The cycle of trauma; relationship aggression in male Vietnam veterans with symptoms of posttraumatic stress disorder.

This study examined the association between symptoms of Posttraumatic Stress Disorder (PTSD) in male Vietnam veterans and their use of aggressive behavior in relationships with intimate female partners. Fifty couples participated in the study. Veterans reported on their PTSD symptoms, and veterans and partners completed measures assessing the veterans' use of physical, verbal, and psychological aggression during the preceding year as well as measures of their own perceptions of problems in the relationship. Results indicated that PTSD symptomatology places veterans at increased risk for perpetrating relationship aggression against their partners. The association between veterans' PTSD symptoms and their use of aggression in relationships was mediated by relationship problems. Clinical implications of these findings and suggestions for future research are discussed.
