An increase in caregiver burden and a decrease in social support have both been identified as predictors of poor caregiver psychological distress. However, little is known about the role of these factors in coronary artery bypass graft (CABG) caregivers. The purpose of this study was to investigate whether change in perceived social support from pre to post surgery mediated the relationship between change in caregiver burden and caregiver depressive symptoms and subjective well-being post surgery. A sample of 101 caregivers of elective CABG patients were assessed 28 days before and 62 days after patients' surgery. Caregivers completed the Oberst Burden Scale, the Enhancing Recovery in Coronary Heart Disease (ENRICHD) Social Support Instrument, the Beck Depression Inventory, and the Control, Autonomy, Self-Realisation, and Pleasure (CASP-19) scale. Simple mediation analyses showed that change in social support significantly mediated both the relationship between change in caregiver burden and post-surgery depressive symptoms (unstandardised β = 0.041, 95% CI (0.005, 0.112)) and the relationship between change in caregiver burden and post-surgery subjective well-being (unstandardised β = 0.071, 95% CI (0.001, 0.200)). Psychological interventions aimed at the CABG caregiver population should promote social support to deal with the increase of caregivers' tasks and demands after the patients' surgery.
照料者负担增加和社会支持减少都被认为是照料者心理困扰的预测因素。然而，人们对这些因素在冠状动脉旁路移植术（CABG）照料者中的作用知之甚少。本研究旨在探讨术后感知到的社会支持变化是否在照料者负担变化与照料者抑郁症状和术后主观幸福感之间的关系中起中介作用。对 101 名择期 CABG 患者的照料者在患者手术前 28 天和术后 62 天进行了评估。照料者完成了 Oberst 负担量表、增强冠心病康复的社会支持量表、贝克抑郁量表和控制、自主、自我实现和快乐量表（CASP-19）。简单中介分析表明，社会支持的变化显著中介了照料者负担变化与术后抑郁症状之间的关系（未标准化β=0.041，95%置信区间（0.005，0.112））以及照料者负担变化与术后主观幸福感之间的关系（未标准化β=0.071，95%置信区间（0.001，0.200））。针对 CABG 照料者群体的心理干预措施应促进社会支持，以应对患者手术后照料者任务和需求的增加。
