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
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
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
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
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
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
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
Dimensional Model Disadvantages Less familiar Lacks clinical application May be too complex Disagreement exists about preference of which dimensional model to use
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
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
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
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
Paranoid Personality Disorder • A pervasive distrust and suspiciousness of others such that their motives are interpreted as malevolent. • Reluctant to confide in others • Hold grudges • Finds threatening hidden meaning in benign comments • Doubt the loyalty and trustworthiness of others • Requires 4 of the 7 possible criteria.
Paranoid Personality Disorder • Prevalence rates: 0.5 to 2.5 % • More common in men • Unlikely to seek treatment • Treatment – • Trusting atmosphere • Cognitive therapy to correct cognitive errors • Most therapists pessimistic
Schizoid Personality Disorder • A pervasive pattern of detachment from social relationships and a restricted range of expression of emotions in interpersonal settings - Doesn’t desire or enjoy close relationships - Prefers solitary activities and takes pleasure in few things - Is indifferent to praise and criticism • Requires 4 of the 7 possible criteria
Schizoid Personality Disorder • Prevalence: < 1% • More common in males • Unlikely to seek treatment • Many therapists think schizoid untreatable
Schizotypal Personality Disorder • A pervasive pattern of interpersonal and social deficits marked by acute discomfort with, and reduced capacity for, close relationships as well as by cognitive or perceptual distortions and eccentricities of behavior • Ideas of reference, magical thinking, and bodily illusions • Suspiciousness/paranoid thinking • Inappropriate affect • Lack of close friends/confidants • Social anxiety • Requires 5 of the 9 possible criteria
Schizotypal PD and Schizophrenia • Individuals with schizotypal PD: • Sometimes have a history of psychological trauma, especially childhood maltreatment • Are at an increased risk of developing schizophrenia • Are commonly relatives of individuals with schizophrenia • BUT…the vast majority of individuals with Schizotypal PD still do NOT have relatives with schizophrenia Individuals with Schizotypal PD People with Schizophrenia
Narcissistic Personality Disorder • A pervasive pattern of grandiosity, need for admiration, and lack of empathy • Preoccupied with fantasies • Associates only with high-status others • Has a strong sense of entitlement • Is interpersonally exploitative • Is envious and thinks others are envious of him/her • Requires 5 of the 9 possible criteria

Psychopathy • Deceptiveness or duplicity • Absence of empathy, compassion or remorse toward the victims of the psychopath's exploitative self-interest. • Can often be charming and appear socially well-adjusted. • May or may not engage in criminal behavior.
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
Social Factors & the Etiology of ASPD • Inconsistent discipline (or complete lack of discipline) often seen in the prior family history of ASPD men • Kids with a “difficult temperament” are especially irritating to parents • Parents respond inappropriately by giving up or becoming severe in punishment • Person selects friends who share antisocial interests and problems (‘skinheads’, gangs)

Psychological Factors: the Etiology of ASPD • Avoidance learning in the lab • Psychopaths unaffected by anticipation of punishment • Hypothesis 1: they can ignore the effects of punishment (emotional poverty) • Hypothesis 2: they have trouble shifting their attention (impulsivity)

Prevalence & Course: PD Summary • PDs often originate in childhood & become ingrained by adulthood • Overall prevalence rate of 10-14% • Course & prognosis depend on disorder, but prognosis is generally poor
