor to fast food brand equity as it drove to positive attitude towards the brand, consumer confidence, and purchase intention (Laroche et al., 1996). 2.8 Brand Image Brand image is an essential element in marketing research (Paul, Gary, & Hsiao, 2010). Keller, (1998 p. 93) defined it as “perceptions about a brand as reflected by the brand associations held in consumer’s memory”. Keller (1993) in his research used brand image as a vital element of brand equity; and brand personality (Aaker, 1997) as an indicator of brand image. The term of brand image had been broadly defined and used in various ways. However, Dobni and Zinkhan (1990) stated a general definition of brand image, which was referred as the development of overall impression towards a specific brand, subsequently; this cognitive construal would affect both perception and emotion of the person while interact with that brand. In term of consumers’ perspective, brand image was stored in the minds of consumers and was affected by how consumers developed, maintained, and gave meaning to the influence of personal experienced on the 57 stimulated brands (Keller, 1993). Bullmore (1984) stressed that the creation of brand image was due to an individual psychological center (individual psyche); the opposite of the image belonged to the nature of assumptions and to respond to the image with goodwill was possible only in individual mind. In term of mentality, the creation of brand image was resulted from the experience of the consumer through coordination and stimulation (Harris & de Chernatony, 2001). In view from the marketers’ perspective, brand image was determined by the selection of marketing personnel, development, implementation and management, and acceptance of consumers in creating image (Park, 2009). Consumers were assumed to have passive roles in developing or changing a particular brand image in the market place (Dobni & Zinkhan, 1990). Both Aaker (1996) and Keller (1998) described brand image as attributes and associations that consumers connected to the brand name. These “evoked associations” was referred to specific perceptions of functional attributes, such as speed or user friendliness (Aaker, 1996; Keller, 1998). In addition there could also be emotional attributes, such as excitement, masculinity, fun, or innovation (Keller, 2003). In term of brand knowledge, Keller (1993, 1998) presented that brand image was the combination of the favorability, strength, and uniqueness of brand associations. He further identified that favorability, strength, and uniqueness were the dimensions that played an important role in identifying the degree of different response on branded products. For this reason, a positive brand image was created, if it had unique, favorable, and had strong associations linked to the brand (Keller, 1993). Keller (1993) further proposed that brand image was composed of image drivers. This could be explained by the association between the brand name and intangible symbolic benefits as perceived by consumers, which served as platform to satisfy consumers in term on social class, self-emotional, and any other perception of needs. Neal and Bathe (1997) further argued that the image drivers were also referred to lifestyle, trustworthiness, and self-concept. 58 According to Dobni and Zinkhan, (1990), many researchers had applied different kind of technical and casual application on deriving the measurement and categorization of brand image (Park, 2009). Nevertheless, there was no consistency of measurement for the dimensionality of brand image (Dobni & Zinkhan, 1990). For instance, Park et al. (1986) proposed brand image could be measured in term of how consumers perceived the unique meaning of the brand, in term of its functionality, experiential, and symbolic benefits. In the same vein, Hsieh (2002) argued the dimensionality of brand image should be measured in term of its sensory, utilitarian, economic, and symbolic. Interestingly, some researchers found that functional and symbolic as vital concepts of brand image (Bhat & Reddy, 2001; Dobni & Zinkhan, 1990; Sirgy & Samli, 1985). Functional brand image was likely to be referred to by product-related attributes of the brand; in other words, inherent characteristics of the brand to execute its utility. In the product category, Grace and O’Cass (2002) identified that reliability, design quality and other features of the core product could be examples of product-related attributes that formed a functional brand image. In contrast, symbolic brand image was most likely referred to as non-product related attributes of the brand. Referring to Keller (1993), it could be generally acquired from extrinsic characteristics of the brand to satisfy higher-level needs of consumers, such as social approval needs or personal expression that maintained or increased their self-esteem. Besides, Kandampully and Suhartanto (2000) highlighted the symbolic of brand image attributes could be referred to the shop layout, environment, reputation, physical appearance such as renovation. On the other hand, Dobni and Zinkhan (1990) highlighted brand image could be assigned to blanket definitions, emphasized on meanings or messages, personification, psychological, and symbolism dimensions. On the destination image side, researchers defined brand image as a multidimensional construct that consisted of two primary characters, namely cognitive and affective destination image (Lawson & Band-Bovy, 1977). 59 Social scientists defined cognitive destination image as the knowledge and belief of physical attributes. On the other hand, affective destination image was related to the affective quality feelings of attributes and the surrounding environments (Baloglu & Brinberg, 1997; Burgess 1978; Baloglu & McClearly, 1999; Gartner, 1993; Genereux, Ward & Russel, 1983; Hanyu, 1993; Holbrook, 1978; Proshonsky, Fabian & Kaminoff, 1983; Walmsley & Jenkins, 1993; Ward & Russel, 1981; Zimmer & Golden, 1988). Even though both of the dimensions could naturally be differentiated, however, many researchers argued that they were also interrelated (Crompton, 1979; Mayo & Jarvis, 1981; Woodside & Lysonski, 1989). This was because cognitive evaluation relied on the affective appraisals of attitude objects, and affective response, such as pleasure and exciting were formed as a function of the cognitive assessment (Gartner, 1993; Holbrook, 1978; Russel & Pratt, 1980; Stern & Krakover, 1993). As a conclusion, brand image was considered important to be included in this study. These were because fast food consumers may be more prone to choose brands for overall perceptions and images than for objective product attributes (Boulding, 1956; Ogilvy, 1985). That is, consumers choose fast food brand images, not fast food products for decision making. This could be further explained that brand image served as a foundation for the brand ultimately meeting the consumers’ needs (Park et al., 1986). 2.9 Brand Trust According to Doney and Cannon (1997), trust had been classified as two different dimensions, namely perceived credibility and benevolence. Perceived credibility was focused on the objective believability of an exchange partner, which could be referred to the level of expectancy that someone could rely on, neither verbal nor nonverbal (Doney & Cannon, 1997). Perceived benevolence was related to the extent to which someone was authentically fascinated in the other’s interests and the enthusiasm to search for mutual benefits (Doney & Cannon, 1997). Furthermore, Doney and Cannon emphasized that notion of trust was only applicable in condition of 60 uncertainty. This could be further supported as consumers felt comfortable on trusted brand because trust increased their confidence level in the uncertain environment (Chaudhuri & Holbrook, 2001). In contrast, other researchers (Aaker, 1996; Lasser et al., 1995) defined brand trust as the consumers’ readiness to believe on a particular brand, referred to its capability of promised functionality and attributes, which the value of brand had achieved greater satisfaction as expected by the consumers. Apart from that, Anderson and Weitz (1989, p. 312) referred brand trust as “one party’s belief that its needs would be fulfilled in the future by actions undertaken by the other party.” According to Delgado-Ballester and Munuera-Aleman (2001), brand trust was defined as the level of brand in achieving consumption expectations, which resulted in a feeling of security towards the brand. They further identified that consumerrelationship brand trust consisted of only one dimension instead of two general dimensions that exists in marketing literature, such as brand reliability and brand intentions. Brand reliability implied brand as a promise of future performance, which could be referred to the ability of the brand to fulfill its consumer’s need (Deighton, 1992). For instance, offering a constant quality level and updated products or services to consumers. On the other hand, Michell, Reast and Lynch (1998) referred brand intention to affective response and emotional roots. As it supported the brand by ensuring consumers would not experience from any unwillingness incidents again as this dimensions concerned with the belief that the latter was not going to take opportunity advantage of the former vulnerability (Delgado-Ballester & MunueraAleman, 2001). 61 Drawing on conceptualizations of trust in the social psychology literature, researchers differentiated cognitive and affective trust in the following definition, instead of brand reliability and brand intention (Lewis & Weigert, 1985). Cognitive trust was based on based on evaluating the competence, reliability, and predictability of the trusted object and reflects the economic understanding of trust as a rational choice (Lewis & Weigert, 1985; Riegelsberger et al., 2005; Johnson & Grayson, 2005). It could be assumed that cognitive trust towards a specific brand was greater when the utilitarian value of the product in terms of quality or convenience was high (Chaudhuri & Holbrook, 2001). On the other hand, affective trust was the emotion-driven form of trust that was based on instant affective reactions, signals of benevolence, aesthetics, and attractiveness. Frequently trust-based behavior resulted from a mix of affective and cognitive trust (Corritore et al., 2003; Riegelsberger et al., 2005). For instance, products with a high pleasure had provided non-tangible, symbolic benefits and were likely to hold a greater potential to evoke positive emotions and affect-based brand trust. Apart from definition and conceptualization, trust had become one of the key variables in discussions of relationship marketing (Macintosh & Lockshin, 1997). Relationship marketing could be referred to development of long term and value-laden relationships with patrons and business partners, as well as with other stakeholders (Kotabe & Helsen, 2001). Morgan and Hunt (1994) indicated that both commitment and trust were necessary for the successful of relationship marketing. In their study of commitment-trust theory, trust had a positive impact and was a key determinant and necessary antecedents of relationship commitment and cooperation. Accordingly, trust and commitment were major factors in the formation, development, and maintenance of interpersonal and marketing relationships (Morgan & Hunt, 1994). Based on the commitment-trust theory of Morgan and Hunt, it was obvious that trust was a key factor in collaborative relationships with customers in business marketing (Lau & Lee, 1999). For these reasons, the management of customers’ trust was particularly vital in service marketing (Zboja & Voorhees, 2006). This could be further supported by consumers would never know the outcome of service before it was delivered, and in 62 most of the time, consumers did not have the absolute judgment to differentiate the performance of service provider even they had experienced it (Trawick & Swan, 1981). Chiou et al. (2002) highlighted that trust preceded satisfaction for three main reasons. Firstly, customers’ satisfaction would not be existed if consumers did not have trust appraisal with service provider from past experience. Secondly, based on social exchange theory, customers’ pre-exchange trust would positively relate to postpurchase satisfaction, which explained the formation of causal relationship from trust on satisfaction (Singh & Sirdeshmukh, 2000). Thirdly, it was evidenced in the study of long-term relationships experience. According to Gwinner, Gremler and Bitner (1998), there are three major components of benefits, which consisted of confidence benefit, social benefit, and special-treatment benefit. The confidence benefit was considered as the most important elements (Gwinner et al., 1998). This was because it served as the purposes to reduce anxiety, diminish risk perception, and increase confidence level of service providers (Gwinner et al., 1998). Subsequently, the overall satisfaction could be enhanced when consumers felt confidence benefit, where it was relatively similar to the characteristic of trust value (Chiou et al., 2002). For the purpose of this study, affective brand trust was selected as it served as a function in investigating the affective component of attitude, such as feeling held by an individual or a group that is based on psychological perceptive. Cognitive brand trust could be referred to perceived quality that had been discussed in pervious section. As a conclusion, brand trust was considered to be a significant contributor to fast food brand equity; consumers were more likely to trust the quality of fast food brands and prepared to pay more for the reliability impact of brand quality that the brands imply (Rubinstein, 1996). This could be further explained as the consumer-brand relationship became a promising framework to explain the value of fast food brands to consumers (Fournier, 1998; Morgan & Hunt, 1994). 63 2.10 Brand Loyalty Oliver (1997) referred brand loyalty referred to propensity of loyal consumer to treat a focal brand as primary choice, prolong to buy a product or service of focal brand even the alternative choices were superior, lower price and convenience. Apart from that, Schoell and Guiltinan (1990) identified brand loyalty as the degree to which a buying unit, such as a household, concentrated its purchases over time on a particular brand within a product category. That is, it was related to the exclusive purchase, and where a consumer constantly re-purchased for a particular brand, where repurchase intentions appeared an as important conceptualization of loyalty construct (Brown, 1952). Griffin (1997) stated repeat patronage as the most crucial attitude for the creation of loyalty and highlighted both loyalty and purchase cycle by representing the repurchase loop. He further stated that the consumer would keep on changing or testing other brand if there was no existence of loyalty on a focal brand. Historically, brand loyalty was measured behaviorally via repeat purchase. Conversely, Keller (1998) argued that there were more broad views instead of simple purchase behaviors to measure brand loyalty, such as low level of brand switching. Brand switching happened when the consumer had increased their willingness or desire to accept other alternative brands, subsequently; the existence of brand loyalty would be decreased (Keller, 1998). Bowen and Shoemaker (1998) stated a loyal customer was less probability to switch to another competitive brand simply due to price difference, and indicated that a high frequency of repurchase behavior as compared to non-loyal customers. However, Ehrenberg (1988) argued that loyalty did not exist in consumer perspective and the concept was unclear. Researchers proved that there was no support from any empirical study of non-brand switching behavior among majority of loyal consumers (Klein, 2001; Trivedi & Morgan, 1996). McAlister and Pessemier (1982) indicated that intrinsic and extrinsic motivations affected brand switching behavior. For instance, variety of options played a major role in intrinsic motivations (McAlister & Pessemier, 1982) and the switching behavior could be the result of attribute satiation (Zuckermann, 1979) or either curiosity (Sheth & Raju, 1974). 64 Besides the definition, the measurement for brand loyalty also expressed in various way; for example self-concept, social cost and image (Auty, 2001), satisfaction, perceived value and brand familiarity (Wood, 2004), usage experience and convenience (Rowley, 2005). Rust, Ambler, Carpenter, Kumar and Srivastava (2004) advocated that brand loyalty had been accepted as a popular and credible metric of marketing success in the market. Therefore, building brand loyalty was a worthy marketing objective which should result in providing warrant business success and revenues (Kumar et al., 2004). For instance, Brand loyalty had generated cash flow to a firm and also contributed brand profitability (Chaudhuri & Holbrook, 2001; Howell, 2004). This was because brand loyalty enhanced efficiency and effectiveness of marketing programs by reducing expenditure on promotion, giving competitive advantage, and providing a platform for development through brand extensions (Chaudhuri & Holbrook, 2001; Howell, 2004). Furthermore, loyal customers are happily paid premium prices for the benefits and quality of the brand that alternative brands could not provide (Aaker, 1991). In addition, Gremler and Brown (1996) further stated three specific component of loyalty in service context, which were the purchase, attitude and cognition. On the other hand, Ha (1998) stressed that the development of brand loyalty measurement were recommended to be identified in three distinctive aspect, namely cognitive response, subjective norm, and purchase behavior. Apart from the above arguments, Morgan (2000) classified that there were different interpretations of loyalty, ranging from affective loyalty (“what I feel”) to behavioral loyalty (“what I do”). Nevertheless, Chaudhuri and Holbrook (2001) indicated the most commonly perspective of brand loyalty were behavioral and attitudinal perspective. They further recommended that behavioral loyalty had a tendency to expand to greater market share, while attitudinal loyalty had led to greater relative brand pricing. Both behavioral and attitudinal brand loyalty are discussed in the next section. 65 2.10.1 Behavioral Brand Loyalty Ehrenberg and Goodhardt (2000) defined behavioral brand loyalty as focusing on the consistency of consumers’ actual buying behavior towards a particular brand, this could be explained by a consumer who only considered a particular brand when repurchased a product, without seeking on brand-related information. In other words, these could be referred to as consumers’ repeat purchasing behavior towards a brand without considering the consumers’ intention (Ehrenberg & Goodhardt, 2000). Alternatively, Dick and Basu (1994) explained behavioral aspect of loyalty, which focused on a measuring the proportion of consumer’s prior purchase of a specific brand to the certain purchase habit. Schoell and Guiltinan (1990) defined it as the degree to which a purchasing unit, such as a household, had focused its purchases over time on a particular brand within a product category. Behavioral approaches outfitted loyalty in four ways. First, measurement based on the actual consumption of the goods or services (Veloutosou, Gioulistanis & Moutinho, 2004). Researchers suggested it as combination of volume and frequency of consumption over prescribed time periods (Lin, Wu & Wang, 2000; Veloutosou et al., 2004). Ehrenberg (1988) highlighted that marketing practitioners also had put a great amount of effort to categorize the purchaser patterns, such as frequent purchasers and heavy purchasers. Secondly, behavioral loyalty concept was clearly fell within class of measure, which focused on the amount of brand consumptions within a nominated retail location or defined market (Driver, 1996; East, Harris, Willson & Hammond, 1995). 66 Thirdly, it measured based on the probability of repeated purchase (Brown, 1952). Lastly, Tsao and Chen (2005) described this behavioral approach as examination of time where consumers switched to other brands. In this perspective, researchers measured behavioral loyalty as patterns of actual customer purchase by asking consumers as to how often they purchased certain brands or services (Back & Parks, 2003; Pritchard, Havitz & Howard, 1999 ; Reynolds & Arnolds, 2000). 1 Bloemer and Kasper (1995) characterized spurious behavioral brand loyalty as repeated purchasing behavior without any attitudinal or psychological bonding brand attributes and distinguished it from true brand loyalty, which was a function of psychological processes based on brand commitment. As a conclusion, behavioral aspects of loyalty could be referred as spurious loyalty, such as simple repeated purchase behavior without emotional or psychological bonding; true loyalty referred to attitudinal aspects of loyalty with consumers’ commitment (Bloemer & Kasper, 1995). 2.10.2 Attitudinal Brand Loyalty According to Caruana (2002), attitudinal brand loyalty was measured by psychological commitment to the target object. A consumer was defined as attitudinal brand loyally when he or she expressed positive preference and commitment towards a brand (Bloemer & Kasper, 1995). Besides, Farr and Hollis (1997) specified attitudinal brand loyally on the consumer’s expression instead of physical action, such as consumers’ beliefs, affection, and intention (Jacoby & Chestnut, 1978). Subsequently, Oliver (1997) further discovered that attitudinal brand loyalty could be extended to a chain of consumer favorable attitude towards a particular brand, which is the commitment of consumer with the explanation of cognition, affect, and conation. 67 Importantly, the classifications of three phases were in line with general explanation of attitude (Ajzen, & Fishbein, 1977). Bagozzi (1978) and Breckler (1984) argued that consumers’ evaluation was derived from different level of responses, and these responses could be referred to as people’s attitude. Cognition could be referred to as people’s thoughts about the attitude object, which consisted of belief, mental, “rational” states, intellectual or belief in the statement of fact (Lavidge & Steiner, 1961). Affect could be deliberated by physiological responses or a collection of verbal reports, which consisted of emotional responses, feelings and moods (Lavidge & Steiner, 1961). Eagly and Chaiken (1993) further stated that the affective responses could be exceptionally identified in both positive and negative range, and was positioned on an evaluative dimension of meaning. Conation was defined as motivational component, such as the “striving” states, which could be referred to both positive and negative tendency to treat an attitude object (Lavidge & Steiner, 1961). According to Back and Parks (2003), based on the general components of attitude, sequential process could be evidenced in attitudinal brand loyalty as consumers would become “loyal first in a cognitive sense, then later in an affective sense, and still later in a conative manner” (Oliver, 1997, p. 392). This could be further explained as consumers first, became cognitively loyal that based on the belief on brand attribute (Oliver, 1997). Next, consumers had turned out to be affectively loyal, indicating quality feeling such as exciting and pleasure (Oliver, 1997). Lastly, consumers had become conatively loyal, revealing a brand-specific commitment (Oliver, 1997). Consequently, this sequential justification was in line with the theory of reasoned action as presented by Ajzen and Fishbein (1980), which related to consumers’ belief about and attitudes towards their behavioral intentions, as well as to actual behaviors. 68 In term of measurement, Knox and Walker (2001) explored that attitudinal loyalty was assessed on the basis of responses to the statement by asking the favorite brand name regardless of price. Besides, the measurement of attitudinal loyalty was based on other factors, such as customer’s intention of repeat purchase (Anderson & Sullivan, 1993; Cronin & Taylor, 1992; Chiou & Droge, 2006), recommendation to others (Boulding, Kalra, Staelin & Zeithaml, 1993; Reich, McCleary, Tepanon & Weaver, 2005; Russell-Bennett et al., 2007), low switching to better competitors (Narayandas, 1996), attachment (Back, 2005), or willingness to pay a price premium (Narayandas, 1996; Zeithaml, Berry & Parasuraman, 1996). As a conclusion, attitudinal brand loyalty was considered as an important dimension in the context of hospitality sector (e.g. fast food) as loyalty customers would commit on post-consumption behavior (Kim, Magnini & Singal, 2011). That is, it was referred as the depth and of the psychological bond consumers had with the fast food brands, such as recommendation to other, active engagement sense of community, and positive word-of-mouth (Keller, 2001). 69 2.11 Conclusion A comprehensive literature review was done in this chapter; basically, there were two different perspectives in brand equity conceptualization, which were financial and consumer-based. This study had adopted consumer perspective brand equity with psychological-based approach. There were different dimensions of consumer-based brand equity across industries, in this study; six dimensions were identified, namely perceived quality, brand awareness, brand familiarity, brand image, brand trust and attitudinal brand loyalty. For the purpose of this study, Gil et al.’s (2007) theory was adopted and modified to generate a meaningful research in examining the attitudes of Malaysian fast food consumers. Reason being they had highlighted the causal relationships between dimensions of consumer-based brand equity, which based on the explanation of cognitive-affective-conative. Additional dimensions such as brand familiarity and brand trust were included as they served as important dimensions in the context of fast food. All the variables in this study were considered as a uni-dimensional constructs rather than a multidimensional. This was because the purpose of this study was to develop a new model of consumer-based brand equity rather than to identify dimensionality of the constructs. Subsequently, all of the variables were measured wholly in term of its truth, having no detail breakdown of elements. Each of the constructs was extensively discussed, and the definition for each of the variables was indicated, based on previous researchers’ definition and suitability for this study. Chapter Two would lead to better measurement for the development of instrument in Chapter Three. 70 CHAPTER 3 RESEARCH METHODOLOGY 3.1 Introduction Firstly, this chapter starts with the presentation of research framework, which has extended Gil et al.’s (2007) model. Additionally, each of the hypotheses was elaborated. Next, the chapter is followed by the formation of questionnaire and the selection of instrument items for each of the variables. Basically, there were three studies conducted, namely preliminary study, pilot study and main study. The main objective of the preliminary study was to identify stimulated brands and brand image measurement in the Malaysian context of fast food industry. Therefore, open-ended question was conducted to allow the respondents to freely express brand image by means of their own terms. Subsequently, the design of the pilot study and main study are also presented. The main study was described by a sample selection and data collection procedures. Information about collection procedures for collecting data is also included. The last part of the chapter explains the methods of the data analysis. This section involved the justification for the use of Structural Equation Modeling (SEM). Lastly, the chapter presents the detail of descriptive analysis, assessment the fit of measurement model and assessment the fit of structural model. 71 3.2 Overview of Proposed Research Framework Note: BA=Brand awareness, PQ=Perceived quality, BF=Band familiarity, BI=Brand image, BT=Brand trust, ABL=Attitudinal brand loyalty, BE=Brand equity Figure 3.1: Proposed Research Framework Based on Gil et al.’s (2007) theory of brand equity, a proposed research framework was developed as presented in Figure 3.1. Brand familiarity and brand trust were identified as additional dimensions because they served as important dimensions in the context of fast food (Morgan & Hunt, 1994; Smith, 1993). The research framework postulated that there are causal relationships among dimensions of consumer-based brand equity. It served as an important platform in explaining the missing link between perceived quality and brand equity as indicated in Gil et al.’s (2007) framework. With reference to the above framework, perceived quality might have influenced on brand equity via other variables, for instance brand image, brand trust and attitudinal brand loyalty. 