目的:建立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,并分析其信度、效度。方法:按量表翻译程序将问卷翻译成中文,并在武汉市幼儿园中随机选择180名3～5岁的儿童,要求其完成ECOHIS问卷。随机选择18名患者两周后重填问卷。结果:Cronbach’s α系数为0.91,重测信度ICC为0.74。有龋齿和龋病史儿童的ECOHIS分数显著高于没有龋齿的儿童;且ECOHIS分数与DMFT呈显著相关性。结论:中文版ECOHIS问卷具有较好的效度和信度,能用于研究儿童与口腔健康相关的生活质量。
Objective: To establish a Chinese version of the Early Childhood Oral Health Impact Scale (ECOHIS) and analyze its reliability and validity. METHODS: The questionnaire was translated into Chinese according to the scale translation program and 180 children aged 3 ~ 5 were randomly selected from Wuhan Kindergarten to complete the ECOHIS questionnaire. Eighteen patients were randomized to replenish the questionnaire two weeks later. Results: The Cronbach’s alpha coefficient was 0.91 and the retest reliability ICC was 0.74. ECOHIS scores were significantly higher in children with caries and caries than in children without caries; and the ECOHIS score was significantly correlated with DMFT. Conclusion: The Chinese version of the ECOHIS questionnaire has good validity and reliability and can be used to study children’s quality of life related to oral health.
