A factor analysis was conducted on the Carrow Auditory-Visual Abilities Test for the purpose of identifying common factors measured by the test. Two sets of scores were used, one from a normal population of 1,032 children and one from a clinical population of 141 children. Two basic factors accounted for a good portion of the total variance. The subtests that loaded on Factor 1 were Visual Discrimination Matching, Visual Discrimination Memory, Visual Motor Copying, Visual Motor Memory, Motor Speed Accuracy, Picture Memory, and Auditory Blending. The subtests that loaded on Factor 2 were Picture Sequence Selection; Digits Forward; Sentence Repetition; Word Repetition 1, 2, 3; and Total. Subtests that did not fall clearly into either factor were Digits Backward and the two Auditory Discrimination subtests. Except for the Auditory Discrimination subtests, there were no essential differences in the factor matrix between normal and clinical populations.
为了确定卡罗视听能力测试所测量的共同因素，进行了一项因素分析。使用了两组分数，一组来自1032名儿童的正常群体，另一组来自141名儿童的临床群体。两个基本因素占总方差的很大一部分。在因素1上有载荷的子测试包括视觉辨别匹配、视觉辨别记忆、视觉运动抄写、视觉运动记忆、运动速度准确性、图片记忆和听觉混合。在因素2上有载荷的子测试包括图片序列选择、顺背数字、句子复述、单词复述1、2、3以及总分。没有明显归入任一因素的子测试是倒背数字和两个听觉辨别子测试。除了听觉辨别子测试外，正常群体和临床群体之间的因素矩阵没有本质差异。
