The experimental group participates in the Mobio Health Multimedia Hypertension Education Program, which includes a hypertension health education manual and a mobile health (m-health) intervention, aimed at enhancing participants' health literacy and promoting health-enhancing behaviors.

In the control group, participants received the same hypertension health education manual as the experimental group.

The experimental group participates in the Mobio Health Multimedia Hypertension Promotion Program, which includes a hypertension education manual and a mobile health (m-health) intervention aimed at enhancing participants' health literacy and promoting healthy behaviors. In the first week, participants receive the health-education manual on-site, with face-to-face explanations and guidance on using mobile resources, such as text messaging, provided by the Sub-Investigator.

The mobile health intervention transforms the manual's content into six video units, each covering a specific topic, and these videos are continuously pushed over a two-month period. Distributed through LINE@, the official LINE account of the nursing platform, participants can easily access information via the chat menu at the bottom of the screen. This setup improves accessibility, making it convenient for participants to locate and use essential health information directly from the chat window.

A structured questionnaire survery was administered at the start, and at the 4th and 8th weeks of the intervention to evaluate its effectiveness. The questionnaire includes:(1) The Hypertension Health Literacy Scale, with scores ranging from 10 to 40, where higher scores indicate better outcomes; (2) The short-form Chinese Health-Promoting Lifestyle Profile, with scores ranging from 24 to 96, where higher scores indicate better outcomes.

A structured questionnaire was administered at the start, at weeks 4 and 8 of the intervention, and for post-intervention evaluation. The details are as follows: (1) Basic Characteristics, including age , gender, height (cm), weight (kg), BMI(weight and height will be combined to report BMI in in kg/m²), education, marital status, residential area, employment, economic status, living situation, clinic transportation, duration of hypertension, regular medication, and presence of other chronic diseases; (2) Hypertension Knowledge Scale( 0 to 10, higher scores = greater knowledge); (3) Adherence to Refills and Medications Scale (12-48, higher scores = better outcomes); (4) System Usability Scale, graded as: A (90-100), B (80-89), C (70-79), D (60-69), and F (0-59), with strong face validity and an average score of about 70; scores above 70 are considered acceptable; (5) Learning Satisfaction Questionnaire (12-60, higher scores= better outcomes).
