Modeling Risk For Intimate Partner Violence Among Recent-era Veteran-partner Dyads

Using an actor-partner interdependence model, we examined whether veterans’ post traumatic stress symptoms (PTSS)contributed to partners’ drug abuse symptoms,whether partners’ drug abuse symptoms contributed to intimate partner violence (IPV) perpetration, and whether drug abuse symptoms mediated PTSS-IPV perpetration associations. Participants were recent-era veterans who participated in the Mid-Atlantic Mental Illness Research, Education and Clinical Center Post-Deployment Mental Health study. Veterans who took part at one site and their partners (N = 49 couples) completed a follow-up study in which drug abuse symptoms and IPV perpetration were assessed. Veterans’ PTSS contributed to veterans’ drug abuse symptoms. Veterans’ drug abuse symptoms were associated with their IPV perpetration (i.e., an actor effect) and their partners’ IPV perpetration (i.e., a crossover effect). Drug abuse symptoms mediated the association between veterans’ PTSS and partners’ reports of IPV perpetration.Findings suggest complex relationships between PTSS,drug abuse problems and IPV perpetration among these dyads.
