Objective This study employed latent class analysis to identify profiles of women experiencing intimate partner violence (IPV) based on the severity of posttraumatic stress disorder (PTSD) symptoms. Method Self‐report data from a sample of 369 women experiencing bidirectional IPV was used. Results A 3‐class solution comprising low, moderate, and high PTSD severity profiles best fit the data. Profiles were differentially related to whether IPV victimization was considered traumatic (PTSD criterion A); whether functioning was impaired as a result of PTSD symptoms (PTSD criterion F); whether the woman met full diagnostic criteria for PTSD; depression symptom severity; and severity of psychological, physical, and sexual IPV victimization and use of IPV. An extremely high percentage of women in the high (96%) and moderate (88%) severity classes experienced functional impairment, although many did not meet full diagnostic criteria for PTSD. Conclusions Findings support the need for interventions individually tailored to one's treatment needs based on the nature of one's traumatic stressor and the impact of PTSD on daily functioning.
