What makes peers credible? A qualitative analysis to operationalize peer credibility in HIV-prevention and treatment programs for Latino MSM.

The potential of peers to be effective in delivering HIV interventions is linked at least in part to the degree to which they are perceived as credible sources of HIV-related information. This study aimed to operationalize qualities that would make a LMSM peer implementer credible. We conducted a qualitative analysis of semi-structured interviews with 20 LMSM and focus groups with 11 HIV service implementers. The parent study collected formative data to inform the design of a strategy to enhance the reach of HIV prevention and treatment services to LMSM. The present study examined participant views on qualities necessary for peer implementers to establish credibility among LMSM. We identified five themes regarding peer credibility, including (1) Peers must be trained in HIV prevention and care, (2) Peers should be verified and have a special designation indicating their knowledge and trustworthiness, (3) Peers should convey accurate information and not spread misinformation, (4) Peers should be relatable and interpersonally skilled, and (5) Peers should be engaged with the general LGBTQ + community to generate trust and credibility. Findings can inform the development of acceptable peer strategies for LMSM, peer recruitment, training, and peer supervision.
