Abstract

Purpose

The purpose of this study was to cross-culturally adapt the eHealth Literacy Scale into Korean (KeHEALS) and evaluate its reliability and validity.

Methods

The cross-cultural adaptation of the KeHEALS was conducted according to the World Health Organization's guideline. To evaluate the reliability and validity, the data of 397 participants (210 young adults and 187 older adults) were collected from 2017 November to 2018 February. An online survey was conducted with young adults, while a face-to-face survey was conducted with older adults in two senior welfare centers. The reliability of the KeHEALS was examined using the internal consistency and test-retest reliability tests. Regarding the validity, the content validity index was calculated for content validity, and exploratory and confirmatory factor analyses and the hypothesized test were conducted for assessing construct validity of the KeHEALS.

Results

The Cronbach's α coefficient was .89 and the intraclass correlation coefficient for the 2-week test-retest reliability was .80. The content validity index of the KeHEALS was 1.0. From the exploratory factor analysis, eight items were retained in one factor, which accounted for 58.1% of the total variance. This factor structure was confirmed by the confirmatory factor analysis. The total score of the KeHEALS was significantly correlated with the attitudes toward internet health information.

Conclusion

The findings of this study provide evidence for the adequate psychometric properties of the KeHEALS. The KeHEALS will be useful to evaluate the eHealth literacy among Koreans.
