Objectives: This study aimed to establish a Chinese version of the Child Perceptions Questionnaire for children aged 8-10 years (CPQ8-10) and evaluate its reliability and validity for a comprehensive and reliable assessment of oral health-related quality of life in children.
Methods: The Chinese CPQ8-10 was formed through translation, reverse translation, and cross-cultural adaption according to international standard procedures. It was used to evaluate the children's oral health-related quality of life to assess the reliability and validity of the scale.
Results: A total of 446 children received the survey, and 405 valid questionnaires were obtained. Cronbach's a for the full scale was 0.87, and the intraclass correlation coefficient for the total scale was 0.88. The CPQ8-10 score was significantly correlated with the score of two global questions (P<0.01). The dental caries group had the highest score of the full scale, followed by the malocclusion group; the healthy group had the lowest score (P<0.01).
Conclusions: The Chinese version of CPQ8-10 demonstrates great reliability and validity and provides a theoretical basis for its application in Chinese children aged 8-10 years.
目的: 旨在建立中文版8~10岁儿童感知问卷（CPQ8~10），评价其信度和效度，为将来全面、可靠地评估8~10岁儿童口腔健康相关生存质量打下基础。方法: 遵循国际标准程序对英文版CPQ8~10量表进行翻译、回译和质量评价，形成中文版8~10岁儿童感知问卷，利用该量表对8~10岁的儿童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: 累计调查446名适龄儿童，获得有效问卷405份。中文版CPQ8~10的Cronbach’s α系数为0.87，组内相关系数为0.88，量表得分和儿童口腔健康自我评估问题得分密切相关（P<0.01）。全量表的得分为龋病组最高，错牙合畸形组次之，健康组最低（P<0.01）。结论: 本研究证明了中文版CPQ8~10具有良好的信度和效度，为其在中国8~10岁儿童中的应用提供了理论依据。.
