Smartphone support to reduce chemsex harms for men who have sex with men

Optimizing a Just-in-Time Adaptive Intervention to Increase Uptake of Chemsex Harm Reduction Services in MSM: A Micro-randomized Trial

NIH-funded research University of Connecticut Storrs · NIH-11380030

This project uses a smartphone app to send timely, personalized messages and links to harm-reduction services to help men who have sex with men stay safer during chemsex.

What this research studies

You would use an app called JomCare that detects moments of higher chemsex risk and offers short, private tips, safety tools, and service links. The app delivers tailored messages at key times and the study will sometimes try different messages or features to see which work best. Participants are repeatedly and randomly offered different app components so researchers can learn which timing and content reduce risk most effectively. The project focuses on men who have sex with men in Malaysia and aims to provide low-burden, discreet support.

Who could benefit from this research

Good fit: Ideal candidates are men who have sex with men who engage in chemsex, live in Malaysia, and can use an Android smartphone to run the JomCare app.

Not a fit: People who do not engage in chemsex, live outside the study area, or cannot use the required smartphone app are unlikely to benefit directly.

Why it matters

Potential benefit: If successful, this could lower HIV transmission and other harms by connecting MSM with timely, private harm-reduction support when they need it.

How similar studies have performed: Similar just-in-time adaptive intervention apps have helped with addiction and mental health, but using them specifically for chemsex harm reduction is novel.
