儿童口腔健康相关生存质量量表信度与效度的验证研究

摘要

目的 通过对8～15岁儿童口腔健康相关生存质量量表(COHIP)中文版信度与效度的验证研究,探讨其在中国适龄儿童中应用的可行性.方法 按照国际生存质量评价项目的标准程序,对英文原版COHIP系列问卷中的儿童问卷、父母问卷分别进行翻译、回译、文化调适和改造,建立中文版COHIP,形成适应儿童口腔健康和治疗需求的自我评估问卷、内容效度指数(CvI)合格的评估量表.使用该系列量表对8～15岁的儿童及其家长进行儿童口腔健康相关生存质量调查,考评量表的信度和效度.结果 1 189对儿童及家长接受问卷调查,收回有效问卷1 143份,量表完成率为96.1％.COHIP儿童表内部一致性Cronbach's α[系数为0.903,条目-量表相关系数为0.134～0.611,Guttman分半信度系数为0.798,组内相关系数(ICC)为0.926.COHIP家长表内部一致性Cronbach'sα系数为0.796,条目-量表相关系数为0.121～0.614,Guttman分半信度系数为0.796,ICC为0.931.因子分析显示中文版量表所包含的条目存在预想的逻辑关系.结论 中文版COHIP具有良好的信度和效度,其良好的心理测量学性质为其在中国适龄儿童中的应用提供了理论依据.%Objective To translate the original English version of child oral health impact profile(COHIP) into Chinese version and test its psychometric properties for use among Chinese eligible children.Methods The original English version of COHIP was translated,back-translated and cross-cultural adapted.Content validity index(CVI) scale and self-assessment for oral health and need for treatment questionnaire were established.Its reliability and validity were assessed in Chinese children aged 8 to15 years and their parents.Results Scales were completed by 1 189 pairs of children and parents,and 1 143 efficient scales were taken back,with the completion 96.1％.Cronbach's α of COHIP(for child) was 0.903,item-total correlation coefficient ranged from 0.134 to 0.611,split-half reliability coefficient was 0.798,interclass correlation coefficient(1CC) was 0.926.Cronbach's α ofCOHIP(for caregiver) was 0.796,item-total correlation coefficient ranged from 0.121 to 0.614,split-half reliability coefficient was 0.796,ICC was 0.931.Factor analysis found that there was certain logical relation among the items in Chinese version of COHIP.Conclusion The translated Chinese version of COHIP demonstrates acceptable reliability and validity.Its satisfying psychometric properties provide the theoretical evidence for further use in Chinese children.
