The current study examined the psychometric properties of the 20-item Generative Acts Scale-Chinese version (GAS-C) among middle-aged and older adults as grandparents in mainland China. A total of 1013 grandparents (mean age = 58.32 years; 71.9% female) of children from 12 kindergartens were recruited using multistage cluster random sampling. A four-factor pattern of domestic, agentic, communal, and civic generative acts were identified by exploratory factor analysis and further verified by confirmatory factor analysis (CFA). Subsequently, multigroup CFA was performed to test the measurement invariance across gender, age group and status at the configural, metric, and scalar levels. The Cronbach's alpha value of the total (0.923) and subscales (range from 0.897 to 0.953) was satisfactory, indicating high internal consistency. Additionally, the significant gender differences in the domestic (male = 3.565, female = 3.718, < 0.05), communal (male = 2.786, female = 2.591, < 0.01), and civic subscales (male = 2.112, female = 1.864, < 0.001) and the significant correlations between the GAS-C total scale and subscales with caregiving intensity ( = 0.433, < 0.01), positive affect ( = 0.397, < 0.01) and life satisfaction ( = 0.328, < 0.01), supported concurrent validity. Overall, this study addressed the knowledge gap by validating a reliable and valid instrument to measure grandparents' generative acts in mainland China, contributing to generativity studies cross-culturally in research and practice.
本研究旨在检验中文版生成性行为量表（GAS-C）在中国大陆作为祖辈的中老年人群中的心理测量学特性。采用多阶段聚类随机抽样的方法，共招募了 12 所幼儿园的 1013 位祖辈（平均年龄=58.32 岁，71.9%为女性）。通过探索性因素分析，确定了家庭、代理、社群和公民生成性行为的四因子模式，随后通过验证性因素分析（CFA）进一步验证。随后，进行了多组 CFA，以检验性别、年龄组和身份在组态、度量和标度水平上的测量不变性。总量表（0.923）和分量表（范围从 0.897 到 0.953）的 Cronbach's alpha 值均令人满意，表明具有较高的内部一致性。此外，在家庭（男性=3.565，女性=3.718， < 0.05）、社群（男性=2.786，女性=2.591， < 0.01）和公民分量表（男性=2.112，女性=1.864， < 0.001）上存在显著的性别差异，以及 GAS-C 总量表和分量表与照顾强度（ = 0.433， < 0.01）、积极情感（ = 0.397， < 0.01）和生活满意度（ = 0.328， < 0.01）之间的显著相关性，支持了同时效度。总的来说，本研究通过验证一种可靠和有效的工具来测量中国大陆祖辈的生成性行为，填补了知识空白，为跨文化的生成性研究在研究和实践中做出了贡献。
