Building Respectful Online Space (BROS): Evaluating a Co-designed Anti-cyberbullying Intervention Among Adolescents

Summary

Background: The growing prevalence of cyberbullying throughout the world indicates the importance of anti-cyberbullying interventions, especially for adolescents. While few interventions target cyberbullying, content from different regions may not necessarily apply to local contexts, adolescents' viewpoints were not considered in the past designs, few local RCTs, and unclear sustainability.

Objectives: To evaluate the feasibility, acceptability and preliminarily effects of the co-designed anti-cyberbullying intervention: Building Respectful Online Space (BROS).

Methods: A sample of around 90 aged 12 to 15 will be recruited from secondary schools in Hong Kong. This study will adopt a 2-arm experimental trial. Each class will be randomly assigned equally into the intervention arm (BROS) and control arm (Heathy Diet), and eligible students will be allocated to either arm accordingly. The intervention will be provided in one or 3 days based on the school schedule. Participants will be assessed at baseline, 3 weeks later, and 12-week follow-up assessments. The primary outcome is cyberbullying behaviour of perpetration and victimisation; the secondary outcome includes cyberbullying attitudes, sleep quality, and psychosocial well-being. Feasibility and acceptability will be assessed. And generalised estimating equations analysis will be used to investigate the research objectives.

Potential contributions: The results of this study will provide evidence-based support for using a blended approach to prevent cyberbullying, promote psychosocial well-being, and promote sleep health. This intervention is dedicated to using evidence-to-user-driven ideas to develop culturally sensitive interventions to effectively prevent cyberbullying in the future.
