PrEP Talk: PrEP Uptake With Young Black MSM and Their Close Friends

Description

Young Black men who have sex with men (YBMSM) face a disproportionate burden of HIV infection. Pre-exposure prophylaxis (PrEP) is an effective tool for protecting individuals from HIV infection. However, uptake has been relatively slow among YBMSM (5-10%). 8 There is an urgent need to develop and test interventions to increase PrEP uptake with YBMSM, which is consistent with NIH priorities to examine the use of biomedical interventions for HIV prevention with high risk populations.

Our prior research indicates that many YBMSM are considering using PrEP, but they are skeptical about taking a pill daily for HIV prevention. 5 YBMSM's willingness to use PrEP is affected by many factors such as PrEP literacy, their own perceived low risk for HIV, concerns about taking the pill and side effects, medical mistrust, concerns about cost, lack of social support for using PrEP, and PrEP-related stigma. Consistent with our prior research showing the powerful influence of close social network members on HIV-related health behaviors, we have found that close friends of YBMSM can strongly influence YBMSM's' motivation to use PrEP via conversations with each other.

Guided by peer influence theory, a motivational interviewing (MI) approach and prior research, the goal of the proposed research is to develop, manualize, and evaluate a culturally-congruent intervention, "PrEP-Talk," which aims to increase PrEP uptake and adherence among YBMSM. We propose that their close friends can apply positive peer influence about taking PrEP. Our research is based on exploring how using MI with YBMSM and their close friends may help to overcome barriers to PrEP uptake and adherence.

We designed a dyad-level intervention concept for PrEP-Talk that involves three interconnected components to increase PrEP uptake: 1) a "PrEP Counselor" (PC), in which information and guidance will be provided to YBMSM and a Close Friend they select to help address barriers to making an informed decision regarding PrEP uptake, (2) a Close Friend (CF), defined as someone with whom the YBMSM has discussed sexual health topics in the past year (but not had sex with in the past year), who is aware that he has sex with men, and who agrees to support his PrEP uptake goals by engaging in dyad-level sessions about PrEP uptake and adherence with their friend, and (3) training on PrEP supportive communication (PSC) in every day conversations between YBMSM and CFs. PSC is talk between CFs that is well-informed and non-judgmental about PrEP, in which YBMSM discuss the pros and cons of PrEP use, helping YBMSM overcome barriers to uptake. All three components address the mechanisms of change (barriers and facilitators such as PrEP-related stigma, medical mistrust, concerns about cost, etc.) that are related to PrEP uptake and adherence among YBMSM. Culturally congruent referrals and linkages will also be provided. The proposed study is built on the scientific premise that peers, especially close friends, have a strong influence on health behaviors, through their communication about attitudes toward health topics such as PrEP uptake.

Our research has shown that YBMSM's CFs are particularly helpful in facilitating decisions about PrEP through providing supportive communication and that using MI can lead to increased antiretroviral therapy (ART) adherence among Black people living with HIV. 1, 4-7 In our proposed intervention, the PC will work with the YBMSM and the CF as they grapple with concerns about PrEP before they decide to access a clinic. Building on our prior research and collaborations with key community stakeholders providing services to YBMSM and with research experts, we will develop and pilot test "PrEP-Talk," a brief 3-session, 4-week dyad-level intervention, with up to 3 booster sessions on PrEP adherence for any dyad in which the YBMSM index participant (IP) starts PrEP; the IP is the focus of the intervention. IPs randomized to the control will receive regular care. We will accomplish our goal with the following specific aims:

1. To develop and manualize "PrEP-Talk," which aims to increase PrEP uptake and adherence among YBMSM. This will be done through qualitative formative research (3 focus groups with 12-18 YBMSM and CF dyads, N=24-36); partnering with our community advisory board (CAB; comprised of individuals knowledgeable about HIV work with YBMSM); and field tests of the intervention with 5 YBMSM and CF dyads (N=10).
2. Examine feasibility, acceptability and indicators of preliminary efficacy of "PrEP-Talk" on PrEP uptake and adherence among YBMSM. This will be accomplished through a small-scale pilot randomized controlled trial (RCT) with 30 dyads (YBMSM and CFs) in the intervention and 30 dyads in the usual care control arm (N=120). We will conduct assessments of all participants (IPs and CFs) at baseline, 3-months and 6-months post-baseline. We will collect urine samples as a biomarker of PrEP uptake from all YBMSM IPs who report use of PrEP in both arms.

Our intervention may increase PrEP uptake and adherence among YBMSM, thereby helping to reduce HIV incidence and reducing a critical public health disparity. If the proposed intervention shows trends for feasibility, acceptability and indicators of preliminary efficacy for increasing PrEP uptake among YBMSM, we will pursue funding for a full-scale R01-funded RCT.
