Abstract

APP+ is a theoretically-grounded mobile app intervention to improve antiretroviral (ART) adherence among men who have sex with men (MSM) who use stimulants. We assessed the feasibility and acceptability of APP+ in a six-month randomized controlled trial among a national sample of 90 MSM recruited online; secondarily, we examined changes in self-reported ART adherence by study arm. Retention at the final assessment was 82%, and acceptability ratings were comparable to other technology-based interventions. MSM in the APP+ group reported higher self-reported percentage ART adherence in the past 30 days at the four-month timepoint compared to a no-treatment control group (89.0% vs. 77.2%). However, once access to the app was removed after month four, group differences in ART adherence diminished by month six. APP+ may be a potentially promising intervention approach for MSM living with HIV who use stimulants but would require enhancements to optimize acceptability and demonstrate more sustained effects.
