The aim of this study was to evaluate the correlation between the Child Perceptions Questionnaire 8 to 10 (CPQ8-10) and child-Oral Impact on Daily Performances (child-OIDP) indexes according to their total and item scores, as well as assess the discriminative validity of these assessment tools regarding dental caries and malocclusion among schoolchildren. A sample of 300 children aged between 8 and 10 years answered the questionnaires in two distinct steps. First, half of the sample (G1 = 150) answered the CPQ8-10 and the other half (G2 = 150) answered the child-OIDP. A week after, G1 answered the child-OIDP and G2 answered the CPQ8-10. Dental Aesthetic Index and WHO criteria were used to categorize malocclusion and dental caries, respectively. Descriptive analysis, Spearman's correlation and Mann-Whitney test were performed in this study. The CPQ8-10 and child-OIDP demonstrated a statistically significant and moderate correlation between their total scores. Regarding the discriminative validity, CPQ8-10 demonstrated a significant association between the "emotional status" daily activity and dental caries, and between the "eating", "sleeping", and "studying" daily activities and malocclusion. Concerning the child-OIDP, a significant difference was found only between the "social contact" activity and presence of dental caries. Both instruments were not capable of distinguishing children with and without dental caries and/or malocclusion by their total scores. However, the instruments were able to discriminate between children with and without those oral disorders in different dimensions. Thus, the CPQ8-10 and the child-OIDP demonstrated a different capacity to assess the impact on OHRQoL among schoolchildren.
本研究旨在评估儿童感知问卷 8-10 版（CPQ8-10）与儿童口腔健康影响生活质量量表（child-OIDP）的总评分和项目评分之间的相关性，并评估这些评估工具在评估儿童龋病和错颌畸形方面的判别效度。一个由 300 名 8 至 10 岁儿童组成的样本分两步回答问卷。首先，一半样本（G1=150）回答 CPQ8-10，另一半（G2=150）回答 child-OIDP。一周后，G1 回答 child-OIDP，G2 回答 CPQ8-10。使用牙齿美学指数和世界卫生组织标准分别对错颌畸形和龋齿进行分类。本研究进行了描述性分析、Spearman 相关性分析和 Mann-Whitney 检验。CPQ8-10 与 child-OIDP 的总分之间存在统计学上显著的中度相关性。关于判别效度，CPQ8-10 显示“情绪状态”日常活动与龋齿之间，以及“进食”、“睡眠”和“学习”日常活动与错颌畸形之间存在显著关联。关于 child-OIDP，仅在“社交活动”与龋齿存在之间发现显著差异。两种工具都无法根据总分区分有和无龋齿和/或错颌畸形的儿童。然而，这两种工具能够在不同维度区分有和无这些口腔疾病的儿童。因此，CPQ8-10 和 child-OIDP 在评估儿童口腔健康相关生活质量方面具有不同的能力。
