Cross-cultural adaptation and determining validity and reliability of the Persian revised Buffalo model questionnaire

Background and Aim: The majority of auditory processing guidelines use questionnaires or che-cklists as screening tools. The Buffalo Model Questionnaire (BMQ) is a well-known and sen-sitive questionnaire to be used along with the Buffalo Model diagnostic test battery. The revi-sion for the Buffalo Model Questionnaire-Revised (BMQ-R) implemented to improve the readability of the BMQ, reducing the completion time and increasing the ease of scoring for the audiologist. The purpose of this study was to develop and investigate the psychometric properties of the Persian version of BMQ-R (P-BMQ-R). Methods: After cross-cultural adaptation of the questionnaire, the validity and reliability were determined, also the norms for the children in age ranges between 7 and 12 were generated. Results: Findings of this study revealed strong content and face validity of the questionnaire. Scores of the test and retest were correlated (r 0.9) strongly and positively based on Spear-man correlation coefficient. Conclusion: The Persian version of BMQ-R (P-BMQ-R) is a valid and reliable tool and is suitable to use in everyday practice.
