Bystander behaviour in sexual violence has been investigated widely in the Global North, and especially in the US context. However, there has been a call for qualitative approaches to increase understanding of sexual violence and bystander behaviour in a wider range of countries. In the present study, we conducted focus group research to investigate sexual violence in the only public university in Guatemala, Central America. In total, 18 students (5 men) participated in one of six online focus group sessions. We employed an inductive thematic analysis, and constructed four main themes: Forms, dynamics, and consequences violence to the targets and the bystanders; Barriers to bystander action; Facilitators to bystander action; and Past bystander intervention actions. We discuss the results with a reference to the context in Guatemala, and suggest intervention approaches based for the future.
