AIDS
This study suggests that a web-based intervention with a harm reduction approach can enhance the self-efficacy of MSM in refusing risky sexual behaviors and chemsex and improve HIV testing in the 3-month follow-up interview. We also provide initial evidence that such interventions can reduce both the intention of MSM to engage in chemsex and their actual engagement in chemsex.The study was sponsored by the Council for the AIDS Trust Fund (reference number: MSS 338 R).This HIV/AIDS prevention part of the project/program is sponsored by the AIDS Trust Fund.
