This second edition updates and expands the pioneering work of Enright and Fitzgibbons, with new case studies, new empirical evaluation, modern philosophical roots of forgiveness therapy, and new measurement techniques. Benefitting from over 13 years of new research, Forgiveness Therapy features: new case studies; new empirical evaluations; new measurement techniques; and new chapters on the lasting legacy of those who enter forgiveness therapy and on forgiveness education for children and adolescents. The significant development of forgiveness therapy and greater understanding of the role of excessive anger in mental health disorders make this book a vital tool for clinicians.
