 Participants found to be depressed on the first visit will then be assigned randomly to receive group IPT or TAU. Participants assigned to group IPT will attend 12 weekly psychiatrist-led sessions that will focus on overcoming relationship problems associated with depression. The first two and last sessions will be alone with the psychiatrist and the remaining sessions will be with a group of five to eight other pregnant women. Participants assigned to TAU will be referred to outpatient treatment, which may include cognitive behavioral psychotherapy, insight-oriented psychotherapy, andor antidepressant medication. TAU participants receiving psychotherapy will attend 12 weekly treatment sessions comparable to the IPT group sessions; treatment for TAU participants receiving antidepressant medication may last longer than 12 weeks. During the treatment period, all participants will fill out weekly forms about their moods and will have monthly interviews with a psychiatrist. Upon completion of treatment, participants will have a 30-minute final evaluation meeting.
