Recent studies of autism and schizophrenia examining the factor structure of the subtests of the Wechsler Adult Intelligence Scale-Revised have identified a factor that is thought to assess social cognitive (SC) processes or social context. The objective of the current study was to determine whether a similar factor could be identified using confirmatory factor analysis of the 14 Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) subtests in the standardization sample. A five-factor model that included an SC factor along with verbal comprehension, perceptual organization, working memory, and processing speed factors provided the best fit of the data. The SC factor was composed of the Picture Arrangement, Picture Completion, and Object Assembly subtests when all 14 WAIS-III subtests were included. These results provide support for the construct validity of SC factors measured by the WAIS-III in the standardization sample, although additional research is necessary to determine its stability across age groups and clinical populations, as well as its sensitivity to various forms of brain dysfunction.
近期针对自闭症和精神分裂症的研究，对韦氏成人智力量表修订版各分测验的因素结构进行了考察，识别出了一个被认为可评估社会认知（SC）过程或社会情境的因素。本研究的目的是，通过对标准化样本中韦氏成人智力量表第三版（WAIS - III）的14个分测验进行验证性因素分析，来确定是否能识别出类似的因素。一个包含SC因素以及言语理解、知觉组织、工作记忆和加工速度因素的五因素模型对数据拟合最佳。当纳入全部14个WAIS - III分测验时，SC因素由图片排列、图片补缺和物体拼凑分测验构成。这些结果为WAIS - III在标准化样本中测量的SC因素的结构效度提供了支持，不过仍需进一步研究以确定其在不同年龄组和临床群体中的稳定性，以及其对各种形式脑功能障碍的敏感性。