72 Besides, the research framework also had shown that attitudinal brand loyalty played as the key variable in explicating the relationships between other dimensions and overall brand equity. In other words, brand equity did not exist when there was no attitudinal brand loyalty. This proposition corresponded to Gil et al.’s (2007) research framework. In addition, the dimensions of consumer-based brand equity were categorized as cognitive-affective-conative characters. One possible explanation could be that the traditional attitude structure started with cognitive beliefs (perceived quality, brand awareness, brand familiarity and cognitive brand image), followed by affective response (affective brand image and brand trust), and followed by conative responses (attitudinal brand loyalty and overall brand equity) (Ajzen & Fishbein, 1980; Oliver, 1997). As highlighted above, brand image covered a border view of consumers’ response, both cognitive and affective characters. The results from preliminary study (see section 3.4.2 Result of Preliminary Study) supported the view that consumers would have both cognitive and affective image towards the fast food brands. More ever, this findings has been echoed by many studies in environmental psychology which had indicated consumers would have both cognitive and affection images towards a destination (Russel & Pratt, 1980). The element of cognitive was referred to the knowledge that consisted of objective attributes (Keller, 1993). On the other hand, affective component was referred to as the emotional feeling and affective quality (Genereux et al., 1983). As a conclusion, the proposed research framework was in line with Gil et al.’s (2007) theory. However, it had extended their model by including the categorization of cognitive-affective-conative in consumer-based brand equity setting. Furthermore, it covered greater numbers of consumer-based brand equity dimensions and examined greater numbers of causal effects. 73 3.3 Development of Hypotheses According to Erdem and Swait (1998), when there was existence of uncertainty about product attributes, brand could be served as a platform to ensure credibility and position of the product by decreasing perceived risk and information costs as identified by consumers. Therefore, the reduction of uncertainty leads to higher quality as expected by consumers (Erdem & Swait, 1998). Dodds, Monroe and Grewal (1991) indicated that brand awareness or brand popularity had positive effect on consumers’ perception of quality and value. Therefore, brand awareness allowed consumers to associate the brand with its product category, referring to the potency of the brand presented in the consumers’ mind (Aaker, 1996). This could be supported by Grewal, Krishnan, Baker and Borin (1998) bicycle brand study; both perceived quality and brand awareness were positively correlated. As a result, this study concluded that there was positive correlation between perceived quality and brand awareness. On the other hand, Gursoy and McCleary (2004) argued brand familiarity was formed by the acquired information through external sources, for instance word-ofmouth, advertising, and internal sources (such as the use of product). Researchers stressed out that the higher the brand awareness, the greater the brand familiarity and reputation (Cobb-Walgren et al., 1995; D’Souza & Rao, 1995). Researchers also proved that brand awareness was the dominant selection process among consumers (Reynolds & Olson, 1995). This could be supported by Alba and Hutchinson’s (1987) argument, where a consumer’s recognition and recall of a certain brand name would build a sense to familiarity. 74 Referring to Keller (1993), there were three reasons which indicated the importance on brand awareness in consumer decision making. Firstly, it was essential that the brand came to consumers’ mind, when they thought about the product category. Consequently, the high level of brand awareness had established the brand in the consumer’s mind set and eventually influence on consumer decision making (Hoyer & Brown, 1990; Macdonald & Sharp, 2000). Secondly, brand awareness had enhanced the level of consumers to consider or purchase the brand, regardless whether there was any other brand associated with it. Studies indicated that a low level of brand awareness could significantly result in product purchase decisions, particularly when consumers had to make simple rule of decision (Hoyer & Brown, 1990; Petty & Cacioppo, 1986a), for instance fast food. Thirdly, brand awareness insisted that consumers had to have greater association with its brand image, in other words, it served as a vital element in formatting and presenting a strong brand in consumers’ memory (Keller, 1993). This could be further supported by brand awareness generated differences in information processing, and these differences, which were created by brand associations in the consumer’s memory, directly affected brand image (Hoyer & Brown, 1990). Studies had supported these statements with the evidence that brand awareness positively affected brand image in consumer goods product (Angel & Manuel, 2005; Esch, Langner, Schmitt & Geus, 2006). In addition, Aaker (1991) emphasized that the awareness of brand was the beginning of loyalty. If a customer was aware of a certain product or brand, there was a higher possibility that the customer would have a favorable image of the product or brand. Therefore, positive brand image through high brand awareness had increased the likelihood of brand purchase leading to brand loyalty (Keller, 1993). 75 Brand awareness was an important component of brand equity; it referred to the brand salience that existed in consumers’ memory (Aaker, 1996). Recall, recognition, brand dominance, top-of-mind, brand opinion and brand knowledge were the difference levels of brand awareness (Aaker, 1996). According to Aaker (1991), brand awareness contributed brand equity creation that focused on consumers’ memory, referring to brand node, brand popularity, signal of brand trust, and consideration set of the brand (Aaker, 1991). Even though brand awareness was a vital component of brand equity as discussed. There was no causal effect on brand equity or brand loyalty empirically (Rosa & Riquelme, 2008; Tong & Hawley, 2009; Wang et al., 2008). This could be supported by Rosa and Riquelme’s (2008) online study where brand awareness did not show a significant effect on brand equity. They indicated that brand awareness alone could not guarantee the successful of brand equity in sportswear market. Moreover, Wang et al. (2008) advocated brand resonance, which was brand loyalty in term firm perspective (Keller, 2001), did not support the hypothesis of related positively to the extent to which brand awareness was evident in global brand equity model. Conversely, Gil et al. (2007) proved that brand awareness/association had causal effects on brand loyalty in consumer goods. However, there were only two observed variables existed in the variable, and most of the observed variables were deleted to satisfy the statistical result (Gil et al., 2007). At one hand, previous studies concretely had supported that brand awareness lead to better brand familiarity and brand image. On the other hand, brand awareness did not show a consistency of positive effect on brand loyalty and brand equity. Therefore, the following hypotheses were formulated: Hypothesis 1: There is positive correlation between brand awareness and perceived quality Hypothesis 2: The higher the awareness of a brand, the greater the brand familiarity Hypothesis 3: The higher the awareness of a brand, the greater the brand image 76 Researchers suggested that consumers evaluated the brand more positively when they were familiar with the brand and therefore created favorable images for familiar brand (Janiszewski, 1993; Holden & Vanhuele, 1999). Ho and Chong (2003) suggested that the level of brand familiarity and consumption experiences influenced consumers towards brand attributes, and brand attributes. Brand attributes was one of the components of brand image (Keller, 1993). For this reason, consumers individually assessed each descriptive feature of characterized products or services based on familiarity and experience that they had with the brand (Ha & Perks, 2005). Consequently, the higher level of brand familiarity led to the better evaluation of brand attributes, which ultimately contributed to higher level of brand image (Keller, 2003). The above statement could be supported by Zajonc and Markus’ (1982) study; they proposed that brand familiarity caused consumers to have favorable evaluations on a service or brand. When a consumer was confronted with a familiar brand, he or she had felt emotional closeness and confidence and increased the level of consumer experience, thus drove to greater formation process of brand image (Zajonc & Markus, 1982). Campbell and Keller (2003) advocated that increasing brand familiarity through accumulated customer experiences not only created a knowledge structure for the consumer, but also built up consumer confidence about the brand (i.e. positive evaluation), which led to brand trust (Zajonc & Markus, 1982; Sen & Johnson, 1997). These could be further supported by the development of familiarity which leads to higher level of brand trust (Keller, 1998). According to Alba and Hutchinson (1987), brand familiarity could be derived from customers’ experience. In other words, brand experience can be served or used as criteria for brand familiarity. As a result, brand familiarity had significant influenced on brand trust as the trust of the brand could be derived from positive customer experience (Fullerton, 2005; Papadopoulou, Kanellis & Martakos, 2001; Smith & Wheeler, 2002). 77 For these reasons, the following hypotheses were stated: Hypothesis 4: The higher the familiarity of a brand, the greater the brand image Hypothesis 5: The higher the familiarity of a brand, the greater the brand trust According to brand knowledge (Keller, 1993), good evaluation of perceived quality had increased brand association. This was because when there is a good perception of quality, a positive brand image had been created as there were strong, favorable, and unique associations linked to the brand due to greater brand attributes, benefits, and attitudes as perceived by consumers. This could be supported by Kayaman and Arasli’s (2007) study, where tangibility, reliability and empathy (perceived quality in service industry) showed positive effect on brand image in a hotel study. Mohd Rizaimy et al., (2011) showed that perceived quality could be existed when there is positive satisfactory towards the service providers and food quality. Consequently, these would lead to the establishment of bond between consumers and the brand due to the present of trust feeling (Delgado-Ballester & Munuera-Aleman, 2001). This could be supported by the positive quality evaluation increased consumers’ knowledge and perception of the brand (Keller, 1998), which ultimately influenced the level of trust. For these reasons, positive perceived quality would lead to the enhancement of trust as perceived by consumers (Papadopoulou et al., 2001). According to Gil et al. (2007), brand loyalty preceded brand awareness, brand associations and perceived quality. This was because they applied the theory of cognitive-affective-conative, which classified perceived quality as cognitive construct. They also argued that cognitive construct (perceived quality) had influenced affective, and affective response would drive to conative (attitudinal brand loyalty) and led to purchase decision. Consequently, causal effect could be identified (Chiou et al., 2002). 78 On the other hand, Roberts, Morrison, Chandrashekaran and Gordon (2004) had also applied the concept of purchase decision stages to rationalize the causal relationships between perceived quality and loyalty. In this case, they had identified perceived quality as information evaluation stage, which proceeded to purchase decision stage, referring to loyalty. However, the study of Gil et al. (2007) showed that perceived quality was not significantly affecting brand loyalty and brand equity. Furthermore, Tong and Hawley (2009) indicated that perceived quality did not have causal effect on brand equity; they further explained that by just maintaining high quality or awareness of the brand, was not adequate in ensuring the successfulness of a brand in the sportswear industry. As a result, perceived quality alone was not sufficient in securing overall brand equity (Tong & Hawley, 2009). However, attitudinal brand loyalty could serve as precede construct of perceived quality. Thus, this study had derived the following hypotheses: Hypothesis 6: The higher the perceived quality of a brand, the greater the brand image Hypothesis 7: The higher the perceived quality of a brand, the greater the brand trust Hypothesis 8: The higher the perceived quality of a brand, the greater the attitudinal brand loyalty Indeed brand image has a strong dominant factor in the level of consumer trust (Esch et al, 2006). A positive corporate image such as high competence and reliability would lead to higher level of consumer trust (Sichtmann, 2007). In the retail setting, Esch et al. (2006) confirmed that there was a direct impact of brand image on a consumer’s brand trust, and both direct and indirect influences of brand image on current and future purchases. In the website setting, Yoon (2002) argued there was significant influence of corporate image (i.e. brand image) on consumers’ trust. 79 Besides, a financial study had stressed that brand image was one of the fundamental in building a sincere relationship of trust between customer satisfaction and loyalty (Flavián et al., 2006). If customers had favorable images towards a certain brand, this process would exercise a positive influence on the customer’s trust (Esch et al., 2006; Flavián et al., 2006) and eventually reinforced their loyalty (Back, 2005; Kandampully & Suhartanto, 2000; Kandampully & Hu, 2007). Therefore, this study proposed the following hypotheses: Hypothesis 9: The higher the image of a brand, the greater the brand trust Hypothesis 10: The higher the image of a brand, the greater the attitudinal brand loyalty According to Pitta, Franzak and Fowler (2006), in a perfect world, trust was unnecessary, but in the real world, it reduced the perceived risk by decreasing the possibility of incurring a loss. As a result, Rauyruen and Miller (2007) argued that in order to gain loyalty of customers, one must first gain their trust. For this reason, brand trust had been recognized as a prominent variable leading to long-term relationship with customers, which in turn affected brand loyalty in a positive way (Chiou & Droge, 2006; Flavian et al., 2006; Sichtmann, 2007; Matzler et al., 2008). This could be further supported by many studies which proved that there was positive consumers trust on customer loyalty (Morgan & Hunt, 1994; Mayer, Davis & Schoorman, 1995; Harris & Goode, 2004). Furthermore, some researchers indicated that trust could positively affect attitudinal brand loyalty neither directly nor indirectly via mediating variable, such as customer satisfaction (Chiou & Droge, 2006). In addition, brand trust had a substantial impact on consumer behaviors, such as the selection of existing products and word-of-mouth (Sichtmann, 2007), repurchase intention (Esch et al., 2006), and recommendations to others (Lau & Lee, 1999). 80 Furthermore, Aaker (1996) declared that brand trust went beyond consumer’s satisfaction, which was based on the functional performance of the product and its attributes. In conclusion, brand trust was the key variable to maintain continuous relationships with customers, which sequentially led to attitudinal brand loyalty (Matzler et al., 2008). Thus, the following hypothesis was derived: Hypothesis 11: The higher the trust of a brand, the greater the attitudinal brand loyalty Many scholars argued that loyalty was the foundation of brand equity (Aaker & Joachimsthaler, 2000; Clarke, 2001), because loyal consumer would treat a focal brand as primary choice, prolong to buy a product or service of focal brand even the alternative choices were better than the focal brand (Oliver, 1997). Many studies indicated attitudinal brand loyalty had causal effect on brand equity (Gil et al., 2007; Kim & Kim, 2004; Norjaya et al., 2007; Tong & Hawley, 2009; Yoo et al., 2000). This showed the essential role of attitudinal brand loyalty in brand equity creation. This could be further supported by attitudinal brand loyalty such as customer’s intention of repeat purchase (Anderson & Sullivan, 1993; Clarke, 2001; Cronin & Taylor, 1992; Chiou & Droge, 2006), recommendation to others (Boulding et al., 1993; Reich, et al., 2005; Russell-Bennett et al., 2007), low switching to better competitors (Narayandas, 1996), positive word-of-mouth (Clarke, 2001), and brand attachment (Back, 2005). Therefore, the following hypothesis was recommended: Hypothesis 12: The higher the attitudinal loyalty of a brand, the greater the brand equity 81 3.4 Questionnaire Development The purpose of instrument items was to test the twelve formulated research hypotheses. It was important to ensure that the instrument accurately measured the underlying constructs or variables. The majority of the instruments were borrowed from previous studies, which were constructed from other countries and industries. Therefore, it was necessary to test the instruments prior to the data collection process to ensure its applicability in the Malaysian fast food market. Subsequently, brand image instruments were developed through preliminary study as different industry would have different consumers’ response on brand image (Aaker, 1996; Kim & Kim, 2005). A six-point scale (with anchors of 1 = strongly disagree and 6 = strongly agree) was employed to indicate a degree of agreement for each of the items (Hishamuddin, 2007). There are two major parts in the survey form: (1) Evaluation of brand equity, and (2) Demographic questions. 3.4.1 Preliminary Study The main objective of preliminary study was to select fast-food restaurant chains for pilot study and main study. Besides, it also serves as a function in developing brand image measurement. According to Low and Lamb Jr. (2000), the development of brand image scale was designed to be product-specific. Chowdhury, Reardon, and Srivastava (1998) also stated that a free response technique needed to be applied in brand image studies. Therefore, open-ended question was proposed as it allowed for gathering consumers’ point of view, feelings and any perspective that related to the issues (Lindlof & Taylor, 2002). 82 In order to explore brand image associations from the consumer’s selfexplicated perceptions, a free response technique was adopted for this study, rather than answers to definitional questions provided by the researcher (Park, 2009). This was because it allowed respondents to freely express a given motivation by means of their own terms (Jain & Etgar, 1976-1977). During preliminary study, two open-ended questions were addressed; the second question was adopted from previous studies (Zimmer & Golden, 1988; Keller, 2003). Two questions were illustrated below: Questions 1: Please list three fast food restaurant chains in which you had most frequently dined. Questions 2: You can freely describe any characteristics that come to mind when you think about … (above brand(s) name)… using any words/phrases your choice. According to Zimmer and Golden (1988), respondents would express greater cognitive attribute-related descriptions as compared to affective type, even affective descriptions present in the consumer’s mind. Since open-ended question was used, the study was not restricted to any type of answer (cognitive or affective) being provided by consumers, it covered different type of brand image as associated by consumers. The preliminary study consisted of 45 consumers, which had been conducted from 20th November 2010 to 28th November 2010, as presented in Table 3.1 Table 3.1 Time Slot of Preliminary Study 11 a.m. 12 p.m. 2 p.m. 4 p.m. 6 p.m. Total Respondents 20Nov 1 1 1 1 1 21Nov 1 1 1 1 1 22Nov 1 1 1 1 1 23Nov 1 1 1 1 1 24Nov 1 1 1 1 1 25Nov 1 1 1 1 1 26Nov 1 1 1 1 1 27Nov 1 1 1 1 1 28Nov 1 1 1 1 1 5 5 5 5 5 5 5 5 5 83 3.4.2 Result of Preliminary Study At the beginning of the research, the respondents were informed of the objective of the study and were requested to list down three fast food restaurant chains that they had most frequently visited. The result showed that the most popular fast food brands were McDonald’s, Kentucky Fried Chicken (KFC), Pizza Hut, A&W, Burger King, Marrybrown, 1901 Hot Dogs, Domino Pizza, and Subway as indicated in Table 3.1 Table 3.2 Identified Fast Food Brands Fast Food Brands Number of Hits McDonald’s 44 Kentucky Fried Chicken (KFC) 39 Pizza Hut 27 A&W 4 Burger King 4 Marrybrown 4 1901 Hot Dogs 4 Domino Pizza 3 Subway 2 Papa John’s 1 Carl’s Jr. 1 Nando’s 1 Rasamas 1 In order to identify the brand image of fast food, the second open-ended question was asked. There was no right or wrong answer; respondents were free to express their answer based on the selected brands in question 1. 84 Table 3.3 Identified Brand Image Items Brand Image Instruments Number of Hits Delicious 33 Easy and fast 25 Good physical environment 17 Pleasure 14 Free WiFi 13 Good customer service 11 A place for gathering 10 Many types of choices 8 Free refill 7 Convenience 7 Widely distributed 4 Initially, there were 46 items had been identified from the preliminary study (see Appendix A). However, only 11 items were selected as the numbers of hits were more than 1 time (see Table 3.3). Consequently, 35 items were excluded. One additional item, “Long history” was added to the brand image measurement, based on previous studies on brand image (Aaker, 1991; Keller, 1993; Kim & Kim, 2005). Thus, there were 12 initial observed variables of brand image that was created to enhance the consumers’ understanding about the measurement. 85 3.4.3 Selection of Fast Food Brands In this study, fast food brand was defined as those restaurant corporations that provided expedited food service, established standard operating procedure (SOP), offered Western pattern diet, and had franchises in multiple states or nationwide (Ashkanasy & Nicholson, 2003; Block et al., 2004; Burdette & Whitaker, 2004; Slattery et al., 1998). Initially, the study tried to approach all the thirteen fast food head offices to participate in this study (see Table 3.1). First and foremost, phone calls were made to invite those companies to participate. Next, it was followed up with an electronic official letter on the university’s letter head to further support the application. The study later confirmed that the data gathered would be reserved for research purpose only. Nevertheless, only Marrybrown and 1901 Hot Dogs were willing to give permission to conduct survey in their restaurants. Both of the companies were very cooperative and helpful. The person-in-charge (PIC) provided verbal consent to conduct research fieldwork at their outlets. However, the PIC reminded the researcher to ensure that data collection process did not interrupt their daily operations and customer service. The managers of other fast food brands with head offices located in Kuala Lumpur did not allow third parties to conduct any surveys on their products and services because they did not want any interruptions in business operations. Importantly, they had to get permission from their franchisees and had accounted for all the consequences of this survey. However, their advice was to approach the supervisors of targeted outlets informally. Eventually, verbal permission was obtained from the branch supervisors of McDonald’s, Kentucky Fried Chicken, and Pizza Hut. 86 According to Bernama (2009), Malaysian brands enjoyed popularity from overseas, which included food products such as Secret Recipe, 1901 hotdogs, and Marrybrown. These could be supported in year 2010, Business Times (2010) reported Marrybrown Fried Chicken private limited had successfully expanded Malaysian foodservice franchise to 10 other countries, and 1901 Hot Dogs currently had expanded their business to Singapore and Indonesia with eight outlets. On the other hand, there were 475 KFC outlets, 194 McDonald’s outlets (Hoe, 2009), and 193 Pizza Hut outlets (MIDF Research, 2009) in Malaysia. According to Aseambankers (2007), they controlled approximately 80% fast food market share in Malaysia. As a result, the selected fast food brands (1901 Hot Dogs, Marrybrown, McDonald’s, KFC, and Pizza Hut) represented relevant and reliable brands which finalized in this study. 3.5 Operational Definitions and Development of Measurement Scales As mentioned in Chapter 2, there were seven variables which had been identified in this study, such as perceived quality, brand awareness, brand familiarity, brand trust, brand image, attitudinal brand loyalty and brand equity. The measurement scales for each of the variables were derived from the previous authors, except for brand image. Next section discusses the measurement items for each of the variables. 3.5.1 Perceived Quality Instruments In the service industry, Kim and Kim (2005) indicated that perceived quality could be classified into two types. Firstly, it was referred to as the service quality that was provided by physical facilities, such as business hours, physical environment, and modern equipment. Secondly, it was referred to service quality provided by employees, such as courtesy, responsiveness, and helpfulness. Both of these perceived quality evaluations had cognitive responses at the attribute level (Chiou et al., 2002). The current study defines perceived quality as the overall customers’ cognitive response on the superiority of service quality when offered by companies and employee. 87 In this study, performance-based approach was selected to measure perceived quality, rather than expectation and perception approach (Olorunniwo, Hsu, & Udo, 2006). This was because the focus of this study was to identify the perception of consumers towards the brands instead of examining consumers’ expectation (Olorunniwo et al. 2006). Therefore, the measurement scheme was adopted from SERVPERF, also well-known as SERVQUAL’s approach (Fick & Ritchie, 1991; Lee & Hing, 1995; Parasuraman, Zeithaml & Berry, 1985). There were number of components that had been classified under SERVQUAL, in order to measure unidimensional of perceived quality, this study implemented ten items of SERVQUAL as recommended by Kim and Kim (2005, p.559) in their fast food chains study. 3.5.2 Brand Awareness Instruments Brand awareness was defined as the potentiality of consumer to identify a particular brand from his or her memory when encountering a selection process or decision making progress. Three items were developed from previous studies (Park, 2009, p.56), another item: “When I think about [fast food category], X is the first brand that comes to my mind” was adopted from the study by Gil et al. (2007, p.193). 3.5.3 Brand Familiarity Instruments This study characterized brand familiarity as well-established through cognitive representations of knowledge stored in memory with the brand, as consumers became familiar with the brand; they were more likely to perceive the brands’ relevance. Subsequently, three items were adopted from previous research studies (Park, 2009, p.57). One additional item was added: “I do not know about X”. 88 3.5.4 Brand Image Instruments Brand image was considered as a uni-dimensional construct rather than a multidimensional as the purpose of this study was to develop a new model of consumerbased brand equity, rather than to identify the dimensionality of brand image. Thus, this study defined brand image as overall image that was formed from the result of both cognitive and affective images towards fast food brands. The element of cognitive was referred to as the knowledge that consisted of objective attributes. On the other hand, affective component was referred to as the emotional feeling and affective quality (Genereux et al., 1983). Low and Lamb Jr. (2000) stated the development of brand image scale should be designed according to product-specific. A total of 11 items had been identified from preliminary study (see Table 3.3 Identified Brand Image Items). Besides, this study also had adopted one additional item “Long history” from Kim and Kim’s (2005, p.559) measurement due to its common use in fast food studies. 3.5.5 Brand Trust Instruments Brand trust was operationally defined as the affective component of attitude towards a brand, such as feelings held by an individual that was based on psychological perceptive. Brand trust was measured by four items that was adopted from Matzler et al. (2008, p.156) and Park (2009, p.57). 3.5.6 Attitudinal Brand Loyalty Instruments Attitudinal brand loyalty was defined as the propensity to be loyal to a focal brand as presented by the brand choice, brand intention and brand commitment. Four items were adapted from Chiou and Droge (2006, p.625) to measure brand attitudinal brand loyalty. 89 3.5.7 Brand Equity Instruments Consumer-based brand equity was operationally defined as the brand commitment that resulted from consumer’s perception of overall superiority of a particular product or service category carrying that brand name. Brand equity was measured using four items from Gil et al. (2007, p.193). Table 3.4 Instrument Items Instrument Items Authors Perceived quality The staff gives customers individual attention.

