| Summary: | Hypertension is a disorder that needs to be kept in check, as it can lead to cardiovascular diseases, renal failure, and if left unmanaged, to loss of life. Laboratory investigations have revealed that lifestyle alterations, such as changes in the dietary routine, can serve to keep hypertension under control. Among the productive means, of promoting adjustments, in the diet of hypertension patients are educational videos. This study delves into the development and validation of educational videos, aimed at encouraging dietary adjustments among hypertension sufferers. The design and developmental research (DDR) methodology was harnessed for this investigation. The process comes with three phases: (I) content analysis, (II) design and development and (III) evaluation. The objectives, structure/presentation and relevance of the educational videos were scrutinized by way of the Educational Content Validation Instrument in Health. Generally, I-CVI, S-CVI/Ave and S-CVI/UA for each domain met an acceptable content validity level, while several alterations were required for domain Objectives (S-CVI/Ave: 0.91, S-CVI/UA: 0.80) and Structure/Presentation (S-CVI/Ave: 0.93, S-CVI/UA: 0.60). However, no alterations were necessary for domain Relevance (S-CVI/Ave: 1.0, S-CVI/UA: 1.0). Given the abundance of existing educational videos on dietary management for hypertension, the creation of videos in this study and impartial evaluation of these materials would be advantageous for instructional purposes. This study demonstrated that the video content was valid and acknowledged by experts. This information would serve as a dependable and fact-verified means, for the management of hypertension, through dietary adjustments. © 2021 Institute of Health Promotion and Education.
