Key result
Declining social support mediates the link between increased caregiver burden and post-surgery depression.
Why the study?
Caregiver burden and decreased social support predict psychological distress, but little is known about their role in coronary artery bypass graft surgery caregivers.
Does change in caregiver burden impact post-surgery depressive symptoms and well-being in CABG caregivers, and is this effect mediated by changes in perceived social support?
Cohort (n=101)
No
Does change in caregiver burden impact post-surgery depressive symptoms and well-being in CABG caregivers, and is this effect mediated by changes in perceived social support?
A decline in perceived social support mediates the negative effects of caregiving burden on mental well-being and depressive symptoms following a partner's CABG surgery.
Declining social support may link caregiver burden to post-CABG depressive symptoms; hypothesis-generating and requires prospective confirmation before practice change.
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.

Solorzano et al. (2021) conducted a cohort in Caregivers of coronary artery bypass graft (CABG) patients (n=101). Change in caregiver burden and perceived social support was evaluated on Mediatory effect of social support on the relationship between change in caregiver burden and post-surgery depressive symptoms (unstandardised β = 0.041, 95% CI 0.005-0.112). A reduction in perceived social support over time significantly and fully mediated the relationship between increased caregiver burden and higher post-surgery depressive symptoms (unstandardised β = 0.041, 95% CI 0.005-0.112).
