[The validity of the depersonalisation-derealisation scale of the narcissism--inventory].
The German Narcissism-Inventory contains a 6-item scale for the assessment of depersonalization (DP) and derealization (DR). The validity of this scale (NI-DRP) was examined in comparison to the German version of the Dissociative Experiences Scale (FDS) and the Cambridge Depersonalization Scale (CDS). The sample consists of 144 psychotherapy patients, of whom showed on the basis of a structured clinical interview n = 51 none, n = 45 mild, n = 28 moderate and n = 20 severe DP-DR. The areas under the curve and the rate of misclassification did not differ for NI-DRP and the scales of the FDS. The CDS showed the lowest rate of misclassifications.
