Beyond-66: A pilot evaluation of a novel, peer-led harm reduction intervention for chemsex dependant men who have sex with men in Kuala Lumpur, Malaysia

BACKGROUND: There is little research exploring harm reduction interventions for men who have sex with men (MSM) who engage in chemsex. Beyond-66 is a novel, 132-day, peer-led intervention programme for MSM who are chemsex dependent in Kuala Lumpur, Malaysia. We aimed to evaluate the feasibility, retention and effect of Beyond-66 on: abstinence from chemsex, motivation for abstinence, and mental wellbeing.

METHOD: We collected data on demographics, retention and completion and abstinence between January 2021-August 2023 in MSM using Beyond-66. Using 10-point Likert scales, we compared motivation to remain abstinent and mental wellbeing at the beginning and end of Beyond-66.

RESULTS: 25 MSM have either completed or dropped out/referred out of Beyond-66, 12/25(48%) were living with HIV and the median duration of chemsex use was 5 years (IQR = 4-6). 19 (76%) completed programme; 3 were referred out for a psychiatry assessment and 3 dropped out of the programme. 14 (74%) remain abstinent and 5 relapsed. The median motivation for abstinence scores for the 19 completers increased significantly between the pre-programme and post-programme period (7/10 (IQR = 4-8) to 9/10 (IQR = 5-10), p = .04) and the median mental health score (Likert score out of 10 where 10 is poor mental health) reduced significantly (5/10 (IQR = 4-7) to 2/10 (IQR 1-6), p = .008).

CONCLUSION: This pilot evaluation suggests that MSM using Beyond-66 experience high completion (76%) and abstinence (74%) rates and increased motivation for abstinence and mental wellbeing scores. Further research is needed to design, develop, and deliver peer led interventions for MSM who are chemsex dependant.
