The hypothesis that psychometric ability tests retain equivalent factor structures across a 7-year interval was examined in a sample of 984 persons (disaggregated into 6 cohort groups: M ages at first test = 32, 46, 53, 60, 67, and 76), assessed in 1984 and 1991 as part of the Seattle Longitudinal Study. A best fitting measurement model was estimated for 20 psychometric tests marking the 6 primary abilities of Inductive Reasoning, Spatial Orientation, Perceptual Speed, Numeric Facility, Verbal Ability, and Verbal Recall. Gender was partialed out at the variable level by including a gender factor. Weak factorial invariance over time was demonstrated for all cohorts. Configural invariance could be demonstrated across all cohort groups. However, weak factorial invariance across groups could be accepted for all but the youngest and oldest groups. Latent means were modeled for the accepted solutions across time and cohort groups.
作为西雅图纵向研究的一部分，在1984年和1991年对984人（分为6个队列组：首次测试时的平均年龄分别为32岁、46岁、53岁、60岁、67岁和76岁）进行了评估，以检验心理测量能力测试在7年间隔内是否保持等效因素结构这一假设。针对20项心理测量测试估计了最佳拟合测量模型，这些测试标志着归纳推理、空间定向、知觉速度、数字运算、语言能力和语言记忆这6种主要能力。通过纳入性别因素，在变量水平上对性别进行了控制。结果表明，所有队列在不同时间具有弱因素不变性。所有队列组都能证明构型不变性。然而，除最年轻和最年长的组外，所有组之间的弱因素不变性均可接受。针对各时间点和队列组的可接受解决方案建立了潜在均值模型。
