This paper reviews data associated to violence in the context of intimate couples attending a Community Mental Health Centre. It is concluded that violence affects a high percentage of this population. Both females and males reported a lower level of aggression for themselves than their partner attributed to them; no differences were found in psychological violence among males and females, but differences in physical violence reach statistical significance. Mechanisms underlying violence are reviewed and a Biopsychosocial Model of Violence is presented. Practical recommendations are put forward and suggestions for further research are made (typologies, differences between explicit and implicit demands of patients, violence as a continuum or as categorical differences between violent and non-violent behaviors…).
