Traumatic stress is an important and diverse area of research and practice that crosses disciplines including psychology, psychiatry, and cognitive behavioural psychotherapy. The literature on the topic which has emerged over the last 50 years spans a large number of fields and journals. This major work performs the services of bringing together these disparate but vital strands of research into a single publication. Edited and introduced by esteemed Editor, Michael J. Scott, the literature is arranged into four thematic volumes, designed to guide the reader through key developments in the field and provide them with a comprehensive overview. Volume One: Introduction, History, Context Volume Two: Approaches to The Treatment of Trauma Related Disorders Volume Three: The Management of Secondary Traumatisation and Comorbidity Volume Four: Translating Evidence Based Treatment to Routine Practise
