Structure of Personality Disorders from the Perspective of the Revised Neo Personality Inventory Domain Scales and the Psychopathology-5 Scales

Abstract

This study tested the generality and comprehensiveness of the five-factor model of personality as applied to the Personality Adjective Checklist's (Strack, 1987) personality disorder scales. A sample of 258 undergraduates (113 men and 145 women) completed the Personality Adjective Checklist, the Revised NEO Personality Inventory, and the Psychopathology-5 Scales for partial course credit. A combined principal axis analysis with varimax rotation was performed for nonoverlapping scales of the Personality Adjective Checklist, the Revised NEO Personality Inventory domain scales and the Psychopathology-5 scales. The results indicated four factors which were identified as Neuroticism, Extraversion, Disagreeableness, and Conscientiousness. Openness did not emerge as a separate factor. These results supported the comprehensiveness but not the generality of the five-factor model as applied to personality disorders.
