A Pilot Randomized Control Trial of the Motivational Interviewing to Increase PrEP Uptake Intervention Among Black Women in the United States.

Abstract

Despite the disproportional impact of HIV, Black individuals are benefiting the least from pre-exposure prophylaxis (PrEP). Motivational interviewing (MI) for PrEP uptake (MI-PrEP) is a two-session culturally tailored intervention incorporating MI strategies to improve PrEP motivation and uptake among cisgender Black women. A pilot randomized control trial was conducted in the Southeastern United States, and 41 women were randomized to MI-PrEP (session 1 with PrEP psychoeducation and MI and session 2 with MI and light case management) or enhanced treatment as usual (ETAU; two sessions of PrEP psychoeducation [videos explaining PrEP]). Women completed one follow-up assessment (1 month after visit 2). Measures captured primary (motivation [via contemplation and readiness ruler] and PrEP uptake via medical records) and secondary outcomes (e.g., PrEP knowledge, barriers to PrEP, and speaking to a provider about PrEP). Difference-in-differences analyses comparing MI-PrEP with ETAU as well as t-tests for within-group changes over time were conducted. Women who completed MI-PrEP (90.5% retained) compared with ETAU (100% retained) had a significantly higher likelihood of speaking to a provider about PrEP (OR = 4.42e7, CI [8.55e6, 2.29e8], DiD = 17.60, se = 0.84, p < 0.001). Within the MI-PrEP group, women had significant increases in PrEP prescription, knowledge, and motivation/contemplation, and significant decreases in financial resources as a PrEP barrier and medical mistrust (MMT). ETAU had within-group increases in PrEP prescription and speaking to a provider, no changes in motivation and MMT, and increases in specific barriers to care (e.g., transportation). MI-PrEP shows promise, and a large-scale study may be beneficial to further assess efficacy and examine implementation.
