Cultural adaptation and determination of validity and reliability of the Persian version of the parent's evaluation of aural/oral performance of children questionnaire

Parents’ evaluation of aural/oral performance of children (PEACH) questionnaire is used for children within any age group and any amount of hearing loss. 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.
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.
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).
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.
