Personality Disorders (PD)


Longstanding, pervasive, inflexible patterns of behavior
and inner experience
Patterns present in at least 2 areas:
»
»
»
»


Cognition
Emotions
Relationships
Impulse control
Coded on Axis II
Often comorbid with Axis I disorders
» More severe symptoms and poorer outcome when comorbid
– 50+% of people diagnosed with a personality disorder meet
criteria for another personality disorder
– More than two-thirds meet lifetime criteria for an Axis I disorder
(Lenzenwenger et al., 2007)

Classifying Personality Disorders


DSM-IV-TR categorical approach
Classifies in 3 clusters:
» Cluster A Odd/Eccentric
» Cluster B Dramatic/Erratic
» Cluster C Anxious/Fearful

Diagnostic reliability
» Initially poor; improved since DSM-III

Test-retest reliability (diagnostic stability)
» ½ of those initially diagnosed with PD did not receive same
diagnosis 1 year later (Shea et al., 2002)

Gender bias
» Certain diagnoses applied more often to men, others to
women

disorders and major depressive disorder across
6-, 12-, and 24-month follow-up interviews
7
Dimensional Approach: Five-Factor
Model

Five-factor model (McCrae & Costa, 1990)
» Neuroticism, extraversion/introversion, openness
to experience, agreeableness/antagonism, and
conscientiousness
» Five factors are heritable

Personality traits form a continuum
» Individuals with PDs endorse the extremes

Dimensional approach involves rating each
individual on the five factors
» Avoids applying a categorical label which may not
completely fit
8
Dimensional Approach: Five-Factor
Model



Most personality disorders are
characterized by high neuroticism and
antagonism.
High extraversion tied to histrionic and
narcissistic disorders (involve dramatic
behavior)
Low extraversion linked to disorders that
involve social isolation, such as schizoid,
schizotypal, and avoidant personality
disorders

Personality Inventory assessing Five-Factor
Model

Odd/Eccentric Cluster: Paranoid
Personality Disorder

Suspicious

» Secretive; reluctant to
confide in others

Expects to be
mistreated/exploited
» Vigilant for hints of abuse


More common in men
than women
Cormorbidity high for
» Schizotypal
» Borderline
» Avoidant

things go wrong
Questions loyalty

blown delusions
11
Odd/Eccentric Cluster: Schizoid

Avoids close
interpersonal
relationships

» Schizotypal
» Avoidant
» Paranoid

13
Etiology of the PDS in Odd/Eccentric
Cluster


Highly heritable
Links to schizophrenia
» Relatives of individuals with schizophrenia at
greater risk for schizotypal
» Individuals with schizotypal PD show problems
similar to those found in schizophrenia
– Cognitive and neuropsychological deficits
– Enlarged ventricles
– Less temporal gray matter
14
Dramatic/Erratic Cluster: Borderline
Personality Disorder (BPD)









Impulsive, self-damaging behaviors
Unstable, stormy, intense relationships
Emotional reactivity
Frantic efforts to avoid abandonment
Unstable sense of self
Anger control problems
Chronic feelings of emptiness
Recurrent suicidal gestures
Transient psychotic or dissociative symptoms
15
Dramatic/Erratic Cluster: Borderline
Personality Disorder (BPD)


Onset during adolescence or early adulthood
Prognosis poor within 10 years of diagnosis
» Later in life, most no longer meet diagnostic criteria
(Paris, 2002)

Cormorbidity high with PTSD, MDD,
substance-related, and eating disorders
» Comorbidity predicts symptoms 6 years later

Suicide rates high
» Self-mutilation also a problem
16
Etiology of Borderline Personality Disorder
(BPD): Neurobiological factors

Genetic component
» Highly heritable
» May play a role in impulsivity and emotional
dysregulation
Decreased functioning of serotonin
system
 Frontal lobe dysfunction
 Increased activation of amygdala

17
(BPD): Social Environmental Factors



Parental separation
Verbal and emotional abuse during childhood
Object-Relations Theory (Kernberg, 1985)
» Introjection
» Object-representation
– BPD involves disturbed object representations, possibly due to
inconsistent parenting
» Conflict between introjected values and current needs
– Splitting
18
(BPD): Social Environmental Factors

Linehan’s Diathesis-Stress Theory
» Individuals with BPD have difficulty controlling
their emotions
– Possible biological diathesis
» Family invalidates or discounts emotional
experiences and expression
» Interaction between extreme emotional reactivity
and invalidating family → BPD
19
Figure 12.2 Linehan’s DiathesisStress Theory of BPD
20
Dramatic/Erratic Cluster: Histrionic




Emotionally shallow despite strong displays of
emotion

Overly concerned with physical attractiveness
May be sexually provocative and seductive
21
Etiology of Histrionic Personality
Disorder

Psychoanalytic theory
» Emotional displays and seductiveness
result from parental seductiveness
– Father’s sexual attention towards daughter
» Conflicting family attitudes towards
sexuality
– Negative attitudes towards sex while
simultaneously acknowledging titillation

Theory untested

23
Etiology of Narcissistic Personality
Disorder

Kohut’s Self-Psychology Model
» Characteristics mask low self-esteem
» In childhood, narcissist valued as a means to increase
parent’s own self-esteem
– Not valued for his or her own competency and self worth

» People with high levels of narcissism report cold
parents who overemphasized child’s achievement
Social cognitive model
» Narcissist has low self esteem
» Sense of self depends on “winning”
» Interpersonal relationships are a way to bolster sagging self
esteem rather than increase closeness to others
» Lab studies reveal cognitive biases that maintain narcissism