I consider myself to be a loyal customer of X. This brand is special to me. Brand Equity It makes sense to visit X instead of any other brand, even if they are the same. If there is another [fast food category] brand as delicious as X , I prefer to visit X. X is definitely my choice in [fast food category]. Even if another [fast food category] brand has the same price as X, I would still visit X. 91 Chiou and Droge (2006, p.625) Gil et al. (2007, p.193) 3.6 Pilot Study A pilot study was conducted to assess the clarity of the questions, as well as the reliability and validity of the measurement items (Hishamuddin, 2007). Initially, the study tried to include the validity test for both academicians and practitioners. It was followed up with an electronic official letter on the university’s letter head to further support the request. Nevertheless, only academicians were willing to give suggestion for the improvement of questionnaire. Eventually, the validity of the questionnaire was determined by Associate Professor Dr. Norjaya Mohd. Yasin (Universiti Kebangsaan Malaysia), Professor Dr. Kim Hong-Bumm (Sejong University, Seoul, Korea), and Mr. Lai Kim Piew (Multimedia University, Melaka campus, Malaysia), three of them are academicians, who are experts in the area of branding research studies. Firstly, “The staff is knowledgably and confidence”, the perceived quality instrument was split into two separate observed variables to avoid double barrel questions. Thus, the item was split into two items: “The staff of X are knowledgeable” and “The staff of X are confident”. Besides, “Free refill”, a brand image instrument was replaced to “Good value for money”, “Fast and easy” was suggested to be expressed into two different items, which were “Fast” and “Prompt service” respectively. There were only minor amendments recommended by the experts, most of the suggestions were related to the structure of the statements and English proficiency. The feedback from branding experts served as an important source for the validation of question. A total number of 50 surveys were collected from a nonprobability convenience sampling from fast food consumers. The questionnaires were distributed to consumers who had dined-in the fast food restaurants; they would then return the completed survey to the researcher. Upon receiving the survey form from respondents, they were asked if they had any doubts or difficulties in answering the questions (Yoo et al., 2000). The respondents were asked to present their suggestions or to provide ideas to improve the questionnaire. 92 Thus, adjustments to the items were made only after the consultation from the experts. The Cronbach’s alpha, Skewness and Kurtosis test were used to analyze the reliability of measurement items, and any items that were found to be unreliable were dropped. According to Nunnally (1978), Cronbach’s alpha between 0.50 and 0.60 was acceptable for pilot study. Referring to result in Table 3.5, the range for Cronbach’s Alpha was from 0.75 to 0.91, which satisfied the cut-off value as suggested, indicated internal consistency for the constructs. Besides, Skewness and kurtosis were used to determine the test for normality, and a common rule-of-thumb for normal distribution data was the observed variables should be ranged within absolute value of 2 (Tong, 2006). The result indicated that the values of skewness and kurtosis for all the observed variables (except BA3) were within absolute value of 2. Higher kurtosis meant that more of the variance resulted of infrequent extreme deviations, as opposed to frequent modestly sized deviations (Mbogdan, 2010). Since there were only 50 respondents, it had not provided sufficient evidence to conclude the findings for BA3; it might be due to lack of power (Hair, Black, Babin & Anderson, 2010). Thus, this study concluded that the data was normally distributed and all of the listed instruments be used for the main study. Lastly, the results of the pilot study also confirmed that the construct reliability of brand image, were derived from the preliminary study. This was because the items of the brand image were normally distributed and Cronbach’s Alpha (α = 0.84) was above cut-off value. 93 Table 3.5 Results of Mean, Normality and Reliability for Pilot Study Instrument Items Mean Skewness Kurtosis Brand awareness (α = 0.75) BA1 I am aware of X. 5.48 -0.95 -0.24 BA2 X is highly recognized. 5.66 -1.58 1.54 BA3 I have heard a lot about X. 5.34 -2.29 8.06 BA4 When I think about [fast food category], X is the first brand that comes to my mind. 5.32 -1.27 1.07 4.17 -0.14 -0.66 4.79 -0.51 0.55 4.43 0.07 -0.66 4.11 -1.12 2.14 4.34 0.06 -0.23 4.17 0.34 -0.41 The staff of X are confident.

Note: α = Cronbach’s Alpha 96 3.7 Sample Size and Data Selection This study targeted fast food consumers in the respective restaurants. This was because they were easy to be accessed when customers dined-in at fast food restaurants. The sample size comprised of consumers’ age range from 18 to 45 years old. Five fast food restaurants from different area of Klang Valley were selected for this study. With respect to sample selection, Peninsular Malaysia was selected because most of the fast food outlets were based in Peninsular Malaysia than in East Malaysia, while it was also impracticable to study the whole of Malaysia because of budget and time constraints (Saunders, Lewis & Thornhill, 2003). According to Norzalita and Norjaya (2010), Klang Valley was considered as the most highly populated region in Malaysia, which consisted of people from diverse ethnic compositions and demographic groups, such as people from different states of Malaysia. In addition, Klang Valley was located within the Federal Territory of Malaysia, populated with economically and socially most advances people (Norzalita & Norjaya, 2010). Furthermore, it composed of approximately 25% population in Malaysia (Horlic, 2011). For these reason, Klang Valley are widely selected for Malaysian research (Chan, 2009; Chok, 2008; Hee, 2009; Hishamuddin, 2007; Norjaya et al., 2007; Norzalita & Norjaya, 2010; Ooi, 2009; Siti Safira, 2008; Yap, 2009). The main reason of using nonprobability sampling was because the use of random sampling was not possible in fast food study. Importantly, the number of fast food consumers could not be identified as there was no statistical support data. Everyone in this world could become fast food consumers, thus it would lead to the inaccuracy of sampling frame if probability sampling was proposed. Furthermore, the conceptual model of this study was derived from theoretical generalizability, not population generalizability (Calder, Philips & Tybout, 1982). For these reasons, nonprobability sampling method had been selected. 97 Therefore, non-probability convenience sampling method was adopted as it was efficient and appropriate (Cavana, Delahaye & Sekaran, 2000). In addition, this method was used in most of the brand equity or fast food studies (Bamert & Wehrli, 2005; Chan, 2009; Gil et al., 2007; Henry et al., 2010; Kayaman & Arasli, 2007; Kim & Kim 2004, 2005; Kobayashi, 2011; Lin, Marshall & Dawson, 2009; Namkung & Jang, 2010; Pike et al., 2010; Mohd Rizaimy, Abdul Sabur, Suhardi, Shamsul, Muna & Maznah, 2011; Mohd Rizaimy et al., 2011; Rosa & Riquelme, 2008; Ryu, Han & Jang, 2010; Tong & Hawley, 2009; Henry et al., 2010; Wang et al., 2008; Van Zyl et al., 2010; Yoo et al., 2000; Zainuddin, Kamaruzaman, Muhammad Abi, and Wan Asri, 2009). Those consumers who had agreed to participate were given self-administrated questionnaire, where respondents were instructed to complete the questionnaire and return the survey to the administrator in the respective restaurants. With reference to Table 3.6, a total number of 600 questionnaires were distributed because this study was in line with nonprobability sampling of previous studies (Halim & Hamed, 2005; Perez, Padgett & Burgers, 2011; Yoo et al., 2000), and the sample size was adequately above the number of nonprobability convenience sampling for most of the recent studies that focused on brand equity or fast food research (see Table 3.6). According to Loehlin (1992), structural equation modeling (SEM) required at least 100 sample sizes, with 200 being better. On the other hand, Stevens (1996) stated that a good rule of thumb was at least 15 cases were needed for every predictor in a standard ordinary least squares multiple regression analysis. There were 6 predictors; therefore 90 observations met the minimum sample size for the SEM analysis as defined in the multiple regression. However, Hair et al. (2010) stated that the proposed guidelines varied with analysis procedures and model characteristics. Thus, they further highlighted that five considerations affecting the required sample size for SEM to include multivariate normality of the data, estimation technique, model complexity, amount of missing data, and average error variance among the reflective indicators. 98 Table 3.6 Sample Size of Previous Research Author(s) and Year Lassar et al.

(2011) Kobayashi (2011) 100 325 120 120 To summarize, sample size could be determined by looking at the number of constructs (Hair et al., 2010), predictors (Stevens, 1996), parameter estimates (Benter & Chou, 1987). There were seven constructs to be examined in SEM, thus the minimum sample size was 150, where provided the modest communalities which were greater than 0.50 and with no under-identified (fewer than three observed variables) constructs (Hair et al., 2010). Therefore, sample size of 600 was statistically sufficient. 3.8 Data Collection Procedures According to Yoo et al. (2000), if respondents had known and experienced the brand well, they would have been able to provide reliable and valid responses to the questionnaire. Thus, respondents were selected individually or in group conveniently from fast food restaurants that were willing to complete a self-administrated questionnaire inside or outside these restaurants. Table 3.7 showed the sampling design for 600 questionnaires that accomplished from the shopping complexes in the area of Klang Valley, Malaysia. The main reason was to reduce the potential bias and increase the precision of estimates for non-probability sampling (Chang & Chieng, 2006).

The schedule was planned according to the locations as agreed by the person-in-charge of fast food brands. Table 3.8 had presented the summary of data collection as extracted from Appendix B, which indicated the numbers of questionnaires that collected from Monday to Sunday.

During the briefing, the instruments items and objectives of conducting the research were discussed. Survey administrators were given chances to ask any unclear statements used as instruments in the questionnaire. Survey administrators had the responsibility to explain the research objective, meaning of the questionnaire, the words and the exact meaning to individual respondents. To avoid the same respondents being selected more than once, the survey administrators must ask respondents whether they had completed the survey at a prior time. If the respondents had completed the survey before or declined to do the questionnaire, then the next eligible respondents were selected. In the beginning of the questionnaire, a written statement “there are no right or wrong answers; only your personal opinions matter” was included for minimizing possible response bias (Aronson et al., 1990). All the instrument items were assessed via the respondents’ perceptual evaluations and recall of their experiences. 102 3.9 Method of Data Analysis Structural Equation Modeling (SEM), a statistical methodology with a confirmatory approach was selected to analyze multivariate data. This was because SEM was frequently and widely used technique in psychology and social sciences research (Bentler, 1983; Browne, 1984; Hair et al., 2010; Schumacker & Lomax, 2004). According to Hair et al. (2010), SEM was the most appropriate and efficient estimation technique for estimating a series of separates multiple regression equations simultaneously, and provided evidence of systematic covariation that demonstrated causal relationship was not spurious. Thus, SEM is often referred to as causal modeling (Hair et al. 2010). As a result, this method is widely used among the recent study in branding which investigated the causal effects (see Bergkvist, & Bech-Larsen, 2010; Biedenbach, & Marell, 2010; Carroll & Ahuvia, 2006; Chang & Chieng, 2006 ; Da 9 Silva & Sharifah, 2006; Gil et al., 2007; Hess, & Story, 2005; Malär et al. 2011; Martin & Stewart, 2001; Park et al., 2010; Thomson, MacInnis & Park, 2005; Tolba, & Hassan, 2009). Exploratory factor analysis (EFA) was not recommended to be performed as this study had identified the numbers of composite dimensions (Hair, et al., 2010). That is, it required the confirmation process of pre-specified observed variables in representing a particular construct instead of data summarization. Thus, confirmatory factor analysis (CFA) was recommended rather than EFA (Hair, et al., 2010). Firstly, CFA was performed to identify the measurement model, which to confirm the relationship between the observed variables and latent variables. Bentler (1983) further highlighted that it also enabled a comprehensive assessment of construct validity, which included convergent and discriminant validity. Secondly, the structural model was conducted to estimate the causal relationships between the latent variables, and tested the hypotheses in a path diagram. Byrne (2010) stated that it indicated a direct and indirect influence between particular latent variables and other latent variables in the model. In this study, statistical software SPSS 16.0 and AMOS 16.0 were used and the data analysis were conducted using a three steps approach, namely descriptive analysis, assessment the fit of measurement model and assessment the fit of structural model. 103 3.9.1 Descriptive Analysis The sample characteristics of respondents and the observed variables were first presented, which included mean, frequencies, percentages, and standard deviations. 3.9.2 Assessment the Fit of Measurement Model According to Hair et al. (2010), standardized loading estimate for each of the item should be 0.5 or higher, and ideally 0.70 to ensure validity of the constructs. In general, there were potentially of unacceptable degree of error that might call for the omission of an observed variable if the standardized residuals for any pair of the items were greater than absolute value of 4.0, however, absolute value between 2.5 and 4.0 deserved for attention (Hair, et al. 2010). This would be further followed by factor cross-loading that was based on modification indices (Byrne, 2010). Next, a measurement of the internal consistency of the construct, construct reliability was taken into consideration, with a minimum criterion of 0.70 (Hair et al. 2010). A confirmatory factor analysis was conducted to measure the adequacy of the measurement model. Gerbing and Anderson (1988) highlighted the importance of unidimensionality in the scale development process. They further argued that the traditional exploratory analyses (e.g., item-total correlation and factor analysis) were not theory based analysis and hence they failed to assess uni-dimensionality directly. To overcome this limitation, confirmatory factor analysis (CFA) was employed for the assessment of measurement model fit and uni-dimensionality (Hair, et al., 2010). Convergent validity was determined by standardized factor loading, t value, and average variance extracted (AVE) (Hair, et al., 2010). The cut-off value of AVE for each of the constructs was 0.50 thresholds (Fornell & Larcker, 1981). 104 Discriminant validity was conducted to test whether the two constructs were statistically different (Hair et al. 2010). According to Fornell and Larcker (1981), discriminant validity was determined by the variance extracted value, whether or not it exceeded the squared inter-construct correlations associated with that construct. Besides, Nomological validity was tested to examine whether the correlations among the constructs in a measurement theory made sense (Hair et. al, 2010). The overall model fit for both measurement and structural models were evaluated using conventional fit indices, which included Chi-Square/df ratio, Root Mean-Square Error of Approximation (RMSEA), Standardized Root Mean Square Residual (SRMR), Goodness of Fit (GFI), Comparative Fit Index (CFI), Normed Fix Index (NFI), Incremental Fit Index (IFI), and Tucker-Lewis Index (TLI) (Hair et al., 2010). 3.9.3 Assessment the Fit of Structural Model The structural model was used to estimate parameters and test hypotheses (Hair et al., 2010). First, the specification of the structural model was conducted, followed by the validity assessment of structural model, which included the comparison of standardized factor loadings and construct reliability for both proposed structural and final measurement models. Next, Goodness-of-Fit statistics and the examination of structural model diagnostics were monitored before testing the hypotheses. The structural relationships (causal effect) were represented by single headed straight arrows. All the structural relationships were specified according to the established hypotheses. Hypotheses were assessed by determining the significance level, t value, and standardized coefficient (β), which is similarly addressed as standardized parameter estimates. In addition to that, the unstandardized parameter estimates (b), standard error (se) and confidence interval (CI) were highlighted to explain the 95% confidence interval for the range of b. Models re-specification was conducted to investigate the contribution of proposed model to the existing models of consumer-based brand equity. For instance, the proposed model was compared with Aaker’s (1991) and Gil et al.’s (2007) model, which included Goodness-of-fit index, structural parameter estimates, and squared multiple correlations. 105 3.10 Relevancy of the Research Framework In order to ensure the relevancy of the research framework to research objectives as discussion in section 1.5, the following explanation was listed. Note: BA=Brand awareness, PQ=Perceived quality, BF=Band familiarity, BI=Brand image, BT=Brand trust, ABL=Attitudinal brand loyalty, BE=Brand equity Figure 3.2: Relevancy of Research Framework and Research Objectives Remarks: Research Objectives (page 15 to 17) RO 1: To examine brand familiarity as the additional dimension of consumer-based brand equity in the Malaysian context of fast food industry RO 2: To examine brand trust as the additional dimension of consumer-based brand equity in the Malaysian context of fast food industry RO 3: To investigate the causal relationships among dimensions of consumer-based brand equity in the Malaysian context of fast food industry RO 4: To develop consumer-based brand equity model in the Malaysian context of fast food industry 106 3.11 Conclusion A total of twelve hypotheses had been proposed in this study. The stimulated brands were McDonald’s, KFC, Pizza Hut, Marrybrown, and 1901 Hot Dogs. This was because this study received permission to conduct research in their restaurants. Furthermore, the selected brands controlled approximately 80% fast food market share in Malaysia. Basically, the format of questionnaire were categorized into two parts; evaluation of brand equity and demographic questions. Initially, a total of forty-two items, 6-point scale were proposed. All of the instrument items were adopted from previous studies except brand image. The validity of the question was determined by academicians who are expert in branding study. There were only minor amendments, which had been recommended by the experts, most of the suggestions were related to English proficiency and structure of statements, such as double barrel questions. Fifty pilot surveys were collected from fast food consumers for the validation of survey answer. The results of pilot study indicated that a total of forty-five instrument items were proposed to be used in main study. Nonprobability convenience sampling was suggested in this study. A total number of 600 self-administrated questionnaires were proposed to be distributed in the fast food restaurants from different area of Klang Valley. Structural Equation Modeling (SEM) was selected for the data analysis. There were three steps in the approach for data analysis, namely descriptive analysis, assessment the fit of measurement model and assessment the fit of structural model. As a conclusion, chapter three had presented a clear picture and fundamental idea of the research methodology, which serves as an important platform for data analysis in chapter four. 107 CHAPTER 4 DATA ANALYSIS 4.1 Introduction The main objective of this chapter is to present the results from the main study. Basically, there are four distinctive parts of this chapter, descriptive analysis, assessment the fit of measurement model, assessment the fit of structural model, and model re-specification. Descriptive analysis included sample descriptions such as the frequency and percentage for respondents’ gender, ethnic group, age, occupation, income group, and average fast food spending. Next, analyzes of constructs were conducted for each of the observed variable. Assessments the fit of measurement model included the investigation of Goodness-of-Fit (GOF) statistics, model identification, construct reliability, convergent validity, discriminant validity, and nomological validity. Assessments the fit of structural model consisted of model specification, structural model identification, recursive model justification, model validity, GOF statistics, model diagnostics, and finally the results of the structural parameter estimates, referring to hypotheses testing (Hair et al, 2010). Finally, model re-specification was examined, referring to the comparison of different concepts between the proposed model and Aaker (1991), as well as with Gil et al. (2007). 108 4.2 Sample Descriptions A total number of 600 questionnaires were distributed in the Malaysian (Marrybrown and 1901 Hotdogs) and foreign (McDonald’s, KFC and Pizza Hut) fast food brand restaurants. The study was collected from a nonprobability sample from 1st April 2011 to 1st May 2011 in the following locations of Klang Valley: a) Suria KLCC b) Mid Valley Megamall c) Berjaya Times Square Shopping Mall d) Jusco Metro Prima Shopping Centre e) Pavilion KL f) Sungei Wang Plaza After the data screening process, 15 surveys were excluded due to incomplete responses. Thus, 585 or 97.50% of respondents were qualified and used for further analysis. Out of the pool of completed survey forms, 49.74% were Malaysian brands and 50.26% were foreign brands as indicated in Table 4.1. Only two Malaysian fast food brands were selected (as discussed in Chapter 3), however, the total number of survey forms between Malaysian and foreign brands did not notably vary, which were 291 and 294 respectively. Table 4.1 Fast Food Brands Fast Food Brands Frequency Percentage Marrybrown (Malaysian) 144 24.62 1901 hotdogs (Malaysian) 147 25.13 KFC (Foreign) 94 16.07 McDonald’s (Foreign) 100 17.09 Pizza Hut (Foreign) 100 17.09 109 4.2.1 The Respondents’ Background As shown in the Table 4.2, the respondents of this study were 50.43% male and 49.57% female, which were almost equally distributed. With respect to ethnic group, 63.09% were Malays, followed by Chinese (26.15%), Indian (4.96%), and others (5.80%). The breakdown of the sample in term of gender and ethnic group were considered representative of the population of Malaysia (Index mundi, 2011; U.S. State Department, 2010). Even though the conceptual model of this study was derived by theoretical generalizability, and not population generalizability, but it served as additional credit for this study, for instance to reduce the possibility of selection bias, which produced conducive to statistical analysis in representing the true picture of the population in Malaysia. Table 4.2 Respondents’ Gender Gender Frequency Percentage Male 295 50.43 Female 290 49.57 Table 4.3 Respondents’ Ethnic Group Ethnic Group Frequency Percentage Malay 369 63.09 Chinese 153 26.15 Indian 29 4.96 Others 34 5.80 In this study, some of the descriptions were not completed as the respondents did not signify the information. Thus, they were indicated as missing data and were not reported as part of the percentage (Example: Table 4.4 to Table 4.7). 110 The sample comprised of a high proportion of respondents above 20 years old (78.94%), with a total number of 461. However, further analysis indicated that age 35 and below dominated 82.36% of the survey, the main reason for the high proposition in the sample was probably due to high numbers of Malaysian fast food consumers are from this range. 334 were come from workforce, such as entrepreneur, manager, researcher, engineer, clerk, executive, teachers, technician, chef, designer, consultant, accountant, banker, promoter, lawyer, doctor, artist, designer, webmaster, freelance or social worker and so on. On the other hand, there were 154 students, 5 housewives and 1 retired. This could be further explained that most of the fast food breakfast and lunch promotions nowadays were targeted on workforce and students market. Referring to Table 4.5, it was hardly to obtain retired person and housewife from the sample; obviously, they were not the core target groups for fast food entrepreneurs. Furthermore, the target market of fast food business no longer focused on children and adolescence, they were moving to other consumer segmentation such as college students and workforces. Table 4.4 Respondents’ Age Group Age Group Frequency Percentage 20 years old or less 123 21.06 21- 25 years old 162 27.74 26 – 30 years old 106 18.15 31 – 35 years old 90 15.41 36 – 40 years old 59 10.10 Above 40 years old 44 7.54 * Note: 1missing data 111 Table 4.5 Respondents’ Occupation Occupation Frequency Percentage 154 31.17 Housewife 5 1.01 Own Business 12 2.43 Retired 1 0.20 106 21.46 124 25.10 79 16.00 13 2.63 Student Professional/Managerial Position Executive/Technician/Supervisor/Planner/ Teacher Clerk/Junior Officer/Driver/Security/Promoter Artist/Designer/Webmaster/Freelance/ Social Worker * Note: 91missing data Table 4.6 Respondents’ Income Group Income Group Frequency Percentage Below RM 1,500 205 37.89 RM 1,500 - RM 2,499 106 19.59 RM 2,500 - RM 3,499 98 18.11 RM 3,500 - RM 4,499 59 10.91 RM 4,500 - RM 5,999 27 5.00 Above RM 6,000 46 8.50 * Note: 44 missing data In terms of monthly income of the respondents, 37.89% and 19.59% of the respondents were in the income category of below RM 1,500 and RM 1,500 to RM 2,499 respectively. Surprisingly, in Malaysia, the level of income did not closely relate to the profession. This was supported by where 4 managers’ income was below RM 1,500, 7 managers, 3 teachers/lecturers, and 3 consultants’ income were in the range between RM 1,500 to RM 2,499. 112 Besides, there were 12 managers, 5 engineers, 7 teachers/lecturers, 5 consultants, 7 accountants, and 4 bankers earned within RM 2,500 to RM 3,499. Consequently, only 24.41% of the respondents’ income did exceed the threshold of RM 3,500 even though there was high percentage of workforce samples (67.62%) as indicated in Table 4.5. In addition to that, cross tabulation analysis indicated only 46 out of 132 respondents who earn higher than RM 3,500 (i.e., above 35 years old). On the other hand, there were 51 respondents had monthly income less than RM 3,500 with above 35 years old. Thus, there was no strong evidence to support such findings due to the predominantly younger aged respondents who were still in the early stage of their career path. Table 4.7 Respondents’ Average Fast Food Spending Group Average Fast Food Spending Group Frequency Percentage Below RM 10 27 5.30 RM 10 - RM 19.90 185 36.27 RM 20 - RM 29.90 122 23.92 RM 30 - RM 39.90 55 10.78 RM 40 - RM 49.90 10 1.96 RM 50 - RM 59.90 59 11.57 Above RM 60 52 10.20 * Note: 75 missing data Turning to Table 4.7, more than 40% of respondents agreed that they had spent less than RM 20.00 on average visit in fast food restaurants. The result had corresponded to the price setting of fast food brands; McDonald’s, Marrybrown, and 1901 Hot Dogs were considered the most affordable among students and young adults as the set meals were below RM20.00. Alternatively, Pizza Hut was showed as the highest price among other fast food brands, this was because most of the Malaysia consumers would visit Pizza Hut outlets with their family members or friends instead 113 of individual. Furthermore, Pizza Hut was apprehended where customers were charged 10% extra as service charge for dine-ins, which inflated the final price. 4.2.2 Descriptive Analysis of the Variables This section focused on the descriptive analysis of all the variables in this study. As illustrated in the research framework, the exogenous variables were perceived quality and brand awareness; endogenous variables were brand familiarity, brand image, brand trust, attitudinal brand loyalty, and brand equity. Firstly, the overall constructs were identified. Next, the analysis for each of the variables was specified into observed variables. Table 4.8 Descriptive Analysis (Constructs) Mean Standard Deviation Brand awareness 4.42 1.10 Perceived quality 4.35 0.85 Brand image 4.43 0.80 Brand familiarity 4.42 1.09 Brand trust 4.30 1.07 Attitudinal brand loyalty 4.00 1.11 Brand equity 3.95 1.20 Scale Items of Overall Constructs All the observed variables were measured by a 6-point scale ranging from 1 (strongly disagree) to 6 (strongly agree). Thus, cut-off point of 3.5 [(3+4)/2] was assigned to indicated the difference between disagree and agree opinions for each of statements (Hishamuddin, 2007). The average score for each of the constructs were presented in Table 4.8. The highest mean score was brand image (4.43), which was slightly above brand awareness (4.42) and brand familiarity (4.42). The lowest constructs were brand equity and attitudinal brand loyalty, 3.95 and 4.00 respectively. 114 The result advocated the logicality of brand equity theory; both brand equity and attitudinal brand loyalty were more complicated to be achieved as compared to brand image, brand awareness and brand familiarity (Aaker, 1991). Thus, brand equity and attitudinal brand loyalty were expected to have lower scores. Table 4.9 Descriptive Analysis (Brand Awareness) Scale Items of Brand Awareness Mean Standard Deviation BA1 I am aware of X. 4.72 1.22 BA2 X is highly recognized. 4.60 1.20 BA3 I have heard a lot about X. 4.32 1.36 BA4 When I think about [fast food category], X is the first brand that comes to my mind. 4.06 1.56 Table 4.9 listed the observed variables of brand awareness. The item with the highest score was BA1 “I am aware of X” with the mean score of 4.72. From statements BA1 to BA3, which indicated the level of recognition and exposure towards the fast food brands, BA4 “When I think about [fast food category], X is the first brand that comes to my mind” was related to the consumers’ top-of-mind for a particular product category (Aaker, 1996). In other words, top-of mind was referred to the first brand that automatically appeared on our mind while mentioning a product category, such as hamburger for McDonald’s. Nevertheless, there were varieties of brands available in Malaysian fast food industry nowadays. For example fried chicken for KFC, Marrybrown, pizza for Pizza Hut and Domino Pizza, hot dogs for 1901 Hot Dogs and AMW, hamburger for McDonald’s and Burger King. Furthermore, most of the fast food brands in Malaysian had extended their brand identify to other product category such as Ayam Goreng McDTM, Nasi Marrybrown, O.R. Chicken Chop and so on. Thus, the brand itself no longer represented a single product category; it might cover multiplicity of identification. 115 As a result, the mean score for BA4 would be the lowest (4.06) as compared to other observed variables. Furthermore, the standard deviation was 1.56, the highest among other items, which showed that BA4 was the highest variation among other items and data were spread out over a large range of value as measured up to the mean score. Table 4.10 Descriptive Analysis (Perceived Quality) Scale Items of Perceived Quality Mean Standard Deviation PQ1 The staff of X gives customers individual attention. 4.21 1.15 PQ2 4.52 1.05 4.42 1.06 4.15 1.09 PQ5 The staff of X are well-dressed, clean, and neat. The staff of X provides its prompt services at promised times. The staff of X handles complaints of customers effectively. The staff of X are always willing to help customers. 4.32 1.07 PQ6 The staff of X are knowledgeable. 4.25 1.07 PQ7 The staff of X are confident. X has operating hours convenient to all of its customers. X maintains its food quality. 4.26 1.08 4.54 1.01 4.47 1.06 4.22 1.08 4.46 1.05 PQ3 PQ4 PQ8 PQ9 PQ10 X insists on error-free service. PQ11 The physical facilities of X are visually appealing (e.g. dining areas decorations, building). The highest mean score was PQ8 (4.54) “X has operating hours convenient to all of its customers”, followed by PQ2 (4.52) “The staff of X are well-dressed, clean, and neat”. The result explained that the selected brands had provided satisfactory services to their customers. The lowest mean score was PQ4 (4.15), which was related to customer’s complaints. Therefore, fast food managers should put more effort in handling customer feedback or complaint efficiently, for instance immediate replacement for complaints, cash refund for wrong order, verbal apologize statements and so on. 116 Table 4.11 Descriptive Analysis (Brand Image) Scale Items of Brand Image Mean Standard Deviation BI1 Delicious 4.63 1.01 BI2 Easy 4.73 0.97 BI3 Prompt service 4.55 0.97 BI4 Good dining environment 4.47 1.07 BI5 Pleasant 4.47 1.01 BI6 Free WiFi 4.23 1.33 BI7 Good customer service 4.39 1.09 BI8 A place for social gathering 4.32 1.18 BI9 Variety of choices 4.32 1.12 BI10 Good value for money 4.35 1.16 BI11 Convenient 4.54 1.04 BI12 Widely distributed 4.31 1.10 BI13 Long history 4.26 1.13 Brand image was measured by 13 items as reported in Table 4.11. The question was illustrated as “To what extent do you agree the following characteristics are descriptive of X?” which was adopted from Park (2009). The higher average scores were BI2 (4.73) “Easy”, followed by BI1 (4.63) “Delicious” and BI3 (4.55) “Prompt service”. Brand image was defined as overall image that was formed from the result of both cognitive and affection images towards fast food brand. Thus, it could be referred to as usage imagery (Keller, 1993), emotional benefit and self-expressive benefit (Aaker, 1996). For instance, “Pleasant” was the positive feeling that linked to brand while “Easy” was a symbol of a person’s self-concept that was derived from brands. 117 Alternatively, BI6 “Free WiFi” scored the lowest mean, 4.23. This result indicated that the functional benefits such as Free WiFi, was not perceived as an essential criteria for the creation of brand image when evaluated for emotional or selfexpressive benefit. Table 4.12 Descriptive Analysis (Brand Familiarity) Scale Items of Brand Familiarity Mean Standard Deviation BF1 I am familiar with X. 4.56 1.21 BF2 I have been to X multiple times. 4.44 1.34 BF3 I am knowledgeable of X. 4.14 1.25 BF4 I can easily recognize X. 4.53 1.20 Table 4.12 described the scale items of brand familiarity, BF1 “I am familiar with X” scored 4.56, indicated the highest among the 4 observed variables. The lowest value was 4.14, which was BF3: “I am knowledgeable of X”. Remarkably, the standard deviation for BF2 “I have been to X multiple times” was obviously greater than other items, 1.34, which showed that BF2 was high variability. Table 4.13 Descriptive Analysis (Brand Trust) Scale Items of Brand Trust Mean Standard Deviation BT1 X is safe to me. 4.37 1.18 BT2 X is reliable to me. 4.36 1.14 BT3 I trust X. 4.36 1.15 BT4 X is dependable to me. 4.12 1.23 118 There were high consistency of measurements items (BT1, BT2, and BT3) for brand trust as indicated in Table 4.13, mean values were 4.37, 4.36, and 4.36 respectively. In the same vein, BT4 “X is dependable to me” did not show consistent values for both mean and standard deviation as compared to others. However, the result concluded that most of the consumers consistently ranked the trust level across selected brands. In other words, consumers relied on established fast food brands due to the nature in operations. Table 4.14 Descriptive Analysis (Attitudinal Brand Loyalty) Mean Standard Deviation ABL1 If I had to do it over again, I would choose X. 4.18 1.17 ABL2 I try to visit X because it is the best choice for me. 4.03 1.18 ABL3 I consider myself to be a loyal customer of X. 3.89 1.27 ABL4 X is special to me. 3.85 1.27 ABL5 I would love to recommend X to my friends. 4.08 1.25 Scale Items of Attitudinal Brand Loyalty The highest value of observed variables was 4.18, ABL1: “If I had to do it over again, I would choose X”. The value of ABL1 was the highest as the statement request a lower level of brand commitment as compared to other items. However, higher level of brand commitment that related to best choice, loyal customer, special and recommendations to others (ABL2 to ABL5) were proven to have lower mean scores. 119 Table 4.15 Descriptive Analysis (Brand Equity) Scale Items of Brand Equity BE1 BE2 It makes sense to visit X instead of any other brand, even if they are the same. Even if there is another [fast food category] brand as delicious as X, I still prefer X.

