Study Details
Setting
One large school district in Florida serving students from urban, suburban, and rural regions.
Study sample
The study included 999 third-grade students from 10 elementary schools. Of the sample, 48% were females, 20% received exceptional education services, 17% received limited English proficiency services, 44% were Caucasian, 12.5% African-American, 36% Hispanic, and 7.5% “multicultural or other race.” About 54% of the students in the sample were eligible for participation in the free or reduced lunch program.
Intervention Group
The program was implemented during the first quarter of the school year. The program instructors in the intervention group delivered seven lesson units—one a week—over a seven-week period, with each lesson averaging 45 minutes in length.
Comparison Group
Students in the comparison group did not participate in the Too Good for Violence program. In addition, the comparison schools were asked to refrain from delivering any major prevention curriculum or program until the fourth quarter.
Outcome descriptions
The two measures, the Student Protective Factor Survey Questionnaire and the Teacher Checklist of Student Behaviors, were administered immediately after the intervention and again 20 weeks later. (See Appendices A2.1 and A2.2.)
Support for implementation
The program was delivered by program instructors (off-site educators). So no teacher training was conducted.

An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
