Background:The 11 th version of the International Classification of Diseases (ICD-11) revised the diagnosis of Posttraumatic Stress Disorder (PTSD) and introduced Complex PTSD as a sibling disorder to PTSD. As the Danish Health Authorities will implement the ICD-11 in 2022, it is more relevant than ever to introduce a measure that enables the identification of ICD-11 PTSD and CPTSD. Objective: The primary aim of the present study was to test the construct validity of the ICD-11 conceptualization of PTSD and DSO in five clinical samples using translated versions of the International Trauma Questionnaire (ITQ). Method: Data from existing studies of adult survivors of sexual abuse (n = 385), women in shelters (n = 147), psychiatric outpatients endorsing an ICD-10 diagnosis of PTSD (n = 111), a heterogenous sample of psychiatric outpatients (n = 178) and refugees and torture survivors (n = 385) was used for the current study. Confirmatory factor analyses were conducted to test the internal structure of the ITQ, and regression models were conducted to test the convergent and discriminant validity of the factor solutions for each sample. Results: Findings supported the ICD-11 formulation of PTSD and disorders in selforganization (DSO) as a representation of the latent structure of the ITQ across five Danish clinical samples. Uniquely for women in shelters, however, the model displayed an unacceptable fit. A revised operationalization of re-experiencing proved a better fit when 'recurrent nightmares' was exchanged with symptoms of intense emotional reactions to reminders of the trauma for women in shelter as well as ICD-10 PTSD psychiatric outpatients. Conclusion:This study supports the use of a Danish translated version of the ITQ to assess symptoms of ICD-11 PTSD and DSO for the introduction of ICD-11 in 2022. Future research is needed to further explore the operationalization of re-experiencing across different trauma exposed populations. Validación del tept y DSO de la CIE-11 usando el cuestionario internacional de trauma en cinco muestras clínicas reclutadas en DinamarcaAntecedentes: La décimo primera versión de la Clasificación Internacional de Enfermedades (CIE-11) revisó el diagnóstico de Trastorno de Estrés Postraumático (CIE-11) e introdujo el TEPT complejo como un diagnóstico hermano del TEPT. Como las autoridades de salud danesas implementarán la CIE-11 en el 2022, es más relevante que nunca introducir una medición que permita la identificación del TEPT y el TEPT complejo de acuerdo a la CIE-11. Objetivo: El principal objetivo del presente estudio fue probar la validez del constructo diagnóstico de la conceptualización del TEPT y de las Alteraciones en la Auto-Organización (DSO por sus siglas en inglés) en cinco muestras clínicas usando versiones traducidas del Cuestionario Internacional de Trauma (ITQ por sus siglas en inglés). Método: Se usaron para el presente estudio, datos de estudios ya existentes de sobrevivientes adultos de abuso sexual (n = 147), pacientes psiquiátricos ambulatorios con diagnóstico ...
