First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two versions of a school program called Mental Health Enhanced Positive Behavioral Interventions and Supports (PBIS-MH) to see if it could reduce aggression in middle school students. About 4,840 students and their teachers from multiple schools took part. The program added mental health support and addressed racial/ethnic discrimination to improve school climate and reduce violent behavior.
