Abstract

Objective: Recently, the American Psychiatric Association (DSM-5) and the WorldHealth Organization (ICD-11) have both revised their formulation of posttraumaticstress disorder (PTSD). The primary aim of this study was to compare DSM-5 andICD-11 PTSD prevalence and comorbidity rates, as well as the level of disabilityassociated with each diagnosis. Method: This study was based on a representativesample of adult Ukrainian internally displaced persons (IDPs: N = 2,203). PTSDprevalence was assessed using the PTSD Checklist for DSM-5 and the InternationalTrauma Questionnaire (ICD-11). Anxiety and depression were measured using theGeneralized Anxiety Disorder Scale and the Patient Health QuestionnaireDepression.Disability was measured using the WHO Disability AssessmentSchedule 2.0.Results: The prevalence of DSM-5 PTSD (27.4%) was significantly higher than ICD-11 PTSD (21.0%), and PTSD rates for females were significantly higher using bothcriteria. ICD-11 PTSD was associated with significantly higher levels of disability andcomorbidity.Conclusion: The ICD-11 diagnosis of PTSD appears to be particularly well suited toidentifying those with clinically relevant levels of disability.
