Examination of situations in which bystanders missed intervention opportunities to prevent sexual assault can advance our understanding of how bystanders can prevent sexual assault. The present study utilized an incident-specific approach based on reports from 427 female sexual assault victims (ages 18-25 years) recruited via Mechanical Turk. Results indicate that bystanders had an opportunity to intervene before 23% of sexual assaults, alcohol use in settings with bystanders was widespread (by perpetrators, victims, and bystanders), and several factors were more common in situations involving missed intervention opportunity. Findings provide useful information for continued development of bystander training and new directions in bystander research.
