Bilateral violence
“Bilateral violence is a controversial concept and experts do not agree about its characteristics. It occurs when both partners within a relationship are violent towards each other. Understanding this issue is challenging. Data on intimate partner violence are not always collected to reflect that relationships can be complex and dynamic. Data can also span a wide spectrum of behaviours, from unhealthy conflict (sometimes known as common couple violence) in a relationship to severe physical and psychological abuse (sometimes known as intimate terrorism).”
