Examination of measurement invariance tests the assumption that the model underlying a set of test scores is directly comparable across groups. The observation of measurement invariance provides fundamental evidence for the inference that scores on a test afford equivalent measurement of the same psychological traits among diverse groups. Groups may be derived from different psychosocial backgrounds or different clinical presentations. In the Wechsler Adult Intelligence Scale-III (WAIS-III)/Wechsler Memory Scale-III (WMS-III) Technical Manual (Psychological Corporation, 2002), there appears to be a breakdown in factor structure among the standardization cases in older adults. In this study, the authors evaluated the invariance of the measurement model of the WAIS-III across 5 age bands. All components of the measurement model were examined. Overall, the evidence pointed to invariance across age of a modified 4-factor model that included cross-loadings for the Similarities and Arithmetic subtests. These results support the utility of the WAIS-III as a measure of stable intelligence traits across a wide age range.
测量不变性检验的假设是，一组测验分数背后的模型在不同群体间具有直接可比性。测量不变性的观察结果为以下推断提供了基本证据：在不同群体中，测验分数能够对相同的心理特质进行等效测量。群体可能源自不同的社会心理背景或不同的临床表现。在《韦氏成人智力量表第三版（WAIS - III）/韦氏记忆量表第三版（WMS - III）技术手册》（心理公司，2002年）中，老年人标准化样本的因素结构似乎出现了分解。在本研究中，作者评估了WAIS - III测量模型在5个年龄组中的不变性。对测量模型的所有组成部分进行了检验。总体而言，证据表明，一个经过修改的四因素模型在年龄上具有不变性，该模型包括相似性和算术子测验的交叉负荷。这些结果支持了WAIS - III作为在广泛年龄范围内测量稳定智力特质的工具的效用。
