Trauma Model Therapy for Trauma, Dissociation, and Complex Comorbidity


In this workshop, Dr. Ross will explain the principles of his Trauma Model and the relationships between trauma, dissociation and comorbidity within the model. The Trauma Model is a detailed, scientifically testable theory about the relationships between trauma and a wide range of mental disorders and addictions. He will review treatment outcome data from his Trauma Program. Dr. Ross will then explain the principles of Trauma Model Therapy, which sits on the foundation of the overall Trauma Model. These include: the problem of attachment to the perpetrator; the locus of control shift; the problem is not the problem; just say ‘no’ to drugs; addiction is the opposite of desensitization; and the victim-rescuer-perpetrator triangle. He will then describe core principles of the therapy of DID including: the central paradox of DID; the problem of host resistance, talking through to alter personalities; orientation to the body and the present; deprogramming without deprogramming; making friends with Satan; the principle of therapeutic neutrality; and levels and layers in the system. The workshop will be practical and hands-on with many examples of specific techniques and strategies.

This session was originally presented as a live conference session in June 2020.
