Abstract

Objectives: The Chronic Otitis Media Questionnaire-12 (COMQ-12) assesses patient-reported health-related quality of life. A multinational collaborative project was performed to translate and appraise the psychometric properties of the COMQ-12 across Europe, Asia, and South America.

Methods: Eight otology units from seven countries (China, Colombia, France, Italy, Japan, Korea, Turkey) created native versions of the COMQ-12 by the process of translation and back-translation. Questionnaire reliability was assessed on the basis of internal consistency by calculating Cronbach's coefficient alpha. Exploratory factor analysis was performed to identify underlying correlations between individual questionnaire items.

Results: This study included 478 participants from 8 countries. Calculated values for Cronbach's coefficient alpha were between 0.71 and 0.90. Exploratory factor analysis allowed the identification of three dominant factors, the primary factor (related to hearing problems) explaining 42% of the total variance, the secondary factor (related to daily activities) explaining 30% of the variance, and the third factor (related to acute disease activity) explaining 28% of the variance.

Conclusions: This is a large study of patients with chronic otitis media, from centers from within many different countries spanning Europe, Asia, and South America. This study supports the use of the COMQ-12 within the individual countries where it was tested.
