Abstract
Background: The goal of the present study is to analyze the prevalence of bidirectional psychological and physical aggression in intimate partner relationships using the Conflict Tactics Scale (CTS-2), and to determine the influence of the variables age and relationship duration. Method: The participants were 3,578 heterosexual couples from the Region of Madrid. Results: Bidirectional aggression was the most frequent pattern in the dyadic types of aggression examined; we analyzed the prevalences of mutual psychological (46%) and physical aggression (4%), reciprocal psychological (41%) and physical aggression (3%), and bidirectional psychological (80%) and physical aggression (25%). The variables age and relationship duration were significant predictors of bidirectional physical and psychological aggression. Younger couples and couples with less than a one-year relationship duration assaulted each other the most.
