This book offers criminologists and students an evidence-based discussion of the latest trends in corrections. Over the last several decades, research has clearly shown that rehabilitation efforts can be effective at reducing recidivism among criminal offenders. However, researchers also recognize that treatment is not a "one size fits all" approach. Offenders vary by gender, age, crime type, and/or addictions, to name but a few, and these individual needs must be addressed by providers. Finally, issues such as leadership, quality of staff, and evaluation efforts affect the quality and delivery of treatment services. This book synthesizes the vast research for the student interested in correctional rehabilitation as well as for the practitioner working with offenders. While other texts have addressed issues regarding treatment in corrections, this text is unique in that it not only discusses the research on "what works" but also addresses implementation issues as practitioners move from theory to practice, as well as the importance of staff, leadership and evaluation efforts.
