Validity and Test-Retest Reliability of the Dutch Version of the Chronic Otitis Media Questionnaire 12 (COMQ-12).

Objective: To test the validity and test-retest reliability of the Dutch translation of the Chronic Otitis Media Questionnaire 12 (COMQ-12).

Materials And Methods: Thirty-five healthy individuals with no history of chronic otitis media (COM) received the questionnaire as well as a group of 35 patients with complaints of COM. The healthy participants had to complete the questionnaire twice (control group 1 and control group 2) to estimate the test-retest reliability, and their scores were compared with those of the patients (group 3) to test the validity.
