  1. CHAPTER NINE Personality Disorders

  2. Personality Disorders • What are Personality Disorders? • Classification of Personality Disorders Categorical vs. Dimensional models • Features of Axis II Implications for Assessment • Specific Disorders: Cluster A Cluster B Cluster C

  3. Personality • Most mental disorders are defined in terms of states: episodes of symptoms • Personality refers to enduring traits that are fairly stable over time or make a person who s/he is

  4. What are Personality Disorders? • Enduring patterns of perceiving,relating to & thinking about the environment and oneself • that are inflexible and pervasive • and cause either significantfunctional impairmentorsubjective distress

  5. Categorical Classification of PDs (DSM) • Advantages Familiar & convenient  Ease in communication  Consistent with clinical diagnoses

  6. Categorical Classification of PDs (DSM) • Disadvantages  low inter-rater reliability  very high comorbidity  high overlap among symptom criteria  not based on a theoretical model  ambiguity occurs regarding the presence vs. absence of a PD  most commonly diagnosed PD is PD-NOS

  7. Dimensional Model of Personality Personality Disorder • Looks at a continuum of normal to abnormal personality • all individuals have some degree of these traits, but those with PDs have maladaptive levels • Various dimensional models exist • Five Factor Dimensional Model trait Normal Traits

  8. Five-Factor Model • Neuroticism: expression of negative emotions • Extraversion: interest in interacting with other people; positive emotions • Openness: willingness to consider and explore unfamiliar ideas, feelings, and activities • Agreeableness: willingness to cooperate and empathize with others • Conscientiousness: persistence in pursuit of goals; organization; dependability

  9. Dimensional Model • Advantages  Theoretical basis  Retention of information • Leads to less stereotyping • Adaptive traits are also highlighted  Flexible  Resolution of a variety of classification dilemmas • Avoids arbitrary assignment decisions • Addresses problems with comorbidity in the Categorical Model • Higher inter-rater reliability

  10. Dimensional Model Disadvantages  Less familiar  Lacks clinical application  May be too complex  Disagreement exists about preference of which dimensional model to use

  11. Features of Axis II • Different etiology than Axis I • not always true • More stable than Axis I disorders or more resistant to treatment • however, some Axis I disorders are very stable • some PDs are treatable

  12. Features of Axis II • Other disorders: ego-dystonic • personal distress, discomfort with one’s symptoms • Personality disorders: ego-syntonic • ideas and impulses do not bother the person

  13. Assessment of PDs • The ego-syntonic nature of personality disorders can make them difficult to assess using traditional measures • Others who have regular contact with an individual might be better judges of how that person’s behavior affects those around him/her

  14. Culture and Personality • Culture plays a large role in determining what is appropriate or acceptable at a given time and place • Cultures may differ in:  Degree of emotional expression  Individualism vs. collectivism

  15. Clusters of Personality Disorders • Cluster A  Paranoid PD  Schizoid PD  Schizotypal PD • Cluster B  Narcissistic PD  Antisocial PD  Histrionic PD  Borderline PD • Cluster C  Avoidant PD  Dependent PD  Obsessive-Compulsive PD

  34. Antisocial PD and Psychopathy • Earlier conceptualizations of ASPD had a greater overlap with psychopathy • However, due to DSM-IV’s focus on observable behaviors, ASPD is a distinct concept from psychopathy (there is still some overlap) • Psychopathy is a better predictor of recidivism than ASPD

  35. Overlap between ASPD, Psychopathy, & Criminality 20% of people with ASPD are Psychopaths ASPD Psychopaths Criminals 75-85% of criminals have ASPD 15-25% of criminals are Psychopaths
