The pur­pose of this study was translation, cultural adap­tation, determination of reliability and validity of the questionnaire, and assessment of its scores in children with cochlear implant versus normal group. Methods: Questionnaire was translated into Persian and was adapted to meet Iranian cultural context. After confirming face validity, the test was given to a group of normal children (n=54) and a group of cochlear implanted users (n=30). It was tested for reliability after two weeks. Results: Test results showed high Cronbach alpha (0.91) and total inter-class correlation of 0.99 which were higher than respective values in the original version. Significant difference was seen in comparison of scores between chil­dren with cochlear implant and normal children (p=0.026). Conclusion: Persian version of PEACH ques­tionnaire, which is the equivalence of the ori­ginal version, seems to have high validity and reliability and it is a useful tool for evaluating aural/oral performance of hearing impaired chil­dren. https://avr.tums.ac.ir/index.php/avr/article/view/82 https://avr.tums.ac.ir/index.php/avr/article/download/82/48
