Abstract
There is increasing concern about the level of violence within mental healthcare settings. In this article I review what is known on this subject, discuss the relationship between mental disorder and violence and summarise the different ways to prevent and manage violence. When planning strategies to prevent violence in such settings it is important to consider not only patient risk factors but also risk factors in the environment. Staff need to have all the possible techniques for managing violent behaviour available to them in order to weigh up the risks and benefits for any specific patient in any particular situation.
