ABSTRACT

Oral mucosal diseases, such as acute and chronic oral lesions, may have an impact on an individual's quality of life. OHRQoL is a tool that can be used to determine whether an individual's quality of life is impaired by oral diseases. One of the OHRQoLs that has been utilized often for chronic oral mucosal diseases is the COMDQ-26. This study aims to analyze the Indonesian COMDQ-26 indices’ validity and reliability in patients with both acute and chronic oral lesions. An analytic observational study using a cross-sectional design was conducted on subject with oral lesions. Indonesian version of COMDQ-26 was constructed and tested on 30 subjects. Rasch model was used to analyze data. Population was found predominantly female (76.6%) with age >30-40 years old (33.33%). Acute oral lesions were found to have a COMDQ-26 score of 31 (24–53), but chronic oral lesions was shown to have a score of 32 (13–73). The Cronbach alpha for the Indonesian version of the COMDQ-26 was 0.83 and the item reliability was 0.92 with separation of 3.35. Unidimensionality score was 4.3. The Indonesian version of the COMDQ-26 shown strong construct validity, despite the fact that it is still unable to distinguish between the impact of quality of life based on the type of oral lesion. The use of the Indonesian version of the COMDQ-26 has to be reconfirmed by additional investigation.
