Abstract
BACKGROUND: Eustachian tube dysfunction (ETD) is a common otolaryngological disorder. The seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) was used for the assessment of symptoms related to ETD and treatment outcome. Currently, there is no traditional Chinese version of the ETDQ-7 to diagnose ETD in Taiwan. We aim to verify the reliability and validity of the traditional Chinese version of the ETDQ-7 in a clinical setting. METHODS: The traditional Chinese version of the ETDQ-7 was completed by 60 adult subjects composed of 30 healthy controls and 30 subjects diagnosed with ETD. The internal consistency was evaluated using the Cronbach's α coefficient. The discriminant validity was calculated by receiver operating characteristic (ROC) curve as an accuracy measure. RESULTS: The overall Cronbach's α coefficient of the traditional Chinese version ETDQ-7 was 0.717. The mean ETDQ-7 total score was 26.97 in the ETD group and 9.27 in the control group. The area under the ROC curve (AUC) was 99.8%, and the sensitivity and specificity of the traditional Chinese ETDQ-7 was 100% and 99.9%, respectively. CONCLUSION: The traditional Chinese version of the ETDQ-7 is a valid and reliable, disease-specific rating scale that can be used to quantitatively evaluate the severity of subjective symptoms of ETD in adult patients.
