Assessing the Preliminary Efficacy of a Nonrandomized, Clinic-Based HIV Risk Reduction Pilot Intervention for PrEP-Initiated, Alcohol- and Other Drug-Using Women of Color in Miami, FL

Abstract

AbstractIn this paper, we assessed the preliminary efficacy and acceptability of a quasi-experimental, clinic-based sexual risk reduction pilot intervention for pre-exposure prophylaxis (PrEP)-initiated, alcohol- and other drug-using women of color and explored their self-reported barriers to, and facilitators of, PrEP use. Using a mixed methods design, analyses incorporated pre- and post-intervention study assessment data from 38 women and semi-structured process evaluations using a subsample of 25. The intervention administered over an 8-week period consisted of 4 one-on-one in person educational sessions, a process evaluation, and study assessments conducted at baseline and 3 and 6 months. Post intervention, statistically significant changes in sexual risk scores were not observed; however, we found significant decreases in alcohol use (Z =  − 3.02, p = .003, η2 = .41). Process evaluation data revealed interpersonal relationships as a key motivator for PrEP initiation as well as a prominent barrier to PrEP use; these relationships rarely facilitated adherence. Overall, women found the intervention to be acceptable and reported a wide range of benefits of participation—most notably its therapeutic benefits. Findings from this study provide preliminary evidence of the potential for the Talking PrEP with Women of Color intervention to improve risky behaviors, knowledge, and attitudes related to sexual risk taking. Furthermore, findings suggest that interventions to increase PrEP uptake and adherence in at-risk women may benefit from supporting them in accurately estimating their risk for HIV and increasing their sense of social support.
