Bystander intervention is considered a promising practice for preventing sexual violence on college campuses. UNC-CH first implemented bystander intervention in fall 2010 with our first One Act training, and have been growing the program since then, training over 2130+ students in One Act or One Act for Greeks since its inception.
Because of our commitment to implementing programs using the best available evidence possible, Student Wellness staff collect data about the effectiveness of One Act bystander intervention to make sure that what we’re doing is working! We’re delighted to share that data from the first two years of the program that we’ve previously shared here on the blog was published in the May 2015 issue of the Journal of Interpersonal Violence.
So what else have we learned?
- About one quarter of students attending One Act trainings (excludes One Act for Greeks*) in 2012-2015 identify that they have experienced sexual violence, interpersonal violence, or stalking in their lifetime.
- On average, 85% of One Act participants (excludes One Act for Greeks) in 2012-2015 know someone who has experienced sexual violence, interpersonal violence, or stalking.
- 100% of participants in both One Act and One Act for Greeks during the 2014-2015 academic year who completed our 1 – week post-test said that they are likely or very likely to intervene if a friend says that forcing someone to have sex is okay.
