The most recent research on psychosis and violence shows a significant positive association between both, although the risk of violence on psychosis is much lower than the risk of violence in substance abuse or personality disorders; and, in a general way, the predicting fac- tors for violence in patients are the same than in individuals without mental disorders. Psychiatrists and clinical or forensic psycholo- gists frequently have to predict violent behaviour. Since the 90s, instruments that evaluate the risk of violence have been developed, based on statistical methods to improve the efficacy of the evaluation. The best known are Psychology Checklist-Revised, Historical Risk Management-20 and Violence Risk Appraisal Guide. Several investigators consider these instruments essential for more rigorous predictions, as they are superior to clinical methods; other investigators state that the main advantage of these instruments is the fact that they sumarise the most recent advances in these areas, so that clinicians can make evidence based decisions.
