[Development and characteristics of Dissociation-Tension-Scale acute (DSS-Akute)].

The Dissociation-Tension-Scale acute (DSS-acute) is conducted as a self-rating instrument to assess present-time dissociative features. In addition, the level of aversive inner tension is assessed. The study validates the psychometric quality of the DSS-acute. The sample included 195 female probands. Internal consistency is high (Cronbach's alpha = 0.94). The same is true for split-half reliability according to Gutmann (r = 0.93). The DSS-acute correlates high with scales assessing similar constructs but differs from global scales. The DSS-acute discriminates well between different diagnostic groups. There exist first evidences for being a sensitive instrument for assessing changing symptomatology. The DSS-acute is a reliable and valid instrument to assess present-time dissociative experiences as well as aversive inner tension. Current studies should further proof the sensitivity for changing symptomatology.
