Sexual assault on college campuses has become a major concern. A common response has been to provide bystander intervention training, which research shows may provide short-term attitude change without reducing the number of assaults. Current curricula and research may neglect the very factors that could play a part in students' desire and ability to intervene, one of which may be moral motivations. For this qualitative study, we interviewed students (n = 38) who identified as having been bystanders to a 'sketchy sexual situation' to understand, from a moral perspective, their decisions to intervene or not. In exploring narratives, we used Moral Foundation Theory to categorize the moral reasoning of participants and explore the voices and motivations that adhere to these categories. Through a thematic/discourse analysis we identified additional discourses. Implications for changes to bystander intervention training are discussed.