Yet, only BE2, BE3, and BE4 indicated the overall assessment of brand equity on a particular food category. 4.3 Normality According to Bagozzi and Yi (1988), the first things that should be performed for the assessment of structural model were to ensure that all the data input were normally distributed and the statistical assumption was identified. The estimation of SEM parameters required continuous data with normal distribution (Hair et al, 2010). According to Tong (2006), skewness and kurtosis could be used to determine the test for normality. A common rule-of-thumb for normal distribution data was the observed variables should be ranged within absolute value of 2 (Tong, 2006). The normality analysis for 45 observed variables were conducted by AMOS 16.0. The results indicated that the values of skewness and kurtosis of all the observed variables were within absolute value of 2 (see Table 4.16). This means that they were normally distributed. 120 Table 4.16 Skewness and Kurtosis of Observed Variables Constructs Observed Variable Brand awareness BA1 BA2 BA3 BA4 BF1 BF2 BF3 BF4 PQ1 PQ2 PQ3 PQ4 PQ5 PQ6 PQ7 PQ8 PQ9 PQ10 PQ11 BI1 BI2 BI3 BI4 BI5 BI6 BI7 BI8 BI9 BI10 BI11 BI12 BI13 Brand familiarity Perceived quality Brand image 121 Skewness Kurtosis -0.73 -0.57 -0.43 -0.30 -0.61 -0.64 -0.40 -0.69 -0.49 -0.61 -0.69 -0.30 -0.46 -0.37 -0.47 -0.41 -0.62 -0.42 -0.26 -0.44 -0.70 -0.46 -0.65 -0.47 -0.67 -0.51 -0.59 -0.54 -0.65 -0.45 -0.32 -0.33 -0.07 -0.22 -0.67 -1.03 -0.15 -0.13 -0.19 0.17 0.05 0.47 0.67 -0.11 0.19 0.05 0.14 -0.11 0.52 0.27 -0.55 -0.12 0.60 0.26 0.61 0.27 0.00 0.08 0.01 0.24 0.30 0.08 -0.39 -0.14 Table 4.16 Skewness and Kurtosis of Observed Variables (Continued) Constructs Observed Variable Brand trust BT1 BT2 BT3 BT4 ABL1 ABL2 ABL3 ABL4 ABL5 BE1 BE2 BE3 BE4 Attitudinal brand loyalty Brand equity Skewness Kurtosis -0.63 -0.60 -0.60 -0.56 -0.43 -0.40 -0.31 -0.29 -0.48 -0.53 -0.41 -0.40 -0.37 0.31 0.52 0.43 0.22 -0.07 -0.16 -0.19 -0.27 -0.06 0.07 -0.29 -0.29 -0.34 4.4 Structural Equation Modeling (SEM) SEM technique was employed to test the proposed model fit. The proposed model consisted of five endogenous constructs (brand familiarity, brand image, brand trust, attitudinal brand loyalty, and brand equity) and two exogenous constructs (brand awareness and perceived quality). In SEM, researchers reached a consensus that “validity is the most important concept in measurement” (Patterson 2000, p. 17). The measurement scale was first tested for reliability and validity, and then only followed by assessment on structural model for hypotheses testing (Hair et al, 2010). To test the validity of measurement model, confirmatory factor analysis (CFA) was employed to assess, develop, and modify the proposed model. 122 4.5 Confirmatory Factor Analysis (CFA) CFA was conducted by using a correlation matrix for all the constructs, it served as a purpose to investigate the items of each construct more strictly (Hair et al, 2010). In particular, it was used to provide evidence for the underlying construct to be represented by a set of unique observed variables (Anderson & Gerbing, 1988). Gerbing and Anderson (1988) highlighted the importance of uni-dimensionality in the scale development process. They further argued that the traditional exploratory analyses were not theory based analysis and hence they failed to assess unidimensionality directly. To overcome this limitation, confirmatory factor analysis (CFA) was employed for the assessment of measurement model fit and unidimensionality (Hair et al, 2010). This study had identified the number of observed variables (factors) that could be loaded for each of the constructs (latent variables). CFA was performed before the result for the interpretation of dimensionality was determined (Hair et al, 2010). As a result, it provided a more rigorous test for the measurement theory; this was because the assessment of measurement model was performed by a numbers of constructs (latent variables), which were derived from different groups of observed variables that was not directly measured (Hair et al., 2010). The assessment of measurement model served as an important step in providing confirmatory assessment for convergent and discriminant validity (Anderson & Gerbing, 1988). Both convergent and discriminant validity had to be satisfied before it could be transformed to structural model (Hair et al, 2010). Therefore, a good measurement model was considered as a foundation for the estimation of structural model (Hair et al, 2010). The following section covers important discussions relating to CFA which includes the assessment of measurement model and structural model validity. 123 1 e4 1 e3 1 e2 1 e1 BA4 BA3 BA2 BA1 1 Brand Awareness BF4 BF3 BF2 BF1 1 Brand Familiarity 1 e8 1 e7 1 e6 1 e5 1 e191 e181 e171 e161 e151 e141 e131 e121 e111 e101 e9 PQ11 PQ10 PQ9 PQ8 PQ7 PQ6 PQ5 PQ4 PQ3 PQ2 PQ1 e321 e311 e301 e291 e281 e271 e261 e251 e241 e231 e221 e211 e20 BI13 BI12 BI11 BI10 BI9 BI8 BI7 BI6 BI5 BI4 BI3 BI2 BI1 1 Perceived Quality 1 Brand Image 1 1 e361 e351 e341 e33 BT4 BT3 BT2 BT1 1 ABL5 ABL4 ABL3 ABL2 ABL1 1 BE4 BE3 BE2 BE1 1 Brand Trust 1 e411 e401 e391 e381 e37 A. Brand Loyalty 1 e451 e441 e431 e42 Brand Equity Figure 4.1 Initial Measurement Model (CFA 1) 124 4.5.1 Assessment of Fit and Uni-dimensionality of the Measurement Model The initial measurement model had incorporated seven latent variables, which was indicated by respective items pertaining to each scale: brand awareness, brand familiarity, perceived quality, brand image, brand trust, attitudinal brand loyalty, and brand equity. The details of the goodness-of-fit measures for the measurement models (CFA 1 to CFA 21) are presented in Table 4.17. Concerning construct validity criteria, observed variables with standardized loading lower than 0.70 were removed to make certain of the ideal results (Hair et al., 2010). Specifically, BI6, BA4, PQ11, PQ8, BI12, BI13, BI8, and PQ9 were gradually eliminated, which had led to the modification of measurement models from CFA 1 to CFA 9. Next, any pair items of standardized residuals (SD) with greater than l4.0l were removed, as well as those pair items between l2.5l and l4.0l was given attention (Hair et al. 2010). CFA 9 did not present in any pairs observed variables of SD that higher than absolute value of 4.0, however, PQ10 was found to have significant pair numbers of SD between l2.5l and l4.0l with other observed variables (BI7 = SD 3.854, BE1 = SD 3.092, BL4 = SD 3.229, BT4 = SD 3.690, BT3 = SD 2.696). Thus, PQ10 was confiscated and guided to CFA 10. Byrne (2010) stated that observed variables on a measuring instrument should clearly target only one of its underlying constructs, hence cross-loading incurred if an observed variable had two more factor loadings exceeding the threshold value (Hair et al, 2010). The measurement models (CFA 11 to CFA 21) indicated that BE1, BI7, BF2, BT4, PQ7, BI1, BI2, ABL1, PQ6, PQ2, and BI11 were progressively eradicated based on modification indices (MIs) as provided in AMOS 16. The final modified model (CFA 21) is shown in Figure 4.2. 125 Table 4.17 Goodness-of-fit Results for the Measurement Models Model χ² χ²/df RMSEA SRMR GFI CFI NFI IFI TLI Action CFA 1 4,199.790 4.545 0.078 0.065 0.738 0.859 0.826 0.859 0.849 CFA 2 4,036.282 4.581 0.078 0.064 0.745 0.862 0.831 0.863 0.852 Deleted BI6 CFA 3 3,781.380 4.507 0.077 0.061 0.753 0.869 0.838 0.869 0.859 Deleted BA4 CFA 4 3,627.216 4.545 0.078 0.061 0.757 0.872 0.842 0.872 0.861 Deleted PQ11 CFA 5 3,436.309 4.533 0.078 0.060 0.767 0.876 0.847 0.876 0.866 Deleted PQ8 CFA 6 3,125.070 4.346 0.076 0.059 0.779 0.885 0.857 0.886 0.876 Deleted BI12 CFA 7 2,984.093 4.382 0.076 0.058 0.783 0.888 0.860 0.889 0.878 Deleted BI13 CFA 8 2,785.494 4.325 0.075 0.058 0.791 0.894 0.867 0.894 0.884 Deleted BI8 CFA 9 2,604.816 4.284 0.075 0.054 0.800 0.898 0.872 0.899 0.889 Deleted PQ9 CFA 10 2,514.691 4.389 0.076 0.053 0.801 0.899 0.873 0.899 0.889 Deleted PQ10 CFA 11 2,293.898 4.256 0.075 0.051 0.808 0.904 0.879 0.905 0.894 Deleted BE1 CFA 12 2,128.374 4.206 0.074 0.049 0.816 0.909 0.884 0.909 0.899 Deleted BI7 CFA 13 2,014.189 4.249 0.075 0.047 0.819 0.910 0.886 0.910 0.900 Deleted BF2 CFA 14 1,885.109 4.255 0.075 0.045 0.825 0.913 0.889 0.913 0.902 Deleted BT4 CFA 15 1,745.952 4.227 0.074 0.044 0.833 0.916 0.893 0.916 0.906 Deleted PQ7 CFA 16 1,590.951 4.143 0.073 0.042 0.845 0.921 0.899 0.921 0.911 Deleted BI1 CFA 17 1,418.878 3.986 0.072 0.040 0.856 0.928 0.906 0.928 0.918 Deleted BI2 CFA 18 1,209.081 3.675 0.068 0.039 0.871 0.937 0.915 0.937 0.927 Deleted ABL1 CFA 19 1,094.171 3.611 0.067 0.037 0.879 0.941 0.920 0.941 0.931 Deleted PQ6 CFA 20 953.917 3.431 0.065 0.037 0.887 0.947 0.927 0.947 0.938 Deleted PQ2 CFA 21 859.593 3.384 0.064 0.037 0.893 0.950 0.931 0.951 0.942 Deleted BI11 Note: CFA 1 to CFA 9 (Modified as standardized loading estimate < 0.7), CFA 10 (Modified as standardized residuals between l2.5l and l4.0l, CFA 11 to CFA 21 (Modified as factor cross-loadings) 126 1 e3 1 e2 1 e1 BA3 BA2 BA1 1 Brand Awareness BF4 BF3 BF1 1 Brand Familiarity e131 PQ5 e12 1 PQ4 e111 PQ3 e9 PQ1 1 Perceived Quality 1 e8 1 e7 1 e5 1 1 e29 1 BI10 e28 1 BI9 e241 BI5 e231 BI4 e22 BI3 1 Brand Image 1 e351 e341 e33 BT3 BT2 BT1 1 Brand Trust ABL5 ABL4 ABL3 ABL2 1 A.

According to Hair et al. (2010), the significant p-value did not indicate that the observed covariance matrix matched the estimated covariance matrix in the empirical data. Therefore, other goodness-of-fit indices were examined closely given the sensitivity of chi-square statistical test to sample size (Byrne 2010). After the items purification process, final measurement models (CFA 21) consisted of 25 observed variables (see Figure 4.2), the number of observations (N) were 585. Referring to Hair et al.’s (2010) characteristics of different fit indices demonstrating Goodness-of-Fit across different model situation, all fit statistic values proved adequate and obtained values above the recommended value; indicated measurement models had demonstrated perfect results for the degree of uni-dimensionality (χ² = 859.593, χ²/df = 3.384, RMSEA = 0.064, SRMR = 0.037, GFI = 0.893, CFI = 0.950, NFI = 0.931, IFI = 0.951, TLI = 0.942, PCLOSE = 0.06), and the p-value associated with chi-square was 0.001. 4.5.3 Root Mean Square Error of Approximation (RMSEA) In general, there were three reasons for the use of RMSEA. Firstly, model misspecification could be detected as RMSEA emerged to be sufficiently sensitive (Hu & Bentler, 1998). Secondly, RMSEA emerged to become one of the widely used interpretative guideline in determining the quality of assessment model (Hu & Bentler, 1998, 1999). Thirdly, the confidence intervals level could be derived from RMSEA (Byrne, 2010). According to Browne and Cudeck (1993), a value below 0.05 was considered good fit, and value below 0.08 was considered reasonable for the errors of approximation in the population. 128 Nevertheless, the cut-off value of RMSEA (neither 0.05 nor 0.08) could not be confidently concluded that there were absolutely no errors of approximation in the population for the model. In some cases, the value of RMSEA could be small (e.g. 0.04), however the confidence interval was widely ranged (0.02 to 0.10). In this case, the estimation discrepancy value was considered not precise. In order to determine the RMSEA value reflected a model fit in the population, the confidence interval should be narrowly ranged (MacCallum, Browne & Sugawara, 1996). In AMOS software, we could test whether the RMSEA was “good” in the population by indicating value of closeness of fit (PCLOSE) to be greater than 0.05 (Jöreskog & Sörbom, 1996b). The RMSEA value for CFA 21 model was 0.064, with the 90% confidence interval ranging from 0.059 to 0.069 and the PCLOSE value of 0.06, with 90% confident that the true RMSEA value had ranged within the bounds of 0.059 to 0.069, which showed reasonable goodness-of-fit and good degree of precision (Byrne, 2010). This could be further explained with a) The RMSEA point estimate was lesser than 0.08 (0.064), b) The upper bound of RMSEA was 0.069, which indicated the highest value was less than the 0.08 value as suggested Browne and Cudeck, (1993), and c) The PCLOSE value was greater than 0.05 (p = 0.06). As a result, CFA 21 was concluded as a model which fits data well. 4.5.4 Standardized Root Mean Square Residual (SRMR) Specifically, root mean square residual (RMR) was used to identify the value of average residual, which was another descriptive model fit statistic (Byrne, 2010). On the other hand, the standardized RMR (SRMR) represented the average value across all standardized residuals, and the value should be lesser than 0.05 to indicate as a wellfitting model (Bryne, 2010). In this study, RMR value was 0.051 and the SRMR value of CFA 21 was 0.037, which represented that there was an average discrepancy or error of 0.037 between the samples observed and hypothesized correlation matrices (Bryne, 2010). 129 4.5.5 Goodness-of-Fit Index (GFI) GFI could be classified as an absolute index of fit because it basically compared the proposed model with no model at all (Hu & Bentler, 1995). According to Hair et al. (2010), GFI value of greater than 0.90 typically were considered as good. Besides, Jöreskog and Sörbom (1993) highlighted that, theoretically, it was possible for GFI to be negative; Fan, Thompson and Wang (1999) further cautioned that GFI value could be overly influenced by sample size. This, of course, should not occur as it would reflect the fact that the model fits worse than no model at all (Byrne, 2010). The value of GFI was reported as 0.893, slightly below recommended value. Thus, the current study concluded that the final measurement model (CFA 21) fitted the sample data fairly well. 4.5.6 Comparative Fit Index (CFI) The value for CFI was ranged from 0 to 1, which was derived form the comparison of the proposed model against the standard model (Bryne, 2010). Standard model was referred to a baseline model; sometime it was addressed as an independence (or null) model (Bryne, 2010). There were different cutoff values for CFI to represent a well-fitting model as some researchers identified that it should be greater than 0.90 (Bentler, 1992) or 0.95 (Hu & Bentler, 1999). Recently, Hair et al. (2010) suggested a range of cutoff value (0.95, 0.92 or 0.90), which was determined by the number of observed variables and sample size. Referring to CFA 21, there were 25 observed variables and 585 number observations. Therefore, the cutoff value of 0.92 was considered adequate (Hair et al., 2010). Table 4.17 presents the proposed model which is well fitted, sufficiently described by the sample data (CFI: 0.950). On the other hand, the Normed Fit Index (NFI) value had also indicated that the proposed model was only marginally fitted (0.931). However, some researchers suggested choosing CFI value as model fit indicator, this was because CFI did not encounter a problem for estimating fit in small samples (Bentler, 1990; Byrne, 2010). 130 4.5.7 Incremental Fit Index (IFI) IFI had the similar computation with Normed Fit Index (NFI). However, it excluded the consideration of taking account into degrees of freedom (Bollen, 1989). It was used to determine the issues of parsimony and sample size of the proposed model. According to Hu and Bentler (1999), the cutoff value of 0.95 was considered good. Referring to Table 4.17, it was not surprising that the value of IFI (0.951) was close to the CFI value, which reflected the proposed model as a well-fitted model. 4.5.8 Tucker-Lewis Index (TLI) TLI was theoretically identical to the NFI, but it varied in that it was actually a comparison of the normed chi-square values for the null and specified model, which to some degree took into account model complexity (Bryne, 2010). Consistent with other indices, TLI yields values ranging from 0 to 1 (Byrne, 2010). According to Hair et al. (2010), model with a higher value suggested a better fit than a model with lower value. As shown in Table 4.17 (TLI = 0.942), CFA 21 was considered as a good fit model as it was just slightly below cutoff value of 0.95 (Hu & Bentler, 1999). 4.5.9 Measurement Model Identification According to Hair et al. (2010), an additional requirement for SEM was identification, which was referred to the idea whether enough information existed to identify a solution to a set of structural equations. In other words, there was at least one unique distinct sample moments for each parameter to be estimated in the SEM model (Hair et al., 2010). In SEM model, one parameter could be estimated for each unique variance and covariance in the observed covariance matrix. Thus, the covariance matrix provided the degree of freedom used to estimate parameters just as the number of respondents provided degree of freedom in regression (Hair et al., 2010). 131 Even though more items did produce higher reliability estimates and generalizability (Bacon, Sauer & Young, 1995), more items also required larger sample sizes, thus making it difficult to produce truly uni-dimensional factors. According to Hair et al. (2010), models and even constructs could be characterized by their degree of identification, which was defined by the degree of freedom of a model after all the parameters to be estimated were specified. There were three levels of identification models, namely under-identified model, just-identified model, and over-identified model (Hair et al., 2010). Over-identified models had more unique covariance and variance terms than parameters to be estimated, which could be identified with a positive degree of freedom and a corresponding chi-square of goodness-of-fit value (Hair et al., 2010).

