Forty-five female outpatients sexually abused in childhood were offered a 2-year phase-divided group therapy. Before and after treatment and at 12 months follow-up, they answered questionnaires designed to elicit responses concerning psychological symptoms (Symptom Checklist; SCL-90) and sense of coherence (SOC). Symptoms for posttraumatic stress disorder (PTSD) were assessed before and after treatment. Inpatient days and sick listing days were assessed during 2 years before and 2 years after treatment. The psychological and PTSD symptoms were significantly reduced after treatment, and the SOC was increased as well. Inpatient days were decreased, and sick listing days increased but not significantly. Compared to a similar short-term focused therapy group and a waiting-list group there were no significant differences between the groups. Trauma-focused group therapy for women who were sexually abused in childhood seems to have promising effects on mental health, both concerning long-term and short-term approaches.
