知觉压力在冠心病经皮冠状动脉介入治疗后患者健康素养与心脏康复意愿间的中介效应

Mediating effect of perceived stress on health literacy and cardiac rehabilitation intention in patients with coronary heart disease after percutaneous coronary intervention

目的探讨知觉压力在冠心病经皮冠状动脉介入治疗后患者健康素养与心脏康复意愿间的中介作用。方法采用便利抽样法,选取2023年2-7月在嘉兴市第二医院心内科行经皮冠状动脉介入治疗的患者(n=387)为研究对象。采用一般资料调查表、心脏康复意愿量表、健康素养量表、中文版知觉压力量表对患者进行调查。采用Pearson相关分析法分析患者知觉压力、健康素养及心脏康复意愿间的相关性,应用Amos 22.0建立结构方程模型,并采用Bootstrap法检验知觉压力的中介效应。结果冠心病经皮冠状动脉介入治疗后患者心脏康复意愿得分为(37.56±5.25)分,健康素养得分为(88.10±6.59)分,知觉压力得分为(29.64±4.98)分。健康素养与心脏康复意愿呈正相关(r=0.394,P<0.01),知觉压力与健康素养(r=-0.388,P<0.01)、心脏康复意愿(r=-0.451,P<0.01)呈负相关。知觉压力在健康素养与心脏康复意愿间的间接效应值为0.235,占总效应的34.21%。结论知觉压力在冠心病经皮冠状动脉介入治疗后患者健康素养与心脏康复意愿间起到部分中介作用。

Objective To explore the mediating effect of perceived stress on health literacy and cardiac rehabilitation intention in patients with coronary heart disease after percutaneous coronary intervention(PCI).Methods Convenience sampling method was used to select the patients(n=387)who underwent PCI in the cardiology department of Jiaxing Second Hospital from February to July 2023 as the study objects.General data questionnaire,Chinese Perceived Stress Scale(CPSS),Health Literacy Management Scale(He LMS),Cardiac Rehabilitation Inventory(CRI)were used to investigate the patients.Pearson correlation analysis was used to analyze the correlations among perceived stress,health literacy and cardiac rehabilitation intention of patients.Amos 22.0 was applied to establish a structural equation model,and Bootstrap method was used to test the mediating effect.Results The scores of CRI,He LMS and CPSS were(37.56±5.25),(88.10±6.59)and(29.64±4.98)in patients with coronary heart disease after PCI.Health literacy was positively correlated with cardiac rehabilitation intention(r=0.394,P<0.01),while perceived stress was negatively correlated with health literacy(r=-0.388,P<0.01)and cardiac rehabilitation intention(r=-0.451,P<0.01).The indirect effect of perceived stress on health literacy and cardiac rehabilitation intention was 0.235,accounting for 34.21%of the total effect.Conclusion Perceived stress plays a partial mediating role between health literacy and cardiac rehabilitation intention of patients with coronary heart disease after PCI.
