The goal of this study was to adapt, improve and validate a short, self-administered health literacy assessment tool for European Portuguese-speaking adults. Health literacy tools are of great importance to health authorities and professionals, as low or inadequate health literacy, that is, a limited capacity to handle health-related information, is associated with higher morbidity and mortality. The 18-item Short Assessment of Health Literacy for Brazilian Portuguese-speaking adults (SAHLPA-18) was adapted into European Portuguese. The European Portuguese tool (SAHLPA-23) includes five additional items. The SAHLPA-23 was tested in a convenience sample of 503 participants from two Portuguese regions. Socio-demographic data, literacy and cognitive indicators were collected. Participants also completed a questionnaire on comprehension of written health materials. Construct validity was assessed through correlations between SAHLPA-23 scores and education, literacy, and cognitive variables and score on the comprehension questionnaire. The psychometric properties of the new tool were compared with those of the SAHLPA-18. The mean SAHLPA-18 and SAHLPA-23 scores were 13.9 (77.2%; SD=2.9) and 18.3 (79.6%; SD=3.8), respectively. Both tools showed adequate reliability (Cronbach's α>0.7). SAHLPA-23 was more highly correlated with all study variables than SAHLPA-18. Although both instruments displayed acceptable discriminative power, SAHLPA-23 had better accuracy than SAHLPA-18 (DeLong's method: ΔAUC=0.09, Z=3.36; P<0.001). The SAHLPA-23 is an independent, feasible and innovative tool for estimation of health literacy in the Portuguese adult population.
本研究的目的是改编、改进并验证一种针对欧洲葡萄牙语成年人的简短、自我管理的健康素养评估工具。健康素养工具对卫生当局和专业人员非常重要，因为健康素养低或不足，即处理与健康相关信息的能力有限，与较高的发病率和死亡率相关。针对巴西葡萄牙语成年人的18项健康素养简短评估工具（SAHLPA - 18）被改编为欧洲葡萄牙语版本。欧洲葡萄牙语工具（SAHLPA - 23）增加了五个项目。SAHLPA - 23在来自葡萄牙两个地区的503名参与者的便利样本中进行了测试。收集了社会人口统计学数据、识字和认知指标。参与者还完成了一份关于书面健康材料理解的问卷。通过SAHLPA - 23得分与教育、识字、认知变量以及理解问卷得分之间的相关性来评估结构效度。将新工具的心理测量特性与SAHLPA - 18的进行了比较。SAHLPA - 18和SAHLPA - 23的平均得分分别为13.9（77.2%；标准差 = 2.9）和18.3（79.6%；标准差 = 3.8）。两种工具都显示出足够的可靠性（Cronbach's α>0.7）。SAHLPA - 23与所有研究变量的相关性都比SAHLPA - 18更高。尽管两种工具都显示出可接受的区分能力，但SAHLPA - 23比SAHLPA - 18具有更好的准确性（DeLong方法：ΔAUC = 0.09，Z = 3.36；P<0.001）。SAHLPA - 23是一种用于评估葡萄牙成年人群健康素养的独立、可行且创新的工具。
