Abstract
Over the last two and a half decades, researchers and public health agencies have invested substantial resources in developing and implementing counselling and behavioural interventions to decrease HIV transmission among men who have sex with men (MSM) in higher-income nations. Meanwhile, MSM have substantially altered their sexual risk behaviour, adapting to the HIV epidemic, as well as the technological revolution fuelled by the Internet. This presentation will review the evidence supporting the efficacy of behavioural interventions in MSM, discuss the challenges posed in bringing those interventions to scale, and suggest future research and prevention directions designed to move behavioural interventions from an efficacy to an effectiveness focus.
