In Canada, three universities recently ran a program to train female students to avoid sexual assault while in college. The two-year program was available at universities in Calgary, Alberta, and Windsor and Guelph in Ontario, Canada. The program involved students in their first year at the schools. The students spent 12 hours learning how to judge risks, deal with emotions, and use self-defense. The program taught students to be especially on guard at parties and other high-risk campus social events. The training taught students to attend such events together. If separated, they should check on each other periodically. They should also take extra care in their use of alcohol. At least half of the sexual assaults among college women involve drinking. About 450 students received the training. A group of about the same size received only written information and a brief meeting with the trainers. The group that received the 12 hours of training saw an almost 50 percent drop in risk of rape. The study was designed for women while effective interventions that target men’s behavior are also needed.
