This article presents a systematic review and meta-analysis of the effectiveness of school-bullying prevention programs, updating earlier research from 2009.


A comprehensive and extensive systematic review and meta-analysis of the effectiveness of bullying prevention programs is presented. This report updates earlier research conducted by Farrington and Ttofi (2009). Systematic searches of online databases were conducted for primary studies published from 2009 to December 2016. Searches were also conducted for unpublished reports. To be included in the systematic review, primary studies must: (1) describe an evaluation of a school-based anti-bullying program; (2) utilize an appropriate operational definition of school-bullying; (3) measure school-bullying perpetration and/or victimization behaviors using quantitative measures; and (4) use an experimental or quasi-experimental design with adequate control group.
