VALIDITY AND PRACTICALITY OF A DASH DIET E-BOOKLET FOR HYPERTENSIVE PATIENTS IN PRIMARY HEALTH CARE

Abstract

Hypertension is a major non-communicable disease that requires appropriate dietary management to prevent complications. Educational media play an important role in improving patients’ understanding of hypertension management, including the implementation of the Dietary Approaches to Stop Hypertension (DASH) diet. This study aimed to develop and evaluate the validity and practicality of a DASH Diet e-booklet for hypertensive patients in the working area of Lubuk Buaya Public Health Center, Padang. This research employed a Research and Development (R&D) approach using the ADDIE model consisting of Analysis, Design, Development, Implementation, and Evaluation stages. Product validation was conducted by two material experts and two media experts, while practicality testing involved 15 hypertensive patients. Data were collected using validation questionnaires, practicality questionnaires, and pre-test and post-test instruments. The results showed that the e-booklet obtained a validity score of 79% from material experts and 75% from media experts, both categorized as valid. The practicality test yielded a score of 84.27%, categorized as very practical. Furthermore, respondents’ knowledge increased from 58% before intervention to 82% after intervention, indicating a 24% improvement. These findings indicate that the developed DASH Diet e-booklet is valid, practical, and potentially useful as an educational medium for hypertensive patients.
