Intimate Partner Violence in Adolescence: Associations With Perpetration Trauma, Rumination, and Posttraumatic Stress

Engagement in intimate partner violence (IPV) is related to a host of negative outcomes for youth, including posttraumatic stress symptoms (PTSS). Moreover, research indicates that the perpetration of violence may constitute a traumatic experience, termed perpetration trauma (PT), which, in turn, is related to elevated levels of PTSS. Little research to date, however, has illuminated the underlying processes that may link IPV perpetration, PT, and PTSS. One potential contributor to this association is rumination on negative emotions. In particular, for youth who report PT and rumination, engaging in IPV may be associated with elevations in PTSS. To investigate this hypothesis, data were gathered from a sample of 235 justice-involved youth (184 boys, 51 girls) who completed self-report measures of IPV perpetration and victimization, PT, sadness and anger rumination, and PTSS. Results of moderated mediational analyses indicated that IPV perpetration was related to PTSS through sadness rumination, and that these effects were stronger when youth endorsed PT. In turn, IPV perpetration was related to PTSS through anger rumination only when youth did not endorse PT. In addition, tests of alternative models indicated that these results were specific to IPV perpetration, given that IPV victimization was not related to PTSS through anger or sadness rumination when youth endorsed PT. These results suggest that the combination of rumination on sadness and endorsement of PT may put youth who perpetrate IPV at the greatest risk of PTSS. Therefore, interventions seeking to interrupt the cycle of IPV perpetration may benefit from targeting perpetrators' sadness rumination, PT, and PTSS.
