High School Anti-Bullying Interventions: An Evaluation of Curriculum Approaches and the Method Of Shared Concern in Four Hong Kong International Schools

Abstract

The challenge for high schools to adopt effective measures to reduce bullying has been underscored by international media coverage highlighting the consequences of school bullying. Despite whole-school anti-bullying programs being accepted as the best evidence-based approaches to intervention, research continues to yield ambiguous findings, and only a limited number of studies have been conducted in secondary schools to systematically evaluate the components of this approach. The aim of this study was to investigate the effectiveness of anti-bullying interventions in four international secondary schools in Hong Kong. Schools were randomly assigned to: (a) a whole-school intervention, (b) a curriculum and Shared Concern intervention at Year 7, (c) a Shared Concern intervention at Year 7 and (d) a control school. Year 7 students in the four schools anonymously completed a bullying questionnaire at the beginning (N = 545) and end of the school year (N = 549). A highly significant main effect for schools was found between pre-test and post-test composite bullying scores (F = 7.70, p < .001). Results showed the most significant reductions occurred when a whole-school intervention was used (F = 10.73, p < .001). The research provides strong support for use of whole-school preventative/management interventions and the effective components of this approach are discussed.
