Applying a mutual capacity building model to inform peer provider programs in South Africa and the United States: A combined qualitative analysis.

Background: Globally, there is a treatment gap for substance use treatment and harm reduction services. As peer-delivered interventions expand to address this gap in both high-income countries (HICs) and low and middle-income countries (LMICs), they provide an opportunity to examine mutual capacity building, the bidirectional exchange of ideas between distinct settings to address common challenges.

Methods: The aim of this study was to explore the perspectives of patients in Cape Town and Baltimore about the acceptability and feasibility of a peer-delivered intervention using a combined qualitative analysis across a HIC and LMIC. Semi-structured qualitative interviews were conducted with participants in pilot trials in Cape Town, South Africa and Baltimore, USA (n=55). Across both trials, participants received a peer-delivered behavioral intervention focused on problem solving strategies for medication adherence, behavioral activation, and other cognitive-behavioral skills. The datasets from each location were merged and analyzed jointly using thematic analysis to develop codes and themes. Transcripts were coded to theoretical saturation (n=21 from Baltimore, n=16 from Cape Town).

Results: Participants highlighted what they valued about the peer-delivered intervention: 1) behavioral skills learned, 2) relationship with the peer, 3) ability to help others based on what they learned, 4) improved adherence to HIV or substance use medications, and 5) changes in substance use behaviors. In Baltimore, participants were typically more focused on their supportive relationship with the peer, which contrasted with many other relationships in their lives. In Cape Town, many participants highlighted the value of the skills they learned, such as mindfulness and activity scheduling.

Conclusions: Across sites, participants valued that the peer could support them to accomplish meaningful life goals beyond substance use recovery, such as building relationships or health. Differences between settings may highlight the importance of tailoring peer interventions to fill context-specific gaps in available services.