Of the CFA 1 = 163 / CFA 21 = 103 total parameters in the measurement models, only CFA 1 = 111 / CFA 21 = 71 were to be freely estimated; all other CFA 1 = 52 / CFA 21 = 32 had fixed parameters in the models (i.e., they were constrained to equal 1 value). As a consequence, the initial (CFA 1) and final (CFA 21) measurement models were over-identified with 924 and 254 degree of freedom respectively. 132 Table 4.19 Summary of Final Measurement Model (CFA 21) Parameters Weights Covariance Variances Means Intercepts Total Fixed 32 0 0 0 0 32 Labeled 0 0 0 0 0 0 Number of distinct parameters to be estimated 18 21 32 0 0 71 50 21 32 Total Note.

(2010), reliability was used to measure the internal consistency of the construct (latent variable). It highlighted the degree of unobserved factor in the construct. In SEM, construct reliability (CR) had to be tested prior to construct validity, however, CR was one of the indicators for convergent validity (Hair et al., 2010), and the formula as presented in next page. 133 {Σ(SLi)} ² -------------------------{Σ(SLi)} ² + {Σ(ei)} Σ = Sum SLi = Factor loading ei = Error variance terms for a construct The most commonly used threshold for CR measures was 0.70 or higher (Nunnally, 1978), which indicated the existence of internal consistency, in other words; the observed variables had consistently measured the same latent variable (Hair et al., 2010). Referring to Table 4.20, the CR values had ranged from 0.86 to 0.94, enormously above the cutoff value of 0.70, which indicated high internal consistency for all the constructs in this study. 4.5.11 Construct Validity Establishing construct validity of the measurement model was essential in confirming the accuracy of measurement (Hair et al., 2010). Construct validity assessed the degree to which a scale or a set of measured items actually represented the theoretical latent variable in the model (Hair et al., 2010). Therefore, it dealt with the accuracy of measurement which provided the assurance to the observed items of the survey reflected the real score that existed in the population (Hair et al., 2010). The present study adopted Hair et al.’s (2010) measurement validation procedures to test construct validity. Prior to structural model testing, the construct validity was tested by checking the convergent validity, discriminant validity, and nomological validity (Hair et al., 2010). The whole process of scale validation was delineated in the following sub-sections. 134 4.5.12 Convergent Validity According to Kline (2005), measurement model presented the relationships between the observed variables with the unobserved constructs (latent variables). Therefore, convergent validity was employed in investigating to what extent that the observed variables could converge or share a high proportion of variance within the unobserved constructs (Hair et al., 2010). The convergent validity was assessed by checking the loading of each observed indicator on their underlying unobserved constructs (Anderson & Gerbing 1988). Table 4.20 presented three indicators for convergent validity, which included standardized factor loading, average variance extracted and construct reliability (Hair et al., 2010). 4.5.13 Standardized Factor Loadings Table 4.21 presented standardized factor loading, t value as well as average variance extracted for each latent variable. Firstly, the standardized factor loading (i.e., the path estimate linked construct to observed variables) were examined to identify potential problem with the CFA 21 model. Referring to Hair et al. (2010), the standardized factor loading for each of the observed variables were proposed to have at least 0.50 and ideally exceed 0.70, such condition had given evidenced that there was a significant link between the observed variables and latent variable. For this reason, low loading estimate were removed (CFA 1 to CFA 9 in Assessment of Fit and Unidimensionality of the Measurement Model section) to avoid potential measurement problem. The results of final measurement model (CFA 21) (see Table 4.21) indicated that each standardized factor loading were statistically significant at 0.001 levels. The t values for each of the observed variables were considered above the rule of 1.65 t value (Yoo et al., 2000). In addition, the standardized factor loading had ranged from 0.71 (BA1 & BI10) to 0.94 (BT2), and no factor loading was less than the ideal level of 0.70 (Hair et al., 2010). 135 Table 4.21 Final Results of the Analysis of Convergent Validity Brand equity dimensions Items Standardized factor loadings T value Brand awareness BA1 BA2 BA3 BF1 BF3 BF4 PQ1 PQ3 PQ4 PQ5 BI3 BI4 BI5 BI9 BI10 BT1 BT2 BT3 ABL2 ABL3 ABL4 ABL5 BE2 BE3 BE4 0.71 0.90 0.83 0.81 0.80 0.83 0.79 0.87 0.84 0.83 0.78 0.79 0.75 0.76 0.71 0.92 0.94 0.88 0.89 0.85 0.89 0.88 0.91 0.92 0.92 19.44 18.31 21.01 21.86 23.38 22.24 21.83 19.53 18.52 18.54 17.39 39.41 33.38 28.89 31.36 30.80 35.61 36.56 Brand familiarity Perceived quality Brand image Brand trust Attitudinal brand loyalty Brand equity Average Variance Extracted 0.67 0.67 0.69 0.58 0.83 0.77 0.84 Notes: – means the path parameter was set to 1, therefore, no t value was given; all loadings are significant at 0.001 level. 136 4.5.14 Average Variance Extracted (AVE) Other than fulfilling the factor loadings and item reliability criteria, the convergent validity assessment also included the measure AVE (Hair et al., 2010). According to Fornell and Larcker (1981, p.45), AVE was referred to as “the amount of variance that is captured by the construct in relation to the amount of variance due to measurement error”. Furthermore, Fornell and Larcker (1981) suggested that AVE to be a more conservative measurement than construct reliability. AVE was an indicator of convergent validity and it was proposed to have at least 0.50 or higher (Hair et al., 2010; Fornell & Larcker, 1981). Higher AVE values signified that the indicators were representative of the latent variable (Hair et al., 2010). The initial formula of AVE is illustrated in formula 1. Besides, there was another formula for AVE as presented by Hair et al. (2010), which highlighted AVE to be simplified as the total of squared standardized factor loadings divided by the number of observed variables, as indicated in formula 2. Σ (SLi) ² --------------------Σ(SLi) ² +Σ(ei) Σ (SLi) ² --------------------n Formula 1 Formula 2 Σ = Sum SLi = Factor loading ei = Error variance terms for a construct n = Nnumber of observed variables in the latent variable Table 4.21 showed that all the AVE values of constructs were above 0.50, ranged from 0.58 to 0.84, meaning to express that less than 50% of the error remained in the terms than variance explained by the latent factor structure imposed on the measure (Hair et al., 2010). That is, the observed variables were significantly represented its latent variables respectively. As a result, the test indicated that all the latent variables had satisfied the convergent validity. 137 4.5.15 Discriminant Validity In addition to convergent validity, discriminant validity analysis was also needed to be considered in this study. This was because it served as a test to ensure that all the constructs (latent variables) that was uniquely derived from the observed variables, and were not highly correlated (Hair et al., 2010). That is, each of the constructs is distinguishable and there is no overlapping of constructs in the measurement model (Hair et al., 2010). The average variance extracted (AVE) estimated in each construct had exceeded the squared inter-construct correlations associated with constructs in the model (Hair et al., 2010; Fornell & Larcker, 1981). The logic here was based on the idea that a construct should explain more of the variance in its item measures when it was shared with another construct (Hair et al., 2010). Table 4.22 presented the results for discriminant validity. It was found that the AVE of each constructs was above squared correlation with other constructs. The result provided evidence that the seven constructs were unique and captured some phenomena where other measures did not. It was evident that these results provided adequate evidence for discriminant validity of the final measurement model (CFA 21). 4.5.16 Nomological Validity According to Hair et al. (2010), nomological validity was used to examine whether the correlations among the constructs in a measurement theory made any sense, and it could be assessed by the matrix correlations among the constructs. As indicated in Table 4.22, correlations among the constructs were statically significant (p<0.01), ranged from 0.27 to 0.87. An investigation of the final measurement model (CFA 21) results revealed that none of the indicators were found to be problematic. According to this assessment, the measures in the main study were adequate and the scales exhibited high convergent, discriminant and nomological validity (Gil et al. 2007; Hair et al., 2010; Malär et al, 2011; Park et al., 2010). 138 Table 4.22 Result of the Discriminant Validity Analysis Construct (AVE) 1.

The structural relationships between constructs were represented empirically by the structural parameter estimate, also known as a path estimate (Hair et al., 2010). Structural models were referred to by several terms, including a theoretical model or, occasionally, a causal model (Hair et al., 2010). CFA 21 tested measurement theory by providing on the validity of individual measures based on the model’s overall fit and other evidence of construct validity as discussed previously. However, CFA 21 alone was limited in its ability to examine the nature of relationships between constructs (Hair et al., 2010). Next, this study focused on the structural model and hypothesized relations among the seven constructs. According to Hair et al. (2010), the hypothesized model will be supported if (1) the model had showed a good fit, and (2) the hypothesized paths were significant (e.g. significance relationship for H1 to H12). In addition, hypothesized model with satisfied goodness-of-fit indices did not mean that some alternative model(s) might not fit better or be more accurate (Hair et al., 2010). The relationships in the structural model had to be consistent with the theory that suggested they should be a positive or negative. If the relationships did not make senses, they should not be relied upon (Hair et al., 2010). Besides, model re-specifications were conducted for the purpose to identify the best model (Hair et al., 2010). The additional proposed models were examined via three distinctive steps. Firstly, the re-specified models should meet all the goodness-of-fit indices, which applied the same empirical data as employed for the original proposed model (Hu & Bentler 1999). Secondly, the significant levels for each of the path estimates were examined for the re-specified models (Hair et al., 2010). Thirdly, the squared multiple correlations for each of the endogenous were examined to determine the proportion of variance that was explained by the predictors in the structural model (Hair et al., 2010). 140 4.6.1 Specifying the Structural Model Model specification was defined as to how a research framework was represented in a visual diagram (Hair et al., 2010). These processes included determining the approach unit analysis, representing the research framework in a path diagram, clarifying which constructs were exogenous and endogenous, and several related issues such as sample size and identification (Hair et al. 2010). In a structural model (known as visual diagram or path diagram), fixed parameter was the relationship that would not be tested or hypothesized on the structural equation modeling routine; it was typically assumed to be set as zero and were not shown on the structural model or path diagram (Hair et al. 2010). Free parameters were relationships that would be estimated; they were generally depicted by an arrow in the structural model (Hair et al. 2010). Figure 4.3 showed both fixed and free parameters. For instance, no relationship was specified between Brand Equity and Brand Awareness. Therefore, no path estimate (arrow) was shown, and the theory assumed that this path was fixed at zero. On the other hand, there was a path between Brand Equity and Attitudinal Brand Loyalty that represented the relationship between these two constructs and for which a parameter was estimated. Referring to Figure 4.3, the parameters represented structural relationships among the constructs. According to Hair et al. (2010), there are three ways where the correlation and regression coefficients could be interpreted in this model: (1) relationships between two exogenous constructs, (2) relationships between exogenous and endogenous constructs and (3) relationships between two endogenous constructs. 141 e50 1 1 Brand Equity 1 BE2 1 e43 BE3 1 e44 BE4 e45 e49 1 1 A.

In this process, it involved a series of changes, such as notation and substantive issues (for example changing from exogenous to endogenous constructs). The following sections describe the theoretical and notational changes involved in the process. 4.6.3 Theoretical Change As illustrated previously, the structural theory was specified by using free parameters (those to be estimated) and fixed parameters (those fixed at zero value) to represent twelve hypothesized relationships. However, in specifying the structural relationships, two other significant changes had occurred. Firstly, a distinction was made between endogenous and exogenous constructs (Hair et al., 2010). Secondly, an error term was associated with endogenous constructs as they were not fully explained (Hair et al., 2010). Based on the proposed framework in this study, there were two exogenous constructs and five endogenous constructs. Brand awareness and perceived quality were exogenous construct as there was no arrow pointing on them. Brand Equity, Attitudinal Brand Loyalty, Brand Trust, Brand Image, and Brand Familiarity were endogenous (arrows pointing on it), based on research framework of this study. Therefore, as compared to CFA 21, the relationships among constructs had changed entirely. There was a correlation between Brand Awareness and Perceived Quality, and other constructs had indicated to have the path relationships (causal effect). Consequently, only one covariance (correlation relationship) was shown in the proposed model, and other relationships between the constructs were represented by path coefficient. 143 No relationships were shown between Brand Equity and other constructs (Brand Familiarity, Brand Trust, Brand Image, and Perceived Quality or Brand Awareness) except Attitudinal Brand Loyalty, as well as no relationship between Attitudinal Brand Loyalty and Brand Awareness or Brand Familiarity. This was because they were fixed to zero, in other words, this study did not hypothesize direct or causal relationships in the research framework as there were theoretically justified in Chapter 3. 4.6.4 Notational Change Five new terms appeared, e46 to e50 (Figure 4.3). They represented the error variance of the prediction for the five endogenous constructs (Hair et al., 2010). After these error variances were standardized, they were demonstrated as R2. Particularly, they were similar to the residual in regression analysis (Hair et al., 2010). 4.6.5 Structural Model Identification The computation of degrees of freedom in a structural model were the same as the indicated in measurement model, except in the variation of estimated parameters (Hair et al., 2010). This was because the numbers of observed variables had not changed; neither did the total number of degree of freedom available (Hair et al., 2010). Table 4.23 shows the total of 325 number of distinct sample moments had corresponded to CFA 21 as both models had the identical observed variables, but the degree of freedom now differed in the relationships between the seven constructs. Referring to Table 4.23, it was noticed that there was changes of the numbers of distinct parameters to be estimated (free parameters) for weight and covariance as compared to Table 4.19. This was because the weights parameter was increased from 18 to 29, extra 11 path parameters (causal effects) were added, these could be explained by the additional hypothesized path relationship (H2 to H12). 144 Table 4.23: Summary of Structural Model Parameters Weights 37 0 Covariance 0 0 Variances 0 0 Fixed Labeled Number of distinct parameters to 29 1 32 be estimated 66 1 32 Total Note. Number of distinct sample moments = 325 Degrees of freedom (325 - 62) = 263 Means 0 0 Intercepts 0 0 0 0 0 0 Total 37 0 62 99 Nevertheless, the numbers of covariance were reduced from 23 to 1; only one hypothesized correlation relationship (represented H1) was remained in the research framework. Consequently, the model of current study indicated 263 degree of freedom, which highlighted that the structural model was over-identified (Hair et al., 2010). 4.6.6 Justification of Recursive Model The proposed brand equity structural model was considered as a recursive model as the paths between constructs all proceed only from the predictor constructs to the outcome constructs without any feedback loop (Hair et al., 2010). Therefore, the research framework of this study indicated that it did not contain any constructs that were both determined by some predictors and at the same vein assisted in determining that predictors (Hair et al., 2010). In other words, there was no pair of constructs which had arrows going both ways between them. Nonrecursive model existed when the model contained feedback loops (Hair et al., 2010). A feedback loop was considered when a construct was seen as a playing role for both predictor and outcome of another single construct. Most of the time, nonrecursive model seem to have problems with statistical identification as a unique estimate for a single parameter may no longer exits (Hair et al., 2010). 145 4.6.7 Assessing the Structural Model Validity The hypothesized brand equity structural model (see Figure 4.3) was then tested for model fit. Prior to model testing, the standardized loading estimates for the structural model were examined to ensure that there were no problems associated with interpretational confounding as compared to final measurement model (Hair et al., 2010). According to Hair et al. (2010), since the same set of observed variables was used for both final measurement and structural models, there were rationality to fix the value of standardized loading estimates for each of the observed variable as these values were not subject to change just because of the structural model. The advantage to this approach was that the structural model was easier to estimate because there were more parameters which had values that were fixed. A disadvantage was that the change in fit between the final measurement model and the structural model could have been due to problems with the measurement instead of with the structural theory (Hair et al., 2010). In order to reduce the possibility of the disadvantage as discussed, method such as comparing the standardized loading estimates between final measurement model and structural model could be executed (Hair et al., 2010). If the standardized loading estimates varied substantially, then there was evidence of interpretational confounding (Hair et al., 2010). Small fluctuations as long as below 0.05 were acceptable (Hair et al., 2010). The beauty of this approach was that the original final measurement model fit became a convenient basis of comparison in assessing the fit for the structural model (Hair et al., 2010). Table 4.24 showed that the standardized loadings estimates were virtually unchanged from the CFA 21 result. Even though eight estimated standardized loadings were changed (BF1, BF4, BI3, BI4, BT1, & BT2), however the maximum changes was only 0.01, and importantly, all the construct reliabilities were identical. Thus, if parameter stability had not already been tested in the CFA stage, there would be evidence of stability among the observed indicator variables (Hair et al., 2010). As a conclusion, the result showed that all the indicators were found to have no problem in supporting the validity of measurement of model and no evidence for interpretational confounding (Hair et al., 2010). 146 Table 4.24 Comparison of Standardized Factor Loadings and Construct Reliabilities for Hypothesized and CFA 21 Models Proposed model Brand equity dimensions Brand awareness Brand familiarity Perceived quality Brand image Brand trust Attitudinal brand loyalty Brand equity Items BA1 BA2 BA3 BF1 BF3 BF4 PQ1 PQ3 PQ4 PQ5 BI3 BI4 BI5 BI9 BI10 BT1 BT2 BT3 ABL2 ABL3 ABL4 ABL5 BE2 BE3 BE4 SFL 0.71 0.90 0.83 0.82 0.80 0.84 0.79 0.87 0.84 0.83 0.77 0.78 0.75 0.76 0.71 0.91 0.93 0.88 0.89 0.85 0.89 0.88 0.91 0.92 0.92 CR 0.86 0.86 0.90 0.87 0.94 0.93 0.94 CFA 21 Model SFL 0.71 0.90 0.83 0.81 0.80 0.83 0.79 0.87 0.84 0.83 0.78 0.79 0.75 0.76 0.71 0.92 0.94 0.88 0.89 0.85 0.89 0.88 0.91 0.92 0.92 CR 0.86 0.86 0.90 0.87 0.94 0.93 0.94 Notes: SFL=Standardized factor loadings; CR=Construct reliability; All loadings are significant at 0.001 level. 147 4.6.8 Goodness-of-Fit Statistics for Structural Model Next, Table 4.25 reported fit statistics of the overall model fit for proposed brand equity model and the final measurement model (CFA 21). The same set of fit indices of measurement model was used to assess the structural model. The χ² was 917.953 with 263 degrees of freedom (p<0.001) and the normed chi-square was 3.490. The model CFI was 0.946, with a RMSEA of 0.065 and 90% confidence interval of 0.061 to 0.070. The CFI index was substantially above the preferred .92 threshold (Hair et al., 2010). The absolute fit measure of RMSEA was also well below the recommended cut-off of 0.07 to be indicative of good model fit (Hair et al., 2010). All of these measures were within a range that was associated with a good fit as recommended by Hair et al. (2010), provided with 25 observed variables and carried out 585 numbers of observations. According to Hair et al. (2010), the closer the values of goodness-of-fit for both structural model and measurement model, the better the structural model fitted because the measurement model fit provided an upper bound to the goodness-of-fit measures of a conventional structural model. Furthermore, as long as the structural theory was a recursive model, then it could not include more relationship between constructs than the final measurement model from which it was developed (Hair et al., 2010). Consequently, a recursive model could not have a lower χ² value and better model fit than that obtained in final measurement model (Hair et al., 2010). Table 4.25 indicated that values of goodness-of-fit for proposed brand equity model (structural model) changed very little from the CFA 21. The only substantive difference was a chi-square (χ²), which increased of 58.36 and a difference of nine degrees of freedom. As a conclusion, these results are reported in Table 4.25 suggests clear understanding of structural model fit from final measurement model fit. 148 Table 4.25 Comparison of Goodness-of-fit Measures between Proposed Brand Equity and CFA 21 Models Goodness-of-fit index Absolute measures χ² (chi-square) Degrees of freedom χ²/df Probability GFI RMSEA Confidence interval of RMSEA RMR SRMR Brand equity model CFA 21 model 917.953 263 3.490 0.001 0.887 0.065 0.061 - 0.070 0.074 0.050 859.593 254 3.384 0.001 0.893 0.064 0.059 - 0.069 0.051 0.037 Incremental fit measures NFI CFI RFI 0.927 0.946 0.916 0.931 0.950 0.919 Parsimony measures AGFI PNFI 0.860 0.812 0.863 0.789 Note: GFI=Goodness-of-Fit Index, RMSEA=Root Mean Square Error of Approximation, RMR=Root Mean Square Residual, SRMR=Standardized Root Mean Square Residual, NFI=Normed Fit Index, CFI=Comparative Fit Index, RFI=Relative Fit Index, AGFI=Adjusted Goodness-of-Fit Index, PNFI=Parsimony Normed Fit Index. 149 4.6.9 Examining Structural Model Diagnostics In the structural equation modeling (SEM), several diagnostic measures were available to evaluate the SEM models. The diagnostic measures ranged from fit indices to standardized residuals (SR) and modification indices (MIs) (Byrne, 2010). There were three important things which had to be emphasized on while using MIs. Firstly, covariance could only be exercised if the measurement error of the constructs was identical, and it could not be executed by when there was any cross-covariance (Byrne, 2010). Secondly, there were substantive numbers of suggested parameters found from the MIs, however, the action for freeing up the parameter must be theoretically supported and must gradually be exhibited depending on the largest MIs value (Jöreskog & Sörbom, 1993). Lastly, it was important to know where to stop for the model re-specification; which served as the purpose of avoiding over-fitted model (Wheaton, 1987). Residual could be either positive or negative, depending on whether the estimated covariance was under or over the corresponding observed covariance (Hair et al., 2010). Typically, SR less than l2.5l did not suggest a problem, value between l2.5l and l4.0l deserved some attention, but might not suggest any changes to the model if no other problems were associated with those two items, residual greater l4.0l raised a red flag and suggest a potentially unacceptable degree of error (Hair et al., 2010). Table 4.26 showed that there was no SR value that greater than l4.0l, yet, there were seven pairs of SR that fell in between l2.5l and l4.0l. The study indicated that there were no other problems associated with these pair items as there were no significant values such as higher than 4.0 as highlighted by Hair et al. (2010). For this reason, all the observed variables were suggested to be retained in this model. 150 Table 4.26 Model Diagnostic for Proposed Brand Equity Structural Model a.

