The process of developing and implementing a telephone-based peer support program for postpartum depression: evidence from two randomized controlled trials

Background: A randomized controlled trial evaluated the effect of telephone-based peer support on preventing postpartum depression (PPD) among high-risk mothers. The results indicated that support provided by peer volunteers may be an effective preventative strategy. The purpose of this paper is to outline the process of developing, implementing, maintaining, and evaluating the peer support program that we used in this PPD prevention trial. Methods: The peer support program had been used successfully in a pilot trial and a previous breastfeeding peer support trial. Based on our experience and lessons learned, we developed a 4-phase, 12-step approach so that the peer support model could be copied and used by different health providers in various settings. We will use the PPD prevention trial to demonstrate the suggested steps. Results: The trial aim to prevent the onset of PPD was established. Peer volunteers who previously experienced and recovered from self-reported PPD were recruited and attended a four-hour training session. Volunteers were screened and those identified as appropriate to provide support to postpartum mothers were selected. Women who scored more than 9 on the Edinburgh Postnatal Depression Scale within the first two weeks after childbirth were recruited to participate in the trial and proactive, individualized, telephone-based peer support (mother-to-mother) was provided to those randomized to the intervention group. Peer volunteers maintained the intervention, supported other volunteers, and evaluated the telephone- based support program. Possible negative effects of the intervention were assessed. An in-depth assessment of maternal perspectives of the program at 12 weeks postpartum was performed. Conclusions: The 4-phase, 12-step approach delineated in this paper provides clear and concise guidelines for health professionals to follow in creating and implementing community-based, peer-support interventions with the potential to prevent PPD.
