Cross-cultural validity and psychometric properties of the International Trauma Questionnaire in a clinical refugee sample.

ABSTRACT: Background: The ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD diagnoses have been examined in several studies using the International Trauma Questionnaire (ITQ). The cross-cultural validity of the ITQ has not previously been studied using item responses theory methods focused on the issue of equal item functioning and thus comparability of scores across language groups.Objective: To investigate the cross-cultural validity of the ITQ scales considering specifically local independence of items and differential item functioning (DIF) in a cross-cultural sample of refugees.Method: Data from 490 treatment-seeking refugees were included, covering Danish, Arabic, and Bosnian languages and different levels of interpreter-assisted administration.
