Wechsler Adult Intelligence Scale-Revised subtests, as administered to 204 individuals with low IQs, were factor analyzed. Solutions proved comparable to structures extracted from the normative data and to solutions based on WAIS, WISC-R, and WISC data for persons with low IQs. Given the restricted IQ range and diminished variance involved, this study provides a particularly stringent test of WAIS-R factor structure. Subtest contributions to general intelligence, however, tend to be more similar among samples of persons with low IQs than between the present low IQ sample and the standardization sample. Clinicians working with intellectually low functioning clients can validly make factor-based test interpretations, but use of short-forms may be dangerous.
对204名低智商个体进行了韦氏成人智力量表修订版分测验的因素分析。结果证明，其结果与从常模数据中提取的结构以及基于低智商人群的韦氏成人智力量表、韦氏儿童智力量表修订版和韦氏儿童智力量表数据得出的结果相当。鉴于所涉及的智商范围有限且方差减小，本研究对韦氏成人智力量表修订版的因素结构进行了特别严格的检验。然而，低智商人群样本中各分测验对一般智力的贡献往往比当前低智商样本与标准化样本之间更为相似。为智力功能低下的客户提供服务的临床医生可以有效地基于因素进行测验解释，但使用简式量表可能存在风险。
