Factor-based Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) tetrads were investigated using the Taiwan WAIS-IV standardization sample of 1,105 normal adults aged between 16 and 90 years. Various psychometric characteristics, time constraints, and qualities of estimation were compared among 90 tetrads using linear equation procedures. Among the tetrads, the Information-Visual Puzzle-Digit Span-Digit Symbol combination had higher performance than the other combinations with respect to overall estimation quality and time saved. Moreover, the Similarities-Visual Puzzle-Digit Span-Digit Symbol, Information-Matrix Reasoning-Digit Span-Digit Symbol, and Information-Visual Puzzle-Letter Number Sequencing-Digit Symbol combinations obtained the most efficient estimates. For clinicians who value the utility of Block Design, the Information-Block Design-Digit Span-Digit Symbol combination was found to provide high estimation quality. The findings also revealed that the previously recommended Wechsler Adult Intelligence Scale-Third Edition tetrads are no longer the best solutions for the WAIS-IV. Furthermore, even the selected WAIS-IV tetrads had substantial misclassification rates; the four-factor short forms tend to underestimate the full-scaled IQ for highly intelligent adults. Therefore, these short forms should be used cautiously and for screening purposes only.
使用台湾韦氏成人智力量表第四版（WAIS-IV）对1105名年龄在16至90岁之间的正常成年人标准化样本进行基于因素的四分体研究。使用线性方程程序比较了90个四分体在各种心理测量特征、时间限制和估计质量方面的差异。在这些四分体中，信息-视觉拼图-数字广度-数字符号组合在整体估计质量和节省时间方面比其他组合表现更好。此外，相似性-视觉拼图-数字广度-数字符号、信息-矩阵推理-数字广度-数字符号以及信息-视觉拼图-字母数字排序-数字符号组合获得了最有效的估计。对于重视积木设计效用的临床医生来说，信息-积木设计-数字广度-数字符号组合被发现具有较高的估计质量。研究结果还表明，先前推荐的韦氏成人智力量表第三版四分体不再是WAIS-IV的最佳解决方案。此外，即使是选定的WAIS-IV四分体也有相当高的错误分类率；四因素简式往往会低估高智商成年人的全量表智商。因此，这些简式应谨慎使用，仅用于筛查目的。
