本研究的目的是探讨威斯康星卡片分类测验（WCST）的因子结构，并确定精神分裂症的缺陷维度。对精神分裂症及精神分裂症相关精神病患者（n = 292）、精神分裂症患者一级亲属（n = 91）和正常对照（n = 141）的WCST评分进行主因子分析，然后进行正交旋转。这导致了3个因素，毅力，未能保持设置，和特殊的排序。检测到的因子结构在精神分裂症和控制子样本中是不变的。此外，它还从两个较小的样本中复制了先前的发现。只有坚持不懈和（在较小程度上）特殊分类似乎能将精神分裂症患者与比较者区分开来。只有毅力具有良好的敏感性和特异性。以及与智商、注意力和其他执行功能评估指标之间最显著的相关性。因此，持续性似乎是精神分裂症最有诊断价值和最典型的WCST特征。
The aim of this study was to explore the factorial structure of the Wisconsin Card Sorting Test (WCST) and to identify the dimensions of deficit in schizophrenia. WCST scores in patients with schizophrenia and schizophrenia-related psychosis (n = 292), Ist degree relatives of schizophrenic patients (n = 91), and normal controls (n = 141) were subjected to a principal factor analysis followed by orthogonal rotation. This led to 3 factors, perseveration, failure to maintain set, and idiosyncratic sorting. The detected factor structure was found to be invariant across the schizophrenic and control subsamples. Moreover, it replicated previous findings from 2 smaller samples. Only perseverations and, to a lesser degree, idiosyncratic sorting appeared to differentiate schizophrenic patients from comparisons. Only perseveration had good sensitivity and specificity. as well as the most robust significant correlations with estimates of IQ, attention, and other measures of executive functioning. Thus, perseveration appears to be the most diagnostically useful and characteristic WCST feature of schizophrenia.
