title: Dissociation and posttraumatic stress disorder: a latent profile analysis.
abstract: The fifth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, ) contains a dissociative subtype for posttraumatic stress disorder (PTSD) characterized by significant depersonalization and derealization. In this study the PTSD dissociative subtype was examined using latent profile analysis in a sample of 541 trauma-exposed college students. Items from the PTSD Checklist and Multiscale Dissociation Inventory were used as latent class indicators. Results supported a 3-class solution including a well-adjusted class, a PTSD class, and a PTSD/dissociative class characterized by elevated symptoms of PTSD, depersonalization, and derealization. Significant class differences were found on a number of measures of related psychopathology with Cohen's d effect size estimates ranging from 0.04 to 1.86. Diagnostic and treatment implications regarding the dissociative subtype are discussed.
