q3 · i? · causal · r?
A randomized controlled trial of almost 1,000 third-grade students in 10 elementary schools in one large Florida school district compared the Too Good for Violence curriculum with classes using no prevention curriculum. The WWC confirmed "statistically significant differences favoring the intervention group" on the teacher behavior checklist.
"Hall and Bacon (2005) reported, and the WWC confirmed, statistically significant differences favoring the intervention group on the teacher checklist of elementary school students’ behavior (total score) 20 weeks after the end of the program."
