Bystander Attitudes to Prevent Sexual Assault: A Study of College Students in the United States, Japan, India, Vietnam, and China.

College women are at a high risk of sexual assault. Although programs that aim to change bystander behaviors have been shown to be potentially effective in preventing sexual assault on campuses in the United States, little is known about bystander behaviors outside of the United States. The purpose of this study was to explore and compare factors affecting bystander behaviors regarding sexual assault intervention and prevention among undergraduate students in the United States, Japan, India, Vietnam, and China.
