Abstract: Background: Hypertension is a significant public health concern and a major risk factor for cardiovascular disease, stroke, and renal complications. It is often asymptomatic, earning the moniker ?silent killer.? In India, the burden of hypertension is rising, especially in rural areas where awareness and access to preventive education are limited. The Dietary Approaches to Stop Hypertension (DASH) diet has proven effective in reducing blood pressure and associated cardiovascular risks. Objective: To evaluate the effectiveness of a self-instructional module (SIM) on improving knowledge about the DASH diet among hypertensive clients in selected rural areas. Methods: A quantitative, pre-experimental one-group pretest-posttest design was adopted. A total of 90 hypertensive clients were selected using purposive sampling. Data were collected using a structured questionnaire covering socio-demographic data and DASH diet knowledge. The SIM was administered after the pretest, and a posttest was conducted after 7 days. Descriptive statistics, paired t-test, and chi-square test were used for analysis. Tool reliability was established with Karl Pearson?s correlation coefficient (r = 0.78). Results: A significant increase in knowledge scores was observed post-intervention (t = 31.44; p < 0.05). Age was found to be significantly associated with pretest knowledge scores (?? = 12.83; ??_tab = 12.59), indicating demographic influence on baseline knowledge levels. Conclusion: The self-instructional module effectively enhanced awareness regarding the DASH diet among hypertensive individuals. It serves as a low-cost, scalable educational tool that can be integrated into rural health promotion strategies.
