Convergent validity was tested by examining the association of HKOHLAT‐P scores with those derived from the Test of Functional Health Literacy in Dentistry (TOFHLiD) and Hong Kong Rapid Estimate of Adult Literacy in Dentistry (HKREALD‐30). The predictive validity of HKOHLAT‐P was determined by testing the association between HKOHLAT‐P and children's caries experience (dmft) and the Chinese Early Childhood Oral Health Impact Scale (ECOHIS). The test‐retest reliability and internal consistency of HKOHLAT‐P were also evaluated.</p> </sec> <sec id="ipd12021-sec-0004" sec-type="section"> <title>Results</title> <p>HKOHLAT‐P was positively correlated with TOFHLiD and HKREALD‐30 (<italic>P</italic> < 0.01), and was negatively correlated with children's dmft and ECOHIS. In the regression model, HKOHLAT‐P was associated with TOFHLiD, HKEALD‐30, children's dmft, and ECOHIS (<italic>P</italic> < 0.05) after controlling for participants' demographic characteristics. The intra‐class correlation coefficient of HKOHLAT‐P was 0.63 and the Cronbach's α was 0.71.</p> </sec> <sec id="ipd12021-sec-0005" sec-type="section"> <title>Conclusion</title> <p>Initial testing of HKOHLAT‐P suggested that it is a valid and reliable instrument.</p> </sec> </abstract>
