The intervention will be assessed through a practical randomized controlled trial in which we have recruited 168 pregnant women with major depression and/or dysthymia who were on Medicaid and/or received Maternal Support Services (MSS) in selected public health centers in Seattle - King County (PHSKC). Patients who were eligible and consented to study enrollment were randomly assigned to either usual care (UC) or MOMCare. Baseline and four follow-up assessments (3 - 18 months post-baseline) are scheduled for study participants in both groups. The MOMCare intervention includes a choice of brief interpersonal psychotherapy or collaborative management of antidepressant medication. Treatment response will be monitored, and the treatment will be adjusted as necessary (adding treatments, increasing dosages).
