The utility of the PAI and the MMPI-2 for discriminating PTSD, depression, and social phobia in trauma-exposed college students

Abstract

This study investigated the Minnesota Multiphasic Personality InventoryRevised (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, Kaemmer, 1989) and the Personality Assessment Inventory (PAI; Morey, 1991) with regard to each instrument's utility for discriminating post-traumatic stress disorder (PTSD) from depression and social phobia in a sample of college students with mixed civilian trauma exposure. Participants were 90 trauma-exposed undergraduates (16 male, 74 female) classified into one of four groups: PTSD, depressive disorders, social phobia, and well-adjusted. For both the PAI and the MMPI-2, profile analysis revealed that the groups differed in the elevation and shape of their profiles. The PAI Traumatic Stress subscale demonstrated good discriminant validity. © 2007 Sage Publications.
