The aim of this study was to translate, culturally adapt, and test the psychometric performance of a questionnaire to assess health literacy. Brazilian university students (n = 472) with a mean age of 22.7 (5.3) years participated in the study. The validities of the factor, convergent, and discriminant structure were tested using structural equations analysis. The 4-factors model showed only fair results, but was nevertheless the most adequate in terms of factor validity and proved invariant in independent samples. Convergent validity was only adequate for the factor "Search for Health Information", while discriminant validity was adequate for the factors "Search for Information" and "Understanding Information". Internal consistency showed adequate results on all the items. The second-order hierarchical model, although not totally adequate, slowly slightly higher fit indices and thus allowed calculating an overall health literacy score considering each item's best weight.
本研究的目的是对一份评估健康素养的问卷进行翻译、文化调适并测试其心理测量性能。平均年龄为22.7（5.3）岁的472名巴西大学生参与了该研究。使用结构方程分析对因子、收敛和判别结构的效度进行了测试。四因子模型的结果仅为尚可，但在因子效度方面却是最适当的，并且在独立样本中证明具有不变性。收敛效度仅在“健康信息搜索”因子上是适当的，而判别效度在“信息搜索”和“信息理解”因子上是适当的。内部一致性在所有项目上都显示出适当的结果。二阶层次模型虽然不完全适当，但拟合指数略高一些，因此可以考虑每个项目的最佳权重来计算总体健康素养得分。
