Abstract

The environmental health literacy (EHL) scale evaluates media-specific and general EHL levels in three domains: knowledge, attitude, and behavior. This study aimed to adapt the EHL scale developed by Lichtveld et al. into the Korean language (K-EHL scale) and to verify its reliability and validity. Survey data was collected from 492 adults (19–65 years) residing in Korea. The study process included translation procedures, content validity verification, pre-testing, the actual survey, and statistical analysis for validation and selection of the final items. The scale-level content validity index was 0.92, and one item was removed. Multiple exploratory factor analyses condensed the K-EHL into 2 factors and 38 items. The “Environmental health knowledge and attitude” factor (14 items) measures information, feelings, and thoughts about environmental health. The “Environmental health behavior” factor (24 items) comprises behaviors responding to environmental health. A construct validity (criterion and discriminant validity) was verified using confirmatory factor analysis for goodness of fit (CFI = 0.901, TLI = 0.863, GFI = 0.923, NFI = 0.862, and RMSEA = 0.08). Internal consistency reliability test results showed a Cronbach’s α of 0.81 for the total items. This study is the first to introduce the EHL in Korea, and it also presents a validated evaluation tool. The K-EHL is expected to elucidate EHL levels in Korea. In the future, the EHL scale can be enhanced using this tool.
