Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Cyberbullying behaviour

    The Cyberbullying Behaviour Scale (CBBS) consists of E-Victimisation Scale (E-VS) and the E-Bullying Scale (E-BS), is the validated 11-item scale for measuring cyberbullying behaviour. The scale consist of two domain: 5-item of E-VS and 6-item of E-BS for adolescents with a 7-point Likert scale (Lam \& Li, 2013) that measure cyberbullying victimization and perpetration respectively. The sum score for E-VS range from 5-35, and E-BS from 5-42, and a higher score indicate severity of respective cyberbullying behavior (Lam \& Li, 2013). The Chinese version of CBBS will be used that was translated and validated by our research team.

Secondary Outcomes (4)

Study Arms (2)

Building Respectful Online Space (BROS)

EXPERIMENTAL

The intervention group participants will receive the BROS intervention across three sessions, depending on the school schedule, presented in a hybrid mode. The sessions focus on integrating psychoeducation, behavioural-specific cognitions, serious games, music, and reflection, as a means against cyberbullying. The content includes knowledge related to cyberbullying and online safety, cyberbullying coping skills, relationship skills, emotion management, and empathy towards victims through classroom sessions, short videos, serious games, and online musical therapy.

Behavioral: Building Respectful Online Space (BROS)

Healthy diet education program

PLACEBO COMPARATOR

For the control group participants, an alternative intervention (a healthy diet education program) with content unrelated to cyberbullying prevention will be given. The control group participants will receive the alternative intervention across three sessions. The content is based on recommendations from the Centre for Health Protection, the Government of the Hong Kong Special Administrative Region (CHP, 2024) on healthy eating pyramids, emotional eating, healthy weight management, and nutritional requirements for adolescents.

Behavioral: Healthy diet education program
