Book excerpt: Perinatal depression (PND), depression that occurs during pregnancy or in the first year following delivery, is a common and debilitating mental health condition. In New York City, it is estimated that at least one in ten women suffer from PND. The clinicians who serve these women require training in acceptable, feasible, and effective treatments. Interpersonal psychotherapy (IPT) is a time-limited, evidence-based psychotherapy that has been found to be effective in the treatment of PND in community and primary care settings. The present study investigates the nuances of an IPT training program for licensed mental health providers who treat perinatal depression within integrated care settings in NYC. Using a qualitative-focused mixed-methods design, this study aims to systematically and comprehensively evaluate the acceptability, feasibility, sustainability, and preliminary effectiveness of the training program, and of the providers' perceptions of IPT as a treatment for the patients they serve.
