Sponsor's own description

School interventions to reduce bullying can be effective but also require substantial time and resources. Online technologies have the potential to deliver effective bullying interventions to a large number of middle schools for less cost. The feasibility of delivering the effective STAC bullying intervention through a mobile web app will be tested using a needs analysis with school administrators, focus groups with middle school students, and development and usability testing of a prototype.
