繁殖感问卷(LGS)在中国老年人群体中的修订及信效度检验

Revision and Reliability-Validity Test of the Loyola Generativity Scale (LGS) in Chinese Elderly

摘要: 目的：将繁殖感问卷(LGS)在中国老年人群体中进行修订，并检验其信效度。方法：采用半结构式访谈、专家评估和问卷调查法等对LGS进行修订，并分别在256名老年人和300名老年人中进行问卷初测和再测。结果：修订后的问卷具有较好信度，量表总体Cronbach’s α = 0.92，各维度Cronbach’s α系数均在0.69~0.85之间；探索性和验证性因素分析的结果表明，修订问卷具有良好的结构效度，条目在所属因子上的因素载荷均超过0.57，验证性因素分析的拟合指标也均符合心理学领域的要求；修订问卷具有较好的效标关联效度，各维度分数及问卷总分与效标问卷分数均显著正相关，相关系数r在0.47~0.69之间。结论：修订后的繁殖感量表具有较好的心理测量学属性，可以作为评定我国老年人繁殖感的有效工具。

Abstract: Objective: To revise the Loyola Generativity Scale (LGS) for the elderly in China and examine its reliability and validity. Methods: The LGS was revised using semi-structured interviews, expert evaluation, and questionnaire surveys. The initial and retest of the questionnaire were conducted among 256 elderly individuals and 300 elderly individuals respectively. Results: The revised scale showed good reliability, with an overall Cronbach’s α of 0.92, and Cronbach’s α for each dimension ranging from 0.69 to 0.85. Exploratory and confirmatory factor analysis results indicated good construct validity: the factor loadings of items on their respective factors exceeded 0.57. Additionally, the confirmatory factor analysis fit indices also met the required standards for psychological measurement. The revised scale also showed good criterion-related validity, as the scores of each dimension and the total score were significantly positively correlated with the criterion measure, with correlation coefficients ranging from 0.47 to 0.69. Conclusion: The revised Loyola Generativity Scale has good psychometric properties and can serve as an effective tool for assessing generativity in Chinese elderly.
