Many studies have investigated the relationships between cardiovascular diseases and patients' depression; nevertheless, few is still known as regard the impact of illness severity on depression and whether psychosocial variables mediate this association.
The aim of this study is to investigate the putative mediating role of illness representations, self-efficacy beliefs, and perceived social support on the relationship between illness severity and depression.
A total of 75 consecutive patients with cardiovascular disease (80 % men; mean age = 65.44, SD = 10.20) were enrolled in an Italian hospital. Illness severity was measured in terms of left ventricular ejection fraction, whereas psychological factors were assessed using self-report questionnaires.
The relationship between left ventricular ejection fraction and depression was mediated by identity illness perception, self-efficacy beliefs in managing cardiac risk factors, and perceived social support.
The treatment of depression in cardiovascular disease patients may therefore benefit from a psychological intervention focused on patients' illness representations, self-efficacy beliefs, and their perceived social support.
许多研究已经调查了心血管疾病与患者抑郁之间的关系；然而，对于疾病严重程度对抑郁的影响以及心理社会变量是否介导这种关联，仍知之甚少。
本研究旨在探讨疾病认知、自我效能信念和感知社会支持在疾病严重程度与抑郁之间的关系中的中介作用。
共纳入意大利一家医院的 75 名连续心血管疾病患者（80%为男性；平均年龄 65.44，标准差 10.20）。疾病严重程度采用左心室射血分数来衡量，而心理因素则使用自我报告问卷进行评估。
左心室射血分数与抑郁之间的关系受到疾病认知、管理心脏危险因素的自我效能信念和感知社会支持的中介作用。
因此，针对心血管疾病患者的抑郁的治疗可能会受益于一种专注于患者疾病认知、自我效能信念和感知社会支持的心理干预。
