Abstract
INTRODUCTION: Bullying is a persistent, aggressive behavior characterized by a significant power imbalance that severely affects students’ mental and social well-being. Moreover, nurses serve as health educators in schools. They are well positioned to deliver psychoeducation that raises awareness of bullying and supports prevention. OBJECTIVE: To determine the effect of nurse-led psychoeducation on high school students’ awareness of the dangers of bullying in Bandung, Indonesia. METHOD: A quasi-experimental, pre- and post-test design was employed with a control group and an intervention group. A total of 100 high school students in Bandung were randomly assigned, with 50 in the intervention group and 50 in the control group. For three months, nurses delivered four psychoeducation sessions on bullying to the intervention group. Meanwhile, the control group continued routine activities. Awareness was measured using the Bullying Danger Awareness Questionnaire before and after the intervention. Data analysis was performed using the Wilcoxon and Mann-Whitney tests. RESULTS: The intervention group showed significant improvement in awareness of the dangers of bullying compared to the control group (p < 0.001). CONCLUSION: Nurse-led psychoeducation improves students’ awareness of bullying risks. Future studies should evaluate behavioral change and longer-term effects using larger samples and follow up. CLINICAL TRIAL NUMBER: Not applicable.
