Abstract
Introduction: Chronic eustachian tube dysfunction (ETD) is the pathophysiologic basis of many middle ear diseases. Unfortunately there is a lack of diagnostic tool for this condition. The ETDQ-7 is a 7-item questionnaire which has been consistently studied and proven reliable and valid for the evaluation of eustachian tube dysfunction. We aim to translate ETDQ-7 into Bahasa Malaysia (BM) version and determine its validity. Methods: This cross-sectional study was carried out in the Otorhinolaryngology , Head and Neck Surgery Department of University Sains Malaysia from March 2020 until January 2021. Translated Bahasa Malaysia version of ETDQ-7 was produced following rigorous forward and backward translation. The BM-ETDQ-7 undergo Face Validity (FV) testing in 10 patients. Following satisfactory FV index, 126 participants, including 60 participants with ETD and 66 healthy control participants were recruited to complete the BM-ETDQ-7. Participants grouped in ETD were those who have positive ETD complains and abnormal tympanogram. A subset of participants from both group repeated the BM ETDQ-7 in time frame of 2 weeks Results: Internal consistency testing of translated ETDQ-7 yielded a Cronbach α value of 0.878. Test- retest reliability showed good ICC coefficient (>0.9), and good correlation (r > 0.8). The BM-ETDQ-7 showed good discrimination between both groups with a significantly higher individual and total mean score. A score of 17.5 were found to be the optimal value to differentiate both groups Conclusion: The present study showed good reliability and validity of BM-ETDQ-7 when applied to both ETD and healthy participants. We recommend the use of BM- ETDQ-7 in clinical practice among Bahasa Malaysia- speaking population
