In the 100 years since Eugen Bleuler unveiled his concept of schizophrenia, which had dissociation at its core, the essential connection between traumatic life events, dissociative processes and psychotic symptoms has been lost.

"Overall, the book suggests an exciting, more integrated perspective on understanding psychopathology. Well written, thought provoking and intellectually challenging, it serves to question current approaches to our patients and outlines the need for arguably very different styles of working in the future." (International Journal of Culture & Mental Health, 27 May 2011) "Editors Andrew Moskowitz, Ingo Schafer, and Martin J. Dorahy have amassed contributions from eminent scholars around the world who undertake a serious and thoughtful exploration of the backgrounds, development, and overlaps in the different perspectives of how the mind is disrupted by psychosis and dissociation ...Taken together, these papers demonstrate the complexity and depth of our understanding to date. Psychosis, Trauma and Dissociation: Emerging Perspectives on Severe Psychopathology is a rich resource to return to again and again. I recommend it for those who enjoy the challenge of reading some of the best thinkers to date. " ( Journal of Trauma and Dissociation , October 2010) "This book is an excellent source book for historians, researchers and clinicians in the field of psychiatry interested in learning more about how the concepts of dissociation, trauma and psychosis inform one another." ( Psychiatric Rehabilitation Journal , January 2010) "This very interesting book not only connects traumatic experiences with dissociative and psychotic consequences, but clarifies the research into the nature of these links." ( Psychosis , July 2009) "This useful and interesting book is well written and lays out its arguments for the connections between trauma/dissociation/psychosis clearly and cogently." ( Doody's , April 2009)
