Carried out by the Australian Instutute of Criminology for the Australian Sports Commission, this study identified more than 600 programs for young people in Australia that focused on sport and physical activity. The study conducted a postal survey of these youth programs to identify which program components led to successful interventions to reduce antisocial behaviour by youth, and also undertook case studies of some of the programs. Programs most commonly catered for youth at risk of or involved in drug use and crime (81% of programs), and more than half of all programs surveyed were also open to youth not at risk of antisocial behaviour.
