Abstract: With the increasing complexity of ecological and environmental problems, eco-anxiety is increasingly recognized as an essential problem in China. Despite its prevalence, there is a lack of valid measurements in China. The purpose of the present study was to expand the Hogg Eco-anxiety Scale (HEAS) under the Chinese context and evaluate the psychometric attributes of the expanded scale. Specifically, a qualitative study was conducted in Study 1 (n = 17) to expand the HEAS in the Chinese context. Exploratory factor analysis in Study 2 (n = 297) and confirmatory factor analysis in Study 3 (n = 374) were conducted to validate the scale. The climate change anxiety scale and pro-environmental behavior scale were used to assess criterion-related validity in Study 4 (n = 305). Results indicated that a new eco-anxiety scale (i.e., EAS-20) including 20 items attributed to four dimension (somatic symptoms, affective symptoms, rumination, and behavioral symptoms) was developed. It showed satisfactory psychometric properties, including high internal consistency (α = 0.97) and a four-factor structure explaining 84.36% of the variance. The criterion-related validity was acceptable (0.25 ≤ r ≤ 0.37). The article concludes that the 20-item Eco-Anxiety Scale (EAS-20) has good psychometric properties and can be applied to measure eco-anxiety in the Chinese adult population.
