Brief Summary

The goal of this clinical trial is to learn whether a digital education program can help people with high blood pressure (hypertension) manage their condition better. The program aims to improve self-care behaviors and health literacy by teaching participants how to use digital tools, follow healthy lifestyle habits, and take their medicines regularly. Researchers will compare two groups. One group will receive digital education that includes short videos, brochures, and podcasts about blood pressure control and how to use online health platforms such as e-Nabız (Turkey's national e-health system). The other group will not receive this education. Participants will attend two sessions during two weeks. The main questions are: Does digital education improve self-care and e-health literacy in people with hypertension? Does it help participants take their medicine as prescribed and maintain healthy habits such as diet and exercise?

Outcome Measures

Primary Outcomes (2)

• Change in Hypertension Self-Care Behaviour Score

  Change in the Hypertension Self-Care Profile Behaviour Subscale score from baseline to Week 4. Scores range from 11 to 44, with higher scores indicating better hypertension self-care behaviour.

  The 4-week programme comprised two individual face-to-face educational sessions in Week 1, each lasting 15-20 minutes, followed by a PowerPoint presentation delivered via WhatsApp in Week 2, an illustrated brochure in Week 3, and a podcast in Week 4.

• Change in Hypertension Self-Care Self-Efficacy Score

  Change in the Hypertension Self-Care Profile Self-Efficacy Subscale score from baseline to Week 4. Scores range from 12 to 48, with higher scores indicating greater hypertension self-care self-efficacy.

  The 4-week programme comprised two individual face-to-face educational sessions in Week 1, each lasting 15-20 minutes, followed by a PowerPoint presentation delivered via WhatsApp in Week 2, an illustrated brochure in Week 3, and a podcast in Week 4.

Secondary Outcomes (2)

• Change in Hypertension Self-Care Motivation Score

  The 4-week programme comprised two individual face-to-face educational sessions in Week 1, each lasting 15-20 minutes, followed by a PowerPoint presentation delivered via WhatsApp in Week 2, an illustrated brochure in Week 3, and a podcast in Week 4.

• Change in Perceived eHealth Literacy Score

  The 4-week programme comprised two individual face-to-face educational sessions in Week 1, each lasting 15-20 minutes, followed by a PowerPoint presentation delivered via WhatsApp in Week 2, an illustrated brochure in Week 3, and a podcast in Week 4.

NO INTERVENTION

After completion of the Week 4 assessment, the same educational materials were provided to the control group via WhatsApp.

Interventions

Hypertension Self-Management and E-Health Education BEHAVIORAL

The education program consists of two sessions designed for hypertension management, combining self-care and e-health literacy.Each session is planned to last 15-20 minutes. The first session covers hypertension and healthy lifestyle changes (nutrition, exercise, stress management, etc.).The second session introduces e-health tools (digital blood pressure monitor apps, etc.) and systems like e-Nabız and MHRS, including practical demonstrations.The education is supported by visual-aided video narrations, plain-language brochures, sample screenshots, and live applications. Participants practically demonstrate logging into e-health systems and tracking data using their own mobile devices or provided digital tools. The intervention is conducted twice, once a week for two weeks. At the end of each session, knowledge and application skills are assessed through short evaluation questions. Post-education changes in individuals' hypertension management and e-health literacy levels are measured

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: No masking will be applied in this study. Both participants and researchers will be aware of group assignments due to the nature of the digital education intervention.
• Purpose: SUPPORTIVE CARE
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Prof. Dr. Ayfer Bayındır Çevik

Model Details: This study uses a randomized controlled, parallel-group, pre-test/post-test design to evaluate the effect of digital education on self-care behaviors and health literacy in adults with hypertension. Participants will be randomly assigned to either the intervention or control group. The intervention group will receive a structured two-session digital education program delivered over two weeks. The program includes short videos, brochures, and podcasts focusing on blood pressure management, medication adherence, lifestyle changes, and e-health literacy skills such as using digital tools like e-Nabız and MHRS. The control group will receive standard routine care without any digital training during the study. Both groups will complete pre- and post-intervention assessments using validated scales to measure self-care, e-health literacy, and medication adherence. Data will be analyzed to determine the effectiveness of the digital education model in improving hypertension self-management.
