Abstract Created by REACH:
Military sexual trauma includes experiences of sexual harassment (e.g., unwanted threatening or repeated sexual attention) and sexual assault (e.g., sexual contact against one’s will) during one’s time in the military. Experiencing military sexual trauma may predict adverse outcomes, including posttraumatic stress disorder (PTSD) symptoms and intimate partner violence (IPV) victimization and perpetration. More specifically, those who experience sexual trauma and PTSD may be at increased risk of IPV victimization or perpetration in other relationships due to a decreased ability to manage risk and regulate emotions, which is particularly true for women because they are more likely to experience military sexual trauma than men. This longitudinal study of 187 women Veterans examined whether a history of military sexual trauma, measured at baseline (Time 1), was associated with being a victim of physical, sexual, and psychological IPV 18 months later (Time 2) and both IPV victimization and perpetration six months after that (Time 3). Additionally, PTSD measured at Time 2 was examined as a link between experiences of military sexual trauma and IPV. In this sample, military sexual assault predicted greater PTSD symptoms and, in turn, IPV victimization and perpetration, indicating that PTSD symptoms may partially explain the association between military sexual assault and IPV victimization and perpetration.

Significant research has focused on intimate partner violence (IPV) victimization among women Veterans, yet much less is known about women Veterans’ IPV perpetration. Although military sexual trauma (MST) is a predictor of IPV victimization, military sexual assault (MSA), a component of MST, may predict especially adverse consequences for women Veterans. This study examined the unique effects of MSA on IPV victimization of, and perpetration by, women Veterans, and investigated posttraumatic stress disorder (PTSD) symptoms and prior IPV victimization as potential mediators of IPV perpetration. Participants included 187 women Veterans drawn from a larger web-based survey. We assessed the two components of MST (MSA and harassment) at Time 1 (T1), PTSD symptoms at Time 2 (T2), IPV victimization at T2 and Time 3 (T3), and IPV perpetration at T3. MSA predicted multiple subtypes of IPV victimization and perpetration, whereas harassment predicted neither. Those who reported MSA were more likely to experience T3 psychological and sexual IPV victimization, with PTSD symptoms significantly mediating this path. MSA was also directly related to T3 psychological IPV perpetration and indirectly related to physical and sexual IPV perpetration through PTSD symptoms. MSA was directly related to T2 PTSD symptoms while T2 IPV victimization was directly related to T3 IPV perpetration. These findings underscore that women Veterans’ IPV perpetration may be in response to their own IPV victimization through self-defense and/or due to their PTSD symptoms. Results support prevention, screening, and treatment for IPV victimization and PTSD symptoms to lower risk of future IPV revictimization and perpetration.
