不同程度述情障碍者威斯康星卡片分类测验的比较研究

目的：探讨高述情障碍者有无认知功能的受损及其特征方法：采用多伦多述情障碍量表中文版（TAS-20-C）对6126名在校大学生的述情障碍情况进行评定，以该量表得分值为标准，从最高分降序选取150名大学生作为述情障碍高分组，从最低分升序选取150名大学生作为述情障碍低分组，两组均接受威斯康星卡片分类测验（WCST）。结果：述情障碍高分组的总测验数、持续应答数、持续性错误应答数、完成第一次分类应答数、不能维持定势的次数均高于低分组（P〈0．05）；而高分组的正确应答数、完成分类数、概念化水平应答率则明显低于低分组（P〈0．05）；TAS-20-C的总分及因子分与WCST成绩呈显著相关。结论：述情障碍的高低与额叶功能受损的程度有关。

A Comparative Study of Wisconsin Card Sorting Test in Individuals with Different Degrees of Alexithymia

Objective: To explore the cognitive function of individuals with different degrees of alexithymia.Methods: 6126 university students were administered TAS-20-C.According to the TAS-20-C scores,a high alexithymia group and a low alexithymia group were selected.Both groups consist of 150 students and WCST was used to investigate the executive function of the two groups.Results: Compared to the high alexithymia group,the low group showed a significantly lower level in the number of response errors,perservation of responses,perservation of errors,random errors,first catalogue responses and the number of failing to keep fixed posture(P<0.05).The low alexithymia group had a significantly higher level in the number of correct responses,the rate of conceptualization responses and correctness.And the relation between TAS-20-C scores and WCST performance is significantly negative(P<0.05).Conclusion: The level of alexithymia was strongly correlated with the level of impairment of cognitive function.
