A project of the Campbell Collaboration Crime and Justice Group, Preventing Crime brings together the leading scientific evidence on what works best for a wide range of interventions organized around four important domains in criminology: at-risk children, offenders, victims, and places. It is the first book to assess the effectiveness of criminological interventions using the most rigorous review methodology of the systematic review. It is an indispensable guide to the leading scientific evidence on what works best to prevent crime.
