Dimensionality of dissociation in subjects with PTSD Academic Article uri icon


  • Dissociative symptoms are common in patients with Post-traumatic stress disorder (FFSD). The Dissociative Experiences Scale (DES) is a self-report measure that is often used to assess these symptoms quantitatively. The present study examined the factor structure of the DES in a sample of 129 male combat veterans with PTSD. Quantitative and conceptual criteria were used to select a four-factor solution. One of the subscaks (labeled Depersonalization/ Derealization) was consistent with a scale found in an earlierfactor analysis using a nonclinical subject sample. Three other factors included Memory Disturbance, Absorption, and Distractibility. While these scales are intercorrelated, they may measure conceptually distinct types of dissociative symptoms.
