We address two questions of central interest in adult intellectual development: the equivalence of psychometric tests' measurement properties at different ages, and the stability of individual differences in intelligence over time. We performed a series of longitudinal factor analyses using the LISREL program to model longitudinal data from Schaie's Seattle Longitudinal Study. The results indicate complete invariance in the loadings of five subtests of Thurstone's Primary Mental Abilities battery on a general intelligence factor. Individual differences in general intelligence were highly stable over 14-year epochs, with standardized factor correlations averaging about .9 between adjacent 7-year testing intervals. These results indicate that most individuals in this relatively select longitudinal sample maintained their relative ordering in intelligence.
不同年龄阶段心理测量测试的测量属性的等效性，以及智力方面个体差异随时间的稳定性。我们使用LISREL程序进行了一系列纵向因素分析，以对来自沙伊的西雅图纵向研究的纵向数据进行建模。结果表明，瑟斯顿基本心理能力量表的五个子测试在一般智力因素上的载荷完全不变。一般智力的个体差异在14年的时间段内高度稳定，相邻7年测试间隔之间的标准化因素相关性平均约为0.9。这些结果表明，在这个相对有选择性的纵向样本中，大多数个体在智力方面保持了他们的相对排序。
