PrEP Communication Intervention for Female Clients of a Needle Exchange

Development and Pilot Testing of a PrEP Communication Intervention and Integration Into Existing HIV Testing Services for Female IV Drug Using Clients of a Needle Exchange

This study will identify perceptions of PrEP in women who inject drugs (WWIDs) and develop and pilot test a targeted intervention that will be embedded in a large, urban syringe exchange program through an extensive formative evaluation process. Using perceptual mapping, an innovative marketing evaluation technique, WWIDs' PrEP perceptions will be incorporated into messaging in targeted counseling, materials, and text messaging to encourage PrEP adherence. This will then be tested in a pilot Randomized Controlled Trial (RCT) by comparing it to a general PrEP intervention to assess for uptake and adherence to PrEP, as well as improved self-efficacy and lower decisional conflict.

Women who inject drugs (WWIDs) are at significantly higher risk of contracting HIV due to both needle sharing and sexual behaviors, yet utilize HIV prevention resources less. Analysis of studies testing pre-exposure prophylaxis (PrEP) has not tested effectiveness in WWIDs and little research exists on their specific barriers to uptake and adherence. The result is a significant group who is highly vulnerable to HIV infection and its negative health consequences, yet is less likely to benefit from PrEP. To address this gap this study will use a rigorous formative evaluation strategy utilizing a unique and innovative marketing evaluation technique. Using perceptual mapping and vector modeling analysis, the investigators will develop 3-D maps to identify specific message strategies to embed into an intervention using targeted PrEP counseling, written materials, and text based messaging and pilot tested for promise of efficacy compared to a general PrEP intervention. The intervention will address psycho-social barriers to PrEP through perceptual mapping but also societal and structural barriers by embedding it in a trusted syringe exchange and distributing medication through its medical clinic. Specific aims of the research are: 1. Assess WWIDs' perceptions of PrEP and potential barriers to use. To accomplish this the investigators will conduct focus groups (n=30) and interviews with syringe exchange staff (n=10) and develop a perceptual mapping survey. 2. Develop a targeted communication intervention based on vector modeling findings, including print materials, PrEP counseling, and text messages, and assess feasibility and acceptability. To accomplish this the investigators will conduct perceptual mapping surveys with HIV- WWIDs (n=100), do vector modeling analysis and create sample messages, concept test messages with WWIDs and staff (n=20), create intervention materials and conduct usability testing (n=20). 3. Pilot test the intervention by integrating into a syringe exchange to assess promise of efficacy. To accomplish this the investigators will conduct a randomized pilot (n=50) and test an "enhanced" intervention using targeted messages with a "basic" intervention that provides general PrEP counseling. To assess promise of efficacy the investigators will compare PrEP adherence (blood test; self report) and differences in PrEP attitudes, self-efficacy, and decisional conflict.
