Summary

Given the limited impact of existing school-based interventions and the time associated with implementing them during school time, more efficient and effective intervention methods are needed. Programs that can be delivered to middle school youth irrespective of whether they are attending school physically or virtually may be especially relevant as school boundaries become more fluid. BullyDown addresses this critical need by providing a scalable program that could be quickly and cost-effectively disseminated nationally.

Eligibility Criteria

Participants will: be enrolled in one of our partner schools, be in middle school (i.e., 7th or 8th grade) or between the ages of 12-14 years of age, be English-speaking, own their own cell phone, intend to have the same cell phone number for at least 3 months (this may or may not apply, depending on the number of youth who meet this criterion), and provide informed written assent. Non-English speakers and youth who do not have the reading ability to complete the screener are not eligible. Youth recruited from schools will also be required to have parental permission.
