The factor structure of the 16 Primary and Secondary subtests of the Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V; Wechsler, 2014a) standardization sample was examined with exploratory factor analytic methods (EFA) not included in the WISC-V Technical and Interpretive Manual (Wechsler, 2014b). Factor extraction criteria suggested 1 to 4 factors and results favored 4 first-order factors. When this structure was transformed with the Schmid and Leiman (1957) orthogonalization procedure, the hierarchical g-factor accounted for large portions of total and common variance while the 4 first-order factors accounted for small portions of total and common variance; rendering interpretation at the factor index level less appropriate. Although the publisher favored a 5-factor model where the Perceptual Reasoning factor was split into separate Visual Spatial and Fluid Reasoning dimensions, no evidence for 5 factors was found. It was concluded that the WISC-V provides strong measurement of general intelligence and clinical interpretation should be primarily, if not exclusively, at that level. (PsycINFO Database Record
采用韦氏儿童智力量表第五版（WISC-V；韦氏，2014a）标准化样本中的16个主要和次要分测验的因素结构，运用WISC-V技术与解释手册（韦氏，2014b）未包含的探索性因素分析方法（EFA）进行检验。因素提取标准提示为1至4个因素，结果支持4个一阶因素。当采用施密德和莱曼（1957）的正交化程序对该结构进行转换时，层次g因素占总方差和共同方差的大部分，而4个一阶因素占总方差和共同方差的小部分；这使得在因素指数水平上的解释不太合适。尽管出版商倾向于一个五因素模型，即将知觉推理因素分为单独的视觉空间和流体推理维度，但未发现支持5个因素的证据。研究得出结论，WISC-V对一般智力有很强的测量作用，临床解释即使不是完全也应主要在该水平进行。（PsycINFO数据库记录）
