The Personality Assessment Inventory (PAI; Morey, 1991) is a 344-item self-report inventory that assesses various domains of personality and psychopathology among adults and was designed for use in professional and research settings. Items are answered on a 4-point Likert-type scale according to the extent to which they reflect true descriptions of client experiences. These items are then combined into 22 nonoverlapping full scales, including 4 validity scales, 11 clinical scales, 5 treatment consideration scales, and 2 interpersonal scales (see Table 1). As shown in Table 1, 10 of the full scales contain conceptually derived subscales that were designed to facilitate interpretation and coverage of the clinical constructs. Administration of the inventory takes approximately 50–60 minutes, and test takers should have a reading ability at the fourth-grade level.
