The last few years have seen a marked change in attitudes to the rehabilitation and management of offenders. It is now impossible to ignore evidence which demonstrates the possibilities for reducing reoffending. This book assembles and consolidates that evidence, and indicates the implications for both practice and research. Professionals in probation, parole and law, as well as in forensic psychology, psychiatry, nursing, and prison management and policy, will find this book of direct relevance to their work and thinking. It will be of interest and value to practitioners, academics and researchers across the whole field of adult and juvenile criminal justice. A key emphasis of the book is the relationship between research and practice: the evidence presented here constitutes a significant advancement in knowledge in the social sciences generally, and the findings are of considerable practical importance, in providing guidelines of relevance to practitioners and policy-makers throughout the criminal justice system.
