Health literacy, an important factor in public and personal health, is regarded as the core of patient-centered care. Older people with high health literacy are more likely to maintain a healthier lifestyle, with good control and management of chronic diseases, than those lacking or with poor health literacy. The present study investigated the validity and reliability of the Taiwan Longitudinal Study on Aging (TLSA) Health Literacy Scale. We also evaluated the health literacy of middle-aged and older Taiwanese adults, and its probable association with health outcomes and life satisfaction. We analyzed the internal consistency reliability of the nine items of the 2015 TLSA Health Literacy Scale, and their relationship with the demographic variables. Brody Instrumental Activities of Daily Living (IADL) and the Life Satisfaction Index were used for criterion validity. Moreover, exploratory factor analysis was used to examine the construct validity and to test the known-group validity. The TLSA health literacy scale has good internal consistency reliability. Criterion-related validity was supported by the fact that the health literacy score was significantly correlated with the IADL and Life Satisfaction Index. Factor analysis indicated a three-factor structure. Known-group validity was supported by the results, showing that middle-aged and older people with good self-reported health status had better health literacy. The TLSA health literacy scale is a reliable and valid instrument for measuring health literacy in middle-aged and older people.
健康素养是公共和个人健康的一个重要因素，被视为以患者为中心的医疗护理的核心。与健康素养欠缺或较低的老年人相比，健康素养高的老年人更有可能保持更健康的生活方式，对慢性病进行良好的控制和管理。本研究调查了台湾地区老年纵向研究（TLSA）健康素养量表的有效性和可靠性。我们还评估了台湾中年及老年成年人的健康素养，及其与健康结果和生活满意度之间可能存在的关联。我们分析了2015年TLSA健康素养量表九个项目的内部一致性可靠性，以及它们与人口统计学变量之间的关系。使用布罗迪日常生活能力量表（IADL）和生活满意度指数进行效标效度检验。此外，采用探索性因素分析来检验结构效度并测试已知群组效度。TLSA健康素养量表具有良好的内部一致性可靠性。健康素养得分与IADL和生活满意度指数显著相关，这一事实支持了效标关联效度。因素分析表明该量表具有三因素结构。结果支持了已知群组效度，表明自我报告健康状况良好的中年及老年人具有更高的健康素养。TLSA健康素养量表是测量中年及老年人健康素养的一种可靠且有效的工具。