In other words, serious attention had to be given to those MIs that were greater than l0.10l Δ Par and 10.00 Δ χ² / Δ RW (Byrne, 2010). However, if there were situations where MIs presented greater (lower) than l0.10l Δ Par and lower (greater) than 10.00 Δ χ² / Δ RW, it was suggested to focus on size of the Δ Par, rather than on the Δ χ² / Δ RW (Kaplan, 1989). Turning to the result of MIs for correlation relationships (see Table 4.26), the error covariance related to the same constructs (indicated “Yes” in relevancy column), BI4 & BI5, BI9 & BI10, BI4 & BI10, BI3 & BI9, BI5 & BI10, and ABL3 & ABL5 remained above 10.00 misspecification chisquare in the model (85.04, 46.30, 28.69, 15.50, 14.40, and 12.27 respectively). Only four pairs’ (BI4 & BI5, BI9 & BI10, BI4 & BI10, and BI5 & BI10) estimated parameter change statistic did suggest that this parameters were significant incorporated into the model as the recommended value were above l0.10l (Byrne, 2010). Since the structural model was statistically fitted, it was not necessary for the model respecification to avoid over-fitted model (Wheaton, 1987). In reviewing the MIs for structural relationship, the results suggested to include path coefficients of Brand Familiarity and Brand Awareness on Brand equity (Δ RW = 16.44, Δ Par = 0.13 and Δ RW = 14.53, Δ Par = 0.14). However, there were no theoretical supports for the causal relationships as suggested in MIs. For this reason, the inclusion of both structural relationships would not make sense even if it helped to improve the model fits (Byrne, 2010). Thus, there were no further modifications for the proposed model. In general, the issue of over-fit model was raised when there were over re-specification of additional parameter in the model (Wheaton, 1987). Therefore, if a researcher selects to use SEM, it was vital to understand the analysis to be conducted within the confirmatory mode, rather than exploratory that was based on MIs. In other words, there was the end of SEM analytic approach once the hypothesized CFA or structural model had failed to fulfill the specific criteria (Byrne, 2010). 152 4.7 Results of Hypotheses Testing In Chapter 3, twelve hypotheses were proposed based on theoretical and extensive literature which reviewed for inclusions in the model. Hair et al. (2010) argued that the validation of model was not complete without examining the individual parameter estimates. Consequently, the last part of the validation of model was to determine if there were any significant relationships which existing in the model. Out of twelve hypotheses, nine statements were supported and three hypotheses were rejected due to insignificant statistic. An outline of the hypotheses is presented in Table 4.27, which included unstandardized parameter estimates (b), standardized parameter estimates (β), standard error (se), t value, and statistical significance level (α). Structural parameter estimates or path estimates (including unstandardized and standardized) were comparable as a regression coefficients that measured the linear relationship between predictor construct and an outcome construct in structural equation modeling (Hair et al., 2010). In other words, it reflected the change in the dependent measure for each unit change in the independent variables (Hair et al., 2010). Unstandardized parameter estimates retained scaling information of variables and could only be interpreted with reference to the scales of the variables (Suhr, 2008). In contrast, standardized parameter estimate was the transformation of unstandardized estimates that removed scaling, and it could be further used as an informal comparison of parameters throughout the model (Suhr, 2008). Standardized parameter estimate (standardized coefficient) was calculated from standardized data, thus it allowed for an assessment of practical significance in term of relative predictive power of the added variable (Hair et al., 2010). Standard error (se) was an estimate of how much the structural parameter estimate would vary between samples of the same size taken from the same population, and a smaller standard error implied more reliable prediction and therefore smaller confidence intervals (Hair et al., 2010). 153 Table 4.27 Results of the Hypotheses Correlation estimate H1 Brand awareness ↔ Perceived quality Structural parameter estimates H2 Brand awareness → H3 Brand awareness → H4 Brand familiarity → H5 Brand familiarity → H6 Perceived quality → H7 Perceived quality → H8 Perceived quality → H9 Brand image → H10 Brand image → H11 Brand trust → H12 Attitudinal brand loyalty → Brand familiarity Brand image Brand image Brand trust Brand image Brand trust Attitudinal brand loyalty Brand trust Attitudinal brand loyalty Attitudinal brand loyalty Brand equity b ( 95% CI ) β se 0.24 (0.16-0.32) 0.30 0.04 0.83 (0.71-0.95) -0.07 (-0.17-0.03) 0.31 (0.21-0.41) 0.48 (0.40-0.55) 0.48 (0.41-0.56) 0.10 (0.00-0.20) 0.09 (-0.01-0.19) 0.67 (0.51-0.83) 0.44 (0.26-0.62) 0.46 (0.36-0.56) 0.98 (0.90-1.06) 0.73 -0.09 0.40 0.43 0.59 0.09 0.08 0.46 0.31 0.48 0.86 0.06 0.05 0.05 0.04 0.04 0.05 0.05 0.08 0.09 0.05 0.04 t value α Conclusion 6.04 ** Supported 14.08 ** -1.38 0.17 6.37 ** 10.96 ** 12.65 ** 1.94 0.06 1.84 0.07 8.49 ** 5.00 ** 9.43 ** 24.95 ** Supported Not Supported Supported Supported Supported Not Supported Not Supported Supported Supported Supported Supported Notes: b=Unstandardized parameter estimates, CI=Confidence interval, β=Standardized parameter estimates, se=Standard error, α=Statistical significance level , ** Path analysis is significant at the .001 level 154 The t value was derived from dividing the unstandardized parameter estimates by the standard error (Hair et al., 2010). It was used to measure the significance of the partial correlation of the variable reflected in the structural parameter estimated (Hair et al., 2010). As such, it indicated whether the researcher could confidently conclude, with a stated level of error, that the structural parameter estimated was not equal to zero. Statistical significance level was also known as Alpha (α) or Type I error. It was the probability of rejecting the null hypothesis when it was actually true, generally referred to as a false positive and conventional guidelines suggested α levels of 0.05 or 0.01 (Hair et al., 2010). By specifying an α level, the researcher had set the acceptable limits for error which indicated that the probability of concluding that significance exists when it really did not (Pallant, 2005). As shown in Table 4.27, H1 to H3 examined the relationships between brand awareness and perceived quality, band familiarity and brand image. The correlation between brand awareness and perceived quality was statistically significant (β = 0.30, se = 0.04, t value = 6.04, α < 0.001). The causal relationship for brand awareness on brand familiarity was statistically significant (β = 0.73, se = 0.06, t value = 14.08, α < 0.001). This meant that band familiarity was expected to improve by 0.73 standard deviation; given a change in brand awareness of one full standard deviation, while other variables were controlled (Pallant, 2005). The standard error (se) of structural parameter estimates were 0.04 and 0.06, denoting that the 95% confidence interval for unstandardized parameter estimates (b) would be ranging from 0.16-0.32 and 0.71-0.95 correspondingly. The t values were 6.04 and 14.08, which were statistically significant at the 0.001 level. Brand awareness gave a high level of assurance that the structural parameter estimates were not equal to zero and can be assessed as a predictor of brand familiarity. On the other hand, the result revealed that brand awareness was not positively related to consumers’ brand image (β = -0.09, se = 0.05, t value = -1.38, α = 0.17). Thus, H1 and H2 were supported; however H3 was not evidently proven. 155 H4 and H5 predicted brand familiarity was the foundation of building brand image and brand trust. The results showed significant path analyses, brand familiarity positively influenced brand image (β = 0.40, se = 0.05, t value = 6.37, α < 0.001), and brand trust (β = 0.43, se = 0.04, t value = 10.96, α < 0.001). Hence, H4 and H5 were supported. In testing H6, H7 and H8, it was evident that the perceived high quality of products was likely to help in constructing a favorable brand image (β = 0.59, se = 0.04, t value = 12.65, α < 0.001), yet unsuccessfully in contributing strong brand trust (β = 0.09, se = 0.05, t value = 1.94, α = 0.06) and attitudinal brand loyalty among consumers (β = 0.08, se = 0.05, t value = 1.84, α = 0.07). That is, the perception of Malaysian consumers towards fast food brand image was based on the perceived quality. However, solely depended on quality alone did not support in the creation of brand trust and attitudinal brand loyalty. Therefore, H6 was supported but H7 and H8 were rejected. H9 and H10 proposed that favorite brand image could lead to greater brand trust and strong attitudinal brand loyalty. The results indicated statistical significant effect of brand image on brand trust (β = 0.46, se = 0.08, t value = 8.49, α < 0.001) and attitudinal brand loyalty (β = 0.31, se = 0.09, t value = 5.00, α < 0.001). Focused on the highest se of structural parameter estimates was 0.09, which denoting that the 95% confidence interval for b would be 0.44 ± (1.96 X 0.09), or ranging from the lowest of 0.26 to the highest of 0.62. Even though the range of confidence interval was quite larger, but the t value was 5.00 and statistically significant at the 0.001 level. Therefore, H9 and H10 were supported. H11 argued that brand trust was likely to be a predictor of consumers’ attitudinal brand loyalty. The results from this study supported this proposed causal relationship (β = 0.48, se = 0.05, t value = 9.43, α < 0.001). Lastly, H12 posited the relationship between consumers’ attitudinal brand loyalty and their overall brand equity. The result revealed that overall consumer-based brand equity was significantly predicted by their attitudinal brand loyalty (β = 0.86, se = 0.04, t value = 24.95, α < 0.001). Hence, H11 and H12 were supported. 156 4.8 Model Re-specification: Comparison of Different Models Model re-specification must have strong theoretical as well as empirical support (Hair et al., 2010). It could be executed by considering the diagnostic measures in Structural Equation Modeling (SEM), for instance the modification indices (MIs) that is available in the output of AMOS software (Byrne, 2010). Thus, a further assessment of SEM model in relation to causal effect, which was the post hoc analysis, would be conducted if there were any improvement of the model fit with theoretically justified (Hair et al., 2010). In reviewing MIs, the result revealed that there was evidence of misfit in the proposed model as additional structural relationship (causal effect) was included in the model (see Table 4.26: part c. Modification indices for structural relationship). However, as stated above, any model re-specification should have strong theoretical background in supporting the execution. Since the proposed structural parameter did not have any relevance of theory behind them, thus the proposed model was considered as the final model (Hair et al., 2010). Referring to Table 4.28, the squared multiple correlation (i.e., R² in multiple regression) for brand equity was 0.74, attitudinal brand loyalty (0.62), brand trust (0.67), brand image (0.55), and brand familiarity (0.54). However, squared multiple correlation was not applicable for exogenous constructs such as perceived quality and brand awareness. It was estimated that the predictors of brand equity explained 74 percent of its variance. In the same vein, the error variance of brand equity was approximately 26 percent of the variance of brand equity itself. This could be explained that 74% of variability in brand equity was explained by direct predictor (attitudinal brand loyalty) and indirect predictors (brand trust, brand image, brand familiarity, perceived quality and brand awareness). Consequently, the proposed model was considered as an ideal model as it met all the goodness-of-fit indices and the values of endogenous’ squared multiple correlations were above 0.50. 157 According to Kenny (2011), another strategy to take in re-specifying a model was focusing on theoretically meaningful complications and simplifications of the model. In other words, the re-specification of model could be performed model comparison on other researchers’ concepts, which had strong theoretical justification (Kenny, 2011). As discussed in Chapter 2 and 3, most of the constructs or latent variables were adopted from Aaker’s (1991) and Gil et al.’s (2007) model. Therefore, both of the established theoretical concepts were tested in the structural models to investigate whether there were significant difference of goodness-of-fit indices (GOF), causal relationships (structural parameter estimates), and squared multiple correlation (R²) as compared to the proposed model. Table 4.28 supported that the chi-square for Aaker (A) and Gil et al. (G) models were 549.986, which was significant different from the proposed model (P) by 367.967, with 121 degrees of freedom, and 3.873 normed chi-square (p< 0.05). However, there were not much difference for GFI (P: 0.887, A: 0.907, G: 0.907), RMSEA (P: 0.065, A: 0.070, G: 0.070), Confidence interval of RMSEA (P: 0.061-0.070, A: 0.064-0.076, G: 0.064-0.076), NFI (P: 0.927, A: 0. 938, G: 0. 938), CFI (P: 0.946, A: 0. 953, G: 0. 953), RFI (P: 0.916, A: 0. 925, G: 0. 925), and AGFI (P: 0.860, A: 0. 875, G: 0. 875). Turning to results on relationships among constructs, the findings among three models were consistent and the value for standardized structural parameter estimates did not vary dramatically. For instance, the direct relationships between brand awareness and brand equity was not significant for both A and G models, brand image and attitudinal brand loyalty was significant for both P (0.31) and G (0.58), perceived quality and brand equity was insignificant for A and G models, perceived quality and attitudinal brand loyalty was not significant for P and G models. In additional to that, the path analysis from brand image to brand equity was insignificant for A and G models. Lastly, the result showed a statistically significant causal effect of attitudinal brand loyalty on brand equity among three models (P: 0.86, A: 0.91, G: 0.91). 158 Figure 4.4: Implication of Aaker’s Model (1991) Note: BA=Brand awareness, PQ=Perceived quality, BI=Brand image, ABL=Attitudinal brand loyalty, BE=Brand equity Figure 4.5: Implication of Gil at al.’s Model (2007) 159 Table 4.28 Comparison of Structural Models Goodness-of-fit index χ² (chi-square) Degrees of freedom χ²/df Probability GFI RMSEA Confidence interval of RMSEA RMR SRMR NFI CFI RFI AGFI PNFI Parameter estimates BA ↔ PQ BA → BF BA → BI BA → ABL BA → BE BF → BI BF → BT BF → ABL BF → BE PQ → BI PQ → BT PQ → ABL PQ → BE BI → BT BI → ABL BI → BE BT → ABL BT → BE ABL → BE Proposed Model Aaker Gil et al. 917.953 263 3.490 0.001 0.887 0.065 0.061 - 0.070 0.074 0.050 0.927 0.946 0.916 0.860 0.812 549.986 142 3.873 0.001 0.907 0.070 0.064-0.076 0.052 0.039 0.938 0.953 0.925 0.875 0.779 549.986 142 3.873 0.001 0.907 0.070 0.064-0.076 0.052 0.039 0.938 0.953 0.925 0.875 0.779 0.30** 0.73** -0.09 0.40** 0.43** 0.59** 0.09 0.08 0.46** 0.31** 0.48** 0.86** 0.01 0.03 -0.08 0.91** 160 0.23** 0.01 0.09 0.03 0.58** -0.08 0.91** Table 4.28 Comparison of Structural Models (Continued) Squared multiple correlation BF BI BT ABL BE 0.54 0.55 0.67 0.62 0.74 0.75 0.56 0.73 Notes: - Not applicable, ** Significant at the .001 level BA=Brand awareness, BF=Brand familiarity, PQ=Perceived quality, BI=Brand image, BT=Brand trust, ABL=Attitudinal brand loyalty, BE=Brand equity The squared multiple correlations of brand equity did not indicate significant changes across the three models (P: 0.74, A: 0.75, G: 0.73), with the differences of ±0.01. In other words, the R² of brand equity was proven to have slightly 1% improvement (0.01 X 100%) once the proposed model (P) was re-specified to Aaker model. Interestingly, in P model, the value of squared multiple correlations were found to have greater than 0.5 for brand familiarity, brand image, brand trust, attitudinal brand loyalty, and brand equity. In contrast, A and G models only indicated squared multiple correlations value for brand equity or attitudinal brand loyalty. Based on the arguments as discussed above, the proposed model was considered as an imperative contribution in the Malaysian field of fast food brand equity. This was because it demonstrated more comprehensive causal relationships, good goodness-of-fit indices, consistent structural parameter estimates, and did not significantly different from the Aaker’s (1991) and Gil et al.’s (2007) framework. Moreover, it covered a broader view of squared multiple correlations. 161 4.9 Conclusion A total number of 600 questionnaires were distributed among Malaysian (Marrybrown and 1901 Hotdogs) and foreign (McDonald’s, KFC and Pizza Hut) fast food restaurants. Only 15 surveys were excluded due to incomplete responses. Thus, 585 or 97.50% of respondents were qualified and were used for further analysis. Basically, there were 50.43% male and 49.57% female, which were equally distributed. With respect to ethnic groups, 63.09% were Malays, followed by Chinese (26.15%), Indian (4.96%), and others (5.80%). The final measurement model (CFA21) was over-identified with 254 degree of freedom, and the Goodness-of-Fit was above the recommended value (χ² = 859.593, χ²/df = 3.384, RMSEA = 0.064, SRMR = 0.037, GFI = 0.893, CFI = 0.950, NFI = 0.931, IFI = 0.950, TLI = 0.942, PCLOSE = 0.06), and the p-value associated with chisquare was 0.0001. Besides, CFA21 was proven to meet all the criteria for construct reliability, convergent validity, discriminant validity, and nomological validity. The same set of fit indices of measurement model was used to assess the structural model. The χ² was 917.953 with 263 degrees of freedom (p<0.001) and the normed chi-square was 3.490. The model CFI was 0.946, with a RMSEA of 0.065 and 90% confidence interval of 0.061 to 0.070. The results suggested that the proposed model provided a good overall fit. Out of 12 hypotheses, 9 statements were supported and 3 were rejected due to insignificant statistic. The results of the comparison among the three models (proposed model, Aaker, and Gil et al.) were consistent and the value for standardized structural parameter estimates did not vary dramatically. Moreover, proposed model covered a broader view of squared multiple correlations as compared to previous model. 162 CHAPTER 5 DISCUSSION ON FINDINGS 5.1 Introduction First and foremost, the chapter starts with the discussion on the result of the hypotheses, and each of the hypotheses had been identified with previous studies. Next, the chapter justifies the importance and inclusion of brand familiarity as well as brand trust in this study. It is followed by the identification of causal relationships in the proposed model, which highlights the rational linkage of causal relationships between dimensions of brand equity and overall brand equity. 5.2 Discussion on Hypotheses Results The results of this study predicted the relationship between constructs of consumer-based brand equity, namely perceived quality, brand awareness, brand familiarity, brand image, brand trust, attitudinal brand loyalty and brand equity. There is no causal relationship between brand awareness and perceived quality, yet, there is existence of correlation. The deliberations for each of the hypotheses are stated in Figure 5.1. 163 Notes: a. BA=Brand awareness, PQ=Perceived quality, BF=Band familiarity, BI=Brand image, BT=Brand trust, ABL=Attitudinal brand loyalty, BE=Brand equity b. ** Significant at .05 level Figure 5.1 Results of Proposed Model Hypothesis 1 There is positive correlation between brand awareness and perceived quality (Supported: β = 0.30 t value = 6.04 α = 0.001) The finding confirms the results of previous researchers that the quality as perceived by consumers is positively correlated with the brand awareness (Grewal et al., 1998; Dodds et al., 1991). In the same vein, when consumers are uncertain about a particular brand, the risk as perceived by consumers had increased (Hoeffier & Keller, 2003). 164 For this reason, the awareness or popularity of the brand will definitely drive to better quality as expected by consumers (Erdem & Swait, 1998). Therefore, the positive (negative) result from fast food brand awareness and perceived quality would serve as a helpful (unhelpful) platform to ensure credibility and visibility for each other. Hypothesis 2: The higher the awareness of a brand, the greater the brand familiarity (Supported: β = 0.73 t value = 14.08 α = 0.001) The result of this study is in line with most of the branding research papers and conceptual papers (Alba & Hutchinson, 1987; Cobb-Walgren et al., 1995; D’Souza & Rao, 1995; Gursoy & McCleary, 2004; Reynolds & Olson, 1995). According to Keller (2003), brand awareness is related to the strength of the brand elements such as logo, symbol, character, packaging, slogan and so on, that store in consumers’ memory. For this reason, fast food brand elements instantly processed once the brand was retrieved from consumers’ mind, consequently, the repeated frequency of fast food brand information processing was stored as cognitive representations of knowledge. Hypothesis 3: The higher the awareness of a brand, the greater the brand image (Not Supported: β = -0.09 t value = -1.38 α = 0.17) Other researchers examined the causal relationship between brand awareness and brand image (Angel & Manuel, 2005; Esch et al., 2006; Hoyer & Brown, 1990). Contrast with previous studies, this study indicated the causal relationship between the two constructs was not supported. Hoyer and Brown (1990) stated that brand awareness generated the differences in information processing, and these differences, which were created by brand associations in the consumer’s memory, directly affect brand image. 165 However, some scholars argued that brand awareness was referred to as the level of consumers’ brand exposure (Alba & Hutchinson, 1987; Woodward, 2000). As a result, brand awareness alone was not sufficient to generate different type of associations and attributes that consumers connect to the brand name (Das et al., 2009), and also highlighted the existence of different degrees of cognitive (Frey, 1982) in brand equity formation. Notably, the repeated brand awareness had driven to brand familiarity, which is the number of brand-related experiences, direct and indirect knowledge available to the consumer (Alba & Hutchinson, 1987) before constructing any cognitive brand image. In other words, solely depended on brand awareness was not sufficient to explain the formation of brand image, and the familiarity of brand serves as a vital variable to explain the relationship in between brand awareness and brand image in the Malaysian context of fast food industry. Hypothesis 4: The higher the familiarity of a brand, the greater the brand image (Supported: β = 0.40 t value = 6.37 α = 0.001) This study supported consumers’ formation process of brand image, which is related positively to the extent to which the familiarity of the brand was evidenced, correspond with previous studies (Holden & Vanhuele, 1999; Janiszewski, 1993; Zajonc & Markus; 1982). Therefore, when a consumer was confronted with a familiar fast food brand, he or she felt emotional closeness and confidence. Subsequently, enhance in the association of the brand in consumers’ mind, and positively affected consumers’ image towards the fast food brand. On the other hand, when a consumer was unfamiliar with the fast food brand, he or she was incapable to stimulate the fast food brand because of the lack of knowledge and experience with the brand’s attributes, benefits, and attitudes. 166 Hypothesis 5: The higher the familiarity of a brand, the greater the brand trust (Supported: β = 0.43 t value = 10.96 α = 0.001) This study had supported the hypothesis that higher brand familiarity led to better brand trust, which was line in with previous studies (Campbell & Keller, 2003; Fullerton, 2005; Keller, 1998; Papadopoulou et al., 2001; Sen & Johnson, 1997; Smith & Wheeler, 2002; Zajonc & Markus, 1982). As a result, the increases in fast food brand familiarity through accumulated customer experiences and greater amount of time spent in processing brand information were not only created better knowledge structure, but also build up confidence and trust for the fast food brand. Hypothesis 6: The higher the perceived quality of a brand, the greater the brand image (Supported: β = 0.59 t value = 12.65 α = 0.001) According to Keller (1993), good evaluation of perceived quality had bought about customers to have strength, favorability, or uniqueness type of brand association. Again, the empirical result of this study confirmed the above statement, which corresponded with Kayaman and Arasli’s (2007) hospitality study. Therefore, the perception of quality served as an important antecedent of brand image creation in the Malaysian context of fast food industry. 167 Hypothesis 7: The higher the perceived quality of a brand, the greater the brand trust (Not Supported: β = 0.09 t value = 1.94 α = 0.06) Remarkably, the perception of good quality was not positively affected by brand trust. The result revealed a contradict result to Papadopoulou et al.’s (2001) online study. Possibly, the perceived quality in impersonal business was critically evaluated by consumers, but did not apply in interpersonal business, such as fast food business. Furthermore, brand trust was classified as affective character, which referred physiological responses, such as positive moods, feelings, and emotional responses. Hence, the establishment of bond between consumers and the fast food brand trust required greater association and cognitive representations of consumers’ knowledge, rather than the perception of quality. Hypothesis 8: The higher the perceived quality of a brand, the greater the attitudinal brand loyalty (Not Supported: β = 0.08 t value = 1.84 α = 0.07) The empirical result highlighted that perceived quality did not statistically cause attitudinal brand loyalty in the context of fast food industry. Nevertheless, this result was in line with some of the previous studies (Aydin & Özer, 2005; Gil et al., 2007; Tong & Hawley, 2009). This could be further explained that attitudinal brand loyalty had been considered as a conative construct, while perceived quality was considered as a cognitive construct, based on arguments of cognitive-affective-conative hierarchical model (Chiou et al., 2002). Therefore, in fast food context, perceived quality could only drive an effect on attitudinal brand loyalty through affective construct(s). Affective construct would serve as the mediating variable, referring to the result from affective component of attitude, such as “emotional” or “feeling” responses (Lavidge & Steiner, 1961). 168 Hypothesis 9: The higher the image of a brand, the greater the brand trust (Supported: β = 0.46 t value = 8.49 α = 0.001) Next, this study had confirmed that brand image had lead to higher level of trust as perceived by consumers. The result was in conjunction with online study (Esch et al., 2006; Yoon, 2002), hotel study (Back, 2005; Kandampully & Hu, 2007; Kandampully & Suharanto, 2000), financial study (Flavián et al., 2006), as well as restaurant study (Lee, Park, Park, Lee & Kwon, 2005). As a result, the existence of fast food brand image was considered as vital criteria for the development of brand trust. Hypothesis 10: The higher the image of a brand, the greater the attitudinal brand loyalty (Supported: β = 0.31 t value = 5.00 α = 0.001) The result supported that brand image was one of the causes for attitudinal brand loyalty, in line with previous studies (Back, 2005; Flavián et al., 2006; Kandampully & Suhartanto, 2000; Kandampully & Hu, 2007). In addition to that, current result served as an important explanation to identify the relationship between brand image and attitudinal brand loyalty, based on the theory of cognitive-affectiveconative (Lavidge & Steiner, 1961). As discussed in the literature review, brand image was classified as both cognitive and affective characters, while attitudinal brand loyalty was considered as conative construct. Therefore, the image of fast food brand could be classified an essential predictor for the formation of attitudinal brand loyalty. 169 Hypothesis 11: The higher the trust of a brand, the greater the attitudinal brand loyalty (Supported: β = 0.48 t value = 9.43 α = 0.001) In this study, brand trust had been recognized as a prominent variable that had led to long-term relationship with customers, which affected attitudinal brand loyalty in a positive way. The empirical result was consistent with most of the previous studies (Chiou & Droge, 2006; Flavian et al., 2006; Sichtmann, 2007; Martzler et al., 2008; Rauyruen & Miller, 2007). Therefore, fast food brand trust was the key variable to maintain continuing relationships with customers, and served as an important criterion in forming consumers’ positive behavioral intention, such as the intention to repurchase and to make recommendations to the other party (Lau & Lee, 1999). Hypothesis 12: The higher the attitudinal loyalty of a brand, the greater the brand equity (Supported: β = 0.86 t value = 24.95 α = 0.001) Many studies had proven that brand loyalty had significant effect on brand equity (Baldauf et al., 2003; Gil et al., 2007; Kim & Kim, 2004; Norjaya et al., 2007; Tong & Hawley, 2009; Yoo et al., 2000), this indicated that the essential role of developing brand loyalty in brand equity creation. Therefore, attitudinal brand loyalty could be considered as the most important dimension of brand equity. The result was supported by many researcher findings, which indicated customer loyalty served as the basic for the development of brand equity (e.g. Aaker & Joachimsthaler, 2000; Clarke, 2001; Davis & Dunn, 2002). This was because loyalty had been identified as a favorable attitude, which would lead to the consistency of repurchase behavior towards a brand (Assael, 1992). As a conclusion, the finding ratified the importance of managing loyalty as part of the brand management strategy (Christodoulides & de Chernatony, 2004; O’loughlin, 2006), and it have to be extended to the Malaysian fast food sector. 