Aims. This research aimed to evaluate the effectiveness of educational interventions based on the Health Belief Model (HBM) in enhancing hypoglycemia prevention skills among individuals with diabetes mellitus (DM).

Methods. A quasi-experimental study design was utilized, incorporating a two-group pre-test and post-test framework. Seventy-two participants were recruited through purposive sampling and divided equally into intervention and control groups, with 36 individuals in each. The intervention group received education through an HBM-guided mobile application, while the control group utilized a pocketbook for educational purposes. Participants’ skills in preventing hypoglycemia were assessed before and after a two-month intervention period using a validated questionnaire. Data were analyzed using paired and independent t-tests, with statistical significance set at p < 0.05.

Results. The intervention group demonstrated a notable improvement in hypoglycemia prevention skills, with mean scores increasing from 48.11 ± 6.17 at baseline to 55.89 ± 6.92 post-intervention (p = 0.0001). In contrast, the control group showed only a modest increase, from 43.17 ± 4.75 to 45.39 ± 5.93 (p = 0.0001). Post-intervention comparisons revealed a statistically significant difference in skill levels between the two groups (p = 0.0001).

Conclusion. The HBM-based education model effectively improved the ability of DM patients to prevent hypoglycemia. This technology-based intervention can serve as an innovative approach to health education for DM patients
