Book excerpt: Time does not heal all wounds: decades after a disaster, entire communities may still experience the long-term effects of trauma. Sociodrama and Collective Trauma examines the psychological and social damage of trauma to society as a whole. Kellermann argues that collective trauma has been insufficiently considered; his timely book suggests practical ways of facilitating the rehabilitation of survivors of collective trauma through, for example, sociodrama and related group work. The author develops methods for understanding the past and preparing for the future and provides a wealth of case studies based on 30 years' experience of treating survivors of war trauma and other forms of disaster. Combining a systematic theoretical approach with a practical methodology, this insightful book is invaluable for drama therapists, group therapists, mental health professionals and counsellors.
