To examine chain mediating roles of social support and self-efficacy between quality of frailty and depression in elderly people after percutaneous coronary intervention (PCI).
Frailty is a cause of depression among elderly patients after PCI. Although previous studies have shown that frailty, social support, self-efficacy and depression are significantly related, the interaction mechanism remains unclear.
Employing a cross-sectional research design and convenience sampling methodology, data were collected at a tertiary hospital in China. Participants completed the FRAIL Scale, Social Support Rate Scale, General Self-Efficacy Scale and the Hospital Anxiety and Depression Scale. We utilised the PROCESS macro in SPSS to ascertain the mediating roles of social support and self-efficacy between frailty and depression.
The study used the STROBE checklist for reporting.
A total of 241 elderly patients were included in the study, with an average age of 68.05 (6.04) years. Among them, 63.1% of the participants had experienced depression. Elderly patients after PCI's frailty score was negatively correlated with social support and self-efficacy, and positively correlated with depression. Social support was significantly positively correlated with self-efficacy, significantly negatively correlated with depression. Finally, self-efficacy was significantly negatively correlated with depression. Social support and self-efficacy mediated 11.61% and 29.46% of the total depressive role in elderly after frailty and PCI, respectively.
Frailty in elderly PCI patients is directly associated with depression and indirectly related through social support or self-efficacy.
To enhance the quality of life for elderly patients following PCI, healthcare providers should address the impact of frailty on depression and develop intervention strategies based on the levels of social support and self-efficacy.
Questionnaires filled out by patients were used to understand the relationship between frailty, social support, self-efficacy and depression.
探讨经皮冠状动脉介入治疗（PCI）后老年人衰弱质量与抑郁之间社会支持和自我效能的链式中介作用。
衰弱是PCI术后老年患者抑郁的一个原因。尽管先前的研究表明衰弱、社会支持、自我效能和抑郁之间存在显著相关性，但相互作用机制仍不清楚。
采用横断面研究设计和便利抽样方法，在中国一家三级医院收集数据。参与者完成了衰弱量表、社会支持率量表、一般自我效能量表和医院焦虑抑郁量表。我们使用SPSS中的PROCESS宏来确定社会支持和自我效能在衰弱与抑郁之间的中介作用。
该研究使用STROBE清单进行报告。
本研究共纳入241例老年患者，平均年龄为68.05（6.04）岁。其中，63.1%的参与者经历过抑郁。PCI术后老年患者的衰弱评分与社会支持和自我效能呈负相关，与抑郁呈正相关。社会支持与自我效能呈显著正相关，与抑郁呈显著负相关。最后，自我效能与抑郁呈显著负相关。社会支持和自我效能分别介导了衰弱和PCI后老年人总抑郁作用的11.61%和29.46%。
老年PCI患者的衰弱与抑郁直接相关，并通过社会支持或自我效能间接相关。
为提高PCI术后老年患者的生活质量，医疗服务提供者应关注衰弱对抑郁的影响，并根据社会支持和自我效能水平制定干预策略。
使用患者填写的问卷来了解衰弱、社会支持、自我效能和抑郁之间的关系。
