Systematic research on effective treatment for survivors of childhood sexual abuse with posttraumatic stress disorder (PTSD) is virtually non-existent. The aim of the present study was to compare the effectiveness of an affect-management treatment (AM) group to a wait list control condition for female survivors of childhood sexual abuse with PTSD. Forty-eight female survivors of childhood sexual abuse with PTSD were randomly assigned to either a 15-week affect-management treatment group or to a wait list control condition. All subjects received individual psychotherapy and pharmacotherapy for the duration of the study, and for at least 1-month prior to the study. Controlling for pretreatment scores, subjects who completed the affect-management treatment group (n = 17) reported significantly fewer posttreatment symptoms of PTSD and dissociation than subjects in the wait list control condition (n = 16). Our findings suggest that an affect-management group treatment is beneficial as an adjunct to individual psychotherapy and pharmacotherapy for survivors of childhood sexual abuse with PTSD.
