The present study examined psychological coping styles and mental health treatment histories in veterans with PTSD. This study also served as a replication and extension of an earlier investigation that assessed the prevalence of PTSD in World War II, Korea, and Vietnam combat veterans who were seeking medical treatment. Thirty-six combat veteran medical patients were compared to 38 war-era controls. Nearly a third of the combat veterans met psychometric criteria for PTSD; none of the controls met these criteria. Both PTSD-positive subjects and mental health treatment seekers showed a significantly greater use of emotion-focused coping. Results also showed that Vietnam combatants were more likely to have received individual mental health treatment. These findings and their treatment implications are discussed.
