The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory factor analysis was applied to the WAIS-IV/WMS-IV Adult battery (i.e., age 16-69 years) co-norming sample (n = 900) to test 13 measurement models. The results indicated that two models fit the data equally well. One model is a seven-factor solution without a hierarchical general ability factor: Verbal Comprehension, Perceptual Reasoning, Processing Speed, Auditory Working Memory, Visual Working Memory, Auditory Memory, and Visual Memory. The second model is a five-factor model composed of Verbal Comprehension, Perceptual Reasoning, Processing Speed, Working Memory, and Memory with a hierarchical general ability factor. Interpretative implications for each model are discussed.
韦氏成人智力量表第四版（WAIS-IV）和韦氏记忆量表第四版（WMS-IV）共同开发，可单独使用或作为组合测试套件使用。每个测试的独立因素结构已经确定；但是，组合因素结构尚未确定。验证性因子分析应用于 WAIS-IV/WMS-IV 成人电池（即 16-69 岁）共同标准化样本（n=900），以测试 13 个测量模型。结果表明，有两个模型同样适用于数据。一个模型是一个没有层级一般能力因素的七因素解决方案：言语理解、知觉推理、加工速度、听觉工作记忆、视觉工作记忆、听觉记忆和视觉记忆。第二个模型是由言语理解、知觉推理、加工速度、工作记忆和记忆组成的五因素模型，具有层级一般能力因素。对每个模型的解释意义进行了讨论。
