Abstract 19199: The Effects of Self Efficacy and Social Support on Quality of Life of Patients and Family Caregivers After Coronary Artery Bypass Grafting
Introduction: Personal and social resources are critical factors in patient recovery after coronary artery bypass grafting (CABG). Family members are an importance source of support for the patient. Because of the importance of interdependent relationships, it is vital to examine associations between self efficacy, social support and quality of life at the dyadic level. No known studies have explored patient’s cardiac self efficacy and family caregiver’s perceptions of patient self efficacy and social support as influences on quality of life in CABG
Aims: To examine the effects of patient’s pre-operative cardiac self efficacy and family caregiver’s perceptions of patient self efficacy on their own and their partner’s quality of life after CABG; to examine the effects of patient’s and family caregiver’s preoperative social support on their own and their partner’s quality of life after surgery.
Methods: A total of 80 dyads completed questionnaires before and 4 months after CABG. Self-efficacy was assessed using the Cardiac Self Efficacy, social support was assessed using the MOS Social Support Survey, and quality of life assessed using the Short-Form 12 Health Survey. Longitudinal data were analysed using Multilevel modelling regression, the Actor-Partner Interdependence Model with distinguishable dyad regression.
Results: Of the 80 dyads, 75 were patient-spouse dyads. Patients were 80% males, aged 64.5 years and family caregivers were 90% females, aged 61.05 years. Patients’ tangible support exhibited an actor effect on their mental health,indicating low tangible support pre-operatively predicted their poorer mental health 4 months after CABG (β = .087, t = 2.059, p = 0.042). Patients’ self efficacy for maintaining function (SE-MF) exhibited a partner effect (β = -.768, t = 3.275, p = 0.002) on family caregivers physical health, indicating patient’s pre-operative SE-MF influenced the family caregivers health in a negative way.
Conclusions: Patient’s post-operative mental health was affected by their low pre-operative tangible support. The family caregivers physical health was negatively affected by patients self efficacy for maintaining function.
