Personality Disorder Not Otherwise Specified Connecting Order with Disorder - A Quantitative, Continuum Model The Personality Style-Personality Disorder Continuum DSM-IV Definition of Personality Disorder A. An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual’s culture. This pattern is manifested in two (or more) of the following areas: 1. Cognition (i.e., ways of perceiving and interpreting self, other people, and events) 2. Affectivity (i.e., the range, intensity, ability, appropriateness of emotional response) 3. Interpersonal functioning 4. Impulse control DSM-IV Definition of Personality Disorder B. The enduring pattern is inflexible and pervasive across a broad range of personal and social situations. DSM-IV Definition of Personality Disorder C. The enduring pattern leads to clinically significant distress or impairment in social, occupational, or other important areas of functioning. DSM-IV Definition of Personality Disorder D. The pattern is stable and of long duration and its onset can be traced back at least to adolescence or early adulthood. DSM-IV Definition of Personality Disorder E. The enduring pattern is not better accounted for as a manifestation or consequence of another mental disorder. DSM-IV Definition of Personality Disorder F. The enduring pattern is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition (e.g., head trauma).

(There may be some psychopathic traits, but insufficient to meet Hare’s PCL-R criteria: score >29) Psychopathy without violence (viz., con-artists, financial scams) Psychopathy with violent crimes Psychopathy with sadistic control (viz., unlawful imprisonment of a kidnap victim while awaiting ransom) Psychopathy with violent sadism and murder, but no prolonged torture Psychopathy with prolonged torture followed by murder Stone, 2000 Treatability Presence of – Adequate motivation – Ability to take seriously the nature of one’s antisocial attitudes and behaviors Absence of – Pathological lying/deceitfulness – Conning/manipulativeness – Lack of remorse or guilt – Callousness/lack of compassion Stone, 2002 Psychopathy Kraeplin (1915) – Psychopathic personalities Cleckley (1940) – Psychopath Hare PCL-R PCL-R Factor-I Items Glibness, superficial charm Grandiose sense of self worth Pathological lying Conning/manipulative Lack of remorse or guilt Shallow affect Callous/lack of empathy Failure to accept responsibility for one’s actions Black, 1999 Example of Offender Recidivism 3 Year Reconviction PCL-R PCL-R PCL-R > 30 20-29 0-19 75% 50% 25% Hemphill et al., 1998 Predictors of ASPD Preschool child’s inability to inhibit socially inappropriate behavior predicts later asocial behavior, and undercontrolled behavior in school-age children is the best predictor of adult antisocial behavior. This association may be the most reliable relation between characteristics in young children and later psychopathology. From Kagan J, Zentner M, Early childhood predictors of adult psychopathology. Harvard Review of Psychiatry, 1996. Is ASPD Genetic? Genetic factors do play a significant role in antisocial behavior Twin studies show genetic factors to be particularly important in AS behavior with early-onset hyperactivity Genetic factors least influential in adolescent onset delinquency JIMMY, SIXTH-GENERATION PAIN IN THE ASS BORDERLINE Borderline Personality Disorder (DSM-IV) A pervasive pattern of instability of interpersonal relationships, selfimage, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts as indicated by five (or more) of the following: 1. Frantic efforts to avoid real or imagined abandonment. Note: do not include suicidal or self-mutilating behavior covered in Criterion 5. 2. A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation. 3. Identity disturbance: markedly and persistently unstable self-image or sense of self. 4. Impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating). Note: do not include suicidal or self-mutilating behavior covered in Criterion 5. Borderline Personality Disorder (DSM-IV) A pervasive pattern of instability of interpersonal relationships, selfimage, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts as indicated by five (or more) of the following: 5. Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior. 6. Affective instability due to a marked reactivity of mood (e.g., intense episodic dysphoria, irritability, or anxiety usually lasting a few hours and only rarely more than a few days). 7. Chronic feelings of emptiness. 8. Inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights). 