A great deal of research has been conducted into the risk of violent behavior among people with mental disorders. However, their risk of victimization is a subject that has received little attention. This research bias helps to maintain stereotypes on mental disorders and perpetuate the stigma and social isolation of the people involved. According to the studies reviewed, such people are far more likely to be the victims of violence than the general population, especially during periods when the symptoms are more acute. This theoretical article examines the other side of the relationship between mental disorder and violence, focusing on the epidemiology of the problem, the most significant risk factors (prior victimization, drug abuse, social exclusion, comorbidity/symptom severity and development disorders) and some common forms of victimization (suicide, domestic violence, sexual violence, bullying and child abuse). The aim is to contribute to a better understanding of the risks of victimization in these people, which may lead to more appropriate prevention and treatment strategies.
