儿童口腔健康影响程度量表的研制

目的评价儿童口腔健康影响程度量表（CPQ11- 14）中文版的信度和效度，探讨其在中国儿童中应用的可行性。方法对CPQ11- 14进行翻译、回译、文化调适和改造，建立儿童口腔健康影响程度量表中文版。使用该量表和口腔健康自我评价表对南宁市218名11～14岁中、小学生进行口腔健康检查和口腔健康相关生存质量调查，考评量表的信度和效度。结果口腔健康影响程度量表的重测信度系数为0.82（P<0.001），内部一致性Cronbach′s α系数为0.79。通过因子分析提取的5个因子显示，口腔健康影响程度量表存在预想的连带关系和逻辑关系。量表得分与自我评价的口腔健康状态、自我感觉口腔健康对生活质量的影响间有明显相关性，其相关系数分别为- 0.33和0.50（P<0.000 5）。量表得分与龋失补牙指数呈明显正相关（P<0.001），与中学组错畸形情况（美牙指数）也呈正相关（P<0.05）。结论本量表具有良好的信度和效度，为在中国进一步推广应用提供了理论依据。

Validation of a Chinese version of the child perception questionnaire

OBJECTIVE: To translate the original English version of the child perception questionnaire (CPQ(11-14)) into Chinese version and to test the psychometric properties of the Chinese version in order to use among the Chinese children. METHODS: The original English version of CPQ(11-14) was translated into Chinese, and pre-tested and cross-cultural adapted. Subsequently, the Chinese version with a general questionnaire was administered to 218 children aged from 11 to 14, clinical data on caries status and malocclusion were collected through oral health examination. RESULTS: Test-retest reliability was substantial (r=0.82, P<0.001). Cronbach's alpha of the translated scale was 0.79. The 16 items were divided into five domains by factor analysis. There was certain logical relation between the items in the same domains. There was highly significant association between perceived oral health status, perceived impact to quality of life by oral health and CPQ(11-14) score (P<0.0005). Significant relationships were identified between caries status and CPQ(11-14) scores (P<0.001), and between malocclusion and CPQ(11-14) scores in middle-school-group (P<0.05). CONCLUSION: The translated Chinese version of CPQ(11-14) demonstrated good reliability and validity. Its good psychometric properties provide the theoretical evidence for further use in Chinese population. It is available for use by researchers in oral health related quality of life studies in Chinese children.
