目的:评价学龄前儿童口腔健康影响程度量表(The Early Childhood Oral Health Impact Scale,ECOHIS)中文版的信度和效度。方法:对ECOHIS进行初译、回译、质量评价、文化调适和预评估,形成ECOHIS中文版,进而将其应用于成都市两部分人群,一部分为随机选择的成都市2所幼儿园的200名学龄前儿童;另一部分是在四川大学华西口腔医院儿童牙病科就诊的100例3～5岁患儿。通过这些儿童的监护人完成问卷调查,最终对调查结果进行统计学分析,考评量表的信度和效度。结果:①共回收有效问卷292份,有效问卷的回收率为97.3%;②信度—量表总的克朗巴赫α系数为0.899,Guttman分半信度系数为0.799,表格之间相关性r=0.666;③结构效度—经过验证性因子分析,提取3个因子,累积贡献率达63.87%,显示量表存在预想的连带关系和逻辑关系;判别效度—所有条目均能区分幼儿园普通儿童和患儿的生命质量差异(P值均<0.01)。结论:ECOHIS中文版通过严格的性能测试,具有良好的信度和效度,可在我国学龄前儿童中推广应用。
Objectives: To evaluate the reliability and validity of the Chinese version of The Early Childhood Oral Health Impact Scale (ECOHIS). Methods: ECOHIS was first translated, back translated, evaluated in quality, adapted to culture and pre-evaluated to form ECOHIS Chinese version, which was applied to two groups in Chengdu. Some of them were 200 randomly selected two kindergartens in Chengdu Former children; the other part is in Sichuan University Huaxi Stomatological Hospital pediatric dentistry of 100 cases of 3 to 5-year-old children. Through these children’s guardians to complete the questionnaire, the final statistical analysis of the survey results, evaluation scale reliability and validity. Results: (1) A total of 292 valid questionnaires were collected, the effective rate of the questionnaires was 97.3%; (2) the overall Cronbach’s alpha coefficient was 0.899, Guttman’s semi-reliability coefficient was 0.799, the correlation between the tables was r = 0.666; ③ Structural validity - After confirmatory factor analysis, three factors were extracted, the cumulative contribution rate reached 63.87%, indicating that the scale has the expected relationship and the logic; Discriminant validity - all entries can distinguish between ordinary children in kindergarten and The difference in children’s quality of life (P <0.01). Conclusion: The Chinese version of ECOHIS passed strict performance tests and has good reliability and validity. It can be widely applied in preschool children in China.
