Episodic Future Thinking to Improve Anticoagulant Adherence in Atrial Fibrillation

Participants will engage in episodic future thinking prompted via text-based cues and picture-based cues to help them adhere to oral anticoagulants. Participants will also receive health education on atrial fibrillation-related stroke prevention.

The control group will receive standard care, including routine health education from ward nurses and one post-discharge telephone follow-up. In additon, participants will receive a message from the researcher at the same time point each day, but the message will only involve daily greetings.
