Dissociative symptoms in a substance abuse population.

Abstract

This study was intended to examine the extent of dissociative experiences that exist within a substance abuse population and to determine how demographic and clinical variables affect these experiences. A total of 265 male veterans being treated on an inpatient substance abuse unit completed a standard test battery that included the MMPI-2, the Shipley-Hartford Institute of Living Scale, and the Dissociative Experiences Scale. Additional demographic and clinical information was obtained from the patients' medical records. Over 41% of the cohort had scores on the Dissociative Experiences Scale that suggested the need for further evaluation of a dissociative disorder. A stepwise multiple regression analysis revealed that level of psychological discomfort, IQ, and race accounted for more than 24% of the variance in Dissociative Experiences Scale scores. Substance abuse populations may need to be routinely screened for dissociative symptoms just as they are for depression and anxiety.
