(1) Background: Environmental issues are among society's most pressing concerns as they can significantly impact the environment and human health. The Eco Generativity Scale (EGS), a 28-item four-factor scale has been introduced to promote a constructive outlook on the matter. It encompasses two types of generativity, namely ecological and social generativity, as well as environmental identity and agency/pathways. The aim of the current study was to examine the EGS's psychometric properties among 375 Italian university students. (2) Methods: To evaluate the scale's factor structure, both exploratory and confirmatory factor analyses were conducted. Internal consistency was evaluated via Cronbach's alphas and McDonald's omega. Concurrent validity was analyzed with the Positive and Negative Affect Scale (PANAS), Satisfaction with life Scale (SWLS), Meaningful Life Measure (MLM), and Flourishing Scale (FS). (3) Results: The exploratory factor analysis showed the best fit for a four-factor solution. Confirmatory factor analysis revealed that a four-factor higher-order model provided the best fit to the data with good internal consistency. Furthermore, each factor and the total score showed a good concurrent validity with the PANAS, SWLS, MLM, and FS. (4) Conclusions: The Eco-Generativity Scale (EGS) showed good psychometric properties for its use in research and intervention as a promising tool to measure eco-generativity.
(1) 背景：环境问题是社会最紧迫的关切之一，因为它们会对环境和人类健康产生重大影响。生态生成性量表（EGS）是一个包含28个项目的四因素量表，已被引入以促进对该问题形成建设性的看法。它涵盖两种类型的生成性，即生态生成性和社会生成性，以及环境认同和能动性/途径。本研究的目的是检验375名意大利大学生中EGS的心理测量特性。(2) 方法：为了评估该量表的因子结构，进行了探索性和验证性因子分析。通过克朗巴哈系数和麦克唐纳ω系数评估内部一致性。使用积极和消极情绪量表（PANAS）、生活满意度量表（SWLS）、有意义生活量表（MLM）和蓬勃发展量表（FS）分析同时效度。(3) 结果：探索性因子分析显示四因素解决方案的拟合度最佳。验证性因子分析表明，四因素高阶模型对数据的拟合度最佳，且内部一致性良好。此外，每个因子和总分与PANAS、SWLS、MLM和FS均显示出良好的同时效度。(4) 结论：生态生成性量表（EGS）在作为测量生态生成性的有前景工具用于研究和干预时，显示出良好的心理测量特性。
