Summary
Researchers developed and validated survey tools to measure the impact of bystander violence prevention programs in high schools. These instruments assess factors like readiness, intentions, and empathy, aiding program evaluation.
Area of Science:
- Public Health
- Psychology
- Sociology
Background:
- Bystander-focused violence prevention is crucial in high school settings.
- Effective measurement tools are needed to evaluate these programs.
- Existing instruments may not adequately capture key outcomes.
Purpose of the Study:
- To describe the adaptation and development of survey instruments.
- To assess the psychometric properties of these new measures.
- To evaluate outcomes of bystander-focused violence prevention efforts.
Main Methods:
- Data collected from 3,172 high school students across 25 schools.
- Multilevel exploratory and confirmatory factor analyses were conducted.
- Psychometric properties including reliability and internal consistency were examined.
Main Results:
- Survey measures demonstrated acceptable fit indices in factor analyses.
- Most measures and subscales showed adequate reliability.
- Some measures had less than ideal internal consistency due to limited items.
Conclusions:
- The developed measures offer foundational tools for research and program evaluation.
- Further measurement refinement is recommended.
- These instruments can aid in understanding and improving bystander interventions.

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...
