This study presents the Brazilian short form of the P-CPQ.
Data from a representative sample of 702 parents/caregivers of children were randomly divided in two subsamples. A development sample (n = 502) was used for exploratory factor analysis (EFA), and a validation sample (n = 200) was used for confirmatory factor analysis (CFA). The EFA was used to determine the hypothetical factor structure and internal consistency. The CFA was applied to test the factor structure of the original P-CPQ, alternative models and the validity and reliability of the Brazilian short form of the P-CPQ.
A 3-factor model (alternative model 2) had a factor structure with high factor loadings, acceptable fit indices (χ(2)/df = 2.38; GFI = 0.90; CFI = 0.90; TLI = 0.87; AGFI = 0.85; SRMR = 0.07) and both convergent and discriminant validity (Pearson bivariate zero order correlations among factors <0.85).
The Brazilian P-CPQ with three subscales and 13 items appears to be a valid short version to be used in further studies to evaluate parents/caregivers' perceptions of children's oral health-related quality of life.
本研究介绍了 P-CPQ 的巴西短式版本。
从 702 名儿童的父母/照顾者的代表性样本中随机分为两个子样本。一个发展样本（n = 502）用于探索性因素分析（EFA），验证样本（n = 200）用于验证性因素分析（CFA）。EFA 用于确定假设的因素结构和内部一致性。CFA 用于检验 P-CPQ 的原始、替代模型的因素结构，以及巴西 P-CPQ 短式版本的有效性和可靠性。
三因素模型（替代模型 2）的因素结构具有较高的因素负荷，可接受的拟合指数（χ2/df = 2.38；GFI = 0.90；CFI = 0.90；TLI = 0.87；AGFI = 0.85；SRMR = 0.07），以及良好的收敛和判别效度（因素间的 Pearson 双变量零阶相关系数 <0.85）。
巴西 P-CPQ 有三个分量表和 13 个项目，似乎是一个有效的简短版本，可以在进一步的研究中用于评估父母/照顾者对儿童口腔健康相关生活质量的看法。
