目的: 评价中文版口腔健康素养量表简版(a short-form Health Literacy Dental scale，HeLD-14)在3~6岁学龄前儿童家长中应用的信度和效度。方法: 2021年在北京市延庆区幼儿园通过电子问卷共调查1 479名学龄前儿童家长，了解儿童家长的一般情况、口腔健康素养相关内容。运用SPSS 21.0和Mplus 7.4软件进行统计分析，通过Cronbach’s α系数、验证性因子分析、Pearson相关分析等方法，评价量表的内部一致性信度、结构效度、校标效度和区分效度。结果: 中文版HeLD-14量表的Cronbach’s α系数为0.958，不同维度的Cronbach’s α系数在0.778~0.963。验证性因子分析结果显示，中文版HeLD-14量表各条目因子负荷在0.719~0.977(P < 0.001)，拟合指数近似误差均方根(root-mean-square error of approximation，RMSEA)为0.04，比较拟合指数(comparative fix index，CFI)为0.992，Tucker-Lewis指数(Tucker-Lewis index，TLI)为0.988，模型拟合优度良好。中文版HeLD-14量表总分及关注、理解、支持、经济负担、就医、沟通、运用维度得分均与一般自我效能感正相关，相关系数分别为0.439、0.406、0.370、0.344、0.346、0.367、0.373、0.390(P均 < 0.05)。HeLD-14量表得分排在前27%的高分组3~6岁儿童家长的口腔健康素养平均得分高于得分排在后27%的低分组(69.27±1.06 vs. 41.29±11.09，t=48.13，P < 0.01)。结论: 中文版HeLD-14量表在3~6岁学龄前儿童家长中具有良好的信度和效度，可以作为评估学龄前儿童家长口腔健康素养的工具。

Objective: To assess the reliability, and validity of the Chinese version of a short-form of Health Literacy Dental scale (HeLD-14) in 3-6 years old preschool children's parents. Methods: The study population consisted of those eligible 3-6 years old preschool children's parents in Yanqing District, Beijing, China in 2021. A total of 1 479 preschool children's parents were surveyed by questionnaire to understand the general situation of parents and oral health literacy related content. SPSS 21.0 and Mplus 7.4 were used for statistical analysis. Through Cronbach's α coefficient, confirmatory factor analysis, Pearson correlation calculation, Student's t test and other methods, the internal consistency reliability, structure validity, calibration validity and discrimination validity of the scale were evaluated. Results: The Cronbach's α coefficient of Chinese version HeLD-14 scale was 0.958, and Cronbach's α coefficient of different constructs ranged from 0.778 to 0.963. The confirmatory factor analysis showed that the factor loadings of each item of the Chinese version HeLD-14 scale were between 0.719 and 0.977 (P < 0.001), root-mean-square error of approximation (RMSEA)=0.04, comparative fix index (CFI)=0.992, Tucker-Lewis index (TLI)=0.988, and the model had good goodness of fit. The total score of the Chinese version HeLD-14 scale and the scores of the dimension of concerning, understanding, supporting, financial burden, medical treatment, communication, and application were all positively correlated with general self-efficacy, and the correlation coefficients were 0.439, 0.406, 0.370, 0.344, 0.346, 0.367, 0.373, 0.390, respectively (P all < 0.05). For parents in the high group with the top 27% HeLD-14 score, the average HeLD-14 score was 69.27±1.06, which was higher than the low group with the bottom 27% HeLD-14 score, 41.29±11.09 (t=48.13, P < 0.01). Conclusion: The Chinese version HeLD-14 scale has good reliability and validity in the 3-6 years old preschool children's parents, and can be used as a tool to assess the oral health literacy of parents of preschool children.
