抑郁症患者计数Stroop的临床研究

Study on the counting stroop task performance in depression patients

目的采用计数Stroop任务研究抑郁症患者对简单数字加工的注意执行功能状态。方法对30例抑郁症患者及30例对照组进行计数Stroop任务操作。比较分析准确率及反应时。结果抑郁症患者对简单数字加工的准确率与正常对照组一样均为100%;抑郁症患者在执行视觉计数Stroop任务时对三种刺激类型的反应时【匹配:(999.28±95.23)ms、中性:(1037.95±100.06)ms、干扰:(1099.98±101.30)ms】均明显长于对照组【匹配:(803.69±48.40)ms、中性:(817.57±56.12)ms、干扰:(896.39±45.19)ms】,差异均有统计学意义(t分别=10.03、10.52、10.06,P均<0.05)。结论抑郁症患者在简单数字加工过程中的注意执行功能下降。

Objective To study the counting stroop task performance in patients of depressive disorder. Methods Thirty patients of depressive disorder and thirty healthy volunteers performed the counting stroop task. The correct rate and reaction time have been used for the statistical analysis. Results The correct rates of both patients and volunteers were 100%. But the reaction time of the depression patients[match： （999.28±95.23）ms, neutral： （1037.95±100.06）ms, interference：（ 1099.98±101.30）ms]was longer than healthy volunteers[match： （803.69±48.40）ms, neutral： （ 817.57 ±56.12 ） ms, interference： （ 896.39±45.19） ms ]. The different data statistics showed distinct significance （t = 10.03,10.52,10.06, P〈0.05）. Conclusions The results show decrease in the function of attention performance in depressive patients.
