The relative effects of intimate partner physical and sexual violence on post-traumatic stress disorder symptomatology.

This study examined the relative effects of intimate partner physical and sexual violence on Post-Traumatic Stress Disorder (PTSD) symptomatology. Severity of physical and sexual violence as well as PTSD severity were assessed in a sample of 62 help-seeking battered women. The results of this study were consistent with prior research, finding significant and positive relationships between physical and sexual violence as well as sexual violence and PTSD symptoms. In order to further clarify these relationships, the unique effects of sexual violence on PTSD were examined after controlling for physical violence severity. Results indicated that sexual violence severity explained a significant proportion of the variance in PTSD severity beyond that which was already accounted for by physical violence severity. These findings have important implications for mental health and social service professionals who work with battered women.
