Abstract

OBJECTIVES

As an important part of health literacy, oral health literacy has been adapted to dental practice and research. The 14-item short version of the Health Literacy in Dentistry (HeLD) scale demonstrated excellent reliability, validity and precision when tested among English-speaking populations. However, an appropriate and reliable assessment of this scale in other language contexts remains lacking. The reliability and validity of the Chinese version of HeLD (HeLD-C) for the Chinese population must therefore be examined.

METHODS

The short version of HeLD was translated into Chinese, and one item was deleted because of its unsuitability for the Chinese healthcare system. The psychometric properties of HeLD-C were evaluated in a sample of 404 Chinese participants aged from 19 to 72 years. The item selection analyses were performed by comparing the difference of each item between the high- and low-score groups. The internal consistency reliability was assessed using the Cronbach's alpha coefficient. Construct validity was assessed using exploratory structural equation modelling. For the criterion validity, correlations between the HeLD-C and the criterion validity scales, including the eHealth Literacy Scale (eHEALS), oral hygiene maintenance habits, and oral health status were tested using Pearson's correlation.

RESULTS

Results of item selection reveal significant differences among all items between the high- and low-score groups (Ps < .001). The internal consistency reliability of HeLD-C was measured using Cronbach's α (0.92), whereas its construct validity was measured using χ [df] (3.30), comparative fit index (0.95), Tucker-Lewis index (0.94), root mean square error of approximation (0.08), and standardized root mean square residual (0.05). The criterion validity analyses show that HeLD-C is correlated with the criterion validity scales, including eHEALS, oral hygiene maintenance habits and oral health status (Ps < .001).

CONCLUSIONS

Chinese version of HeLD is a reliable and valid instrument for measuring the oral health literacy of the Chinese adult population.

摘要

目的

口腔健康素养作为健康素养的一个重要组成部分，已经被应用于口腔医学实践和研究中。在以英语为母语的人群中，14 项口腔健康素养量表（HeLD）短版显示出极好的信度、效度和精准度。然而，在其他语言环境中，对该量表进行适当和可靠的评估仍然缺乏。因此，必须对该量表的中文版本（HeLD-C）在中文人群中的信度和效度进行检验。

方法

将 HeLD 短版翻译成中文，并删除了一个因不适合中国医疗体系而不适用的项目。对 404 名年龄在 19 至 72 岁的中国参与者进行了 HeLD-C 的心理测量学特性评估。通过比较高分组和低分组之间每个项目的差异，进行项目选择分析。采用 Cronbach's alpha 系数评估内部一致性信度。采用探索性结构方程模型评估结构效度。为了检验效标效度，使用 Pearson 相关检验了 HeLD-C 与效标效度量表（包括电子健康素养量表[eHEALS]、口腔卫生维护习惯和口腔健康状况）之间的相关性。

结果

项目选择结果显示，高分组和低分组之间所有项目均存在显著差异（P 值均<.001）。HeLD-C 的内部一致性信度采用 Cronbach's α （0.92）进行测量，而结构效度采用 χ[df]（3.30）、比较拟合指数（0.95）、Tucker-Lewis 指数（0.94）、均方根误差近似值（0.08）和标准化均方根残差（0.05）进行测量。效标效度分析显示，HeLD-C 与效标效度量表（包括 eHEALS、口腔卫生维护习惯和口腔健康状况）相关（P 值均<.001）。
