McDevitt-Murphy, M. E., Weathers, F. W., Flood, A. M., Eakin, D. E., & Benson, T. A. (2007). The utility of the PAI and the MMPI-2 for discriminating PTSD, depression, and social phobia in trauma-exposed college students. Assessment, 14(2), 181-195.

This study investigated the Minnesota Multiphasic Personality Inventory-Revised (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 posttraumatic 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. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
