Aims: The study aimed to evaluate the reliability and validity of the Thai version of Rapid Estimate of Adult Literacy in Dentistry (ThREALD-30). Materials and Methods: The Rapid Estimate of Adult Literacy in Dentistry-30 items (REALD-30) was translated to Thai language and back-translation process to English version of REALD-30 by experts of dentistry and linguistics. This cross-sectional study was conducted with a sample of 1110 patients from the five provinces in Northeast of Thailand. All variables were performed by descriptive statistics. The quality of the development tool of ThREALD-30 was tested internal consistency, reliability, and validity from construct validity and predictive validity correlated with Thai Oral Health Impact Profile 14 items (Thai OHIP-14) and Oral health status, respectively. The statistics were analyzed using STATA version 10. Results: A total of 1110 adult patients with a mean age was 51.11 + 6.63 years old. The reliability of ThREALD-30 was excellent (α = 0.950; intraclass correlation coefficient = 0.970, 95% confidence interval: 0.939–1.000). The construct validity was evaluated to indicate the subscales of ThREALD-30 being trustable by showing the correlation coefficient with their own dimension between 0.345 and 0.773, and predictive validity from Spearman's with Thai OHIP-14 (rrho= −0.688, P < 0.001) and oral health status; decayed, missing, and filled teeth (rrho = −0.283, P < 0.001); Oral Hygiene Index Simplified (rrho = −0.432, P < 0.001); and clinical attachment loss (rrho= −0.470, P < 0.001), supporting the construct and criterion validity. Conclusion: ThREALD-30 is an oral health literacy tool that worked well in the Thai population. It offers a valid and reliable instrument for measuring oral health outcome of the individual in community settings.
