The Impact of Self-management Knowledge and Support on the Relationships Among Self-efficacy, Patient Activation, and Self-management in Rural Patients With Heart Failure.

Convenience sampling from one rural hospital in Southeast Nebraska limits how far these findings apply to other heart failure populations. The final analysis included 100 patients, so the results may be unstable and need confirmation in a larger and more diverse sample. Patients who enrolled in the parent trial may have been more confident or more engaged in self-management than patients who declined. The sample included more women than men, which could affect generalizability. This is a secondary analysis of associations at 3 months, not a new test of whether changing self-efficacy, activation, knowledge, or support causes better self-management. The 12-week home-based intervention details are not reported here, so clinicians cannot tell which components were delivered. Measures of self-management knowledge and support were described as rudimentary and heterogeneous, so it is unclear which specific knowledge or support elements mattered.

Do not conclude that building self-efficacy or patient activation will improve self-management in every heart failure patient. The study only showed associations at 3 months, and the mediating effect was significant only for patients with low self-management knowledge; for patients with high knowledge, neither confidence nor activation predicted self-management.
