NCT ID NCT07191782
First seen Jun 25, 2026 · Last updated Jul 23, 2026 · Updated 3 times
Summary
This study tests whether a program called PRAISE, led by school staff, can reduce bullying and aggression in 3rd-5th graders. Over 1,000 students will participate. The program teaches social and emotional skills to help kids handle peer conflicts without aggression. Researchers will measure changes in aggression, victimization, and bystander behavior.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PRAISE program (behavioral intervention)
- What this could lead to
- If it works, this could provide an effective, scalable way for schools to reduce bullying and aggression among elementary students.
- What could go wrong
- This is a large trial but still early-stage for this adapted model. Results may vary by school, and the program may not work as well when led by school staff instead of research staff.
