Extensive work has documented an association between sustaining intimate partner violence (IPV) and posttraumatic stress disorder (PTSD) among women, yet little research has documented the same association in men, even though men comprise 25-50% of all IPV victims in a given year. Previous studies also show that women who sustain intimate terrorism (IT), a form of IPV that is characterized by much violence and controlling behavior, are at even greater risk for PTSD than women who sustain common couple violence (CCV), a lower level of more minor, reciprocal IPV. However, no research has documented this trend in men who sustain IT versus CCV. The present study investigates the associations among sustaining IPV and PTSD among both a clinical and community sample of men. The clinical sample is comprised of 302 men who sustained IT from their female partners and sought help. The community sample is comprised of 520 men, 16% of whom sustained CCV. Analyses showed that in both samples, the associations between sustaining several types of IPV and PTSD were significant, and that men who sustained IT were at exponentially increased risk of exceeding the clinical cut-off on the PTSD measure than men who sustained CCV or no violence. The path models predicting PTSD symptoms differed for both samples, indicating that perhaps treatment implications differ by group as well.
