School-based violence prevention programs effectively reduce aggressive behavior in children. These programs show lasting positive effects on behavior, even a year later, benefiting various age groups.

Area of Science:

  • Child Psychology
  • Criminology
  • Educational Psychology

Background:

  • Early aggressive behavior is a significant predictor of future violence and criminal activity.
  • Despite extensive school-based violence prevention efforts, their effectiveness for aggressive children remains debated.

Purpose of the Study:

  • To evaluate the impact of school-based violence prevention programs on children identified as aggressive or at risk.
  • To synthesize evidence on the effectiveness of interventions aimed at reducing aggression, violence, bullying, conflict, or anger in school settings.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials.
  • Searched multiple databases (CENTRAL, Cochrane, MEDLINE, EMBASE) and contacted experts for relevant studies.
  • Included trials with randomized assignment, concurrent outcome data, school-aged children exhibiting or at risk of aggression, and interventions targeting aggression-related behaviors.

Main Results:

  • Aggressive behavior was significantly reduced immediately post-intervention (SMD = -0.41) and maintained at 12-month follow-up (SMD = -0.40).
  • School disciplinary actions decreased post-intervention (SMD = -0.48), but this effect was not sustained.
  • Interventions focusing on social skills were more effective than those teaching non-response skills; benefits were consistent across primary/secondary schools and mixed/boys-only groups.

Conclusions:

  • School-based secondary prevention programs show significant positive effects on reducing aggressive behavior in children.
  • Benefits are evident in both primary and secondary school settings, and in mixed-sex and boys-only groups.
  • Further research is needed to confirm long-term effects on violent injuries and sustained behavioral improvements beyond 12 months.
