社会支持对心力衰竭患者D型人格与自我照顾行为的中介作用
摘要
目的
心力衰竭患者对自我护理行为的依从性较差。最近的研究表明，D型人格，社会支持与慢性病患者的自我保健行为之间存在联系。然而，这种关系的基础机制在心力衰竭患者中很少受到研究的关注。本研究旨在确定社会支持对心力衰竭患者D型人格与自我照顾行为之间关系的中介作用。
设计
描述性横断面设计。
方法
样本包括170名18岁以上的患者，他们被诊断出心力衰竭超过6个月，并前往首尔的一家三级大学医院就诊。从2019年4月至7月，通过使用结构化问卷进行访谈和两名受过训练的研究助理对病历的审查收集数据。使用SPSS PROCESS程序测试了多个回归模型，以确定中介变量的重要性。
结果
心力衰竭患者中D型人格的患病率为20.0％。在D型人格，社会支持和自我照顾行为之间发现了重要的关联。结果显示出间接影响，表明D型人格对自我护理行为的影响是由社会支持介导的。
结论
具有D型性格的心力衰竭患者可能缺乏社交支持，这可能影响了他们对自我护理行为的依从性。因此，为了促进持久的自我保健行为，为D型人格患者提供支持性保健或教育计划至关重要。
影响
提供可持续的社会支持可以对具有D型性格的心力衰竭患者的长期自我护理维护产生积极影响。需要进一步研究以进一步阐明D型人格，社会支持和自我保健行为之间关系的潜在机制。
英文摘要
Aims
Patients with heart failure exhibit poor adherence to self‐care behaviours. Recent studies have shown a link between Type D personality, social support, and self‐care behaviours of patients with chronic diseases. However, the mechanisms underlying this relationship have received little empirical attention in those with heart failure. This study aimed to identify the mediating effects of social support in the relationship between Type D personality and self‐care behaviours in patients with heart failure.
Design
This study employed a descriptive cross‐sectional design.
Methods
The sample comprised 170 patients aged over 18 years who had been diagnosed with heart failure for over 6 months and visited a tertiary care university hospital in Seoul. From April–July 2019, data were collected through an interview conducted using a structured questionnaire and a review of medical records by two trained research assistants. Multiple regression models were tested using the SPSS PROCESS procedure with bootstrapping to determine the significance of the mediation.
Results
The prevalence of Type D personality in patients with heart failure was 20.0%. Significant associations were identified among Type D personality, social support, and self‐care behaviours. Results revealed an indirect effect, suggesting that the effects of Type D personality on self‐care behaviours were mediated by social support.
Conclusion
Heart failure patients with Type D personality were likely to lack social support, which may have influenced their low adherence to self‐care behaviours. Thus, to facilitate long‐lasting self‐care behaviours, it is vital to provide supportive care or educational programs for patients with Type D personality.
Impact
Providing sustainable social support can have a positive impact on the long‐term self‐care maintenance of patients with heart failure patients who have a Type D personality. Future studies are required to further elucidate the underlying mechanisms of the relationship between Type D personality, social support, and self‐care behaviours.
