Summary

This study tested a program called BullyDown, which sends text messages to middle school students over 8 weeks to help prevent bullying. The messages teach social and emotional skills. 138 students took part, and the study checked if the program was easy to use and if students liked it. It did not measure whether bullying actually went down.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
text-message bullying prevention program (BullyDown)
What this could lead to
If it works, this could provide a scalable, low-cost way to prevent bullying among middle school students, even when learning remotely.
What could go wrong
This is a small, completed feasibility study with 138 participants. It only measured whether the program was acceptable and could retain participants, not whether it actually reduces bullying.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
