Abstract:
Background and Objectives:Eustachian tube dysfunction (ETD) is prevalent among patients with ENT disorders, necessitating history-taking, clinical examination, and appropriate investigation for diagnosis. Eustachian Tube Dysfunction Patient Questionnaire (ETDQ-7) is a valuable tool for subjectively assessing symptom severity related to this condition. This study aims to adapt and validate the ETDQ-7 in Greece, ensuring its accuracy and efficacy in outpatient settings.
Subjects and Methods:The ETDQ-7 was translated into Greek following established methodology. Data were collected from 75 Greek patients diagnosed with ETD and 25 control patients without ETD. Participants completed the adapted ETDQ-7 and underwent a clinical examination, with statistical analysis correlating with their ETDQ-7 responses. Statistical analyses were performed to determine the questionnaire’s reliability and validity.
Results:Internal consistency and item analyses were performed to validate the questionnaire. Face and content validity were confirmed, and patients found the questionnaire easy to administer and complete. Test-retest reliability demonstrated similar internal consistency and a strong correlation between individual items and the total score. Discriminative validity revealed a statistically significant difference between the two patient groups, supporting the usefulness of the Greek version of ETDQ-7 in confirming the diagnosis of ETD.
Conclusions:The Greek version of ETDQ-7 proves to be safe and effective for diagnosing ETD in Greek-speaking populations, complementing various investigative methods.
