Confirmatory Factor Analyses (CFA) of the Wechsler Adult Intelligence Scale-III (WAIS-III) lend partial support to the four-factor model proposed in the test manual. However, the Arithmetic subtest has been especially difficult to allocate to one factor. Using the new Norwegian WAIS-III version, we tested factor models differing in the number of factors and in the placement of the Arithmetic subtest in a mixed clinical sample (n = 272). Only the four-factor solutions had adequate goodness-of-fit values. Allowing Arithmetic to load on both the Verbal Comprehension and Working Memory factors provided a more parsimonious solution compared to considering the subtest only as a measure of Working Memory. Effects of education were particularly high for both the Verbal Comprehension tests and Arithmetic.
韦氏成人智力量表第三版（WAIS - III）的验证性因素分析（CFA）为测试手册中提出的四因素模型提供了部分支持。然而，算术分测验尤其难以归为一个因素。我们使用挪威WAIS - III新版本，在一个混合临床样本（n = 272）中测试了因素数量以及算术分测验位置不同的因素模型。只有四因素解决方案具有足够的拟合优度值。与仅将该分测验视为工作记忆的一种测量方法相比，允许算术同时加载于言语理解和工作记忆因素上提供了一个更简约的解决方案。教育对言语理解测验和算术的影响都特别大。
