冠心病伴发抑郁者记忆偏向的研究

Study of memory bias in coronary heart disease with depressive mood

目的探讨冠心病伴发抑郁者记忆偏向的特点。方法对冠心病患者用Beck抑郁问卷、SDS抑郁自评量表筛选出单纯冠心病组、冠心病伴发抑郁情绪组(轻度抑郁16例、中度9例、重度5例)各30例,参加自传体记忆测验。结果 (1)冠心病伴发抑郁情绪组总的概括性记忆得分,对不同词性线索词的均显著高于单纯冠心病组(P<0.01);(2)单纯冠心病组对消极词概括性记忆得分显著高于积极词(P<0.01),而冠心病伴发抑郁情绪组则差异无统计学意义(P>0.05);(3)不同抑郁程度者的自传体记忆概括性得分差异有统计学意义(P<0.01),表现为得分随抑郁程度的加深而增高。结论冠心病伴发抑郁个体的自传体记忆概括性存在过度概括化的缺陷;其自传体记忆的概括性水平与伴发抑郁情绪的严重程度有关。

Objective To explore the memory bias in coronary heart disease with depressive mood. Methods The coronary heart disease （CHD）inpatients were surveyed by Beck Depression Inventory（BDI）and Self-Rating Depression Scale（SDS）. And 60 inpatients were chosen for further experiment：30 with depressive mood（16 mild,9 moderate and 5 severe）and 30 normal ones. Then they were measured with the Autobiographical Memory test. Results （1）The generalized scores of the CHD inpatients with depressive mood group were higher than those of the simple CHD in total memorizing cue words,positive and negative cues word,and there showed significant statistical difference（P 〈 0.01）. （2）In the simple CHD group,the scores in positive cue words were significantly lower than those in negative cue words （P 〈 0.01 ） ;but the CHD inpatients with depressive mood group had no significantly different（P 〉 0.05 ） ;（3）The scores of the CHD inpatients with different depressive moods had significant differences（P 〈 0.01）,expressed as：with the deepening of the severity of depression,the scores of generalized autobiographical memories higher. Conclusion The autobiographical memory of CHD inpatients with depressive mood has deficits,which is mainly manifested as overgenerality. And the generality of autobiographical memory is associated with the severity of depressive moods.
