Patients with schizophrenia have long been observed to perform poorly on the Wisconsin Card Sorting Test (WCST). Although numerous studies have established links between WCST performance and specific and diffuse structural brain abnormalities, little is known about its relationship to occupational functioning. The present study has investigated the relationship between behavior at a vocational work placement and performance on the WCST test for 89 subjects with schizophrenia or schizoaffective disorder. Multiple regression analyses that examined select WCST raw scores and that covaried out IQ and Digit Symbol Subtest scores found that Task Orientation at work was significantly related to WCST Trials to the First Category and Total Number Correct. Multiple regression analyses that examined standard scores, corrected for age and education, revealed that Task Orientation was related to Percent Conceptual Level and that Social Skills were related to Total Errors and Percent Conceptual Level. Results support the criterion-related validity of the WCST and have implications for understanding impairments in work function.
长期以来，人们观察到精神分裂症患者在威斯康星卡片分类测验（WCST）中的表现较差。尽管众多研究已确定WCST表现与特定及弥漫性脑结构异常之间存在关联，但对于其与职业功能的关系却知之甚少。本研究调查了89名精神分裂症或分裂情感性障碍患者在职业工作实习中的行为与WCST测试表现之间的关系。多元回归分析检验了选定的WCST原始分数，并排除了智商和数字符号分测验分数的影响，结果发现工作中的任务导向与WCST达到第一类别的试验次数和正确总数显著相关。多元回归分析检验了经年龄和教育校正后的标准分数，结果显示任务导向与概念水平百分比相关，社交技能与总错误数和概念水平百分比相关。研究结果支持了WCST的标准关联效度，并对理解工作功能障碍具有启示意义。
