This book series will offer original contributions to current books available on this fast growing area of high public interest. Each volume will comprehensively engage with current literature and make efforts to access unpublished literature and data by key authors in the field. The series will also, by the end of each volume, suggest potential new directions for researchers and practitioners. These volumes are relevant not just to psychologists, criminologists, social workers, final year undergraduate, postgraduate, doctoral students of all these areas, but to practitioners and the general public with an interest in learning more about the topic. The aim is to create books that are readable, yet firmly anchored in a sound evidence base from both researchers and practitioners. The volumes will include therefore a robust synthesis of the literature, consideration of the theories relevant to each topic, a focus on projects that are relevant to the topic, with a summary of the research and evaluation of these chapters focusing on the service user voice and a final summary chapter, highlighting future possibilities and directions (as suggested by others in the field or by the authors themselves).
