In 2004, a set of validated guidelines for school bullying prevention and management was released by the Child Health Promotion Research Centre in Australia to guide schools' action to prevent and manage bullying behaviours. At this time little was known about cyber and other forms of covert bullying behaviours. These guidelines were updated in 2010 to include current research that provides a greater understanding of all forms of bullying behaviour. This article describes a summary of the current empirical evidence used to update these guidelines particularly related to relatively new and emergent forms of bullying, such as cyberbullying. Meta-analyses and reviews that assessed the effectiveness of school-based bullying interventions were examined to inform the relevance of the previously validated guidelines and to identify potential intervention strategies to reduce cyberbullying. This review confirmed the importance of a systematic whole-school approach to effectively prevent and manage all forms of bullying behaviours in schools (including cyberbullying) and the need to strengthen capacity supports to enable schools to put evidence into informed practice.
