As intimate partner violence (IPV) often remains unknown to police, bystanders can play a crucial role in prevention and further escalation of IPV. However, little is known about what brings them into action by reporting incidents of IPV to authorities. As such, we use statements of bystanders who filed reports about IPV incidents to an official domestic violence agency in the Netherlands (N = 78), to investigate the reasoning and motivations for reporting their suspicions. Results show that the reasons for bystanders to report IPV differ depending on the relational dynamics between partners. In situations perceived as intimate terrorism, involving a hierarchical abusive relationship between a man offender and a woman victim, bystanders primarily reported when previous helping initiatives proved inefficient, and they did so to prevent further harm, often particularly in relation to the woman victim. In situations perceived as situational couple violence, involving a symmetrical abusive relationship, bystanders primarily reported when escalation appeared, and they did so to prevent further harm to involved children. We conclude that bystanders report IPV incidents when the need for help is clear, and their motivation for acting concerns the well-being of victims. Our findings add to the growing body of evidence about real-life bystander intervention in emergencies and highlight the need for understanding intervention as context-specific in order to design effective intervention initiatives.
