This investigation of the Life Satisfaction Index (LSI) supports findings by Hoyt and Creech (1983) that indicate Adams' (1969) proposed factor structure is not invariant across groups. Two reduced factor models, proposed by Hoyt and Creech and based on a subset of LSI items, were studied with our sample (two levels each of income and age, N = 791). Our work confirms that the Hoyt and Creech 8-item LSI reveals the more stable factor structure of those examined. In addition, we found that the 8-item index has adequate statistical power to be of benefit to those investigators looking at quantitative differences in life satisfaction, with reasonable assurance that older and/or higher-income individuals are interpreting the items in similar ways.
这项关于生活满意度指数（LSI）的调查支持了霍伊特和克里奇（1983年）的研究结果，即亚当斯（1969年）提出的因素结构在不同群体中并非不变。霍伊特和克里奇提出的两个简化因素模型，基于LSI项目的一个子集，在我们的样本（收入和年龄各两个水平，N = 791）中进行了研究。我们的工作证实，霍伊特和克里奇的8项LSI揭示了所考察的因素结构中更稳定的结构。此外，我们发现8项指数具有足够的统计效力，有助于那些研究生活满意度定量差异的研究者，并有合理的把握认为年龄较大和/或收入较高的个体以相似的方式解释这些项目。
