Sport-based crime prevention programmes are becoming increasingly popular worldwide but until now there has been very little research on the effectiveness of such approaches. Bringing together authoritative evidence from existing programmes, the authors identify and analyse emerging successful practices. Covering mentoring and coaching, particularly as they relate to Positive Youth Development (PYD) programmes, the authors explore how the development of core life skills can improve individual resilience and decrease the risk of criminal involvement. The book conceptualizes the links between criminological theory and PYD and gives recommendations for future policy and practice.
