This investigation assessed the ability of the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) short forms to estimate both index and IQ scores in a large, mixed clinical sample (N = 809). More specifically, a commonly used modification of Ward's seven-subtest short form (SF7-A), a recently proposed index-based SF7-C and eight-subtest short form (SF8) were evaluated. All three SFs proved adequate for estimating verbal comprehension, perceptual organization, and full-scale intelligence within considerably less time relative to an SF11 that provides full measurement of WAIS index scores. The SF7-A provided the best combination overall in terms of psychometric performance and estimated time savings. However, SF8 best represents all four factors and allows measurement of processing speed. The SF7-C was most hampered by inclusion of the Block Design subtest in the current assessment, but may prove advantageous in future extensions to the WAIS-IV.
本研究评估了韦氏成人智力量表第三版（WAIS-III）短式测验在一个大型混合临床样本（N=809）中估计指标和智商分数的能力。更具体地说，评估了 Ward 的七测验短式测验（SF7-A）的一种常用修正版、最近提出的基于指标的 SF7-C 和八测验短式测验（SF8）。与提供 WAIS 指标分数完整测量的 SF11 相比，所有三种 SF 都可以在相对较短的时间内充分估计言语理解、知觉组织和全量表智商。SF7-A 在心理测量性能和估计节省时间方面提供了最佳的综合表现。然而，SF8 最好地代表了所有四个因素，并允许测量加工速度。SF7-C 受到当前评估中包含的积木设计测验的最大阻碍，但在未来的 WAIS-IV 扩展中可能会证明是有利的。
