Abstract summary 

The purpose of the present study was to test the efficacy of sertraline and Interpersonal Psychotherapy (IPT) relative to pill placebo in a two site randomized controlled trial over a period of 12 weeks. It was hypothesized that sertraline and IPT would be more efficacious than pill placebo with respect to depression and social adjustment.162 breastfeeding and non-breastfeeding women experiencing a major depressive episode in the first year postpartum from two sites in Iowa and Rhode Island were randomly assigned to IPT, sertraline-clinical management (CM), or pill placebo-CM. CM included infant-focused psychoeducation. Interview-based and self-report measures of depression and social adjustment were obtained at baseline, 4-weeks, 8-weeks, and 12-weeks of treatment. Linear mixed effects regression (LMER) was used for the longitudinal data analysis.There was no significant effect for treatment condition associated with the primary outcome measure, the HamD-17, but there was a significant effect for sertraline-CM relative to the IPT and placebo conditions over the duration of the trial based on the General Depression scale of the Inventory of Depression and Anxiety Symptoms. There was a main effect for time in that study subjects across all three conditions showed significant improvement for the duration of the trial.Limitations of the present study included significant non-engagement with assigned condition and differential effects of IPT across the two study sites.There was improvement for all postpartum women in all conditions. The results do suggest that active interventions with or without medication delivered over a period of twelve weeks can lead to significant improvement in depression and social adjustment among postpartum women.
