Description
Summary:•Self-efficacy is associated with whether a patient performs heart failure self-care.•Depression is associated with self-care through self-efficacy.•Interventions targeting self-efficacy may benefit self-care performance. Patients with inadequate health literacy and heart failure face high healthcare costs, more hospitalizations, and greater mortality. To address these negative consequences, patients need to improve heart failure self-care. Multiple factors may influence self-care, but the exact model by which they do so is not fully understood. The objective of this study was to examine a model exploring the contribution of health literacy, depression, disease knowledge, and self-efficacy to the performance of heart failure self-care. Using a cross-sectional design, patients were recruited from a heart failure clinic and completed validated assessments of their cognition, health literacy, depression, knowledge, self-efficacy and self-care. Patients were separated into two groups according to their health literacy level: inadequate/marginal and adequate. Differences between groups were assessed with an independent t-test. Hypothesized paths and mediated relationships were estimated and tested using observed variable path analysis. Participants (n = 100) were mainly male (67%), white (93%), and at least had a high school education (85%). Health literacy was associated with disease knowledge (path coefficient=0.346, p = 0.002), depression was negatively associated with self-efficacy (path coefficient=-0.211, p = 0.037), self-efficacy was positively associated with self-care (path coefficient=0.402, p