170 5.3 The Importance of Brand Familiarity and Brand Trust Notes: a. BA=Brand awareness, PQ=Perceived quality, BF=Band familiarity, BI=Brand image, BT=Brand trust, ABL=Attitudinal brand loyalty, BE=Brand equity Figure 5.2 Brand Equity Model – The Exclusion of Brand Familiarity and Brand Trust Referring to Figure 5.1 (p. 164), there were significances in the results for most of the hypotheses which were either related to brand familiarity or brand trust. Turning to Figure 5.2, the model (excluded brand familiarity and brand trust) was indicated a missing link of brand awareness on other brand equity dimensions. Besides, there were only four significant causal effects which existed in the model. Furthermore, there was no variable which was absolutely characterized as affective brand dimensions. By including brand familiarity, the missing link of brand awareness could be justified. For instance, brand awareness contributed significantly on brand familiarity, which showed that the linkage between brand awareness and other variables, such as brand image, brand trust, attitudinal brand loyalty, and brand equity. 171 On the other hand, brand trust was considered important because it was the absolute variable that classified as affective brand dimensions. In addition, there were three significant causal effects could be evidenced in relation to brand trust. Besides, the value of squared multiple correlations for brand familiarity and brand trust were found to have 0.55 and 0.67 respectively, which was greater than 0.50. For these reasons, there was a positive conformity for the inclusion of both additional dimensions in the Malaysian context of fast food industry. 5.4 Identification of Causal Relationships in the Model Notes: a. BA=Brand awareness, PQ=Perceived quality, BF=Band familiarity, BI=Brand image, BT=Brand trust, ABL=Attitudinal brand loyalty, BE=Brand equity b. Red bolded path=Significant at .05 level; Dotted path=Non-significant at .05 level Figure 5.3 The Overview of Causal Relationships in Malaysian Fast Food Industry 172 Referring to Figure 5.3, a rational linkage could be evidenced from the causal relationships among dimensions of brand equity and overall brand equity in the Malaysian context of fast food industry. According to Aaker (1991), brand awareness was a critical factor for brand equity, and the awareness of the brand was the beginning of loyalty. If a customer was aware of a certain brand, there was a higher possibility that the customer would have a favorable image towards the brand (Keller, 1993). However, most of the empirical studies failed to indicate a significant causal effect of brand awareness on brand equity, for instance in online branding (Graebner-Kraeuter, 2002; Rosa & Riquelme, 2008), hotel study (Bailey & Ball, 2006), sportswear market (Tong & Hawley, 2009), and consumer products (Wang et al., 2008). In order to provide further explanation, this study found there were numerous of significant compound paths from brand awareness to brand equity, for instance via brand familiarity, brand image, brand trust and attitudinal brand loyalty. Thus the findings explained the linkages from brand awareness to brand equity could be significantly determined, even though brand awareness did not significantly affect brand equity directly, based on the result from model re-specification as indicated in Aaker and Gil et al. frameworks. As a result, this study showed the possibility of significant indirect effects when directs effects are absent (Rucker, Preacher, Tormala, & Petty, 2011). Subsequently, this study supported brand awareness was a key dimension for fast food brand equity, it had affected consumer decision making by influencing the formation and strength of other brand equity dimensions, which drove to brand equity indirectly via other dimensions. This study provided explanation for the non-significant causal effect of perceived quality on brand loyalty (Gil et al., 2007) and brand equity (Tong & Hawley, 2009). Referring to Gil et al. (2007) and Tong and Hawley (2009), they did not investigate the causal effect of perceived quality on other brand equity dimensions. Consequently, there was a missing link of perceived quality in their research model. By establishing the causal relationships on greater numbers of brand equity dimensions, the results indicated brand image had been considered as a construct preceded by perceived quality. This could be further explained by the theory of cognitive-affective- 173 conative, that is, perceived quality was considered as a cognitive construct which resulted in affective response towards the brand. This affective response had determined consumer behavior, and lead to product purchase and brand loyalty. Therefore, in the Malaysian fast food industry, perceived quality would only have effect on attitudinal brand loyalty and overall brand equity when there was existence of affective responses towards the brand, such as the subsistence of affective brand image. The familiarity of brand names could create a favorable brand image which in the long run led to creation of brand image and brand trust. This was because consumers were likely to buy a certain product or brand that had a favorable brand image (Keller, 1998). Accordingly, the familiarity of fast food brand convinced consumers in term of first brand that appeared in their minds from many existing brand options in a particular fast food category. Furthermore, greater brand familiarity had caused consumers to have greater trust due to higher confidence towards the fast food brand. It included a sense of reduced anxiety, faith in the provider, reduced perceptions of risk, and knowing what to expect. In addition, this study also provided evidences for brand image in retaining brand trust and attitudinal brand loyalty in the Malaysian context of fast food industry. The combination of the favorability, strength, and uniqueness of fast food brand image had led to greater affective reactions and less likely to change to a competitor’s brand (Bowen & Shoemaker, 1998). Thus, it highlighted brand image as a vital antecedent of brand trust and attitudinal brand loyalty in the context of fast food branding. 174 Importantly, trust had a positive impact and also was a key determinant of the relationship commitment (Morgan & Hunt, 1994). This commitment was directly proportionate to the consumers’ level of affect, or in general terms, it was based on how much the customer “like” the service provider (Oliver, 1999). When consumers were affectively loyal, it became much more difficult for competitors to enact switching behaviors through counter-argumentation (Oliver, 1997). Therefore, the trustworthiness of fast food brand had contributed to the most significant causal effect on attitudinal brand loyalty. It also served as an imperative variable in developing the linkage between the brand equity dimensions, especially with attitudinal brand loyalty. As a conclusion, most of the dimensions of brand equity had not influenced brand equity directly in the Malaysian context of fast food industry. Attitudinal brand loyalty was the only dimension that had driven brand equity, which was considered as affirmative attachment or commitment between consumers and the fast food brands. Lastly, based on the identified causal relationships, the findings highlighted a sequential process of brand equity formation, which was further explained by the hierarchy-of-effect theory. 5.5 Conclusion The proposed model supported the premise that brand awareness and perceived quality were necessary steps to create brand equity in the Malaysian context of fast food industry. In addition to that, both brand familiarity and brand trust served as essential variables in the model. By including brand familiarity, the missing link of brand awareness was justified as it showed the linkage between brand awareness and other dimensions. Brand trust was considered important because it was the absolute variable that was classified as an affective character. Overall, this study presented a comprehensive set of causal relationships among the dimension of brand equity. Consequently, it highlighted numerous of compound paths that existed in the model. 175 CHAPTER 6 CONCLUSION AND RECOMMENDATION 6.1 Introduction First and foremost, the chapter starts with the discussion on the research objectives. Basically, it highlights the relevancy between the findings of this study and research objectives as discussed in Chapter 1. Next, the chapter discusses the significant contributions of this study in both academician and practitioners (fast food managers) area. The chapter explains the interpretation of consumer-based brand equity model in the Malaysian context of fast food industry, which indicates the logical explanation of proposed model with the existing marketing theory such as hierarchy-of-effects theory, Gil et al.’s (2007), and Aaker’s (1991) brand equity theory. Remarkably, this study illustrates a practical 4 step brand equity creation for fast food entrepreneurs, which was derived on the model of this study. Besides, it also included the usefulness of these research findings in formulating Malaysian government assistance programmes. Last but not least, the limitations and recommendations of this study is also presented carefully. 176 6.2 Discussion on Objectives Objective 1: To examine brand familiarity as the additional dimension of consumerbased brand equity in the Malaysian context of fast food industry Brand familiarity was related positively to the extent to which awareness was evidence in the brand. Besides, it generated strong effect on both brand image and brand trust. In addition, it served as a vital variable in explaining the relationships between brand awareness and other brand equity dimensions as well as overall brand equity. For instance, the results from the current study indicated that brand familiarity (direct effect) and brand awareness (via brand familiarity) significantly contributed to brand image. Furthermore, brand familiarity had high value of squared multiple correlations (R²=0.54). Thus, it provided strong positive agreement for research question 1: “Does brand familiarity serve as additional dimensions of consumer-based brand equity in the Malaysian context of fast food industry?” Objective 2: To examine brand trust as the additional dimension of consumer-based brand equity in the Malaysian context of fast food industry In the Malaysian fast food industry, there were only brand image (β=0.31) and brand trust (β=0.48) which had significantly influenced attitudinal brand loyalty. Brand trust had contributed higher coefficient beta (β) value than brand image, specifically, the trust of fast food brand was considered as the most critical affective feeling as perceived by Malaysian consumers in brand creation. Therefore, the existence of brand trust provided a better understanding in explaining the relationships among brand equity dimensions. Furthermore, brand trust had high value of squared multiple correlations (R²=0.67). As a result, there was positive conformity for the research question 2: “Does brand trust serve as additional dimensions of consumer-based brand equity in the Malaysian context of fast food industry?” 177 Objective 3: To investigate the causal relationships among dimensions of consumerbased brand equity in the Malaysian context of fast food industry The third objective of this study was to investigate the causal relationships among dimensions of consumer-based brand equity in the Malaysian context of fast food industry. The proposed model was empirically investigated within the context of fast food industry, along with 10 hypotheses that related to causal effects, were tested simultaneously. The results highlighted that there were 7 significant causal effects which existed among brand equity dimensions. Thus, the findings of this study presented an important answer for research question 3. Indeed, causal relationships existed among brand equity dimensions, and interestingly, attitudinal brand equity served as the only variable that linked between brand equity dimensions and overall brand equity in the Malaysian context of fast food industry. Practically, the result showed that the creation of brand equity was not an easy task; it had fulfilled the sequential order of brand elements (cognitive-affectiveconative). Theoretically, the findings supported the existence of causal relationships among brand equity dimensions. It also highlighted the potential indirect influence of brand equity dimensions (e.g. brand awareness and perceived quality) on overall brand equity via other variable(s). This could be supported by the causal effects which were identified in model simultaneously. Importantly, there was no missing link of causal effects among the brand equity dimensions. Therefore, the findings provided meaningful explanation for both academician and fast food manager. 178 Objective 4: To develop consumer-based brand equity model in the Malaysian context of fast food industry Overall, the proposed consumer-based brand equity model was tested using structural equation modeling (SEM), which suggested an acceptable Goodness-of-fit statistics (GOF). Besides, it also satisfied a series of reliability and validity assessments for measurement as well as structural model. In addition to that, the model showed greater numbers of brand equity dimensions. The inclusion of brand familiarity and brand trust had not been investigated by most of the previous researchers (Tong & Hawley, 2009; Rosa & Riquelme, 2008; Gil et al., 2007; Angel & Manuel, 2005; Yoo et al., 2000). Remarkably, the squared multiple correlation (R²) of brand equity dimensions, such as brand familiarity, brand image, brand trust, and attitudinal brand loyalty were all above 0.50 value. Besides, the R² of overall brand equity was 0.74, which served as additional supporting evidence for the development of this model. In addition to that, the present results supported the proposed model based on psychological consumer response, explaining the implication of cognitive-affective-conative in consumer-based brand equity. Thus, the model in this study provided a vital road map for the implication of branding strategy in the Malaysian fast food industry. Apart from that, the findings further presented in 4 distinctive steps (see managerial implication), for the purpose to serve the best understanding of implication among Malaysian fast food managers. Therefore, the development of model served in answering the research question number 4: “How do we develop consumer-based brand equity model in the Malaysian context of fast food industry?” 179 6.3 Contribution of Study 6.3.1 Brand Image Measurements From an academic standpoint, the measurement of brand image had been specified to a product category (Dobni & Zinkhan, 1990; Kim & Kim, 2005; Low & Lamb Jr., 2000). Therefore, this study had developed the measurements of fast food brand image, which assisted in predicting the future performance of fast food brands in market place, following consumer perceptions. A total number of 13 observed variables were identified in this study. The result corresponded to the fact that consumers’ knowledge about a place and environment were characterized as cognitive and affective quality (Burgess, 1978; Hanyu, 1993; Genereux et al., 1983, 1993; Lynch, 1960; Proshonsky et al., 1983; Russel & Pratt, 1980; Russel et al., 1989). As a result, the cognitive and affective characters of observed variables are presented in Table 6.1. Table 6.1 Cognitive and Affective Brand Image Measurements Cognitive Character Affective Character • Delicious • Prompt service • Free WiFi • Good customer service • Variety of choices • Good value for money • Convenient • Widely distributed • Long history • Good dining environment (Relaxing & Exciting) • Pleasant (Pleasure) • A place for social gathering (Arousal) • Easy (Pleasure) 180 6.3.2 A Sequential Process of Brand Equity Formation The main contribution of this research was the development of a theoretical model which identified the causal relationships among brand equity dimensions within Malaysian fast food context. Even though several other research were conducted on brand equity framework in the consumer-goods industry (Norjaya et al., 2007), banking industry (Norzalita & Norjaya, 2010), entrepreneur perspective (Zainuddin et al., 2009), small to medium-sized enterprises (Maznah & Mohd Noor, 2010), but there was lack of research that had been done relating to Malaysian fast food industries. The present study had applied Gil et al.’s (2007) brand equity model into fast food context and proposed a modified model that was meaningful, both conceptually and statistically. Consequently, this research extended the understanding of consumerbased brand equity phenomena and its measurement, by exploring the sequential relationships between the dimensions of brand equity, along with the enlightenment of Lavidge and Steiner’s (1961) cognitive-affective-conative. The model of this study was extended to consumers’ response, which was highly related to psychological-based approaches associated with the brand information (Aaker, 1991; Keller, 1993; Loken & Roedder, 1993). The conceptualization of consumers’ response (attitude) toward the brand had incorporated cognitive, affective, and conative components, which were extremely similar to the interpretation given by some scholars to the term brand equity (Grimm, 2005). Referring to the current model, it was identified with strong synchronous connections among cognitive-affectiveconative, and also had provided a non-missing link of causal effects model among brand equity dimensions. In other words, this study was successfully extended the existing brand equity framework by adopting a sequential brand view of each consumers response phase. 181 This study had classified the brand equity dimensions into three different brand phases, corresponding to Lavidge and Steiner’s (1961) hierarchy-of-effect theory. Notably, perceived quality, brand awareness, brand familiarity, and cognitive brand image were considered as cognitive phase, which was related to knowledge. In other words, it referred to the information, evaluation, and beliefs that were held by consumers towards the brand (Lavidge & Steiner, 1961). Recently, Grimm (2005) stated that there was overlapping of attitude components (cognitive and affective) in relation to the brand knowledge presented in the paper of Keller (1993). Therefore, the product attribute was consistent with the operationalization of perceived quality and cognitive brand image, while the experiential benefits had corresponded to affective brand image and brand trust that was used in this study (Keller, 1993). As a result, it was relevant to present brand image as both cognitive and affective characters in this model, which was in line with Keller’s conceptualization of brand image. Moreover, in most of the branding discussions, consumer behavior and psychology had appeared to suggest the affective and emotional usually stemmed from cognitive evaluation (Oliver, 1997; Franzen & Bouwman, 2001). In other words, cognition appeared first and emotion second. For example, Franzen and Bouwman (2001, p. 32) stated “it is often assumed that emotional reactions always stem from cognitive evaluation”. This could be evidenced in the affective phase of the model, referring affective brand image and brand trust to feelings, moods, or emotional responses towards brands that were measured by collecting verbal reports or by physiological responses (Lavidge & Steiner, 1961). Apart from that, affection action also was judged as an important response that could not be overlooked. This was because affective reaction was considered as first reactions, which occurred quickly and automatically, consequently led to information processing and judgments about the objects, activities, and other stimuli with a direct and primary role in motivating behavior (Slovic et al., 2002; Zajonc, 1980, 2000). Some researchers supported that affective response was a direct and primary role in behavior (LeDoux, 1996; Slovic, Finucane, Peters & MacGregor, 2002; Zajonc, 1980). 182 Besides, affective evaluation had taken place without conscious stimulus recognition, and as a key antecedent of current and future purchases (Esch et al., 2006). Therefore, affective brand image and brand trust were essential and played as important role in determining the existence of conative brand phase in the fast food brand equity creation. As a conclusion, this model viewed brand equity as a three sequential brand phases, thus the subsistence of cognitive and affective constructs served as prerequisite for attitudinal brand loyalty and brand equity (conative character). The model was in line with Aaker’s (1996) implication that product related characteristics (cognitive elements) could be primary drivers of brand personality. In other words, cognitive thinking could have taken place first (through functional/utilitarian reason) which then led to emotional or affective reaction. This in turn had driven to the overall satisfaction and thus led to individual’s commitment to purchase the brand (conative response) and subsequently, actual behavior (Oliver, 1993). Interestingly, albeit the dimensions of brand equity was classified into three brand phases, the model specified that the dimension(s) from a particular brand phase (cognitive dimension - e.g. brand awareness) did not necessary indicate a significant direct relationship for the next level of brand phase (affective dimension – e.g. brand trust). This can be further explained by the different degrees of cognitive (Frey, 1982), affective (Oliver, 1993) and conative (Reitan & Wolfson, 2000). 183 6.3.3 The Role Brand Familiarity and Brand Trust in Malaysian Fast Food Industry The development of consumer-based brand equity in Malaysian fast food industry is a long-term process; it reflects to the different phases of brand character, such as cognitive, affective and conative. It also involves greater numbers of brand equity dimensions, such as brand familiarity and brand trust, which might not play important roles in other industry. This study is consistent with the observation of Christodoulides and de Chernatony (2010, p. 61), “a brand equity monitor should incorporate dimensions that drive value within the specific industry.” For instance, brand familiarity and brand trust were proven to contribute significantly in the model as the inclusion had provided a better understanding of consumer response towards the fast food brands. This could be further explained by both of the dimensions appeared to be far greater for the situation where the consumer looked for a simple rule for decision-making (Batra & Ray, 1985). For instance, brand familiarity served as a source of pleasure and reassurance, which transformed fast food into “comfort foods” (Schlosser, 2002). Thus, it not only emphasized on the total time spent processing information about the brand (Baker et al., 1986), but also indicated the direct and indirect knowledge available to the consumer (Alba & Hutchinson, 1987). On the other hand, brand trust was created from an exchange environment in which the fast food brands provided consistent services to its customers across different outlets (Tan et al., 2011). Therefore, a feeling of security held by the consumer in his or her interaction with the fast food brand, such that it was based on the perceptions that the brand was reliable and responsible for the interest and welfare of the consumer (Morgan & Hunt, 1994). 184 6.3.4 Consumer-based Brand Equity Model in Malaysian Fast Food Industry This study had classified perceived quality, brand awareness, brand familiarity, and cognitive brand image as cognitive characters. On the other hand, affective brand image and brand trust were categorized as affective characters, while attitudinal brand loyalty and brand equity were grouped into conative characters. This model states that both perceived quality and brand awareness were the initial stage of brand building in consumer-based context (Alba & Hutchinson, 1987; Hoyer & Brown, 1990). As noted in literature review, perceived quality was not the actual quality but the overall customer’s perception of the brand (Zeithaml, 1988). Positive or negative perceived quality incurred when consumers cognitively processed the available knowledge between a particular brands with others. On the other hand, brand awareness was related to capability of prospect buyer to recognize or recall a particular brand (Aaker, 1991). It could be determined by the ability of potential buyers who successfully associate a brand with its product category. Thus, perceived quality and brand awareness had been referred to as the simplest level of cognitive response that existed in the knowledge of consumers for the brand (Alba & Hutchinson, 1987; Hoyer & Brown, 1990). For these reasons, it had not made sense neither would cause the other. It could be further explained that the awareness of fast food brand was not the prerequisite for the creation of perceived quality and vice versa. Positive perceived quality could be existed when consumers previously had grateful experiences with the fast food brand or better perception for a higher price brand. On the other side, brand awareness could be referred to the recognition of the fast food brand character, such as the brand name, McDonald’s logo, KFC symbol, or even 1901 Hot Dogs tagline; it did not necessary related to the quality of the fast food brand. 185 Remarkably, the awareness of fast food brand alone was not sufficient in providing the brand image hold in the consumer’s memory. This was because the creation of brand image in term of mentality resulted from the brand strength, uniqueness, favorability, experience, and strong perception of the consumer through coordination and stimulation (Keller, 2003). Furthermore, image of fast food brand required ideas, feelings, attitudes, mental constructs, understandings or expectations that from the brand in the memory of consumers, in other words, it involved greater association of consumers’ memory than just recalling or recognizing. Apart from that, the awareness of fast food brand was not considered as increasing consumers’ confidence level in the uncertain environment. However, consumers had felt comfortable on trusted brand because the brand had long-term relationships with them (Chiou & Droge, 2006; Flavián et al., 2006; Sichtmann, 2007; Matzler et al., 2008). Therefore, the familiarity of fast food brand was essential, as it enhanced consumers’ formation process of brand image (Holden & Vanhuele, 1999; Janiszewski, 1993; Zajonc & Markus; 1982) and feelings of greater trust between the restaurant brand and the consumers (Lee et al, 2005). These were because brand familiarity had driven to a sense of reduced anxiety, faith in the provider, reduced perceptions of risk, and consumers knew what to expect directly. For these reasons, brand familiarity served as an important role in enlightening the relationships between brand awareness and other brand equity dimensions in the Malaysian context of fast food industry. Perceived quality required greater information processing as it focused on explaining how consumers cognitively had established an overall brand impression, before reaching a fast food consumption choice. Perceived quality was involved in the perception of brand’s quality and superiority. The perception could be based on past experience (Dabholkar, 1995; Donovan et al. 1994) and affective quality signals in marketing efforts (Grönroos, 1984). Thus perceived quality was sufficient for the creation of brand image as it involved consumers in developing, maintaining, and giving meaning to the influence of personal experience of the stimulated brands. 186 Brand image, in particular, exercised a strong direct influence on brand trust and attitudinal brand loyalty. The findings were line with studies which investigated the effect of brand image on customer’s trust (Esch et al., 2006; Flavián et al., 2006; Yoon, 2002) and brand loyalty (Aaker, 1996; Back, 2005; Kandampully & Suhartanto, 2000; Kandampully & Hu, 2007; Keller, 1998). Therefore, the image of fast food brand was considered important because it served as image drivers, such as the association between the fast food brand and intangible symbolic benefits as perceived by consumers, which satisfied consumers in term on social class, self-emotional, and any other perception of needs (Keller, 1993). In addition, the image drivers were also extended to lifestyle, trustworthiness, and self-concept (Neal & Bathe, 1997). Besides brand image, brand trust also contributed significantly on attitudinal brand loyalty, which corresponding to most of the previous findings (Chaudhuri & Holbrook, 2001; Chiou & Droge, 2006; Flavián et al., 2006; Harris & Goode, 2004; Matzler et al., 2008; Morgan & Hunt, 1994; Mayer et al., 1995; Sichtmann, 2007). Specifically, this study defined brand trust as positive emotional feeling and affective reactions that results from the trusted brand. Therefore, it presented an emotion-driven aspect (affective character) of long-term relational exchanged between fast food brands and consumers, rather than the utilitarian value (cognitive character) of the brands. Importantly, attitudinal brand loyalty played as a key variable for explicating the relationships between other dimensions and brand equity. In other words, fast food brand equity would not exist when there was no attitudinal brand loyalty. Nevertheless, when there was absence of brands’ affective reactions, attractiveness, aesthetics, or signals of benevolence (affective sense of brand trust), consumers would less likely in repeat purchase intention, recommendation to others, or willingness to pay a price premium. Thus, the trustworthiness of fast food brand served as a vital antecedent for the development of attitudinal brand loyalty, which ultimately drove to overall brand loyalty. 