Area of Science:

  • Child Psychology
  • Educational Interventions
  • Public Health

Background:

  • Adolescent aggression poses significant public health challenges.
  • Effective violence prevention strategies are crucial for school-aged children.
  • Existing curricula vary in their impact on aggressive behaviors and related skills.

Purpose of the Study:

  • To assess the impact of a violence prevention curriculum, with and without peer leaders, on 6th graders' aggressive behaviors.
  • To evaluate changes in knowledge, conflict resolution skills, self-efficacy, and attitudes towards violence.
  • To determine the sustained effects of the intervention over time.

Main Methods:

  • A quasi-experimental design comparing two intervention groups (curriculum alone, curriculum with peer leaders) and a control group.

  • Involved 223 6th-grade students across ten classes in four middle schools.
  • Utilized pre- and post-intervention assessments, with a 3-month follow-up evaluation.

    • Main Results:

    • The curriculum significantly increased knowledge of violence and conflict resolution skills for all intervention participants.
    • A negative shift in attitudes towards violent responses was observed, particularly in the peer leader group.
    • Reductions in aggressive behaviors were limited, primarily observed in boys and only in specific intervention classes; effects were not sustained.
    • No significant impact was found on self-efficacy or attitudes towards violence reduction skills.

    Conclusions:

    • Violence prevention requires continuous, comprehensive interventions rather than short-term programs.
    • Careful selection and training of peer leaders are essential for maximizing intervention effectiveness.
    • Future research should prioritize aggressive behaviors as a primary outcome measure, alongside knowledge and skills acquisition.
