Design outcomes

Primary

Measure	Time frame
The main study parameter will be the Dissociation process scale, which is a ten-item self-report questionnaire comprising the SDQ-5 and five questions on dissociative experiences during the previous 24 hours (see for further information section Study procedures). We will base our main conclusions on the change in score on the Dissociation process scale over the four phases within subjects.	—

Secondary

Measure	Time frame
The following secondary study parameters will be measured: 1. Dissociative symptoms, measured with the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D), Dissociative Disorders Interview Schedule - Self report version (DDIS-SR), Dissociative Experiences Scale (DES-II) and the Dissociation Tension Scale (DTS) - the DES-II questionnaire is already part of TAU 2. Detachment and compartmentalization, measured with the Detachment and Compartmentalization Inventory (DCI) 3. Beliefs about functioning of memory, measured with the Dissociative Beliefs about Memory Questionnaire (DBMQ) 4. PTSD symptoms, measured with the Dutch version of the Clinician-Administered PTSD Scale (CAPS-5) and the PTSD Checklist for DSM-5 (PCL-5) - both are already part of TAU 5. Depressive symptoms, measured with the 16-item Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) 6. Suicidality, measured with the Suicidal Ideation Attributes Scale (SIDAS) - the SIDAS is already part of TAU 7. Self-harm behaviors, measured with the first item of the Inventory of Statements about Self-injury (ISAS) 8. Emotion regulation problems, measured with the Difficulties in Emotion Regulation Scale (DERS) 9. Assertiveness, measured with the Assertion Inventory (AI) 10. Patients* opinions on the function of their fragmented identities and the treatment, measured with several open questions (see for further information section Study procedures) 11. Drop-out percentage	—
