摘要:

目的:探索不同抑郁程度个体注意抑制能力的特点。方法:利用Beck抑郁自评量表、抑郁自评量表(SDS)、汉密顿抑郁量表对所征募的被试进行前后两次测评,时间间隔为两周,最终筛选出77名符合(正常对照组、抑郁症状组和抑郁症患者组)三组入组标准的被试,均采用Stroop色词干扰测试、威斯康星卡片分类测试,数据用SPSS18.0软件进行t检验和方差分析。结果:1) 在Stroop色词干扰测试错误率方面,抑郁症患者组阈上、阈下错误率显著高于正常对照组和抑郁症状组(t = 2.17, P = 0.038),且该组阈下错误率高于阈上错误率。2) 在Stroop色词干扰测试反应时方面,三组间阈上、阈下反应时呈现显著差异(P < 0.05),且随着抑郁程度的加重,反应时显著延长;其中抑郁症患者组阈上反应时长于阈下反应时。3) 在威斯康星卡片分类测试中,抑郁症患者组成绩显著低于正常对照组和抑郁症状组(P < 0.05),其他组别间差异不显著(P > 0.05)。测试中非持续性错误这一项指标,症状组和患者组数值均偏离正常值(≥24),且患者组分值较高,提示处于抑郁状(病)态的个体出现注意抑制能力损害。结论:个体注意抑制能力高低与抑郁严重程度呈反比。

Objective: To explore the characteristics of attention inhibition ability in individuals with different degrees of depression. Method: A total of 77 subjects were involved. They were assessed twice by Beck Depression Inventory (BDI), Self-rating Depression Scale (SDS), Hamilton Depression Rating scale (HAMD) with intervals of two weeks. All of them were divided into three groups, including normal group, depressive symptoms group and depression group. The attention inhibition of ex-ecutive function was measured in Stroop Color-Word Test and Wisconsin Card Sorting Test (WCST). The data were analyzed by SPSS18.0 in t-test and ANOVA. Results: 1) In Stroop Color-Word Test, depression group showed the highest error rate among 3 groups (t = 2.17, P = 0.038), and in this group subliminal error rate was higher than suprathreshold error rate. 2) In Stroop Color-Word Test, there were significant differences among the 3 groups on the reaction time both in subliminal and suprathreshold (P < 0.05), and with the aggravation of depressive state, reaction time became longer. In depression group, subliminal reaction time was shorter than suprathreshold reaction time. 3) In Wisconsin Card Sorting Test (WCST), the depression group shows the worst performance (P < 0.05) among 3 groups and there was no significant difference between the other two groups (P > 0.05). On Non-persistence errors (NRPE) of WCST, both depressive symptoms group and depression group got the higher scores. Conclusion: The severity of depressive state is inversely proportional to the attention inhibition ability.
