Abstract:
BACKGROUND AND OBJECTIVES: The Chronic Ear Survey (CES) has been known to be a valid, disease-specific measure for the evaluation of health status and treatment effectiveness for chronic otitis media patients. As part of this study, we developed a Korean version by adapting from this CES, determined its reliability and validity. MATERIALS AND METHOD: The development of the Korean version of CES (K-CES) included the processes of standard independent translation and cross-cultural adaptation to check for cultural inconsistency. The finalized K-CES was administered to 166 patients visiting 10 referral hospitals in a prospective manner. K-CES was validated by using the Cronbach's alpha coefficient, confirmatory factor analysis and test-retest analysis for reliability and validity. The 36-Item Short Form Health Survey Instrument (SF-36) was assessed and the result was used to evaluate the criterion validity. RESULTS: The K-CES demonstrated good test-retest reliability and internal consistency (Cron-bach's alpha=0.850). Scale-item correlation coefficient was even higher than 1.0, which shows a very high reliability of K-CES. The validity of K-CES, checked by confirmatory factor analysis, also showed good construct validity. There was high correlation between SF-36 and the scores of K-CES, which indicates high criterion validity. CONCLUSION: We concluded that K-CES is a valid tool for clinical use and research studies in Korean patients with chronic otitis media.
