Group interpersonal psychotherapy for low-income women with posttraumatic stress disorder

The aim of this study was to assess the efficacy of group interpersonal psychotherapy (IPT) for low-income women with chronic posttraumatic stress disorder (PTSD) subsequent to interpersonal trauma. Non-treatment-seeking predominantly minority women were recruited in family planning and gynecology clinics. Individuals with interpersonal trauma histories (e.g., assault, abuse, and molestation) who met criteria for current PTSD (N=48) were randomly assigned to treatment or a wait list. Assessments were conducted at baseline, treatment termination, and 4-month follow-up; data analysis used a mixed-effects regression approach with an intent-to-treat sample. The results showed that IPT was significantly more effective than the wait list in reducing PTSD and depression symptom severity. IPT participants also had significantly lower scores than waitlist individuals on four interpersonal functioning subscales: Interpersonal Sensitivity, Need for Social Approval, Lack of Sociability, and Interpersonal Ambivalence.
