目的 基于结构方程模型探究冠状动脉硬化性心脏病（简称冠心病）患者戒烟动机的影响因素，为制订有效干预措施提供理论参考。 方法 2021年7-12月，采用便利抽样法选择杭州市3所医院门诊就诊的464例冠心病患者为研究对象，采用一般资料问卷、领悟社会支持量表、心理韧性量表（resilience scale，RS）、戒烟动机量表对其调查。 结果 冠心病患者领悟社会支持、心理韧性与戒烟动机总分分别为（58.75±15.55）分、（128.79±22.98）分和（69.82±15.09）分。不同年龄、文化程度、婚姻状态的冠心病患者，其戒烟动机得分差异均有统计学意义（均P＜0.05）。戒烟动机与年龄、婚姻状态均呈负相关（均P＜0.01），与文化程度、领悟社会支持、心理韧性均呈正相关（均P＜0.01）。年龄、文化程度、婚姻状态、心理韧性直接影响戒烟动机，效应值分别为-0.222、0.148、-0.132、0.232；领悟社会支持不仅直接影响，还可通过心理韧性的中介效应影响戒烟动机，效应值为0.299。 结论 冠心病患者戒烟动机受到多种因素的综合影响，应加强老龄、较低学历、非在婚、领悟社会支持和心理韧性水平较低的冠心病患者的健康教育和干预工作。

Objective To explore the influencing factors of smoking cessation motivation in patients with coronary heart disease(CHD) based on structural equation model，and to provide theoretical reference for the development of effective intervention measures. Methods From July to December 2021，the convenience sampling method was used to select 464 patients with CHD in the outpatient department of 3 hospitals in Hangzhou.The general information questionnaire，Perceived Social Support Scale，Resilience Scale (RS) and Smoking Cessation Motivation Scale were used for a survey. Results The total scores of perceived social support，resilience and smoking cessation motivation of patients with CHD were (58.75±15.55)，(128.79±22.98) and (69.82±15.09) respectively.There were statistically significant differences in the level of smoking cessation motivation among CHD patients with different ages，education levels and marital status (all P＜0.05).Smoking cessation motivation was negatively correlated with age and marital status (all P＜0.01)，and positively correlated with education level，perceived social support and psychological resilience (all P＜0.01).Age，education level，marital status，and psychological resilience directly affected smoking cessation motivation，and the effect values were -0.222，0.148，-0.132，0.232，respectively.Perceived social support not only directly affected smoking cessation motivation，but also affected smoking cessation motivation through the mediating effect of resilience，with an effect value of 0.299. Conclusion The motivation of smoking cessation in patients with CHD is comprehensively affected by many factors.Health education and intervention should be strengthened in patients with CHD who are elderly，with low education background，unmarried，low perceived social support and low psychological resilience.
