| Abstract: | The newly developed Dissoziations-Spannungs-Skala (Dissociation Tension Scale; DSS) is a self-rating instrument for the assessment of psychological and somatoform dissociative features (ranging from normal up to pathological) as well as aversive inner tension occurring within the past 7 days. The DSS contains 21 items assessing dissociative symptoms and 1 additional item assessing aversive inner tension. Ratings are made on a time-oriented scale ranging from 0% (never) to 100% (constantly). We measured the psychometric qualities of the DSS in a total of 294 patients and healthy controls. Internal consistency of the DSS was high (Cronbach's α = .92; Gutmann's split-half r = .92). We found good support for convergent, discriminant, and differential validity. There was clear evidence for the DSS being a sensitive instrument for the assessment of changing symptomatology. Assessment of dissociation and other psychopathological features over the same period of time are now possible. |
