In the first part of the paper, the theory of DBR is briefly discussed in relation to the development of DID, a condition where severe relational trauma and adjacent childhood traumatisation is hypothesized to be connected to the development of the symptomatology. In the second part, two single-case studies with two DID-clients diagnosed with SCID-D aim to provide initial evidence of how clients with DID experienced and responded to DBR therapy as part of longer phase specific therapies. The client of case I was treated with 30 DBR sessions and the client of case II was treated with 70 DBR sessions. Their pre- and post-DBR treatment measures consisted of instruments to measure PTSD and complex PTSD symptoms, psychoform and somatoform dissociation, general symptomatology, and access to positive states of mind. The outcome measures were assessed through percentage of nonoverlapping data (PND) a nonparametric measure used to assess the effectiveness of interventions in single-case experimental designs (SCEDs).

For client II the measurements on PCL-5, SDQ-5 and SCL-90-R were significantly lowered. Their self-assessed positive states of mind, measured with the PSOM-scale, were heightened. Both clients expressed that DBR was a valuable treatment modality through their summarized verbal and written statements.</div></div><div><h3>Conclusions</h3><div>After 30 respectively during 70 DBR sessions, the clients' dissociation and comorbid symptoms decreased significantly, as measured by self-assessments measures and analysed with PND.
