Participants in this 16-week single-blind study will be randomly assigned to receive either IPT-AG or TAU in a school-based clinic. Participants assigned to receive IPT-AG will attend two to three, 40-minute individual pre-group sessions, followed by 12, 90-minute group therapy sessions and two additional individual sessions—one midway through the group sessions and another upon completion of group therapy. TAU will consist of counseling sessions as regularly conducted by the school clinic social worker and/or referral to another agency. Study visits will occur at baseline and Weeks 4, 8, 12, and 16, or upon early termination. At the end of 16 weeks, participants assigned to receive IPT-AG will continue in a maintenance program in which they will receive IPT-AG once a month for an additional 6 months. All participants will also be assessed 6 and 12 months post-treatment to measure depressive symptoms, global and social functioning, satisfaction with care, and utilization of other services.
