Caregiving has been associated with negative psychological and physical consequences for years (Molloy, Johnston, & Witham, 2005). Some research indicates that caregivers with higher perceived control may experience fewer negative consequences of caregiving (Wallhagen, 1993). Little is known about caregivers of heart failure patients.
The primary purpose of this study was to test a conceptual model of caregiver outcomes among caregivers of heart failure patients. Testing of the model determined which of the demographic and biological factors of the caregiver (age, gender, anxiety, depressive symptoms, and comorbidity), the patient (NYHA class), caregiver burden (task time and task difficulty), and perceived control explained caregiver emotional and physical health. The secondary purpose was to determine the influence of the same caregiver, patient, and burden factors on caregiver perceived control. Perceived control was hypothesized to mediate caregiver burden and caregiver outcomes.
A descriptive design with cross-sectional data collection was used among 63 caregivers of patients with heart failure. The proposed model of caregiving outcomes was partially supported by the data. Stepwise regression analysis indicated caregiver burden (task difficulty), depressive symptoms, and age were significant explanatory variables of emotional health (R2 = .43). Anxiety and caregiver burden (task time) explained 23% of the variance in emotional health. Depressive symptoms, caregiver age, caregiver comorbidity, and patient NYHA class were significant explanatory variables of physicalhealth (R2 = .35). Caregiver burden-time and depressive symptoms were significant in the regression model for caregiver perceived control (R2 = .30, F = 4.05, p = .005). The data also suggested that perceived control may have a mediator role between caregiver burden and caregiver emotional health. Further prospective, longitudinal studies with larger more diverse samples are warranted to confirm these results along with the use of reliable valid scales applicable to the caregiver of HF patient population.
