Methods
hypertensive
An interventional study with a quasi-experimental design, was conducted on 118 uncontrolled hypertensive patients. Participants were randomly divided into the intervention (n = 59) and control (n = 59) groups using blocked randomization. In the intervention group, a mobile health (M-health) program was designed using programmed instruction to improve patients’ health literacy over a period of 3 months. Data was collected by administering health literacy and medication adherence questionnaires to participants before and after the intervention. The analysis involved using the independent sample t-test to compare the variables before and after the study.
