Green Dot Across the Bluegrass: Evaluation of a Primary Prevention Intervention
The purpose of this study is to evaluate the statewide application of Green Dot among high schools students.
We hypothesize that students in high schools with Green Dot will over time report lower rates of sexual violence (SV) compared with students in comparable high schools randomized not to have Green Dot.
This reduction in sexual violence will be mediated through a reduction in social norms supporting sexual violence (measured with violence acceptance scales) and an increase in bystander behaviors.

Gedetailleerde beschrijving
"Green Dot" is a bystander intervention program that empowers students to actively question peer support for sexual violence (SV) and become change agents who play a significant role in preventing sexual violence.
The purpose of this study is to evaluate the statewide application of Green Dot among high schools students.
We hypothesize that students in high schools with Green Dot will over time report lower rates of SV compared with students in comparable high schools randomized not to have Green Dot.
A high school based controlled intervention trial is being used to test the efficacy of Green Dot.
Both panel and cohort survey methods will be used to provide baseline and prospective data on student's attitudes supporting SV, bystander behaviors and violence victimization and perpetration.
In 13 Kentucky regions, 2 demographically comparable high schools were recruited to participate in Green Dot intervention either as the intervention or control site.
Schools were randomly assigned to the intervention.
Study Population includes all students in participating high schools invited to complete anonymous panel surveys beginning spring 2010 through 2014.
This state-wide, population-based, multi-site controlled intervention trial provides an empirical test of a promising intervention, which, if proven effective, could result in the primary prevention of SV and a reduction in the health and academic consequences of SV.

Average Number of Sexual Assault Events Used (Perpetrated) Per School.
Tijdsspanne: up to 5 years follow up from baseline intervention

Students self report of sexual assault perpetration averaged at the school level and adjusted for baseline and number of students.
Adjustments were made by including baseline measure and number of students as a covariate in the model.
Data will be collected at baseline and annually for 4 years.

Change in Violence Acceptance
Tijdsspanne: Data will be collected at baseline and annually for 4 years.

Illinois Rape Myth Acceptance Scale measure students' beliefs about rape which may indicate social norms supporting sexual violence. The scale consists of 22 questions scored 1 -5. Were 1 is "strongly agree" and 5 is "strongly disagree". The higher the cumulative score, the more likely the participant is to accept rape myths. 5-item Acceptance of General Dating Violence Scale was used to measure norms supporting dating violence. Scores will range from 1-6, were the higher the score the more likely the participant was to reject dating violence as normal. |
Data will be collected at baseline and annually for 4 years.

Increase in Bystanding Behaviors
Tijdsspanne: Data will be collected at baseline and annually for 4 years.
|
7 item survey measuring self-reports of students actively engaging their peers in behaviors that may prevent violence. Response options: 0 times, 1-2 times, 3-5 times, 6-9 times, 10 or more times, didn't see or hear someone doing this Above items repeated to measure student observing others doing these behaviors. Data will be presented as the total number of interventions were the bigger the number the more likely the bystander was to intervene on behalf of the victim. |
Data will be collected at baseline and annually for 4 years.
