This study examined response styles of veterans seeking compensation for PTSD (N = 204). Veterans were classified as having a valid or overreporting response style based on their scores on three MMPI-2 validity scales that measure overreporting F, F(p), F-K. Sixteen percent of veterans had valid scores on all three scales. The number of veterans classified as having an overreporting response style differed depending on which scale was used. This finding highlights the importance of using multiple validity scales to measure response style. Veterans who were and were not classified as overreporters were compared on measures of combat exposure, PTSD, and depression.
