Study of Memory Bias in Coronary Heart Disease with Depressive Mood

The objective of this paper is to explore the characteristics of the memory bias in Coronary heart disease with Depressive Mood, in which the inpatients with coronary heart disease (CHD) have been surveyed by Self-Rating Depression Scale (SDS) and 60 inpatients were chosen for further experiment: half with depressive mood (16 mild, 9 moderate and 5 severe) and the rest being normal. Then they were measured with the Autobiographical Memory test. The results revealed that ① The generalized scores of the CHD inpatients with depressive mood group were higher than those of the simple CHD in total memorizing clue words, positive and negative clue words, and a significant statistical difference(P<0.01) was shown.② In the simple CHD group, the scores in positive clue words were significantly lower than those in negative clue words (P<0.01);however, the CHD inpatients with depressive mood group had no significant difference (P>0.05) ;③ The scores of the CHD inpatients with different depressive moods had significant differences(P<0.01)，that is: with the worsening of the depression, the scores of generalized autobiographical memories became higher. It can be concluded that the autobiographical memory of CHD inpatients with depressive mood has deficits, which is mainly manifested as over generality, and the generality of autobiographical memory is associated with the severity of depressive moods.
