Exploratory factor analyses were conducted separately on the Wechsler Abbreviated Scale of Intelligence (WASI; The Psychological Corporation, 1999) adult standardization sample (n = 1,145) and a diagnostically heterogeneous adult clinical sample (n = 201). In the latter group, means for age, education, and WASI Full Scale IQ were 59.25 years (SD = 17.52), 12.39 years (SD = 2.88), and 89.91 (SD = 16.00). For each sample, the four WASI subtests were subjected to a principal-axis factor analysis followed by varimax and promax rotations. Two factors were specified to be retained. Verbal Comprehension and Perceptual Organization factors were identified in both analyses. Coefficients of congruence were 0.98 for Factor I and 0.99 for Factor II, suggesting factorial equivalence across the standardization and clinical samples.
对韦氏成人智力量表简版（WASI；心理公司，1999年）的成人标准化样本（n = 1145）和诊断结果各异的成人临床样本（n = 201）分别进行了探索性因素分析。在后一组中，年龄、受教育程度和WASI全量表智商的均值分别为59.25岁（标准差 = 17.52）、12.39年（标准差 = 2.88）和89.91（标准差 = 16.00）。对每个样本，对WASI的四个子测验进行主成分因素分析，随后进行方差最大化和斜交旋转。指定保留两个因素。在两次分析中均识别出言语理解和知觉组织因素。因素I的一致性系数为0.98，因素II的一致性系数为0.99，表明标准化样本和临床样本之间存在因素等效性。
