Comparing Factors Associated With eHealth Literacy Between Young and Older Adults

The purpose of the current study was to compare the factors associated with adults' eHealth literacy, which is vital for health consumers. A secondary data analysis was conducted with data collected from November 2017 to February 2018 for a project on the development of a Korean version of the eHealth Literacy Scale. Participants were recruited through an online survey for young adults (n = 210, mean age = 25.5 [SD = 4.7] years) and a face-to-face survey for older adults (n = 187, mean age = 73.2 [SD = 4.8] years). Hierarchical multiple regression analyses were used to analyze data and determine eHealth literacy predictors. Older adults held more positive attitudes toward internet health information than young adults (mean = 16.49 [SD = 2.54] and 17.04 [SD = 2.41], respectively; p = 0.029); however, eHealth literacy levels were comparable (mean = 30.50 [SD = 4.62] and 30.95 [SD = 4.17], respectively; p = 0.305). Attitude toward internet health information was a significant predictor of eHealth literacy in both groups, and age was only a predictor among young adults. These results elucidate predictors of eHealth literacy and inform strategies to improve eHealth literacy among young and older adults.
