Reducing gang related crime : a systematic review of ‘comprehensive’ interventions

The aim of this review was to find out if ‘comprehensive’ interventions are more effective at reducing gang related criminal activity and anti-social behaviour than usual service provision. This systematic review was published by EPPI-Centre in 2009. .Systematic reviews aim to find as much as possible of the research relevant to the particular research questions, and use explicit methods to identify what can reliably be said on the basis of these studies.
