背景：随着治疗水平的提高，心力衰竭患者的寿命延长，护理大多在家中进行，主要由伴侣提供帮助。对心力衰竭的感知控制对于管理自我保健活动以维持患者及其家人的健康是重要的。心衰患者及其家属的抑郁症状与健康状况受损有关。然而，关于抑郁症状如何影响心力衰竭患者及其同居伴侣的健康状况和对心力衰竭的感知控制之间的关系的知识有限。目的：本研究旨在探讨心力衰竭患者及其伴侣的抑郁症状是否介导了感知控制与健康状况（即精神和身体）之间的关系。方法：在这一次要资料分析中，我们纳入了132名心力衰竭患者和132名伴侣，他们完成了抑郁症状（贝克抑郁量表II）、感知控制（控制态度量表）和身心健康状况（短格式-36）的测量。采用一系列多元回归分别对患者及其家庭照顾者进行了抑郁的中介作用检验。结果：我们发现抑郁症状在患者和伴侣的感知控制与心理健康状况的关系中起中介作用。感知控制与身体健康状况之间的关系是由患者的抑郁症状介导的，而不是由伴侣的抑郁症状介导的。结论：在抑郁症状得到有效控制的情况下，通过感知控制来改善自我保健管理和维持可能更有效。
Background: As treatment has improved, patients with heart failure live longer, and the care mostly takes place at home with partners providing the main assistance. Perceived control over heart failure is important in managing self-care activities to maintain health in patients and their family. Depressive symptoms are associated with impaired health status in patients with heart failure and their family. However, there is limited knowledge about how depressive symptoms affect the relationship between health status and perceived control over heart failure in patients with heart failure and their cohabiting partners. Aim: The aim of this study was to examine whether the relationship between perceived control and health status (i.e. mental and physical) was mediated by depressive symptoms in patients with heart failure and their partners. Methods: In this secondary data analysis, we included 132 heart failure patients and 132 partners who completed measures of depressive symptoms (the Beck depression inventory II), perceived control (the control attitude scale), and physical and mental health status (the short form-36) instruments. The mediation effect of depression was examined using a series of multiple regression in patients and their family caregivers separately. Results: We found a mediator effect of depressive symptoms in the relationship between perceived control and mental health status in both patients and partners. The relationship between perceived control and physical health status was mediated by depressive symptoms in the patients, not in the partners. Conclusion: Efforts to improve self-care management and maintenance by targeting perceived control may be more effective if depressive symptoms are also effectively managed.
