High School Strategy Study Published
Confirms Impact of Green Dot Strategy

A five-year, independent study confirms the effectiveness of the Green Dot Strategy for High Schools with significant reductions in rates of interpersonal violence.

“Results from this 5-year RCT indicate that this bystander program to reduce violence, adapted for high school students, was associated with 120 fewer sexually violent events in Y3 and 88 in Y4 when the intervention was fully implemented,” concludes the study’s authors. “From secondary analyses, the intervention was effective in reducing the student-level violence perpetration rates by 17%-21% (p<0.01) in Y3 and Y4.”


“At the end of the study, we see numbers like 300 experiences of violence dropping to 157 instances in a year,” says Dr. Dorothy J. Edwards, founder and president of Green Dot etc., Inc., and author of the high school curriculum. “Not only did they see reductions in sexual assault, these reductions applied to both perpetration and victimization, and they saw similar results for sexual harassment, dating violence, and stalking.” For Edwards, the true impact is beyond statistics: “When you look at those numbers, you see that 143 students—girls and boys—did not get assaulted; that somebody’s child or sibling or best friend who will never go through this experience. That’s the ultimate human benefit. That’s the importance of this study and what it means to us.”

The study evaluated the Green Dot strategy in 26 high schools in Kentucky over 5 years and included 89,707 student surveys. In the study, 13 schools implemented the Green Dot strategy while 13 schools, as a control group, did not. The study compared rates of violence over the five-year period both within the 13 implementing schools and between the implementing and control groups.

The study examined frequency of self-reported sexual violence perpetration and victimization. “Because different types of violence frequently co-occur,” notes the study, “intervention effects on sexual harassment, stalking, and dating violence were also measured for both victimization and perpetration.”

The study, led by Dr. Ann L. Coker at the University of Kentucky and funded by the Centers for Disease Control and Prevention, was published in the March edition of the American Journal of Preventive Medicine. Read the full study »
