Turkish validity and reliability of Eustachian tube dysfunction questionnaire-7

Abstract Introduction During clinical evaluations, in order to interpret patients' complaints caused by Eustachian tube dysfunction and to monitor the success of the treatment, standardized and disease-related scales are necessary. Objective The aim of this study was to investigate the validity and reliability of the Turkish version of Eustachian tube dysfunction questionnaire-7. Methods Forty patients diagnosed with Eustachian tube dysfunction and 40 healthy individuals were enrolled for the study. After language validation of the Eustachian tube dysfunction questionnaire-7 for Turkish, a scale was completed by the both Eustachian tube dysfunction and control groups. Two weeks after the first evaluation, 15 of the cases filled out the scale again without any treatment intervention. Known-groups method was used in validity analysis. Floor-ceiling effect, test-retest method, item-total score correlation and internal consistency analysis were used in reliability analyses. Results Cronbach's alpha coefficient was 0.714 for the entire questionnaire. The test-retest reliability coefficient for the total scale was determined as 0.792, indicating correlation between the two questionnaires completed by the same patient over time. In the Eustachian tube dysfunction group, total and each item scores were found significantly higher than the control group (p < 0.001). Conclusion The Turkish version of Eustachian tube dysfunction questionnaire-7 was found to be highly valid and reliable. This scale is recommended to use for screening of Eustachian tube dysfunction and evaluating treatment outcome.

摘要：在临床评估过程中，为准确解读咽鼓管功能障碍（Eustachian Tube Dysfunction, ETD）引发的患者主诉并监测治疗效果，标准化且贴合疾病特征的相关量表必不可少。研究目的：本研究旨在探讨土耳其语版咽鼓管功能障碍问卷7（Eustachian Tube Dysfunction Questionnaire-7, ETDQ-7）的效度与信度。方法：本研究共纳入40例确诊为咽鼓管功能障碍的患者与40名健康个体。在完成咽鼓管功能障碍问卷7的土耳其语语言验证后，病例组与对照组均完成该量表填写。首次评估两周后，其中15例受试者在未接受任何治疗干预的前提下再次填写了该量表。效度分析采用已知组别法；信度分析则涵盖地板/天花板效应分析、重测法、条目-总分相关性分析及内部一致性分析。结果：整个问卷的克朗巴哈α系数（Cronbach's alpha coefficient）为0.714。总量表的重测信度系数为0.792，提示同一患者两次填写的问卷结果随时间呈现显著相关性。咽鼓管功能障碍组的总分及各条目得分均显著高于对照组（p < 0.001）。结论：土耳其语版咽鼓管功能障碍问卷7具备良好的效度与信度，推荐将其用于咽鼓管功能障碍的筛查及治疗效果评估。
