Specific measures to evaluate positive oral health have been in a nascent stage in Dentistry, especially in developing countries. The present study aimed to translate, cross-culturally adapt and evaluate the psychometric properties of the Brazilian version of Positive Oral Health and Well-Being (B-POHW). After forward-backwards translation to Brazilian Portuguese language, the cross-cultural adaptation of B-POHW was pretested, followed by the main study to perform psychometric analysis. We tested the model fit by Confirmatory Factor Analysis with categorical factor indicators in bifactor and simple structure models on a sample of 209 participants (mean age: 39.36 ± 12.26. Questionnaires about sociodemographic status, self-reported oral health-related outcomes, and general well-being were administered and used as external validation measures. Moreover, dental caries experience was clinically diagnosed. For test-retest reliability, 53 participants completed the B-POHW a fortnight later. The following results were found: a) the bifactor model presented the best model fit; b) the B-POHW demonstrated satisfactory internal consistency (Cronbach's α and McDonald's ω > 0.8); c) the intraclass correlation coefficient suggested good reliability for the Global Factor of B-POHW in the test-retest (ICC = 0.84); d) evidence based on other variables and construct representation was in line with the positive oral health framework. The B-POHW is psychometrically sound to be used in a Brazilian context, and evidence of its internal structure confirmed its theoretical framework for measuring positive oral health. These findings advance in holistic approaches, enabling to assess positive oral health in Dental practice in Brazil.
特定的评估积极口腔健康的措施在口腔医学领域仍处于初级阶段，尤其是在发展中国家。本研究旨在翻译、跨文化调适并评估巴西版积极口腔健康和幸福感量表（B-POHW）的心理计量特性。经过正向和反向翻译为巴西葡萄牙语后，对 B-POHW 进行了预测试，随后进行了主要研究以进行心理计量分析。我们使用二分法和简单结构模型的类别因子指标，对 209 名参与者的样本进行了验证性因子分析来检验模型拟合度。参与者的平均年龄为 39.36±12.26 岁，他们完成了关于社会人口统计学状况、自我报告的口腔健康相关结果和总体幸福感的问卷，这些问卷被用作外部验证措施。此外，还对龋齿患病情况进行了临床诊断。为了评估重测信度，53 名参与者在两周后完成了 B-POHW。结果如下：a）二分法模型表现出最佳的模型拟合度；b）B-POHW 表现出令人满意的内部一致性（Cronbach's α 和 McDonald's ω>0.8）；c）在重测中，B-POHW 的总体因子的组内相关系数表明具有良好的可靠性（ICC=0.84）；d）基于其他变量和结构表现的证据与积极口腔健康框架一致。B-POHW 在巴西背景下具有良好的心理计量学特性，其内部结构的证据证实了其用于衡量积极口腔健康的理论框架。这些发现促进了整体方法的发展，使巴西口腔医学实践中能够评估积极的口腔健康。
