简式韧性量表在中国社区老年人中的信效度检验

Reliability and Validity Test of Chinese Version of Brief Resilience Scale for Community Elderly

目的:探讨简式韧性量表(Brief Resilience Scale,BRS)在中国社区老年人群体中应用的信度与效度,为研究我国老年人的心理韧性提供可靠测量工具。方法:对湖南省557名60岁以上的社区老年人进行问卷调查,通过Cronbach’s α系数、探索性因子分析、验证性因子分析、校标效度来检验量表的信度与效度。结果:中文版BRS的Cronbach’s α系数为0.769,有较好的内部一致性。探索性因子分析的结果显示量表为单因子结构,各条目的因子载荷分别为0.718、0.584、0.736、0.757、0.602和0.672,均在0.50以上;验证性因子分析的结果显示:χ^(2)/df=1.55、GFI=0.983、CFI=0.985、RMSEA=0.044、IFI=0.985、AGFI=0.960、PGFI=0.421、PNFI=0.575,说明各项指标拟合程度均较好;以Ego Resiliency Scale(ER89)作为效标,两者之间的相关系数达到0.345。结论:中文版简式韧性量表是一种有效、可靠的心理韧性工具,可以作为评估我国老年人的心理韧性的一个有效测量工具。

Objective: To explore the validity and reliability of Brief Resilience Scale(BRS) in community elderly people in China and provide a reliable measuring tool for studying mental toughness of elderly people in China. Methods: 557 community elderly people over 60 years old in Hunan Province were surveyed by the questionnaire, and the validity and reliability of the scale were tested by Cronbach’s α coefficient, exploratory factor analysis, confirmatory factor analysis and criterion validity. Results: Cronbach’s α coefficient of BRS of Chinese version was 0.769, demonstrating good internal consistency. The result of exploratory factor analysis supported a single-factor structure, and the factor loading of each item was 0.718, 0.584, 0.736, 0.757, 0.602 and 0.672, greater than 0.50. The results of confirmatory factor analysis were χ2/df=1.55, GFI=0.983, CFI=0.985, RMSEA=0.044, IFI=0.985, AGFI=0.960, PGFI=0.421 and PNFI=0.575, suggesting that the fitting degree of each index was good. Taking Ego Resiliency Scale(ER89) as the criterion, the correlation coefficient between the two reached 0.345. Conclusion: BRS of Chinese version is an effective and reliable mental toughness tool, which can be used as an effective measuring tool to evaluate mental toughness of elderly people in China.
