摘　　要：目的:探讨自我效能感在经皮冠状动脉介入治疗(PCI)术后患者D型人格与体力活动间的中介作用。方法:2021年11月至2022年10月,采用一般资料调查表、D型人格量表、心脏锻炼自我效能量表和国际体力活动问卷对广东省3所三甲医院心血管内科住院复查的328例PCI术后患者进行调查,使用SPSS 27.0软件和PROCESS插件进行中介效应分析。结果:PCI术后患者体力活动耗能为1194.00(621.00,2112.75)MET-min/w;D型人格评分为(19.72±6.34)分,D型人格检出率为32.6%(107人),非D型人格为67.4%(221人);自我效能感得分为(47.70±8.12)分。D型人格与体力活动、自我效能感均呈负相关(r_(s)=-0.296,-0.275,P<0.001),体力活动和自我效能感呈正相关(r_(s)=0.579,P<0.001)。自我效能感在D型人格和体力活动之间存在部分中介效应,中介效应值为-0.171,中介效应占总效应的41.8%。结论:D型人格可直接影响体力活动,又可以通过自我效能感间接影响PCI术后患者的体力活动。Objective:To explore the mediating effect of self-efficacy between type D personality and physical activity in patients after percutaneous coronary intervention(PCI).Methods:Using a general information questionnaire,the type D personality scale,the cardiac exercise self-efficacy instrument,and the international physical activities questionnaire,328 post-PCI patients who were hospitalized for review in the cardiovascular medicine departments of three tertiary hospitals in Guangdong Province were investigated between November 2021 and October 2022.The SPSS 27.0 software and PROCESS plug-in were used to analyze mediating effects.Results:Following PCI,patients' energy consumption from physical activity was 1194.00(621.00,2112.75)MET-min/w;The total score of type D personality was(19.72±6.34),the percentage of patients with type D personality was 32.6%(107)and the percentage of non-type D personality was 67.4%(221).The total score of self-efficacy was(47.70±8.12).The type D personality was negatively correlated with physical activity and self-efficacy(r_(s)=-0.296,-0.275,P<0.001),while physical activity was positively correlated with self-efficacy(r_(s)=0.579,P<0.001).Self-efficacy played a partial mediating effect between type D personality and physical activity.The mediating effect value was-0.171,accounting for 41.8%of the total effect.Conclusion:Type D personality can affect the physical activity of the patients directly and indirectly after PCI through self-efficacy.
