Part 2: Conceptualisations of Youth Psychopathy (PCL:YV and ASPD) Part 3: Developmental Issues Part 4: Discussion What is Psychopathy A personality disorder... “…an enduring pattern of inner experience and behaviour that deviates markedly from the expectations of the individuals culture, is pervasive and inflexible, has an onset in adolescence or early adulthood, is stable over time, and leads to distress or impairment” (DSM-IV, APA, 1994, p. 629) Manie sans delire (Pinel, 1800s) …individuals engaging in deviant behavior but exhibiting no signs of a mental illness or disorder… The Mask of Sanity (Clecley 1971) • 16 behavioral characteristics of a psychopath: – – – – – – – – – – – – – – – – Superficial charm and good intelligence Absence of delusions and other signs of irrational thinking Absence of nervousness or psychoneurotic manifestations Unreliability Untruthfulness and insincerity Lack of remorse or shame Inadequately motivated antisocial behaviour Poor judgment and failure to learn by experience Pathologic egocentricity and incapacity for love General poverty in major affective reactions Specific loss of insight Unresponsiveness in general interpersonal relations Fantastic and uninviting behavior with drink and sometimes without Suicide threats rarely carried out Sex life impersonal, trivial, and poorly integrated Failure to follow any life plan.

The precursors…first reveal themselves early in life” Hare (1994) Difficult temperament ADHD ODD CD Substance Use Serious Crimes Test key hypothesis about development III. ETIOLOGICAL MECHANISMS 11.

But if he emerged into adulthood as a man who is irritable and moody, we may grant that the surface behaviour has changed but claim that the underlying personality type has not. Although the form of behaviour changes over time, the course of personality is said to evidence coherence if the qualities of behaviour are preserved over time (p. 168) Transient Developmental Phenomena (Seagrave and Grisso, 2002) Arrogant and Deceitful.......or..... Immature theory of mind, egocentricism common to youth (Piaget, 1972, 1973) Irresponsible/Impulsive......or.......”normal “ sensation seeking and lack of consequential thinking Deficient Affective Experience...or.....Egocentricism Aetiology • Assumed biological primacy • What about Inductive parenting?? • Direction of effects – Transactional – Interactional – Unidirectional – Bi-directional • Absence of empirical data providing conclusive evidence Equifinality and Multifinality Attachment Trauma Parenting Genetic Differential Diagnoses 1) ADHD + Attachment Disorder + Conduct Disorder 2) Prodromal phase of psychosis 3) Developmental disorders (Autism, Asperger) Potentially Useful Construct Key differences with the adult literature and developmental concerns Priority for Research Implications for the practitioner • How can the construct be meaningfully applied in forensic child and adolescent settings? Clinical use should be for speculation, not diagnosis or decision making
