摘要
目的对5条目口腔健康影响程度量表(OHIP-5)进行信度和效度评价。方法按照国际生活质量量表准则,形成OHIP-5中文版,该量表包括5个条目。将OHIP-5中文版应用于就诊的患者,最终对调查结果进行统计学分析。采用内部一致性信度、重测信度对量表的信度进行考评;采用结构效度和收敛效度对量表的效度进行评价。结果共回收有效问卷556份。量表总的克朗巴赫α系数为0.868,重测信度系数为0.831。经过验证性因子分析,修正模型的主要指标中,卡方/自由度=2.419,拟合指数=0.995,调整拟合指数=0.960,标准拟合指数=0.996,增量拟合指数=0.997,塔克-刘易斯指数=0.985,比较拟合指数=0.997,误差平方根近似值=0.070,均达到模型拟合标准。量表总分的Spearman’s等级相关系数为0.674。结论OHIP-5中文版通过严格的性能测试,信度和效度良好,可在临床研究及流行病学调查中进一步推广应用。
Objective To evaluate the reliability and validity of the Chinese version of the 5-item oral health impact profile(OHIP-5).Methods According to the international guidelines,the Chinese version of the OHIP-5 was produced.It was applied to patients who visit our clinic.The reliability of the scale was evaluated by internal consistency reliability and testretest reliability.In addition,the validity of the scale was evaluated by construct validity and convergent validity.Results A total of 556 patients were enrolled in the study.The Cronbach’s alpha and the intraclass correlation coefficient values(ICC)of the Chinese version of the OHIP-5 were 0.868,0.831,respectively.The results of the confirmatory factor analysis(CFA)showed that the one-factor model provided an acceptable fit to the data.The fit indices were:the chi-square fit statistics/degree of freedom(χ^2/df)=2.419,the goodness-of-fit index(GFI)=0.995,the adjusted goodness of fit index(AGFI)=0.960,the normed fit index(NFI)=0.996,the incremental fit index(IFI)=0.997,the Tucker-Lewis index(TLI)=0.985,the comparative fit index(CFI)=0.997,and the root mean square error of approximation(RMSEA)=0.070.For the convergent validity of the scale,the Spearman’s rank correlation coefficient was 0.674.Conclusion The Chinese version of OHIP-5 had a good reliability and validity by rigorous psychometric properties.Overall,it can be further promoted in clinical research and epidemiological investigations.
