Warzone deployment increases risk for posttraumatic stress disorder symptoms (PTSS), including among service members who have children. Parental PTSS are associated with child depression, anxiety, hyperactivity, and conduct problems, yet few studies of child behavioral health outcomes in military populations have accounted for PTSS in both warzone veterans and their partners. Fewer still incorporate non-clinically-recruited samples of nationally dispersed warzone veterans and their families. The current research examines whether children whose parent(s) have higher levels of PTSS exhibit more behavioral health symptoms. One hundred and thirty-three Iraq and Afghanistan War veterans and their cohabitating partners completed clinical interviews and self-report questionnaires. Higher intimate partner PTSS, more extensive child exposure to stressful life events, and being an adolescent were significantly associated with child depression after adjusting for warzone veteran PTSS, demographics, and recent warzone veteran absence from the household. Greater child exposure to stressful life events was also associated with child conduct problems. Treatment of PTSD symptoms experienced by warzone veterans' intimate partners, and preventative interventions aimed at helping the children of warzone veterans cope with stress, may ultimately yield positive benefits for the behavioral health of children in military families.
