“Psychological Research in Prisons provides an impressive collection of accessible and informed chapters, each highlighting the extent to which psychological theory and research can inform the work of practitioners, and how practice can influence the direction of research.” Julie Harrower, Chartered Forensic Psychologist, Head of Psychology at Coventry University and Chair of the DFP Board of Examiners “Psychological Research in Prisons contains some new and interesting empirical results. But its main achievement is to put the question mark firmly back into ‘What works?’ Early chapters explore how, often tentative, research findings about interventions which might reduce reoffending have become translated into overly prescriptive policies that actually serve to undermine rather than foster effective practice. This is a book by psychologists but its readership should be much wider – policy makers, prison governors, probation and prison staff, and criminologists will all find much food for thought within its pages.” Professor Carol Hedderman, University of Leicester “It is sure to become a new standard reference book in this field. It will be a very useful aid to the work of psychologists in Japan, who are currently introducing CBT within custodial settings.” Hiroshi Urata, Senior Psychologist, Wakayama Juvenile Classification Home, Japan
