Examining MMPI-2 F-family scales in PTSD-diagnosed veterans of Operation Enduring Freedom and Operation Iraqi Freedom.

Our study examined Minnesota Multiphasic Personality Inventory-2 (MMPI-2) F-family validity scales (F, Fb, F-K, Fp) in treatment-seeking veterans diagnosed with posttraumatic stress disorder (PTSD) related to Operation Enduring or Iraqi Freedom (OEF/OIF). Seventy-nine percent of veterans had F T scores over 65, 54% elevated F over 80 T; and 71% elevated Fb above 65 or 80. Fewer veterans elevated F-K ( 13; 22%) and Fp ( 100 T; 5%). Differences emerged between veterans with and without elevated ( 65 T) F scores on F-family validity scales, clinical scales, and self-report measures of psychopathology. Elevations for F-family validity scales at various cut points are reported.
