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.

Abstract

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. 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. 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 5years (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). 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.
