Brief Summary

This study utilizes the I-Change Model to empower individuals in literacy-limited settings, where the majority of the population is illiterate. By leveraging multimedia tools-such as an educational video and a pictorial infographic-we aim to promote self-care practices among individuals suffering from hypertension. Through these tailored interventions, we seek to enhance awareness, improve hypertension management, and encourage behavioral change, even in low-literacy communities

Detailed Description

This study is grounded in the I-Change Model, a behavioral change framework that emphasizes awareness, motivation, and ability as key drivers for adopting healthier lifestyles. Recognizing the barriers posed by low literacy in many underserved communities, particularly in urban slums, we aim to implement context-sensitive interventions that empower individuals with hypertension to take charge of their health. In these settings, traditional written health education materials often fail to reach or resonate with the population due to widespread illiteracy and limited health literacy. To address this gap, our study introduces two key multimedia tools: an educational video, designed with simple language and culturally relevant visuals to demonstrate self-care techniques; and a pictorial infographic that visually conveys essential information about hypertension management, medication adherence, dietary habits, and physical activity. By combining these tools with physician consultations, we hope to strengthen patient understanding, increase engagement with self-care practices, and ultimately improve blood pressure control. This multimedia-based, patient-centered approach offers a scalable and cost-effective strategy for promoting behavioral change in marginalized, low-literacy populations.

Study Groups

Control Arm: Standardized clinic care with Doctor Advice

In this arm, patient will receive all doctor's consultation and standardized care provided in the clinic setting.

Group Type: NO_INTERVENTION

No interventions assigned to this group

Intervention :" Educational Intervention through pictorial infographs"

Standardized clinic care + pictorial info-graphs distribution at every follow-up visit

Group Type: EXPERIMENTAL

Behavior Change through Education intervention

Intervention Type: OTHER

The I-Change Model We used behavior alteration theory to identify areas of thinking or conduct that might potentially lead to issues in the process of collecting or consuming medicine. Subsequently, we proceeded to create and improve the substance of the message, and we aligned the messages with a standardized classification of evidence-based strategies for modifying behavior.

Unclear or confusing information in infographics and television videos was revised, while information that was deemed unhelpful or insignificant by both patients and clinicians was eliminated. Patients' feedback was used to create fresh material for television videos and infographics.

1. Encourage patients about routine clinic appointments

2. Provide relevant health-related information.

3. Help participants plan and organize various treatment adherence behaviors including medication collection and taking, diet, and exercise

4. Support positive adherence-related behaviors

Intervention : "Education intervention through video of self-care in LCD"

Standardized clinic care + hypertension care enhanced Video message in the local language at the waiting area through fastening LCD of the designated cluster.
