| Abstract: | Alternative symptom profiles for posttraumatic stress disorder (PTSD) are presented in the DSM-5 and ICD-11. This study compared DSM-5 PTSD symptom profiles with ICD-11 PTSD symptom profiles among a large group of trauma-exposed individuals from Denmark. Covariates, and rates of co-occurrence with other psychiatric disorders were also investigated. A sample of treatment-seeking adult survivors of childhood sexual abuse (n = 434) were assessed using self-report measures of PTSD and other psychiatric disorders. A significantly larger proportion of individuals met caseness for DSM-5 PTSD (60.0%) compared to ICD-11 PTSD (49.1%). This difference was largely attributable to low endorsement of the ICD-11 re-experiencing criteria. Replacement of the ‘recurrent nightmares’ symptom with the ‘recurrent thoughts/memories’ symptom seemed to balance the proportion of individuals meeting caseness for both taxonomies. Levels of co-occurrence with anxiety and thought disorder were higher for the DSM-5 model of PTSD compared to the ICD-11 model. Current results merit careful consideration in the selection of symptom indicators for the new ICD model of PTSD, particularly with respect to the re-experiencing symptom category. |
