During the standardization of the Wechsler Adult Intelligence Scale (3rd ed.; WAIS-III) and the Wechsler Memory Scale (3rd ed.; WMS-III) the participants in the normative study completed both scales. This "co-norming" methodology set the stage for full integration of the 2 tests and the development of an expanded structure of cognitive functioning. Until now, however, the WAIS-III and WMS-III had not been examined together in a factor analytic study. This article presents a series of confirmatory factor analyses to determine the joint WAIS-III and WMS-III factor structure. Using a structural equation modeling approach, a 6-factor model that included verbal, perceptual, processing speed, working memory, auditory memory, and visual memory constructs provided the best model fit to the data. Allowing select subtests to load simultaneously on 2 factors improved model fit and indicated that some subtests are multifaceted. The results were then replicated in a large cross-validation sample (N = 858).
在韦氏成人智力量表（第3版；WAIS - III）和韦氏记忆量表（第3版；WMS - III）的标准化过程中，常模研究的参与者完成了这两个量表。这种“共同常模”方法为这两项测试的全面整合以及认知功能扩展结构的发展奠定了基础。然而，到目前为止，WAIS - III和WMS - III尚未在一项因素分析研究中一起进行检验。本文呈现了一系列验证性因素分析，以确定WAIS - III和WMS - III的联合因素结构。使用结构方程建模方法，一个包含言语、知觉、加工速度、工作记忆、听觉记忆和视觉记忆结构的六因素模型对数据提供了最佳拟合。允许选定的子测验同时在两个因素上负荷，改善了模型拟合，并表明一些子测验具有多面性。然后在一个大型交叉验证样本（N = 858）中复制了这些结果。
