Assessing the Persian International Trauma Questionnaire: A psychometric study

Abstract

This study aimed to evaluate the psychometric properties of the Persian version of the International Trauma Questionnaire (ITQ). A confirmatory factor analysis showed that the Persian ITQ maintained the same factor structure as the original version. The internal reliability become great, with a Cronbach's alpha coefficient of 0.89 for the overall scale, and good reliability for the PTSD (alpha = 0.83) and DSO (alpha = 0.88) subscales. Take a look at test-retest reliability over a one-month duration was turned into also excellent for both total scores (ICC = 0.868) and subscale scores (ICC = 0.847 to 0.854). Positive correlations were discovered between ITQ scores and measures of anxiety, depression, and emotion regulation difficulties; however, avoidance did not correlate with impulsivity. The strongest correlation was found between PTSD scores and PTSD severity. Overall, the Persian ITQ demonstrated a sound factorial structure, excellent internal reliability, good test-retest reliability, and showed convergent and discriminant validity, supporting its suitability for Persian-speaking populations.
