目的:探索高强迫特质大学生的执行功能特征及其对高强迫特质大学生的鉴别作用。方法:纳入90名高强迫特质大学生[强迫问卷修订版(OCI-R)得分≥36分]和90名低强迫特质大学生(OCI-R得分≤22分),完成执行功能问卷(DEX)和贝克抑郁问卷(BDI)。采用工作特征曲线分析考察执行功能对高强迫特质大学生的鉴别作用。结果:高强迫特质大学生的DEX总分和各分量表得分均高于低强迫特质大学生(均P<0.001);OCI-R得分和DEX得分呈正相关(r=0.52,P<0.001);DEX的工作特质曲线下面积(AUC)为0.84。当DEX总分为23.5分(灵敏度84.4%,特异度59%)～26.5分(灵敏度78.9%,特异度70.9%)时,对高强迫特质大学生有良好的鉴别作用。结论:高强迫特质大学生可能存在较多执行功能异常行为,执行功能指标有助于识别高强迫特质。

To examine the executive function characteristics in college students with high obsessive compulsive traits and the identifying function of execution function characteristics to distinguish college students with high obsessive-compulsive traits from college students with low obsessive-compulsive traits. Methods: Ninetycollege students with high obsessive-compulsive traits and 90 college students with low obsessive compulsive traits were assessed with the Obsessive-Compulsive Inventory-Ｒevised ( OCI-Ｒ) ，Dysexecutive Questionnaire ( DEX) ，and Beck Depression Inventory ( BDI) . The receiver operating characteristic ( ＲOC) analysis was used to evaluate the prediction effect of executive function in college students with high obsessive-compulsive traits. Ｒesults: College students with high obsessive-compulsive traits reported higher total and all subscales scores of the DEX than those with low obsessive-compulsive traits ( Ps ＜ 0. 001) . There was a positive correlation between the OCI-Ｒ score and DEX score ( r = 0. 52，P ＜ 0. 001) . The mean area under the curve ( AUC) of the DEX was 0. 84. When the total score of DEX was 23. 5 ( sensitivity 84. 4%，specificity 59%) to 26. 5 ( sensitivity 78. 9%，specificity 70. 9%) ，it had a good discriminative effect on college students with highobsessive-compulsive traits. Conclusion: It suggests that college students with high obsessive-compulsive trait may have more dysexecutive functions，and the use of the DEX maybe helpful to identify high obsessive-compulsive trait.
