Effectiveness of behavioural and psychosocial HIV/STI prevention interventions for MSM in Europe

Literature review Technical report

In Europe, men who have sex with men (MSM) continue to be the population most affected by HIV, and the rate of infections is increasing faster among MSM than among other populations. Behavioural and psychosocial prevention with the goal of limiting sexual risk behaviours remains central to the efforts to decrease sexual HIV/STI transmissions among MSM.This report consists of a systematic review that updates the current knowledge base about HIV/STI preventive interventions targeted at MSM in Europe. It summarises and assesses the effectiveness of these interventions and identifies intervention characteristics associated with effectiveness, as well as potential gaps, in the evidence base.
