This study sought to determine the relative contribution of problems in emotion regulation and interpersonal functioning compared to PTSD symptoms in predicting functional impairment among women with childhood abuse histories. One hundred sixty-four treatment-seeking women completed measures of emotion regulation, interpersonal problems, PTSD symptoms, and social adjustment. Severity of PTSD symptoms was a significant predictor of functional impairment. In addition, after controlling for the effects of PTSD symptomatology, emotion regulation and interpersonal problems were both significant predictors and together made contributions to functional impairment equal to that of PTSD symptoms. These data indicate that emotion regulation and interpersonal problems play an important role in functional impairment among women with a history of childhood abuse. These factors should be taken into account in treatment planning to ensure successful rehabilitation from the long-term effects of chronic childhood trauma.
