The mission of the Campbell Crime and Justice Coordinating Group (CCJG) is to coordinate, facilitate, assist and encourage the production, updating and accessibility of high quality systematic reviews.
These reviews of research on the effects of criminological and criminal justice interventions are developed to inform criminal justice policies, to reduce crime and increase justice in society.
The CCJG prepares systematic reviews on the effects of interventions
- aimed at the prevention, treatment or control of crime or delinquency.
- designed to improve the criminal justice system, including those relevant to forensics, police, courts, prison, probation, etc.
- within both civil and criminal law.
Our principles
We are committed to the following principles:
- To prepare rigorous systematic reviews of high-quality evaluations.
- To update those reviews periodically to take into account new studies, criticism and methodological advances.
- To disseminate the reviews electronically to ensure rapid and widespread access.
- To use search strategies that ensure that all high-quality studies are taken into account.
- To collaborate internationally to ensure worldwide coverage of the literature and the translation of review results into multiple languages.
- To establish a multi-national and multi-interest editorial board so that reviews are relevant and written in an accessible way.
- To maintain open processes to enable users to understand and criticize decisions made at each stage of the process.
- To create an accessible register of evaluation studies as a resource to reviewers and others.
