In this digital era, eHealth literacy is an essential skill set to leverage health information available online to promote health outcomes. South Korea has an advanced health information technology infrastructure, including widespread use of the internet and mobile phones. A few studies have explored eHealth literacy in South Korea using translated versions of the eHEALS; however, they were not fully validated. A unified reliable and valid assessment tool is critical to assess and enhance the eHealth literacy level across the population.
The aim was to develop a Korean version of eHealth Literacy Scale (K-eHEALS) and evaluate its reliability and validity employing healthy young adults in Korea.
The K-eHEALS was developed based on eHEALS, a widely used tool that measures eHealth literacy, and was validated using a sample of 500 young adults recruited from a pool of a Korean internet survey panel. Content validity was assessed using the content validity index (CVI) for individual items and for scale. Construct validity was examined using exploratory factor analysis and hypothesis testing. The Cronbach alpha coefficient was used to determine the internal consistency and the Pearson correlation coefficient was used to evaluable the stability of the measure (n=55).
Both individual and scale CVIs were acceptable (individual CVIs>0.67; scale CVI=0.83). Single factors accounting for 50.3% of the variance in the scales were extracted revealing the unidimensional latent structure of K-eHEALS. Hypothesis testing showed significant association between eHealth literacy and hours of internet use per day, supporting the construct validity. Items of the K-eHEALS were internally consistent (Cronbach alpha=.88) and stable over a 1-month period (r=.754, P<.001).
The findings of this study suggest that K-eHEALS is a valid and reliable measure of eHealth literacy in Korean young adults. Additional studies are needed with more diverse groups of adults in Korea.
在这个数字时代，电子健康素养是利用在线可得的健康信息以促进健康结果的一项基本技能组合。韩国拥有先进的健康信息技术基础设施，包括互联网和手机的广泛使用。一些研究使用电子健康素养量表（eHEALS）的翻译版本对韩国的电子健康素养进行了探索；然而，这些研究并未得到充分验证。一个统一的可靠且有效的评估工具对于评估和提高全体人群的电子健康素养水平至关重要。
旨在开发韩国版电子健康素养量表（K-eHEALS），并在韩国健康的年轻成年人中评估其信度和效度。
K-eHEALS是基于eHEALS开发的，eHEALS是一种广泛用于测量电子健康素养的工具，并使用从韩国互联网调查小组中招募的500名年轻成年人样本进行了验证。使用单个项目和量表的内容效度指数（CVI）评估内容效度。使用探索性因子分析和假设检验检查结构效度。使用Cronbach α系数确定内部一致性，并使用Pearson相关系数评估该测量方法的稳定性（n = 55）。
单个项目和量表的CVI均可接受（单个项目CVI>0.67；量表CVI = 0.83）。提取了占量表方差50.3%的单一因素，揭示了K-eHEALS的单维潜在结构。假设检验表明电子健康素养与每天上网时间之间存在显著关联，支持结构效度。K-eHEALS的项目内部一致（Cronbach α = 0.88），并且在1个月内保持稳定（r = 0.754，P <.001）。
本研究结果表明，K-eHEALS是测量韩国年轻成年人电子健康素养的有效且可靠的工具。韩国需要对更多不同成年人群体进行进一步研究。
