Background: The World Health Organization recently released the 11th revision of the International Classification of Diseases with the inclusion of Complex Posttraumatic Stress Disorder (CPTSD). ICD-11 construed CPTSD as a disorder comprising of posttraumatic stress disorder (PTSD) and disturbance of self-organization (DSO) domains. In order to have a CPTSD diagnosis, PTSD subdomains (reexperiencing, avoidance, and threat) and DSO subdomains (affective dysregulation, negative self-concept, and interpersonal relationship difficulties) need to be satisfied. Despite the emerging research examining the symptom structure of CPTSD, to date, none so far have reached consensus on what best represents CPTSD.
Aims: The purpose of this study was to prepare a Persian version of the International Trauma Questionnaire (ITQ) and to examine its psychometric properties among Iranian women.
Methods: 259 people were selected using the convenience sampling method and completed the Persian version of International Trauma Questionnaire. Data were analyzed using Cronbach's alpha indices, composite reliability and confirmatory factor analysis.
Results: Cronbach's alpha coefficient for PTSD was 0.83 and for DSO was 0.81 and the combined reliability of the test was more than 0.8. The results of confirmatory factor analysis showed that the factor load of the items is more than 0.4 and the scale has good construct validity.
Conclusion: Given the desirable psychometric properties of the Persian version of the International Trauma Questionnaire, its use can be recommended to experts in the field of psychology in research and diagnostic situations.
