Official title

Translating an In-Person Brief, Bystander Bullying Intervention (STAC) to a Technology-Based - Phase II

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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 school students for less cost. The feasibility of delivering the effective STAC bullying intervention through a mobile web app will be tested using focus groups with middle school students and development and usability testing and the efficacy of the program will be tested using a randomized controlled trial.
