The aim of this study was to analyze the psychometric properties of the Portuguese Brazilian version of the instrument for measuring health literacy European Health Literacy Survey Questionnaire short form (HLS-EU-Q16). The study sample consisted of 783 Brazilian adults with a mean age of 38.6 years. The data were analyzed through an extensive and robust process of testing the properties with the combination of exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and item response theory (IRT) techniques, aiming to search for strong validation evidence in the internal structure and stability step for other sub-samples. The instrument's reliability was tested using Cronbach's alpha and McDonald's Omega. The analyses indicated the existence of only one dimension and good reliability values. The model tested with cross-validation indicated satisfactory, adequate, consistent and stable levels for EFA, IRT via item discrimination and CFA, both for primary indicators as factor loadings, communalities, item discrimination as well as for the model adequacy indicators. It is concluded that the Brazilian Portuguese version of the HLS-EU-Q16 proved to be a one-dimensional, consistent, accurate and stable model for measuring health literacy in Brazilian adults.
本研究旨在分析欧洲健康素养调查问卷短式量表（HLS-EU-Q16）葡萄牙语巴西版本的心理计量学特性。研究样本由 783 名巴西成年人组成，平均年龄为 38.6 岁。通过结合探索性因素分析（EFA）、验证性因素分析（CFA）和项目反应理论（IRT）技术进行广泛而稳健的特性测试，对数据进行了分析，旨在内部结构和稳定性步骤中为其他子样本寻找强有力的验证证据。使用 Cronbach's alpha 和 McDonald's Omega 测试了工具的可靠性。分析表明仅存在一个维度和良好的可靠性值。通过交叉验证测试的模型表明，EFA、IRT 通过项目区分度和 CFA 的主要指标（因子负荷、共性、项目区分度以及模型充分性指标）均具有良好、足够、一致和稳定的水平。结论是，HLS-EU-Q16 的巴西葡萄牙语版本在测量巴西成年人的健康素养方面是一个一致、准确和稳定的单维模型。
