Translation and validation of parental perspective questionnaire for children with cochlear implant in persian language.

Parental views about the outcomes of implantation on the child's quality of life are valuable sources of information for implantation specialists. The aim at this study was to validate the "Parental Perspectives" questionnaire in Persian language. The original questionnaire was translated from English to Persian language; the final Persian version of questionnaire was prepared and evaluated for validity and reliability. The internal consistency of the questionnaire and test-retest reliability were respectively evaluated by Cronbach's alpha and ICC index. Factor analysis was used to determine the construct validity. The participants of this study were 370 parents of CI children. Sampling adequacy for executing of factor analysis was confirmed by the results of Kaiser-Meyer-Olkin (=0.84) and Bartlett test ( < .05). 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 ( = 0.76). Reliability coefficient was calculated as 0.93. The Persian version of the questionnaire has good validity and reliability and can be used to examine the perspectives of the parents about CI.
