Abstract The aim of this study was to test the factorial structure of Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) as outlined in the 11th revision of the International Classification of Diseases (ICD-11) in three African community samples using the International Trauma Questionnaire (ITQ). Four models were tested using confirmatory factor analysis based on a total sample of 2,524 participants, and the two-factor second-order model, representing PTSD and Disturbances in Self-organization (DSO), was the best fitting model. The factors were validated using demographic and trauma-related variables, supporting the use of the ITQ for English-speaking participants in these African countries.
