This study investigated the factor structure of the French Wechsler Intelligence Scale for Children–Fifth Edition with five standardization sample age groups (6-7, 8-9, 10-11, 12-13, 14-16 years) using hierarchical exploratory factor analysis followed by Schmid–Leiman procedure. The primary research questions included (a) how many French Wechsler Intelligence Scale for Children–Fifth Edition factors should be extracted and retained in each age subgroup, (b) how are subtests associated with the latent factors, (c) was there evidence for the publisher’s claim of five first-order factors and separate Visual Spatial and Fluid Reasoning factors, (d) what proportion of variance was due to general intelligence versus the first-order group ability factors following a Schmid–Leiman procedure, and (e) do results support the age differentiation hypothesis? Results suggested that four factors might be sufficient for all five age groups and results did not support the distinction between Visual Spatial and Fluid Reasoning factors. While the general factor accounted for the largest portions of variance, the four first-order factors accounted for small unique portions of variance. Results did not support the age differentiation hypothesis because the number of factors remained the same across age groups, and there was no change in the percentage of variance accounted for by the general factor across age groups.

五个年龄组的法国 WISC-V (WISC-VFR) 探索性因素分析:基于标准化样本的分析

本研究采用分层探索性因子分析,调查了法国韦氏儿童智力量表第五版的因子结构,其中包含五个标准化样本年龄组(6-7、8-9、10-11、12-13、14-16 岁)其次是施密德-莱曼程序。主要研究问题包括(a)每个年龄亚组应提取和保留多少法国韦氏儿童智力量表第五版因素,(b)子测试如何与潜在因素相关联,(c)是否有证据表明出版商声称五个一阶因素和单独的视觉空间和流体推理因素,(d)根据施密德-莱曼程序,一般智力与一阶群体能力因素的方差比例是多少,(e) 结果是否支持年龄分化假说?结果表明,四个因素可能对所有五个年龄组都足够,结果不支持视觉空间和流体推理因素之间的区别。虽然一般因素占方差的最大部分,但四个一阶因素占方差的小独特部分。结果不支持年龄分化假设,因为不同年龄组的因素数量保持不变,并且不同年龄组的一般因素占方差的百分比没有变化。虽然一般因素占方差的最大部分,但四个一阶因素占方差的小独特部分。结果不支持年龄分化假设,因为不同年龄组的因素数量保持不变,并且不同年龄组的一般因素占方差的百分比没有变化。虽然一般因素占方差的最大部分,但四个一阶因素占方差的小独特部分。结果不支持年龄分化假设,因为不同年龄组的因素数量保持不变,并且不同年龄组的一般因素占方差的百分比没有变化。
