Is this trial a fit for you?
✓Likely a good fit
Adults (18+) in Thailand who are men who have sex with men, transgender women or men, or non-binary people who have engaged in chemsex or substance use in the past 12 months and can provide informed consent in Thai.
✕Probably not a fit
People who cannot communicate in Thai, are younger than 18, or have not engaged in chemsex or recent substance use are unlikely to benefit from this project.

What this trial studies
This is a sequential exploratory mixed-methods implementation project at the Institute of HIV Research and Innovation clinics in Bangkok. The work begins with qualitative interviews to adapt the 'Pleasuremeter' tool and then integrates the tool into harm reduction service encounters. About 300 participants will be enrolled and followed at baseline, month 3, and month 6 to track sexual pleasure, behavioral risk, substance use, HIV/STI testing, mental health, and socio-legal factors. The study also measures acceptability, satisfaction, and feasibility of using a pleasure-based approach in existing services.
Why it matters
Potential benefit: If successful, this approach could improve engagement with harm reduction services, increase HIV/STI testing and safer behaviors, and better address sexual wellbeing for MSM and transgender people who do chemsex.
How similar studies have gone: Pleasure-focused sexual-health approaches are relatively novel; while some behavioral harm-reduction programs for people who use drugs have shown benefits, integrating a 'Pleasuremeter' into clinical services in this population and setting is largely untested.
