The evaluation of instruments measuring oral health-related quality of life (OHRQoL) of children has been largely among convenience samples of patients with specific diseases or disorders such as cleft lip/cleft palate or malocclusion.
This study aimed to evaluate the consistency and validity of the recently developed Child Perception Questionnaires (CPQ(8-10) and CPQ(11-14)) and the corresponding Parental Perception Questionnaire (PPQ) in a general child population sample in South Australia.
The study was nested in the Child Oral Health Study. Some 1401 children aged 8 to 13 in 2002/03 were approached. Children were asked to complete the CPQ(8-10) and CPQ(11-14) according to their age while parents completed the PPQ. The questionnaires included global ratings of oral health and overall well-being. Scores for four domains (oral symptoms, functional limitations, emotional well-being and social well-being) were calculated. Data on caries experience (number of decayed, missing and filled tooth surfaces) and occlusal traits (using Dental Aesthetic Index) were collected for each child.
The CPQs and PPQ showed acceptable internal consistency and construct validity against global ratings of oral health and overall well-being. Children who had more caries or less acceptable occlusal traits reported poorer OHRQoL establishing the discriminant validity of the instruments. Parents of the children reported similar child OHRQoL.
These results suggest that the instruments have consistency and validity in measuring OHRQoL of children in a general population.
对测量儿童口腔健康相关生活质量（OHRQoL）的工具的评估，大多是在患有特定疾病或病症（如唇腭裂或错牙合畸形）的患者便利样本中进行的。
本研究旨在评估最近开发的儿童感知问卷（CPQ(8 - 10)和CPQ(11 - 14)）以及相应的家长感知问卷（PPQ）在南澳大利亚普通儿童人群样本中的信度和效度。
该研究嵌套于儿童口腔健康研究中。在2002/03年，约1401名8至13岁的儿童参与了研究。要求儿童根据年龄完成CPQ(8 - 10)和CPQ(11 - 14)，同时家长完成PPQ。问卷包括对口腔健康和总体幸福感的整体评分。计算了四个领域（口腔症状、功能限制、情绪幸福感和社会幸福感）的得分。收集了每个儿童的龋齿经历（龋坏、缺失和补牙的牙面数量）和咬合特征数据（使用牙科美学指数）。
CPQ问卷和PPQ问卷在针对口腔健康和总体幸福感的整体评分方面显示出可接受的内部一致性和结构效度。龋齿较多或咬合特征不太理想的儿童报告的OHRQoL较差，这确立了这些工具的区分效度。儿童的家长报告的儿童OHRQoL相似。
这些结果表明，这些工具在测量普通人群中儿童的OHRQoL方面具有信度和效度。
