CDS
Cambridge Depersonalisation Scale - deutsche Fassung (Trait-Version)
Short abstract
The German version of the CDS measures the core symptoms of depersonalisation-derealisation syndrome in terms of their frequency and duration. The CDS contains the translated 29 items of the English original version as well as an item supplemented by the German authors, which, however, is not included in the routine evaluation. The symptoms described in the items are assessed with regard to their frequency in the last 6 months and their respective duration. On the basis of a canonical discriminant function, the nine most differentiating items were determined and compiled into the short scale CDS-9. Reliability: Cronbach's alpha was at alpha = .95, for the short scale at alpha = .92. After an interval of 10-14 days, a retrestreliability of rtt = .89 for the CDS and rtt = .86 for the CDS-9 was found. Validity: Correlation analyses revealed significant correlations between the CDS and the scales of the questionnaire on dissociative symptoms (FDS). In addition, CDS was able to differentiate well between groups who had been diagnosed as patients with or without pathologic depersonalization using the Structured Clinical Interviews for DSM-IV Dissociative Disorders (SKID-D).
