The latent factor structure of the German Wechsler Intelligence Scale for Children-Fifth edition (German WISC-V) was examined using complementary hierarchical exploratory factor analyses (EFAs) with Schmid and Leiman transformation and confirmatory factor analyses (CFAs) for all reported models from the German WISC-V and rival bifactor models using the standardization sample ( = 1,087) correlation matrix of the 15 primary and secondary subtests. EFA results did not support a fifth factor (Fluid Reasoning). A four-factor model with the dominant general intelligence () factor resembling the WISC-IV was supported by EFA. CFA results indicated the best representation was a bifactor model with four group factors, complementing EFA results. Present EFA and CFA results replicated other independent assessments of standardization and clinical samples of the United States and international versions of the WISC-V and indicated primary, if not exclusive, interpretation of the Full Scale IQ as an estimate of .
采用互补的层次探索性因素分析（EFA）和 Schmid 和 Leiman 转换，对德国韦氏儿童智力量表第五版（德语 WISC-V）的潜在因素结构进行了检验，并对德语 WISC-V 报告的所有模型和竞争的双因素模型进行了验证性因素分析（CFA），使用的是标准化样本（=1087）的 15 个主要和次要子测验的相关矩阵。EFA 结果不支持第五个因素（流体推理）。EFA 支持具有主导一般智力（）因素的四因素模型，类似于 WISC-IV。CFA 结果表明，最好的表示是一个具有四个组因素的双因素模型，补充了 EFA 的结果。目前的 EFA 和 CFA 结果复制了其他关于 WISC-V 标准化和临床样本的独立评估，以及美国和国际版本的结果，表明主要的（如果不是唯一的）全量表智商的解释是作为的估计。
