The proposed ICD-11 criteria are more restrictive compared to the ICD-10 criteria. The findings suggest that the two-factor model of ICD-11 PTSD is preferable to the three-factor model. Compared to ICD-11, ICD-10 identified cases with less severe trauma exposure and posttraumatic symptoms and DSM-IV identified cases with less severe trauma exposure. Diagnostic agreement of the ICD-11 PTSD criteria with ICD-10 and DSM-IV was moderate, yet the diagnostic agreement turned to be good when an impairment criterion was imposed on ICD-10. In the studied samples, the three-factor ICD-11 criteria identified 51 (22.4 %) PTSD cases, the two-factor ICD-11 identified 56 (24.6 %) cases and the DSM-IV identified 43 (18.9 %) cases, while the number of cases identified by ICD-10 was larger, being 85 (37.3 %) cases. ResultsĬonfirmatory factor analyses indicated that the proposed ICD-11 PTSD symptoms represented two rather than three factors re-experiencing and avoidance symptoms comprised one factor and hyperarousal symptoms the other factor. PTSD symptom item scores were used to compose diagnoses according to the different classification systems. Semi-structured diagnostic interviews were performed to assess psychiatric diagnoses and PTSD symptom scores ( N = 228, mean age 17.6 years). Two samples of adolescents and young adults were followed after exposure to similar mass shooting incidents in their schools. Possible differences in clinical characteristics of the PTSD cases identified by ICD-11, ICD-10 and DSM-IV are explored. The aim of this study was to evaluate the ICD-11 PTSD factor structure in samples of young people, and to compare PTSD prevalence rates and diagnostic agreement between the different diagnostic systems.

The proposed posttraumatic stress disorder (PTSD) criteria for the International Classification of Diseases (ICD) 11th revision are simpler than the criteria in ICD-10, DSM-IV or DSM-5.
