The long-term goal of the proposed study is to empower people with heart failure (HF) to effectively perform HF self-care. The objectives of the study are to: (1) explore the acceptability and feasibility, and (2) examine the preliminary efficacy of the health literacy-based HF self-care intervention (H2Lit). Subject Population: People with HF aged 40 years or older. Research Design: 2-arm, single-blind, randomized controlled pilot study. Instrument: (1) HF-specific health literacy scale, (2) Atlanta HF knowledge test, (3) Self-care Confidence scale, and (4) Self-care of HF index Procedure: After the informed consent (e-consent) is obtained, the participant will then be directed to the online baseline questionnaire. After completion of the baseline questionnaire, participants will then be randomized to either the Intervention Group or the Control Group using the randomization feature in REDCap Intervention Group (IG): IG participants will be provided with the link and log-in information to access H2Lit. Control Group (CG): CG participants will be provided with a copy of the American Heart Association Living with HF brochure. A week prior to the 90-day mark, the participants will receive a link to the online assessment questionnaire.
