Abstract:
Objective:To explore the mediating effect of negative cognitive processing bias between type D personality and depression after percutaneous coronary intervention (PCI) .Methods:Using the convenient sampling method, a total of 340 patients who underwent PCI for the first time in Department of Cardiology in the Second Affiliated Hospital of Harbin Medical University from September to December 2021 were selected as the research objects. The General Demographic Data Questionnaire, Type D Personality Scale (DS14), Negative Cognitive Processing Bias Questionnaire (NCPBQ) and Beck Depression Inventory-Ⅱ (BDI-Ⅱ) were used to investigate. Spearman correlation analysis was used to determine the correlation between type D personality, negative cognitive processing bias and depression. The mediating effect model was established by AMOS 24.0 software to analyze the mediating effect of negative cognitive processing bias between type D personality and depression.Results:A total of 340 questionnaires were sent out in this study, and 317 valid questionnaires were recovered, with an effective questionnaire recovery rate of 93.2%. The total score of Type D Personality Scale of 317 patients after PCI was (18.05±4.15), in which the score of negative affectivity dimension was (9.51±2.33) and the score of social inhibition dimension was (8.54±2.61). The proportion of patients with type D personality is 24.9% (79/317). The score of Beck Depression Inventory-Ⅱ (BDI-Ⅱ) was (9.52±4.83), and the incidence of depression was 20.2% (64/317). Correlation analysis showed that D-type personality of patients, negative cognitive processing bias and depression were positively correlated ( P<0.05). The mediating effect analysis showed that type D personality could directly affect the occurrence of depression (effect size 0.431, P<0.001), or indirectly through negative cognitive processing bias (effect size 0.145, P<0.001) . Conclusions:The negative cognitive processing bias is an important factor in the occurrence of depression in patients with CHD and with type D personality. Improving the negative cognitive processing bias will help reduce the occurrence of depression and improve the prognosis.
