This collection of research and evaluation explores issues in mental health and probation across the globe. The volume offers insight into a wide range of interrelated topics that address the mental health and mental health needs of those under probation supervision. The chapters embrace a range of diverse mental health concerns. The underpinning assumption is that offenders should receive mental healthcare that is 'equivalent' to that received by the general population where this is appropriate. This overview is informed by perspectives from academics and practitioners based in England and the Republic of Ireland, and also includes the views of people with lived experience of the Criminal Justice System. Building upon and adding to the existing literature in this field, the book will be a valuable resource for academics and researchers as well as those training to work in, and currently working in, the criminal justice and mental health field, and would also be of interest to those working in related healthcare settings.
