Using structural equation modeling, we examined the impact of early-life stressors, war-zone stressors, and PTSD symptom severity on partner's reports of recent male-perpetrated intimate partner violence (IPV) among 376 Vietnam veteran couples. Results indicated that several variables demonstrated direct relationships with IPV, including relationship quality with mother, war-zone stressor variables, and PTSD symptom severity. Importantly, retrospective reports of a stressful early family life, childhood antisocial behavior, and war-zone stressors were indirectly associated with IPV via PTSD. One of our 2 war-zone stressor variables, perceived threat, had both direct and indirect (through PTSD) relationships with IPV. Experiencing PTSD symptoms as a result of previous trauma appears to increase an individual's risk for perpetrating IPV. Implications for research and treatment are discussed.
