本研究首次对威斯康星卡片分类测验（WCST）进行了大规模验证性因素分析。结果总体上支持探索性因素分析文献中所报告的三因素解决方案。然而，只有反映一般执行功能的第一个因素在统计学上是可靠的。次要因素虽然可能反映有意义的认知能力，但不太稳定，除非所有受试者都完成全部128张卡片。WCST有两种终止规则可能是导致文献中所报告的因素分析解决方案各异的原因，而且过早终止可能会导致一些有用信息的丢失。有必要继续进行多变量研究，以更好地阐明WCST表现背后的过程以及它们之间的相互关系。（c）2004年美国神经心理学学会。由爱思唯尔有限公司出版。保留所有权利。
The present study represents the first large scale confirmatory factor analysis of the Wisconsin Card Sorting Test (WCST). The results generally support the three factor solutions reported in the exploratory factor analysis literature. However, only the first factor, which reflects general executive functioning, is statistically sound. The secondary factors, while likely reflecting meaningful cognitive abilities, are less stable except when all subjects complete all 128 cards. It is likely that having two discontinuation rules for the WCST has contributed to the varied factor analytic solutions reported in the literature and early discontinuation may result in some loss of useful information. Continued multivariate research will be necessary to better clarify the processes underlying WCST performance and their relationships to one another. (c) 2004 National Academy of Neuropsychology.
