Efficacy of Bystander Intervention Program in Nursing Students

This randomized controlled trial evaluated the effectiveness of a bystander intervention program for dating violence among nursing students. The study was conducted with second-year nursing students at Istanbul University-Cerrahpaşa Florence Nightingale Faculty of Nursing. A total of 84 students were randomized to the intervention and control groups. Due to missing data from one participant in the control group, 83 students were included in the final analysis (intervention group, n=42; control group, n=41). Participants were allocated to the groups using computer-generated randomization. The intervention group received the Bystander Intervention Program, which was developed based on the Bystander Behavior Model and the Theory of Planned Behavior and adapted to the cultural and institutional context. The control group received a single 90-minute educational session on dating violence during the study period. After completion of all outcome assessments, participants in the control group were also offered the Bystander Intervention Program for Dating Violence. Data were collected face-to-face using an Individual Information Form, the Bystander Efficacy Scale, the Intention to Help Scale-Short Version, the Bystander Behavior Scale, and a Program Evaluation Form. Bystander efficacy and intention to help were assessed at baseline, immediately after the intervention, and at two-month follow-up. Bystander behavior was assessed at baseline and at two-month follow-up.
