目前，公众可以在网上获得大量的健康信息和健康管理工具。为了最大限度地发挥这些电子健康技术的好处，重要的是要评估个人的电子健康素养。电子健康素养量表（eHEALS）在过去几年中得到了广泛的使用，但主要是在年轻人群中。本研究的目的是使用二次数据分析（N = 866，平均年龄62.8 ± 8.5岁）测试老年人使用eHEALS的心理测量学方面。通过计算α系数和进行重测程序来检查eHEALS的可靠性。其效度采用探索性因素分析和假设检验程序进行评估。结果表明，eHEALS具有内部一致性（α = 0.94）和稳定性（t [244] =-1.48，p = 0.140）。探索性因素分析得出单因素结构解释了67.3%的方差。假设检验也支持eHEALS的有效性。近年来，人们做出了很大努力，利用电子保健干预措施让患者参与医疗保健，并帮助他们管理自己的健康。我们的研究表明，eHEALS是一种用于电子健康素养的简短筛查工具，可以成功地用于老年人。
Currently, vast amounts of health information and health management tools are available to the public online. To maximize the benefits of these eHealth technologies, it is important to assess the eHealth literacy of individuals. The eHealth Literacy Scale (eHEALS) has been used widely in the past several years, but mainly in younger populations. The purpose of this study was to test the psychometric aspects of the eHEALS for older adults using a secondary data analysis (N = 866, mean age, 62.8 ± 8.5 years). Reliability of the eHEALS was examined by calculating alpha coefficients and conducting test-retest procedures. Its validity was assessed using exploratory factor analysis and the hypothesis testing procedure. Findings demonstrated that eHEALS was internally consistent (α = .94) and stable (t [244] = −1.48, p = .140). The exploratory factor analysis yielded a single factor structure explaining 67.3% of the variance. The hypothesis testing also supported the validity of eHEALS. In recent years, there have been great efforts to use eHealth interventions to engage patients in health care and to help them manage their own health. Our study suggests that the eHEALS, a short screening tool for eHealth literacy, can be successfully used for older adults.
