The patient improved in several domains: she experienced a reduction of PTSD symptoms, as well as dissociative symptoms, there were structural changes in the beliefs about the self, and loss of suicidal behaviors. She received 220 sessions of ST, which included direct trauma processing through Imagery Rescripting (ImRs). The presented case concerns a 43-year-old female patient with DID, depressive disorder (recurrent type), PTSD, cannabis use disorder, and BPD. This case report presents an overview of the protocol adaptations for DID ST treatment. This approach is currently being investigated in several studies and has the potential to become an evidence-based treatment for DID. Schema Therapy (ST) is an integrative psychotherapy that has been proposed as a treatment for DID. The percentage of patients that reach the third phase is relatively low, treatment duration is long, and the effects of this treatment on the core DID symptoms have been found to be small or absent, leaving room for improvement in the treatment of DID. Treatment for Dissociative Identity Disorder (DID) often follows a practice-based psychodynamic psychotherapy approach that is conducted in three phases: symptom stabilization, trauma processing, and identity integration and rehabilitation. 5Department of Experimental Psychotherapy and Psychopathology, University of Groningen, Groningen, Netherlands.4Department of Clinical Psychology, University of Amsterdam, Amsterdam, Netherlands.3Department of Clinical Psychological Science, Maastricht University, Maastricht, Netherlands.2GGZ-Oost Brabant, Department of Personality Disorders, Helmond, Netherlands.1Department of Medical and Clinical Psychology, Tilburg University, Tilburg, Netherlands.
