Study design: Observational Study
Abstract: Investigators have described dissociative phenomena in post-traumatic stress disorder (PTSD) and, conversely, viewed dissociative disorders such as multiple personality disorder (MPD) as related to PTSD.However, no study has investigated the incidence ofdissociation or predictors ofa pre-existing dissociative disorder in a PTSD group using standardized measures ofPTSD and dissociation.This study examined dissociation and predictors of childhood dissociation in 35 PTSD Vietnam combat veterans.Subjects scored significantly higher than normals on the Dissociative Experiences Scale and Perceptual Alteration Scale.Construct validity of these scales was supported lJy a significant correlation between the two.Both measures were also significantly related to scores on the Mississippi Scale for Combat-Related PTSD (M-PTSD).A correlation between combat andM-PTSD scores replicatedprevious studies.Subjects scored significantly higher than normals on.the Childhood Dissociative Predictors Scale.Findings indicate a strong dissociative component in PTSD.Results offer initial empirical supportfor a dispositionalstressor model ofPTSD analogous to that proposed for MPD.
