ABSTRACT
Offending behaviour interventions are designed to prevent (or at least reduce) offending and reoffending by children and young people. Metaanalyses have determined a number of core principles that may make such programmes more effective. They suggest in particular that interventions that contain elements of cognitive behavioural and multi-systemic approaches can achieve significant effect sizes for recidivism. In addition, they highlight a number of interventions that are less likely to work overall.
