Objective: Oral health-related quality of life (OHRQoL) questionnaires have been administered to children older than 6 years. Currently, the scale of oral health outcomes for 5-year-old children (SOHO-5) has been used to determine the OHRQoL through self-reports and parental proxy reports of children aged <6 years. This study was conducted to estimate the psychometric reliability and validity after adapting the SOHO-5 to the Indonesian language. Materials and Methods: The cross-cultural adaptation was tested in children aged 5 years old and their parents. The reliability and validity of the questionnaire were measured among 161 kindergarten children in Jakarta, along with a clinical examination for dental caries. Results: Cronbach's alpha coefficients for internal consistency were 0.89 and 0.86 for child's self-reports and parental reports, respectively. The test-retest reliability results were excellent based on repeated administrations in 27 children; the intraclass correlation coefficients were 0.81 and 0.94 for the parental reports and child's self-reports, respectively. No corrected item-Total correlation value was lower than 0.30, allowing all items in the instrument to be included for data analyses. The construct validity of the child's self-reports showed that the Indonesian SOHO-5 total score was significantly associated only with the presence of dental caries (P < 0.001). The construct validity of the parental reports described that the SOHO-5 total score was significantly associated with proxy-rated oral health, the child's perceived dental treatment and satisfaction with the child's oral health (P < 0.001). Conclusions: This study showed the Indonesian version of SOHO-5 is a reliable and valid OHRQoL measure for 5-year-old Indonesian children.
