About

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

Full 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.
