Abstract

A 7-subtest short form of the Wechsler Adult Intelligence Scale-III (WAIS-III) previously demonstrated good comparability in estimating Full Scale and Verbal IQ summary scores, with adequate comparability in estimating Performance IQ. In a mixed clinical sample of 295 patients, the current study assessed the equivalence of the index scores generated from the full and prorated WAIS-III. The results revealed correlations corrected for redundancy of .90, .86, .87, and .75 for the Verbal Comprehension (VCI), Perceptual Organization (POI), Working Memory (WMI), and Processing Speed (PSI) indexes, respectively. Although the 7-subtest short form of the WAIS-III was not designed to estimate index scores, adequate estimates are viable for VCI, POI, and WMI when the goal is to obtain group, rather than individual, data points.

摘要

韦氏成人智力量表第三版（WAIS - III）的一个由7个分测验组成的简版，先前已证明在估计全量表智商和言语智商汇总分数方面具有良好的可比性，在估计操作智商方面也具有足够的可比性。在一个由295名患者组成的混合临床样本中，本研究评估了完整版和简略版WAIS - III所产生的指数分数的等效性。结果显示，言语理解（VCI）、知觉组织（POI）、工作记忆（WMI）和加工速度（PSI）指数经冗余校正后的相关性分别为0.90、0.86、0.87和0.75。尽管WAIS - III的7个分测验简版并非旨在估计指数分数，但当目标是获取组数据点而非个体数据点时，对于VCI、POI和WMI而言，进行充分的估计是可行的。
