疼痛自我效能在冠心病心绞痛患者生命意义感与生活质量间的中介效应

Mediating effect of pain self-efficacy between meaning in life and quality of life in patients with angina pectoris of coronary heart disease

目的探讨冠心病心绞痛患者生命意义感、疼痛自我效能与生活质量的相关性,以及疼痛自我效能在生命意义感与生活质量间的中介作用。方法选取2023年3-9月川北医学院附属医院心血管内科381例因冠心病心绞痛住院的患者作为研究对象。采用一般人口学调查问卷、疾病信息调查问卷、中国心血管病人生活质量评定问卷(CQQC)、疼痛自我效能问卷(PSEQ)、中文版生命意义感量表(C-MLQ)对所有研究对象进行调查,采用Pearson相关分析冠心病心绞痛患者C-MLQ得分、PSEQ得分、CQQC得分的相关性,运用结构方程模型深入剖析疼痛自我效能在生命意义感与生活质量间的中介效应。结果Pearson相关分析结果显示,冠心病心绞痛患者CQQC得分与C-MLQ得分呈正相关(r=0.172,P<0.01);CQQC得分与PSEQ得分呈正相关(r=0.531,P<0.01);C-MLQ得分与PSEQ得分呈现正相关(r=0.147,P<0.01)。生命意义感通过疼痛自我效能对生活质量总作用值为0.319,间接作用值为0.145,占总效应的45.47%。结论冠心病心绞痛患者疼痛自我效能在生命意义感和生活质量之间起到部分中介作用。提高生命意义感有利于提升冠心病心绞痛患者疼痛自我效能,改善其生活质量。

Objective To explore the correlation between meaning in life,pain self-efficacy and quality of life in patients with angina pectoris of coronary heart disease and the mediating effect of pain self-efficacy between meaning in life and quality of life.Methods A total of 381 hospitalized patients with angina pectoris of coronary heart disease in the Department of Cardiology of Affiliated Hospital of North Sichuan Medical College from March to September 2023 were selected as the research objects.The General Demographic Questionnaire,Disease Information Questionnaire,Chinese Cardiovascular Quality of Life Questionnaire(CQQC),Pain Self-Efficacy Questionnaire(PSEQ)and Chinese version of Meaning in Life Questionnaire(C-MLQ)were used to investigate all subjects.Pearson correlation was used to analyze the correlation between C-MLQ score,PSEQ score and CQQC score in patients with angina pectoris of coronary heart disease.Structural equation model was used to analyze the mediating effect of pain self-efficacy between meaning in life and quality of life.Results Pearson correlation analysis showed that the CQQC score was positively correlated with C-MLQ score in patients with angina pectoris(r=0.172,P<0.01).The scores of CQQC and PSEQ were positively correlated(r=0.531,P<0.01).The C-MLQ score was positively correlated with the PSEQ score(r=0.147,P<0.01).The total effect value of meaning in life on quality of life through pain self-efficacy was 0.319,and the indirect effect value was 0.145,accounting for 45.47%of the total effect.Conclusion Pain self-efficacy plays a partial mediating role between meaning in life and quality of life in patients with angina pectoris of coronary heart disease.Improving the sense of meaning in life is conducive to improving the pain self-efficacy level of patients with angina pectoris and improving their quality of life.
