牙本质敏感影响程度量表简化版的验证性因素分析

目的 应用验证性因素分析考评牙本质敏感影响程度量表简化版（DHEQ-15）的三维维度结构。方法 采用DHEQ-15中文版对210名18~70岁牙本质敏感患者进行生活质量调查。应用验证性因素分析测试构建的量表三维模型的适切性。结果 回收有效量表210份。量表条目中“因牙齿敏感比其他人吃饭时间更长”得分最高。修正模型的主要指标中,卡方/自由度=2.213,拟合指数=0.905,调整拟合指=0.872,标准拟合指数=0.845,增量拟合指数=0.962,塔克-刘易斯指数=0.969,比较拟合指数=0.977,误差平方根近似值=0.068,均达到模型拟合标准。结论 含有三因子的结构模型与数据拟合度较好,证实DHEQ-15具有良好的结构效度,可在国内牙本质敏感患者中进一步推广应用。

Confirmatory factor analysis of the shortened dentine hypersensitivity experience questionnaire

Objective This review aims to identify the dimensional structure of the shortened dentine hypersensitivity experience questionnaire (DHEQ-15) using confirmatory factor analysis (CFA). Methods The Chinese language version of DHEQ-15 was applied to 210 patients with dentine hypersensitivity aged 18-70 years old. The three-dimensional construct was confirmed by CFA.Results All the questionnaires were fully completed. The item “Because of the sensations, I take longer to finish a meal than others” was the most frequently reported by the parents. The modified three-factor model is suitable for the data. The chi-square fit statistics/degree of freedom was 2.213, the goodness-of-fit index was 0.905, the adjusted goodness-of-fit index was 0.872, the normed fit index was 0.845, the incremental fit index was 0.962, the Tucker-Lewis index was 0.969, the comparative fit index was 0.977, and the root mean square error of approximation was 0.068. Conclusion Our findings generally support the three-dimensional construct of the DHEQ-15. Thus, DHEQ-15 can be used as a valid instrument in patients with dentine hypersensitivity in China.
