Diabetes mellitus (DM) requires adequate patient knowledge to support effective self-management and prevent complications. Video-based education provides an audiovisual learning method that may improve patients' understanding of diabetes management. To examine the effect of video-based education on diabetes mellitus management knowledge among patients attending the Cempaka Putih Community Health Center, Central Jakarta. A quantitative quasi-experimental study with a pretest–posttest control group design was conducted from September to October 2025. A total of 68 patients with DM were recruited using purposive sampling and allocated into intervention (n=34) and control (n=34) groups. The intervention group received standardized video-based education on diabetes management, whereas the control group received routine health education. Knowledge was measured using a 20-item questionnaire before and after the intervention. Data were analyzed using paired-samples t-tests, independent-samples t-tests, and multiple linear regression. Baseline knowledge scores were comparable between the intervention (9.68 ± 2.47) and control groups (9.71 ± 3.79). Following the intervention, the mean knowledge score increased significantly to 14.09 ± 1.54 in the intervention group (p < 0.001), whereas no significant change was observed in the control group (9.76 ± 3.39; p = 0.737). The mean knowledge improvement differed significantly between groups (4.41 ± 2.84 vs. 0.06 ± 1.01; p < 0.001). Age significantly influenced knowledge improvement (p = 0.001), while sex, education, and duration of DM were not significant predictors. Video-based education effectively improved diabetes management knowledge and may be integrated into primary healthcare education programs for patients with DM.