9. Transient, stress-related paranoid ideation or severe dissociative symptoms. Heterogeneity of BPD DSM-IV - defined BPD is an extremely heterogeneous construct (Est. 256 varieties) Mix of unstable, stress-induced symptoms and stable personality characteristics (i.e., dimensional traits) BPD as a Personality Disorder Emerging From the Interaction of Underlying Genetically-Based Traits Impulsive aggression and affective instability = heritable endophenotypes that would contribute significantly to development of BPD Siever et al., 2002 Heritability of BPD Twin study (Torgersen et al. 2000) Novelty seeking (Cloninger, 2005) Impulsivity (New and Siever, 2002) Childhood Abuse and BPD Severe childhood trauma persistent serotonergic disturbance Dose/response correlation (age of onset, frequency, seriousness) Only males show serotonin and aggression or impulsivity Sustained childhood abuse – Hyporesponsiveness of 5-HT system – Hyper-responsiveness of HPA system (correlated with sustained abuse, not BPD pathology) To know what characterizes BPD, must correct for chronic childhood trauma Possibly faulty attachment in genetically vulnerable children selected by abusers sustained abuse HPA disturbances susceptibility to stress and stress-related disorders (e.g. BPD, MDD) Rinne, T, ISSPD, Florence, 2003 MRI in Patients with BPD 16% reduction in volume of hippocampus 8% reduction in volume of amygdala in BPD patients vs. healthy controls Not clearly related to trauma (results only significant for total BPD group [with and without hx of trauma]) Driessen et al., 2000 MRI in Patients with BPD ↓ Volume hippocampus and amygdala (Schmahl et al, 2003; Rusch et al., 2003) PET and BPD BPD patients vs Controls • frontal and prefrontal hypermetabolism • hippocampus and cuneus hypometabolism = limbic and prefrontal dysfunction, implicated in regulation of emotion Juengling et al., 2003 Implications of Imaging Studies in BPD Abnormalities in prefrontal, corticostriatal, and limbic networks Perhaps related to lowered serotonin neurotransmission and behavioral disinhibition.

Etkin et al., 2005 Biology in the Service of Psychotherapy Areas decreased after vs. before treatment amygdala cognitive-behavioral therapy citalopram From Furmark et al., 2002. Biology in the Service of Psychotherapy Identification of brain regions associated with deficits of impulse control in patients with BPD may be useful to predict a patient’s ability to respond to psychotherapy and recover. Etkin et al., 2005 Toward a New Model of PDs for DSM-V Categorical vs. Dimensional Models: Advantages and Disadvantages Limitations of categorical model • Excessive diagnostic co-occurrence, i.e., most patients meet criteria for more than one PD. • Heterogeneity among persons with the same diagnosis, e.g., there are 256 ways to meet criteria for BPD. • Arbitrary diagnostic thresholds, i.e., no empirical rationale for boundary with “normal” personality functioning. • Inadequate coverage, e.g., PDNOS is the most frequently used diagnosis. Limitations of dimensional models • Unfamiliar to those trained in medical model, i.e., communication of much information via single diagnostic concept. • More complex and difficult to use, e.g., up to 30 dimensions to describe personality. • Little empirical information on treatment or other clinical implications of scale elevations or on cut-points for clinical decision-making. Personality Disorders and the Research Agenda for DSM-V • “There is a clear need for dimensional models to be developed and their utility compared with that of existing typologies in one or more limited fields, such as personality. If a dimensional system performs well and is acceptable to clinicians, it might be appropriate to explore dimensional approaches in other domains (e.g., psychotic or mood disorders)” (Rounsaville et al., 2002). • Thus, personality disorders are “test case” for return to a dimensional approach to the diagnosis of mental disorders in DSM-V. 18 Alternative Proposals for a Dimensional Model of Personality Disorders • Proposals to provide dimensional representation of existing constructs. • Proposals to provide dimensional reorganization of diagnostic criteria. • Proposals to integrate Axes II and I with respect to common spectra. • Proposals to integrate Axis II with dimensional models of general personality structure. 18 Alternative Proposals for a Dimensional Model of Personality Disorders • Proposals to provide dimensional representation of existing constructs: Oldham & Skodol (2000) Any instrument Tyrer & Johnson (1996) Personality Assessment Schedule (PAS) S&W Assessment Procedure (SWAP-200) Westen & Schedler (2000) (Widiger & Simonsen: JPD, 2005) Dimensional Representation of DSM-IV PD Categories Summary Term • Absent (1) • Traits (2) • Subthreshold (3) • Threshold (4) • Pervasive (5) • Prototypic (6) Number of Criteria Met 0 1, 2, or 3 3 or 4 4 or 5 5, 6, 7, or 8 7, 8, or 9 Oldham & Skodol: JPD, 2000 PROPOSAL Axis II: Personality Disorder Traits and Personality Disorders Instructions: Personality disorder traits or personality disorders are identified according to the number of criteria met, as specified in each personality diagnosis, utilizing the following categories: - Absent - Traits - Subthreshold features - Threshold - Moderate - Prototype PROPOSAL (continued) Instructions (continued): If a patient is at or above threshold for up to two PDs, the diagnosis or diagnoses should be made.
