摘　　要：目的:对负性情绪组和正常对照组被试进行认知执行功能测定,探讨负性情绪患者的认知执行功能特征,为临床诊断治疗提供参考。方法:通过贝克抑郁量表和贝克焦虑量表测查被试的抑郁和焦虑程度,并运用认知调控测试、Stroop测试和语词流畅性测试研究所有被试的认知执行功能,比较高负性情绪组和低负性情绪组的认知执行功能特征。结果:(1)低负性情绪组比高负性情绪组在完成AST测验大多数任务操作上速度更快(P<0.05),错误数更少,且抑郁情绪症状和焦虑情绪症状与完成AST测验所需时间的相关性分别在0.01和0.05的水平上显著;(2)低抑郁组比高抑郁组在完成Stroop任务操作上速度更快(P<0.01),且难度越大,低负性情绪组与高负性情绪组的成绩差异越明显;(3)低负性情绪组与高负性情绪组在完成VF测验中,除了低焦虑组在正确率指标上不如高焦虑组外,其他成绩都优于高负性情绪组。结论:高负性情绪者的认知执行功能受到不同程度的损伤,任务难度越大,其认知执行功能受损表现越明显。Objective： To study the differences of cognitive executive function between high negative emotion patients and low negative emotion patients, which could provide evidence for clinical diagnosis. Methods： The depression and anxiety levels of 249 subjects were examined by using the Beck Depression Inventory （BDI） and Beck Anxiety Inventory （BAI）, then these subjects were divided into groups as following： high-depression group, low-depression group, high-anxiety group and low-anxiety group. The differences of cognitive executive function between high-negative emotion groups and low-negative emotion groups were analyzed. Results：（1） The speed of low-negative emotion groups was faster and the number of errors was less than high-negative emotion groups （P〈0.05）. And there were correlations between the negative emotion and the required time to complete AST. （2） The speed to complete the Stroop Test of low-depression group was significantly faster than high-depression group （Ptime of CST dot 〈0.01; Ptime of CST word〈0.01）, and the number of errors was less （Perrors of CST dot〈0.05; Perrors ofCST color〈0.01）. And the more difficult the task was, the more obvious the differences were between high-negative emotion groups and low-negative emotion groups. （3） All the indices in VF Test except accuracy rate of low-negative emotion groups were better than the high-negative emotion group. Conclusion： There is cognitive executive dysfimction in patients with high-negative emotion and the dysfunction in depression patients is much severer than that of anxiety patients.
