This document provides researchers, prevention specialists, and health educators with tools to measure a range of bullying experiences: bully perpetration, bully victimization, bully-victim experiences, and bystander experiences. Some researchers continue to examine the risk and protective factors associated with bullying experiences. Others are working to design, implement, and evaluate bully prevention interventions aimed at reducing bully victimization and perpetration, as well as increasing prosocial bystander involvement in bullying situations. The ability to measure bullying experiences broadly and completely is crucial to the success of these activities. This document represents a starting point from which researchers can consider a set of psychometrically sound measures for assessing self-reported incidence and prevalence of a variety of bullying experiences.
