Objective: To evaluate performance characteristics of DSM-IV Personality Disorders (PDs) criteria.

Method: Six hundred and sixty-eight adults recruited for the Collaborative Longitudinal Personality Disorders Study (CLPS) were assessed with diagnostic interviews.

Results: Within-category inter-relatedness was evaluated by Cronbach’s alpha and median intercriterion correlations (MIC). Cronbach’s alpha ranged from 0.47 to 0.87 (median=0.71); seven of the 10 PDs had alphas greater than 0.70. Between-category criterion overlap was evaluated by ‘inter-category’ intercriterion correlations between all PD pairs (ICMIC). ICMIC values (median=0.08) were lower than MIC values (median=0.23). Diagnostic efficiency statistics (sensitivity, specificity, positive predictive power and negative predictive power were calculated for …

Objective: Utilization of mental health treatment was compared in patients with personality disorders and patients with major depressive disorder without personality disorder.

Method: Semistructured interviews were used to assess diagnosis and treatment history of 664 patients in four representative personality disorder groups—schizotypal, borderline, avoidant, and obsessive-compulsive—and in a comparison group of patients with major depressive disorder.

Results: Patients with personality disorders had more extensive histories of psychiatric outpatient, inpatient, and psychopharmacologic treatment than patients with major depressive disorder. Compared to the depression group, patients with borderline personality disorder were significantly more likely to have received every type of psychosocial treatment …

Schizotypal Personality Questionnaire-Brief: Factor Structure And Convergent Validity In Inpatient Adolescents, Seth R. Axelrod, Carlos M. Grilo, Charles A. Sanislow, Thomas H. Mcglashan

We examined the internal consistency, factor structure, and validity of the Schizotypal Personality Questionnaire-Brief (SPQ-B). Two hundred thirty-seven psychiatrically hospitalized adolescents were administered the SPQ-B and a battery of well-established self-report instruments. The SPQ-B demonstrated adequate internal consistency. Exploratory factor analysis provided mixed support for the SPQ-B 3-factor structure of interpersonal deficits, cognitive-perceptual deficits, and disorganization. The Interpersonal and Cognitive-Perceptual subscales demonstrated convergent and discriminant relationships with other measures of interpersonal impairment and cognitive abnormalities. We concluded that the SPQ-B is a promising measure for evaluating schizotypal personality disorder features, specifically interpersonal and cognitiveperceptual deficits, with adolescent psychiatric inpatients.
