韦氏儿童智力量表中国修订本(WISC-CR)的因素分析

FACTOR ANALYSIS OF THE WECHSLER INTELLIGENCE SCALE FOR CHILDREN-CHINESE REVISION(WISC-CR)

本研究用主成分分析和α因素分析两种方法对韦氏儿童智力量表中国修订本(WISC-CR)以及原量表WISC-R常模进行因素分析,并采用斜交旋转对初始因子矩阵进行转轴处理。结果表明:三因子模型比较符合WISC-CR的结构。常识、类同、词汇和理解四个分测验主要负荷言语理解因子;填图、图片排列、积木、拼图和迷津五个分测验主负荷知觉组织因子;而算术、背数和译码三个分测验主要负荷记忆/不分心因子。WISC-CR与WISC-R各分测验所负荷的各种因子一致性。83-.971,说明WISC-CR保持了原量表的功能,具有较好的结构效度。

The Wechsler Intelligence Scale for Children--Chinese Revisiot(WISC-CR) was analyzed using principal-component analysis and alphafactor analysis followed by oblique rotations of two and three factors.Three meaningful factors were present for each age group. The VerbalComprehension factor consisted of Information, Similarities, Vocabulary,and Comprehension, while the perceptural organization factor was com-posed of picture Completion, picture Arrangement, Block Design, ObjectAssembly and Maze. The Memory/Freedom from Distractibility factor hadmajor loading on Arithmatic, Digit Span, and Coding. Factor structureof the WISC-CR and WISC-R were very similar. The coefficiets of corre-lation between the WISC-CR and WlSC-R factors were high, the VerbalComprehension factor correlated .971, Percepture Organization factor co-rrelated .969, and the Memory/Freedom from Distractibility factor corr-elated .832.
