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 ( = 17) to expand the HEAS in the Chinese context. Exploratory factor analysis in Study 2 ( = 297) and confirmatory factor analysis in Study 3 ( = 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 ( = 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 ≤ ≤ 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.
随着生态与环境问题日益复杂，生态焦虑在中国越来越被视为一个重要问题。尽管其普遍存在，但在中国缺乏有效的测量工具。本研究的目的是在中国背景下扩展霍格生态焦虑量表（HEAS），并评估扩展后量表的心理测量学特性。具体而言，在研究1（n = 17）中进行了一项定性研究，以在中国背景下扩展HEAS。在研究2（n = 297）中进行探索性因素分析，在研究3（n = 374）中进行验证性因素分析，以验证该量表。在研究4（n = 305）中使用气候变化焦虑量表和亲环境行为量表来评估效标关联效度。结果表明，开发了一个新的生态焦虑量表（即EAS - 20），包括20个项目，归为四个维度（躯体症状、情感症状、沉思和行为症状）。它显示出令人满意的心理测量学特性，包括高内部一致性（α = 0.97）和一个四因素结构，解释了84.36%的方差。效标关联效度是可接受的（0.25≤r≤0.37）。文章得出结论，20项生态焦虑量表（EAS - 20）具有良好的心理测量学特性，可用于测量中国成年人群的生态焦虑。
