Inclusion of the dissociative subtype of posttraumatic stress disorder (d-PTSD) in DSM-5 has opened enormous research opportunity for probing underlying mechanism and its clinical implications. However, there is no consensus about how the diagnoses of d-PTSD should be made because previous studies exclusively used latent profile or class analyses and unavailability of rating scales optimized for diagnostic criteria. This study investigated prevalence and covariates of d-PTSD in a cohort of outpatients with DSM-IV PTSD in a specialized trauma clinic in South Korea. Data from 243 patients with civilian PTSD were examined for this study including demographics, clinical variables, the Clinical Global Index, and the Clinician-administered PTDS scale (CAPS). We defined d-PTSD as presence of either depersonalization or derealization in additional items of the CAPS. Accordingly, about one third (n = 79, 32.5%) were designated as having d-PTSD. Compared to none d-PTSD patients, they were younger and had more severe PTSD symptoms, frequent interpersonal trauma, and higher number of comorbid disorders. When these variables and their interactions were entered in logistic regression analysis, severe PTSD symptoms and younger age with two more comorbid conditions remained for the final model. This study demonstrated high prevalence of d-PTSD in real-world clinical population. Associated features of d-PTSD were similar to findings in the literature and cross-cultural universality was supported from our findings. In fact, actual rate of d-PTSD may be higher using clinical rating than estimation from latent profile or class analyses
