A newly developed T score conversion system that corrects Wechsler Adult Intelligence Scale (WAIS) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest and IQ scores for appropriate demographic variables was used to compare subjects' performance on the two versions of the instrument. Using 428 pairs of subjects matched on age, education, and sex, with one person in each pair having taken the WAIS and the other the WAIS-R, we found no significant differences in level or pattern of performance when analyses were performed on the T scores. This was in contrast to highly significant differences when uncorrected scaled scores and IQ values were compared. Therefore, the T score system appears to provide a tool which may help clinicians make more direct comparisons between the results obtained on the WAIS and WAIS-R.
一种新开发的T分数转换系统，该系统针对适当的人口统计学变量对韦氏成人智力量表（WAIS）和韦氏成人智力量表修订版（WAIS-R）的子测验分数和智商分数进行校正，用于比较受试者在这两个版本测验上的表现。我们选取了428对在年龄、教育程度和性别上匹配的受试者，每对中的一人进行了WAIS测验，另一人进行了WAIS-R测验，当对T分数进行分析时，我们发现表现水平或模式没有显著差异。这与比较未校正的量表分数和智商值时的高度显著差异形成对比。因此，T分数系统似乎提供了一种工具，可帮助临床医生更直接地比较WAIS和WAIS-R所获得的结果。
