WITS Research and Evaluation
WITS Programs Evaluations
Evaluation #1: 2000-2003
Examined data from 11 program and six control schools on children's ratings of relational and physical victimization and found that:
- Relational victimization decreased in all program schools and low-poverty control schools but increased in high-poverty control schools
- Physical victimization decreased in all program schools and low-poverty control schools but increased in high-poverty control schools
Evaluation #2: 2006-2008
Examined data from six program and five control schools on children's ratings of physical and relational victimization and teacher's ratings of social responsibility among students. It found that:
- The rate of decline in both physical and relational victimization was greater in program than control schools
- Teachers of program school children reported higher average levels of social responsibility at each time point, compared to control schools
