Note. Abbreviations: BDI = Beck Depression Inventory; CADSS = Clinician‐Administered Dissociative States Scale; CAPS = Clinician Administered PTSD Scale; CTQ = Childhood Trauma Questionnaire; MDD = Major Depression Disorder; MDI = Multiscale Dissociation Inventory (Dep = Depersonalization Subscale; Der = Derealization Subscale; Dep/Der = Depersonalization and Derealization Subscales Averaged); RSDI‐Diss = Responses to Script Driven Imagery Scale – Dissociation Subscale; STAI = State‐Trait Anxiety Inventory.
Age, sex, and trait scores (CAPS total, Caps 5, CTQ, BDI, MDI (total, Dep, Der, Dep/Der)), state scores (RSDI‐Diss, STAI, CADSS), and MDD status reported for all sample groups (PTSD + DS, PTSD, healthy controls) as mean values plus/minus standard deviations.
