COMQ-12

<b>Purpose:</b> Chronic otitis media (COM) can seriously impact quality of life (QOL). Disease-specific questionnaires are essential for an accurate assessment of this impact. To date, there is no questionnaire available for French-speaking patients with COM. This study aims to adapt and validate the French version of the COMQ-12 questionnaire. <b>Methods: </b>This is a controlled, prospective study, conducted between May 2020 and December 2021. Translation was performed using a forward-backward technique, and statistical validation was performed with a COM patients and a controls adult cohorts. <b>Results: </b>100 patients (mean age 48±16), and 50 controls (mean age 41±16; p=0.02) completed the test. Internal consistency, assessed by Cronbach’s alpha, was 0.870 for the cases group. The mean COMQ-12 total score was 23.92±11.3 for cases versus 3.70±6.15 for controls (p&lt;0.0001). ROC-curve analysis showed 96% sensitivity and 84% specificity for diagnosis of COM with a overall score &gt;6. Individual items all had high discriminatory performances. 3 items (Q1, Q2, Q9) had weaker correlation with the other items and the global score, but did not have a negative impact on internal consistency. <b>Conclusion: </b>The French version of the COMQ-12 is a short and easy-to-use test, with robust statistical properties, for assessing QOL in patients with COM.<b></b> <b> </b>
