Three factors were extracted from exploratory factor analysis. Confirmatory factor analysis confirmed the accuracy of the three-dimensional structures. Principal component analysis revealed the structural validity of three factors. Correlation between questionnaire items was good (r = 0.76). Reliability coefficient was calculated as 0.93.Conclusions: The Persian version of the questionnaire has good validity and reliability and can be used to examine the perspectives of the parents about CI.
