精神分裂症患者的Stroop任务特点

Characteristics of Stroop Task in Schizophrenia Patients

目的:探讨精神分裂症患者认知功能Stroop任务的效应特点及其与临床特征之间的相关性。方法:按不同性别随机选取精神分裂症患者84名,进行Stroop任务测试,并作PANSS量表评定。结果:1精神分裂症患者stroop测试3组色卡反应时间的组间比较(H=79.491,P=0.000)及反应错误次数的组间比较(H=93.519,P=0.000),组间差异均具有统计学意义(P<0.05);2精神分裂症患者的年龄与3组色卡的反应时间均存在具有统计学意义的正相关(P<0.05);3PANSS量表中精神病理量表分值与色卡1反应时间的相关(r=0.225,P=0.040)存在统计学意义,愤怒项目分值与色卡2反应时间(r=-0.226,P=0.039)、色卡3反应错误次数(r=-0.251,P=0.021)的相关存在统计学意义(P<0.05)。结论:精神分裂症患者Stroop任务的效应特点及其与年龄的关系符合人类认知一般规律,Stroop效应基本不受起病年龄及病程影响,但可能与精神病理中的情绪状态有关。

Objective：To explore the characteristics of Stroop task in schizophrenia patients and their relationship with the clinical features.Methods：A total of 84 schizophrenia patients with different gender were selected randomly to take Stroop task,and assessed with PANSS.Results：①The difference between three kinds of Stroop cards in reaction time（ H=79.491,P=0.000） and reaction errors（ H=93.519,P=0 .000 ） had statistical significance;②The positive correlation between age of patients and reaction time of Stroop cards had significant statistical meaning（ P〈0.05）;③The correlations between psychopathology scale score and reaction time of Stroop card1（r=0.225,P=0.040）,item anger score and reaction time of Stroop card2（r=-0.226,P=0.039）,reaction errors of Stroop card3（r=-0.251,P=0.021）were statistically significant.Conclusion：The correlation between Stroop effect and age of schizophrenia patients accords with characteristic of human cognition;Stroop effect isn＇t affected by age of onset and course of disease,but may be influenced by emotional states of schizophrenia patients.
