Bio Onno van der Hart, Ph.D.

Onno van der Hart offers training and consultation of trauma-related dissociation and the dissociative disorders. Emeritus Professor of Psychopathology of Chronic Traumatization at the Department of Clinical and Health Psychology at Utrecht University, the Netherlands, he has been a psychologist/psychotherapist at several mental health centers.

He has been on the Editorial Board of a number of scientific journals, and he has published several books in the area of trauma and dissociation, loss, and bereavement, and over 100 articles in peer-reviewed scientific journals (several of which can be found at this website). Onno van der Hart is a Past-President of the International Society for Traumatic Stress Studies and Fellow of the American Society of Clinical Hypnosis (ASCH). He is a scholar in Pierre Janet studies, exemplified by the publication of Giseppe Craparo, Francesca Ortu, & Onno van der Hart, O. (Eds.) (2019). Rediscovering Pierre Janet: Trauma, dissociation, and a new context for psychoanalysis. London & New York: Routledge.

Onno van der Hart has worked with colleagues Ellert Nijenhuis, PhD, and Kathy Steele, MN, CS, on a theoretical approach on trauma-related dissociation of the personality and a treatment model which unifies psychiatric disorders with a traumatic stress origin. Their combined efforts resulted, among other things, in the publication of their book, The haunted self: Structural dissociation and the treatment of chronic traumatization (New York/London: W.W. Norton & Cie, 2006), for which they received the Media Award of the International Society for the Study of Trauma and Dissociation (ISSTD). A related book is Coping with trauma-related dissociation: Skills training for patients and therapists, by Suzette Boon, Kathy Steele and Onno van der Hart (New York/London: W. W. Norton & Co), for which the authors received the ISSTD 2011 Pierre Janet Writing Award for best writing on dissociation. A more recent related publication is: Kathy Steele, Suzette Boon, and Onno van der Hart Treating trauma-related dissociation: A practical, integrative approach (New York/London: W. W. Norton & Cie, 2017), for which the authors received the ISSTD 2017 Pierre Janet Writing Award.
