The Application of Bystander Intervention Scripts: Implications for Guardianship in Action

Area of Science:

• Adolescent psychology
• Criminology
• Public health

Background:

• High rates of adolescent interpersonal victimization and perpetration necessitate violence prevention strategies.
• Bystander intervention (BI) training aims to equip students with skills to prevent or stop violence.
• Existing research links BI training to 'guardianship in action' scripts.

Purpose of the Study:

• To test if participation in Green Dot (GD) BI training influences adolescents' underlying ability to intervene.
• To model the difficulty of various BI behaviors using item response theory.
• To estimate the effect of GD training on students' intervention ability.

Main Methods:

• Utilized four years of survey data from 2,374-3,443 high school students.
• Applied item response theory to determine the difficulty of different BI behaviors.
• Employed multivariate ordinary least squares regression to assess GD training's impact.

Main Results:

• Item response theory revealed that BI behaviors vary in difficulty.
• GD training was found to increase students' underlying ability to intervene each year.
• The positive effect of GD training on intervention ability was consistent across the four years.

Conclusions:

• BI training, such as GD, effectively enhances adolescents' capacity for intervention.
• Training programs should acknowledge and address the varying difficulty levels of BI behaviors for optimal effectiveness.
• This research supports the integration of BI training into school violence prevention efforts.
