Thanks to studies conducted over the past decades, it has been underlined how harmful consumption of alcohol or other substances and intimate partner violence are intertwined. What has been recognized is, in particular, how the relation between these two factors may be represented as a vicious cycle in which each of them influences the other, reciprocally. The aim of this paper is to offer an overview, firstly, about the global and European scenario of the spread of these constructs, delineating, then, the main explanation models that theorize their connection and those risk factors associated with the environmental settings which may play a significant role.
