A resurgent stimulant epidemic among men living with HIV could compromise the U.S. Ending the HIV Epidemic goals by interfering with HIV care engagement, adherence, and virologic suppression among men living with HIV. Prominent multi-level factors interfere with HIV virologic suppression for men living with HIV, particularly among those who use stimulants. This study is a nested randomized clinical trial to test a multi-component intervention to improve virologic suppression, adherence, and stimulant use among men living with HIV who use stimulants. The intervention, known as reSTART, will combine an evidence-based positive affect mobile health (mHealth) intervention, a home-based urine point-of-care test for adherence self-monitoring, and motivational interviewing and messages. The goal of the reSTART intervention is to improve or maintain adherence to HIV medications and reduce stimulant use. By this high-impact study's end, the investigators will have identified the impact of a multi-component reSTART mHealth intervention using novel point-of-care adherence self-monitoring on HIV virologic suppression and stimulant use.
