Baseline Survey in ATN 141 - MyChoices Mobile-Based Application to Increase Uptake of HIV Testing, Detection of New HIV Infections, and Linkage to Care and Prevention Services By Young Men who have Sex with Men

Baseline survey SAS Study Description Based on extensive formative, community-engaged research and subsequent theater testing and an open technical pilot, we developed a theory-driven mobile app—MyChoices—to increase HIV testing and PrEP uptake among young men who have sex with men (YMSM), ages 15-24. In a pilot randomized controlled trial (RCT), YMSM at risk for HIV acquisition in the US (n=60) were randomized 2:1 to receive MyChoices or standard of care (SOC). Data from 3-month and 6-month post-baseline assessments demonstrate that the app was highly acceptable (System Usability Score; mean=75.8, SD=10.7) and feasible (94% used the MyChoices app at least once; mean=15.3 sessions, SD=9.8). While not powered to assess efficacy, those in the MyChoices arm had 22% higher prevalence of HIV testing over follow-up compared to those in the SOC arm (NS). There was no difference in PrEP uptake. HIV-uninfected men who have sex with men ages 15-24 years, assigned male sex at birth, and with self-reported evidence of high-risk for acquiring HIV infection were enrolled at three study sites in Boston, MA; Bronx, NY; and Chapel Hill, NC.
