A structured interview for the assessment of the Five-Factor Model of personality: Facet-level relations to the axis II personality disorders

The Structured Interview for the Five-Factor Model (SIFFM; Trull & Widiger, 1997) is an 120-item semistructured interview that assesses both adaptive and maladaptive features of the personality traits included in the five-fac tor model of personality, or "Big Five." In this article, we evaluate the a bility of SIFFM scores to predict personality disorder symptomatology in a sample of 232 adults (46 outpatients and 186 nonclinical college students). Personality disorder symptoms were assessed using the Personality Diagnost ic Questionnaire-Revised (PDQ-R; Hyler & Rider, 1987). Results indicated th at many of the predicted associations between lower-order personality trait s and personality disorders were supported. Further, many of these associat ions held even after controlling for comorbid personality disorder symptoms . These findings may help inform conceptualizations of the personality diso rders, as well as etiological theories and treatment.
