Heart failure (HF) is common form of cardiac dysfunction that affects over five million Americans and is responsible for upwards of 32% of preventable hospital re-admissions each year in adults over the age of 65 [1,2]. Cardiac function progressively worsens, resulting in advanced symptoms (i.e., dyspnea, fluid retention, and activity intolerance) and an increased need for assistance with activities of daily living [3,4]. The decline in physical function that accompanies HF necessitates a need for assistance and support by others to influence disease-related outcomes (i.e., quality of life, event-free survival, depressive symptoms) [5-8]. Consequently, social support plays a critical role in assisting individuals with HF to maintain their physiological and psychological well-being [9,10]. In fact, evidence suggests that social support is vital and aids in influencing self-care behaviours in those with HF, by indirectly affecting self-care management through self-care confidence and influencing treatment adherence [11,12]. Family support, particularly, aids in symptom assessment and management and in the problem-solving process regarding treatment-seeking decisions for symptoms of HF [13,14]. Family support is also instrumental in providing assistance with daily activities (e.g., cooking, cleaning, and home maintenance) as HF progresses and functional ability is impacted [15].
