The current chapter aims to provide an outline of recommended content for violence/aggression therapy. It aims to provide a review rather than detailed analysis of the core approaches required for effective treatment. Points will be illustrated where possible using elements of a recently developed and revised violence treatment programme (Life Minus Violence: see Ireland 2007, and Chapter 4, this volume). Focus will be on the concept of habitual aggression (i.e. repeated aggression), since it is habitual aggressors who are most likely to come into contact with professional services for aggression management.
