Sexual assault characteristics and posttraumatic stress symptoms among collegiate women: The role of posttraumatic cognitions

Abstract

Although it is well‐established that sexual assault is a risk factor for posttraumatic stress symptoms (PTSS) and other negative mental health outcomes, research is needed to help identify which individuals are most likely to experience ongoing distress following sexual assault. Negative cognitions following trauma may be influenced by sexual assault characteristics and have been shown to be associated with PTSS. The present study examined whether sexual assault characteristics were associated with PTSS by way of posttraumatic cognitions in a sample of 475 female college students who had experienced a sexual assault since the age of 14 years. Participants completed an online survey that included questions about sexual assault characteristics (i.e., whether the perpetrator used force, whether they experienced a freeze response), posttraumatic cognitions, and PTSS. Path analysis revealed that survivors who indicated they froze during the assault reported higher levels of PTSS, total effect = .28, p < .001, direct effect = .19, p < .001; posttraumatic cognitions regarding others, indirect effect = .02, p = .047, and other‐safety, indirect effect = .05, p = .003, partially accounted for this association. Only the direct effect of perpetrator use of force on PTSS was statistically significant, total effect = .23, p = .090, direct effect = .16, p = .009; none of the indirect effects were statistically significant, ps = .063–.669. The results support that assault characteristics are associated with postassault outcomes and are consistent with the cognitive model of posttraumatic stress disorder.
