TEXT4HF: A Randomized Controlled Trial of a Tailored Text Messaging Intervention to Improve Self-Care in Older Adult Patients With Heart Failure

In addition to usual care, participants in the intervention group will receive 5 TMs/week for 12 weeks at a time of their preference. Tailoring of the TMs is performed based on participants' responses to validated questionnaires (health beliefs scales, HF-knowledge scale, and self-efficacy about HF self-care scale), administered at baseline and 4 weeks. They will also receive an AHA HF discharge informational packet.