187 6.4 Managerial Implication 6.4.1 Brand Image Measurements The brand image measurements provided an opportunity for fast food managers to improve specified brand image strategies. Specifically, the managers of fast food restaurant chains can utilize the brand image scales from this study, as a diagnostic instrument, to examine whether the consumers’ associations towards their restaurants are in line with the brand’s mission, vision and goals. By identifying the consumers’ association of brand image towards their brand, managers can compare and differentiate their brands with competing brands from the similar industry. 6.4.2 Steps of Brand Equity Creation in Malaysian Fast Food Industry The model of this study had provided a useful and applicable guideline for the development of Malaysian fast food brands. Importantly, it indicated the brand phase, which was related to different phase of consumers’ response towards the fast food brands. Thus, it was highly relevant for the implication of marketing research initiatives, branding strategy, and brand tracking. The consumer-based brand equity model was simplified into four steps as illustrated in Figure 6.1. It was identified into step processes as consumers would not jump into attitudinal brand loyalty or brand equity unless there were existences of brand cognition (brand awareness, perceived quality, brand familiarity, and cognitive brand image) and brand affect (affective brand image and brand trust). For this reason, this study had highlighted that each steps was contingent upon the successful completion of previous step, in line with “branding ladder” as introduced by Keller (2001). 188 Notes: BA=Brand awareness, PQ=Perceived quality, BF=Band familiarity, BI=Brand image, BT=Brand trust, ABL=Attitudinal brand loyalty, BE=Brand equity Figure 6.1 Steps of Brand Equity Creation in Malaysian Fast Food Industry Figure 6.1 showed that the creation of consumer-based brand equity involved four differentiated steps. Remarkably, each of the preceding steps served as a prerequisite for the next successful marketing effort. In addition to that, step 1 and step 2 revealed to have impacts on step 4 as identified in compound paths. Therefore, to create a sustainable and strong brand name in Malaysian fast food industry, practitioners had to take into consideration that there was no “shortcut”; each of the steps had to be created and brand building process had be monitored consistently. 189 Step 1: Establishing brand awareness, relatively relevant to a specific product class The first step is to make sure that fast food managers had established the most relevant brand input in consumers’ mind; which clearly had identified the product or service categories that was offered, as compared to other competitors. Therefore, the identification of the brand position and category served as a necessity and crucial marketing plan in creating brand equity. Accordingly, Keller’s (1998) consumer categorization processes was employed as the technique in registering a brand in the consumers’ memory. Table 6.2 presented the general hierarchical fashion of Malaysian fast food industry. Firstly, fast food managers had to decide on which consumer categorization processes had to be targeted for brand awareness programs, such as product class information, product category and product type information. Next, it was followed by the design of programs which highlighted the visibility of brand information as compared to brands. Consumers had on top-of-mind and sufficient mind share of a particular fast food brand when there was a high relevancy of consumer categorization processes along with the marketing efforts. As shown in the Figure 6.1, the brand awareness influenced brand equity and other dimensions indirectly, in other words, whatever efforts that had been executed in increasing the brand awareness had to be in line with the objective of overall brand equity, for instance fast food category, brand meaning, brand name, logo, symbol, tagline, and so forth. In addition to that, the design of brand awareness programs had to be focused on satisfying consumers’ affective needs. That is, fast food managers had to illustrate the satisfaction on affective response, such as pleasure, relax, excitement, and arousal, social class, self-emotional, lifestyle, trustworthiness, and self-concept instead of focusing on food quality. 190 Table 6.2 Consumer Categorization Processes on Fast Food Brands Product Class Information Product Category Brand Information Product Type Information McD All Day Fried/Baked Non-Fried Dessert Beverage Breakfast Fried/Baked Non-Fried Beverage Note: McD=McDonald’s, Apple Pie Breadstick Burger Chicken Chop Chicken Wing Fish and Chips French Fried Fried Chicken Garlic Bread Nuggets Pizza Popcorn Chicken Potato Wages Toasted Twister Coleslaw Hot Dogs Mashed potato Oriental Rice Pasta Porridge Salad Soup Ice Cream Blended Ice Cream Egg Tart Pudding Shake Carbonated Soft Drink Float Drink Fruit Juice Hot Drink Iced Blended Drink Mock tails Egg Bun Hash Brown Pancake Sausage Patty Scrambled Egg Toasted Twister Porridge Hot Drink KFC=Kentucky Mb=Marrybrown, 1901=1901 Hot Dogs 191 Fried KFC Ph Mb 1901 √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ √ Chicken, Ph=Pizza Hut, These could be supported in cognitive psychology, as memory was considered very durable (Keller, 1993). Things that were stored in memory tended to stay there for a long time (brand category, brand meaning, brand name, logo, symbol, tagline, illustration of affective response). Besides, brand awareness had to be the most important use of heuristics (the simplifying strategies) where consumers tended to choose a well-known brand as it facilitated the choice process. As a result, consumers displayed a tendency to accept more advertising repetition by a familiar brand than from an unknown or unfamiliar brand. Thus, pioneer brands always had tremendous advantages when it came to conquer the permanent positive memory codes. Therefore, building the highest possible degree of brand awareness had been based on targeted category of new fast food brands as it ensured the successfulness of marketing efforts. Step 2: Creating constructive brand cognition Basically, there are three dimensions that needed to be focused by fast food managers, namely brand familiarity, perceived quality, and cognitive brand image. Stage 2 served as a role in creating constructive brand cognition. Fast food managers had to provide not only positive, but constructive inputs for consumers regarding their fast food information. According to Heding et al. (2009), memory was activated by a sensory input and thus would start the spreading activities. Thereby, knowledge was retrieved from memory; knowledge in memory consisted of nodes and was structured into associative networks, where nodes are the stored information connected by link in associative networks (Heding et al., 2009). The nodes vary in strength; some associations are stronger than others. Subsequently, fast food managers had to “supply” a constructive set of input about their brands for the purpose of creating a meaningful set of associative networks. The main reason was to avoid the fast food brands from establishing an indistinguishable brand meaning, consequently which could lead to the difficulty in creating strength, favorability, and uniqueness of their brands as associated by consumers. 192 As discussed previously, the awareness of fast food brands transformed brand familiarity before it was sufficient for further association in consumers’ mind. In other words, stage 1 served as the most important stage to identify the level of brand familiarity that existed in consumer’s memory. As a result, there was necessary for fast food managers to maintain the consistency of brand exposure from time to time, this was because in cognitive consumer research, repeated exposure to an advertising message was considered very important (Baker et al., 1986). Furthermore, the exposure should be designed in a constructive, understandable and meaningful flow of information with respect to the brand, which implicitly drove to the enhancement of consumers’ association on brand image and brand trust. Positive quality perception served as a very important role in establishing a strong brand image. This was because positive perception formed a strong interactive relationship with customers. In Malaysian fast food industry, managers had to be cautious on the appraisal of service performance as consumers had different expectation on the nature operation, for instance prompt services, handling complaints, individual attention, and willingness to help. As a result, the effectiveness and efficiency of services quality was an important aspect (Lane & Dupre, 1997). Apart from that, Gregoire and Spears (2007) stated that fast food, also referred to as limitedservice, limited menu or quick service which was designed to provide a limited number of food items to a customer in a relatively short period of time. Therefore, perceived quality could be created by providing fast service with the minimum of waiting time. Interestingly, food quality and restaurants appearance were associated as brand image instead of perceived quality. As a result, fast food managers emphasized on variety of choices, good value for money, and good dining environment, for the purpose of creating strong brand image. Besides maintaining the food quality; fast food managers also had to consider the consumers’ willingness to pay for the food when compared to other fast food brands. In addition to that, fast food managers had to focus on the concept design of “good dining environment” for the store renovation. There had been no value added if the expenditure only focused on the physical appearance. In 193 this stage, fast food managers had to make sure consumers could associate their brands into cohesive and meaningful mental networks, which corresponded to the “spreading activity” of the brand node as explained by Heding et al. (2009). An example of spreading activity might be the word “McDonald’s”. The retrieval of the node McDonald’s triggers a spreading activity that potentially could look like Figure 6.2. This association could continue in all directions until they had lost relevance for the node McDonald’s. Note: BA=Brand awareness, PQ=Perceived quality, BF=Band familiarity, BI=Brand image. Source: Adopted and modified Aaker’s (1996) mental network Figure 6.2 Mental Network of McDonald’s 194 Step 3: Eliciting encouraging brand affect In this step, fast food managers focused on affective brand image and brand trust. According to Eagly and Chaiken (1993), affective responses ranged from extremely positive to extremely negative and could be located on an evaluative dimension of meaning. In addition to that, when consumers are affectively loyal, it becomes much more difficult for competitors to enact switching behaviors through counter-argumentation (Oliver, 1999). In other words, it was highlighted that a fast food brand had been generally (rarely) accepted by consumers when there was existence of positive (negative) brand affect. Step 3 was highly depended on step 1 and step 2 (flow of effects). If there were no strong fundamentals of step 1 and step 2, for instance a consumer was not aware and familiar about brand A, or did not have any idea about the quality of brand A. Undoubtedly, the consumer had not associated a clear image and trust value of the brand. However, step 3 was considered important as it transformed beliefs and knowledge about the fast food brand to affective quality in an encouraging way. The main role of Step 3 was to encourage consumers to have brand affect proactively. Affective response could be motivated by illustrating the superiority of affective feeling, such as arousing, pleasant, exciting and relaxing as defined by Russell (1980). For instance, McDonald’s introduced “I’m lovin’ it” campaign in year 2003, together with this campaign, various contests and programs had been carried out to encourage the brand affect of McDonald’s. Thus, in order to have a great affective brand image, fast food managers could have planned for a long-term theme campaign, along with the campaign title; sub-topic could be launched to proactively encourage affective response of consumers. Besides, fast food managers had to ensure that there were high consistency of brand reliability, credibility, operational, and serviceability across different outlets as these had contributed to the creation of affective brand image and brand trust. 195 Step 4: Forming longevity brand conation The last step was the most critical and crucial step for a creation of fast food brand equity. According to Kotler, Keller, Ang, Leong and Tan (2009), acquired new customers can cost five times more than the costs involved in satisfying and retaining current customers. When a consumer was classified as attitudinal loyalty, he or she had exhibited a brand-specific commitment (Oliver, 1999). Attitudinal brand loyalty existed as formation stems from an affirmative attachment and commitment between consumers and brand. Subsequently, this attitude, in turn, occurred from the coincidence between the consumers’ preferences and the brand. The attitudinal brand loyalty and brand equity (brand conation) could be formed by increasing the longevity of the relationship between consumers and the brand. That is, the more involved the brand was with a consumer, the more likely the brand was to stick around with him/her. Consequently, the relationship between the brand and the consumer could be incessantly retained from time to time, along with efforts from step 1 to 3. For brand managers, focusing on brand image and awareness was usually seen as central to the success of marketing campaigns. However, the creation of brand equity required beyond brand image and brand awareness, which in line with Esch et al. (2006). As indicated by Keller’s (2001) branding ladder, relationship was the key for long-term brand success. Therefore, customer loyalty programs such as frequency programs, club marketing programs or gift card programs had been based on the element of longevity, focused on long-term relationship between the fast food brand and consumers. Fast food managers had designed loyalty programs based on the brand relationship quality as recommended by Fournier (1998), namely love/passion, selfconnection, commitment, interdependence, intimacy, and brand partner quality. These six facets were identified as influencing the durability and quality of the relationship, as it illustrated the characteristic of the human relationships, and the way that connected the brand with the identity of the consumers’ live experience (Heding et al., 2009). 196 6.4.3 Formulation of Government Assistance Programmes There were numerous numbers of government assistance programmes which had been conducted by the Ministry of Domestic Trade, Co-operative and Consumerism (KPDNKK) and Ministry of International Trade and Industry (MITI) to help the local entrepreneurs to promote their brands (Ministry of Domestic Trade, Cooperative and Consumerism [MDTCC], 2011b). Most of the programmes were based on traditional marketing, such as packaging (Small and Medium Enterprise Corporation Malaysia [SME Corp. Malaysia], 2011b), business management (Ministry of International Trade and Industry [MITI], 2011), financial assistance (Perbadanan Nasional Berhad [PNS], 2011), and collaboration with external parties, for instance Carrefour, Giant, Jusco, Mydin, Tesco, The Store, Sunshine and Limkokwing University of Creative Technology (SME Corp. Malaysia, 2011a; MDTCC, 2011a). In other words, the nature of the Malaysian government assistance programmes were focused on providing advisory services, market access, infrastructure facilities, financial assistance, and business and networking opportunities (Performance Management & Delivery Unit [Pemandu], 2012). Nevertheless, educating entrepreneurial among existing entrepreneurs and future entrepreneurs was critical because knowledge was the most valuable resources to achieve sustainable competitive advantage (Akio, 2005; Alvarez & Busenitz, 2001; Foss, Klein, Kor & Mahoney, 2008; Liu, 2006; Mathews, 2002; Ong, Hishamuddin & Yeap, 2010). Therefore, in order to formulate a better government assistance program in the fast food branding, the program should be based on the understanding of consumer-based brand equity model, directed to the development of fundamental knowledge among local entrepreneurs. 197 Table 6.3 Examples of Branding Tools based on Brand Equity Dimensions Brand equity dimensions – Cues Examples of Branding Tool Perceived quality • Rely on 1 or 2 cues that associate with • Total Quality Management (TQM) quality that consumers are looking for • Quality Function Deployment (QFD) • Service quality – SERVQUAL • Supportive culture • Rely on 1 or 2 cues that associate with quality • Quality packaging Brand awareness • Enhancing consumer’s ability to • Coupon discounts retrieve the brand from memory when • Creative packaging given the product category • Events sponsorship • Funny/humor advertising • Logo • Publicity • Road show • Sample • Symbol • Target marketing Brand familiarity • Greater the amount of time to improve • Brand souvenir consumers memory towards the brand • Promotion set meal • Creating consistency • Seasonal promotion/product • Single core product promotion – Anytime • Special collection –Mascot • Tagline Brand image • Indicating favorability, strength, and • Breakfast/lunch/dinner/supper promotion uniqueness of brand associations • Celebrity endorsement • Demonstrating an advantage • Cooperative advertising • Looking to the core identity • Widely distribute • Innovative packaging • Movie/song/drama sponsorship • Standardization of store image • Trade shows • Value-based pricing strategies 198 Table 6.3 Examples of Branding Tools based on Brand Equity Dimensions (Continued) Brand equity dimensions – Cues Examples of Branding Tool Brand trust • Analyzing consumers’ feedback – After • Encouraging consumers’ positive sales service emotional feelings and affective • Customer relationship management reactions (CRM) • Standard operating procedures Attitudinal brand loyalty • Forming long-term commitment and • Customer clubs purchase intention • Database marketing • Frequent-buyer programs • Loyalty segmentation • Refunds/rebates Local fast food entrepreneurs had to equip themselves with the ideology of brand equity creation. Importantly, there were no “shortcut” branding (Keller, 2001; Tan et al., 2011), each of the steps had to be created and brand building process should be monitored consistently (see Figure 6.1). For these reasons, the characteristic for each of the brand equity dimensions had to be communicated clearly. Consequently, they would response to the market changes independently and not have the mindset of depending on the supported facilities from the government. That is, they should aim to become knowledge entrepreneurs and be more proactive to fast food market changes. As a result, local fast food entrepreneurs would have their own blueprint for brand equity creation. This was because they had the ability to identify the antecedents and consequences of brand equity dimensions, thus planed the branding tools which in line with the direction or objective of the whole branding strategy. Besides, these findings also contributed to the Entry Point Projects 5 (EPP 5) of National Key Economic Areas (NKEAs), which increases the standard of professional management among the of local food entrepreneurs by polishing their brand management skills (Pamandu, 2012). 199 For instance, With reference to Table 6.3, several examples of branding tool were identified from the dimensions of consumer-based brand equity. Thus, local entrepreneurs had a better direction for the planning of branding strategy. Importantly, Local fast food entrepreneurs designed their own branding tools, which were in line with the dimensions’ cue. As a conclusion, this study had served as an important input for the formulation of government assistance programmes. It provided a solution for assistance programmes, highlighted alternative approach for the growth of Malaysian fast food brand, which was based on the development of fundamental knowledge among local entrepreneurs. 6.5 Limitation and Recommendation for Future Study Several limitations were recognized in this study, each of the recommendations for future study is illustrated. First, there were a total number of 13 items of brand image which had been identified from preliminary study, but, only 5 observed variables had been used in the proposed model after the purification process. Therefore, in future research, there is a need to cover greater number of observed variables in the model, which could provide a clear definition and operationalization of cognitive and affective brand image in the Malaysian context of fast food industry. Although this study proposed the research model based on extensive reviewed of previous literature and reliable theoretical framework, cross-sectional data might have had limited the detection of causal inferences (Hair et al, 2010). Therefore, a longitudinal study should be designed, which was often used in psychology, involved a series of observations made over long period of time. Future research could explore the possibility of a longitudinal study through repeated observations, and invariance test across different samples should be conducted to make certain the components of measurement model and structural model are remained equivalent. Consequently, it would yield more insightful results than a cross-sectional observation study. 200 Besides, the sample was not chosen at random as the sampling frames of fast food consumer were unknown. As a result, there was an existence of inherent bias in convenience sampling as the sample was unlikely to represent the population being studied. This undermined the findings to make generalizations from this study to the population. Furthermore, the sample was made up of volunteers, and then it was likely to be biased because the volunteers might be actively supporting their views towards the survey. Despite greater variance explained in the full structural model of brand equity compared to previous research, there were still some proportions of the variance which are left unexplained. Beyond cognitive-affective-conative attitude research, there was a need to explore the broader information-processing implications, including the contextual effects (Norris & Colman, 1992; Page, Thorson & Heido, 1990), consumer psychology (Bettman, 1979, 1986) and elaboration likelihood model (Petty & Cacioppo, 1986b). Recently, there had been attempts to understand the interaction process between cognition-affect in branding (Agarwal & Malhotra, 2005; Grimm, 2005). In consumption/satisfaction studies, there could be several possibilities of sequence between cognition and affect. For example, emotion (affect) can appear first and cognition second or vice-versa. In other words, dual processing might have existed (Oliver, 1997; Franzen & Bouwman, 2001), and nonrecursive model could be derived. Even in most of the time, nonrecursive model seemed to have problems with statistical identification (Hair et al., 2010), but we could not have undervalued the justification of consumer psychology. As a result, future research should focus on nonrecursive model with theoretical justified and investigate the relationships simultaneously. 201 Besides, current study did not investigate the indirect effects and mediating variables. A mediating effect was created when a third variable/construct intervenes between two other related constructs (Bacon et al., 1995). Traditionally, Sobel test was conducted for the purpose of measuring mediation or indirect effects as it was very conservation (MacKinnon, Warsi & Dwyer, 1995). However, the proposed model was more meaningful if the indirect effect could be conducted simultaneously in a path diagram. Thus, bootstrapping from Shrout and Bolger (2002) was proposed as this method could involve multiple mediations. In term of moderation effect, numerous consumer-studies have shown that there are indeed differences in terms of cognitive processes as well as behaviors between the two genders (Fisher and Dubé, 2005; Meyers-Levy, 1988, 1989; Meyers-Levy and Maheswaran 1991; Meyers-Levy and Sternthal, 1991). According to Moutinho and Goode (1995), who conducted a study on the automobile industry, males were found to be more loyal toward the automobile brands when it comes to making purchases. On the other hand, Meyers-Levy and Maheswaran (1991) revealed that female consumers paid more detailed attention on brand information compared to their male counterparts, and thus resulting in different levels of brand awareness across gender, based on Selectivity Model (Darley and Smith, 1995; Walsh and Mitchell, 2005; Handlin, 2007). In addition to this, ethnic groups might play as a moderator as Burton (2002) had indicated that ethnic minority market offers significant marketing potential. Besides, Chien (2007) had stated there were variations of brand loyalty, perceived quality, and brand image across the age groups, and educational level was appeared to influence the level of brand awareness. As a result, future study should consider the potential effect of moderating variables in the development of brand equity model, which have not been investigated in this study yet. 202 6.6 Conclusion All the objectives of this study were accomplished. Both brand familiarity and brand trust were proven to serve as additional dimensions of consumer-based brand equity. Besides, most of the causal relationships were significantly identified. As a result, this study had successfully developed consumer-based brand equity in the Malaysian context of fast food industry. Remarkably, this study was in line with the theory of cognitive-affectiveconative, which classified perceived quality, brand awareness, brand familiarity, and cognitive brand image as cognitive characters. On the other hand, affective brand image and brand trust were categorized as affective characters, while attitudinal brand loyalty and brand equity were grouped into conative characters. Attitudinal brand loyalty played as a key variable for explicating the relationships between other dimensions and brand equity. In other words, brand equity had not existed when there was no attitudinal brand loyalty. In term of managerial implication, the finding of proposed model was simplified into four steps, each steps was contingent upon the successful completion of previous step, in line with “branding ladder” as introduced by Keller (2001). Lastly, it provided a vital input for government assistance programmes in developing the fundamental knowledge of branding strategy among local entrepreneurs. 203 APPENDIX Appendix A: Identified Brand Image Items (Preliminary Study) Brand Image Instruments Number of Mentioned Delicious 33 Easy and fast 25 Good physical environment 17 Pleasure 14 Free WiFi 13 Good customer service 11 A place for gathering 10 Many types of choices 8 Free refill 7 Convenience 7 Widely distributed 4 Affordable price 1 Famous 1 Happy meal 1 Toys 1 Rubbish food 1 Oily 1 Burger 1 Fries 1 Crunchy 1 Ice-cream 1 Coke 1 Wings 1 Whipped potato 1 Soft drink 1 Spicy 1 Pizza 1 Nugget 1 204 Appendix A: Identified Brand Image Items (Preliminary Study) (Continued) Brand Image Instruments Number of Mentioned Bun 1 Float 1 Big Mac 1 Sundae 1 Chicken 1 Wedges 1 Chili source 1 McFlurry 1 Finger 1 Cheese wedges 1 Original chicken 1 Big chicken 1 Cheese 1 Pineapple pie 1 Potato 1 Vegetable 1 Pineapple 1 Chicken frigs 1 205 Appendix B: Schedule of Data Collection Monday Tuesday Wednesday Thursday Friday Saturday Sunday 1-Apr 2-Apr 3-Apr Location: Suria KLCC 4-Apr 5-Apr 6-Apr 7-Apr Ph 8 1901 25 Ph 8 1901 25 Ph 9 1901 25 8-Apr 9-Apr 10-Apr Location: Mid Valley Megamall Ph 4 1901 15 Ph 4 1901 15 Ph 4 1901 15 Ph 4 1901 15 Ph 3 1901 5 Ph 3 1901 5 Ph 3 1901 5 11-Apr 12-Apr 13-Apr 14-Apr 15-Apr 16-Apr 17-Apr Location: Berjaya Times Square Shopping Mall McD 4 Mb 15 McD 4 Mb 15 McD 4 Mb 15 McD 4 Mb 15 McD 3 Mb 5 McD 3 Mb 5 McD 3 Mb 5 18-Apr 19-Apr 20-Apr 21-Apr 22-Apr 23-Apr 24-Apr Location: Jusco Metro Prima Shopping Centre KFC 8 Mb 15 KFC 8 Mb 15 KFC 9 Mb 15 Mb 15 Mb 5 Mb 5 Mb 5 25-Apr 26-Apr 27-Apr 28-Apr 29-Apr 30-Apr 1-May Location: Sungei Wang Plaza KFC 5 McD 20 KFC 5 McD 20 KFC 5 McD 15 KFC 10 McD 20 Location: Pavilion KL KFC 17 Pizza 17 KFC 17 Pizza 16 KFC 16 Pizza 17 Note: 1.Number (e.g. 12, 11, 25…) = Total numbers of respondents 2.McD=McDonald’s, KFC = Kentucky Fried Chicken, Ph=Pizza Hut, Mb=Marrybrown, 1901=1901 Hot Dogs 206 REFERENCES [1] Aaker, D.
