Abstract

Currently, vast amounts of health information and health management tools are available to the public online. To maximize the benefits of these e-health technologies, it is important to assess the e-health literacy of individuals. The eHealth Literacy Scale 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 eHealth Literacy Scale for older adults using a secondary data analysis (N = 866; mean age, 62.8 +/- 8.5 years). Reliability of the eHealth Literacy Scale 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 eHealth Literacy Scale was internally consistent ([alpha] = .94) and stable (t244 = -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 eHealth Literacy Scale. In recent years, there have been great efforts to use e-health interventions to engage patients in healthcare and to help them manage their own health. Our study suggests that the eHealth Literacy Scale, a short screening tool for e-health literacy, can be successfully used for older adults.
