The reliability and validity of resident, staff and peer reports of bullying in young offender institutions

Abstract

This research compares resident, peer and staff reports of bullying and victimization in one open facility and one secure facility for young offenders. The prevalence of bullies and victims was higher according to resident reports (self-reports) than according to peer or staff reports. There was significant agreement between residents, peers, and staff in identifying bullies and victims. The majority of bullies and victims identified by peers and/or staff were also identified by self-reports. Making the plausible assumption that bullies and victims tend to be concealed, it is concluded that self-reports (in the context of an individual interview) provide the most reliable and valid information about bullies and victims in young offender institutions. Hence, anti-bullying strategies should be based on self-report data.
