Abstract
Objective: The need to assess oral health-related quality of life (OHRQoL) has grown increasingly in the healthcare sector over the past few decades. The Dental Impact on Daily Living (DIDL) assessment is a tool created to measure OHRQoL. The aim of this study was to complete a cross-cultural adaptation of the DIDL to yield a valid and reliable Indonesian version for use as an official instrument to assist in further OHRQoL research in Indonesia. Materials and Methods: The original English version of the DIDL was translated and validated. Content validity and face validity were considered. Psychometric testing for test-retest reliability was analyzed among 32 subjects, while internal consistency using Cronbach's alpha and clinical oral health status using the DMF-T index to obtain convergent validity of the questionnaire were checked among 278 subjects. Results: The study subjects showed a good understanding of how to complete the Indonesian language version of the DIDL questionnaire, and conceptual and semantic equivalence (content and face validity) were noted. Further, test-retest reliability was noted (intraclass correlation coefficient range: 0.975-1 and Cronbach's alpha: 0.942), whereas convergent validity suggested a correlation between DMF-T and DIDL questionnaire of -0.502 with significance at alpha of 5% (P = 0.00), which means that decreasing the DMF-T outcome will increase the satisfaction using the DIDL among research subjects. Conclusion: Cross-cultural adaptation of the DIDL yielded a valid and reliable Indonesian version. The DIDL questionnaire is a promising questionnaire that can be applied to measure OHRQoL in Indonesians.
