Bystander Intervention in Intimate Partner Violence: A Scoping Review of Experiences and Outcomes

Abstract

Governments across the globe are increasingly implementing policies that encourage bystanders to prevent intimate partner violence (IPV) by intervening in violent or potentially violent situations. While a wealth of research examines the most effective mechanisms for increasing potential bystanders’ feelings of self-efficacy and rates of intervention, there is significantly less evidence demonstrating how effective bystander intervention is at preventing or interrupting IPV. This article thus presents a scoping review of the literature examining the experiences and outcomes of bystander intervention in IPV. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses, extension for Scoping Reviews guidelines, six databases were searched for relevant peer-reviewed studies published in English between 2001 and 2021. A total of 13 articles were ultimately included in the review. The review highlights that although current knowledge on the topic is highly limited, the combined findings of the studies indicate that immediate responses to bystander intervention are heavily context dependent: victims (and perpetrators) tend to react differently to bystander intervention depending on the type of intervention, the type of violence being used, and their relationship to the bystander. However, we have little to no understanding of the outcomes of bystander intervention, or how these outcomes might vary across different contexts. We argue that a more comprehensive understanding of the immediate and long-term implications of bystander intervention across different contexts is crucial if we are to maximize the effectiveness and minimize the potential for harm resulting from bystander interventions in IPV.
