The Finnish version of the Dissociative Experiences Scale-II (DES-II) and psychiatric distress.
The confirmatory factor structure of the Finnish version of the Dissociative Experiences Scale II (DES-II) was exactly the same in the non-clinical population (n=924) as was found in the most recent study in the USA (with the original English version) and as suggested by the authors of the original version. The Finnish version of the DES-II has a Cronbach's alpha of 0.92, and there is a clear positive correlation (from 0.31 to 0.66) between all 28 items and the total score (P<0.001 for all items), indicating good internal consistency and reliability. We also investigated dissociative experiences and psychiatric distress with the DES-II and the General Health Questionnaire (GHQ-12). The increased proportion of "pathological dissociation" (DES-T) to "non-pathological dissociation" (DES-NP) was directly linked with increased distress. This finding is meaningful for the debate on the utility of the different DES-II scoring systems.
