Cross-cultural adaptation and Italian validation of chronic otitis media outcome test 15 (COMOT-15)

Objective Chronic suppurative otitis media (CSOM) may result in a serious impairment of the quality of life (QoL). The most relevant characteristics of CSOM are well represented in the "Chronic Otitis Media Outcome Test 15" questionnaire (COMOT-15). The aim of the study was to translate and adapt the COMOT-15 questionnaire into Italian. Methods This is a prospective study conducted on 52 Caucasian Italian-speaking patients with CSOM and 52 controls. The linguistic adaptation of the COMOT-15 consisted of the translation of the English version into Italian and reliability assessment of the translation. Psychometric measurements included internal consistency and test-retest reliability. Results Cronbach's α was 0.95. The test-retest reliability showed a strong positive correlation for total score and all subscales. Age and gender had no influence on the scores. The correlation between the COMOT-15 and the pure tone average showed a significant association for the scale "Hearing Function". Conclusions The Italian COMOT-15 questionnaire provides good internal consistency and is suitable for QoL evaluation in Italian-speaking patients suffering from CSOM. In addition, it is able to evaluate the subjective symptoms perceived by patients.
