Comparing diagnostic criteria for posttraumatic stress disorder in a diverse sample of trauma ‐exposed youth

AbstractDivergent conceptualization of posttraumatic stress disorder (PTSD) within theDiagnostic and Statistical Manual of Mental Disorders (5th ed.;DSM-5) andInternational Statistical Classification of Diseases and Related Health Problems (11th ed..;ICD-11) significantly confounds both research and practice. Using a diverse sample of trauma-exposed youth (N = 1,542, age range: 8 –20 years), we compared these two diagnostic approaches along with an expanded version of theICD-11 PTSD criteria that included three additional reexperiencing symptoms (ICD-11+). Within the sample, PTSD was more prevalent using theDSM-5 criteria (25.7%) compared to theICD-11 criteria (16.0%), with moderate agreement between these diagnostic systems, κ = .57. The inclusion of additional reexperiencing symptoms (i.e.,ICD-11+) reduced this discrepancy in prevalence (24.7%) and increased concordance withDSM-5 criteria, κ = .73. All three PTSD classification systems exhibited similar comorbidity rates with major depressive episode (MDE) or generalized anxiety disorder (GAD; 78.0%–83.6%). Most youths who met theDSM-5 PTSD criteria also met the criteria forICD-11 PTSD, MDE, or GAD (88.4%), and this proportion increased when applying theICD-11+ criteria (95.5%). Symptom-level analyses identified reexperiencing/intrusions and negative alterations in cognition and mood symptoms as primary sources of discrepancy between theDSM-5 andICD-11 PTSD diagnostic systems. Overall, these results challenge assert...
