Who could benefit from this research
✓Could help
MSM who engage in chemsex and own a smartphone with internet access in Malaysia.
✕Less likely to help
MSM who do not use smartphones or are not at risk for chemsex-related harms.
What this research studies
This project uses a micro-randomized trial to deliver context-driven prompts and resources through a smartphone app to MSM who engage in chemsex. The goal is to find when and how to push harm-reduction help so it fits naturally into users’ real-life moments. It targets spontaneous risk periods and aims to minimize burden while maximizing willingness to engage with proven harm-reduction strategies. The study is conducted among Malaysian MSM and will inform scalable digital interventions for reducing HIV transmission in this population.
Why it matters
Potential benefit: If successful, the app could provide timely, tailored support that reduces risky chemsex behaviors and lowers HIV transmission risk.
How similar studies have gone: Prior JITAI work shows promise in other health areas, but this is among the first to apply JITAI for chemsex harm reduction.
