According to the clinical impressions of a number of authors and mental health professionals, an increased risk of violence is associated with the presence of hallucinations and in particular command hallucinations. In contrast to this, some empirical studies have reported that there is no evidence of such a relationship. The present review examines the role of hallucinations in violence toward others. Possible empirical evidence for a violence-escalating interaction between delusions and hallucinations is also analyzed. Among the main findings were: There appears to be no evidence that auditory command hallucinations are dangerous per se. However, there is some evidence that voices ordering acts of violence toward others may increase compliance and thereby be conducive to violent behavior. Finally, the evidence for or against the existence of a possible violence-escalating interaction between delusions and hallucinations is inconclusive.

The main scope of this article is to delineate some findings from a review of the literature concerning the possible impact of delusions on violence toward others by psychiatric patients. According to this review, studies on a possible association between delusions and increased risk of violence are scarce, but steadily growing, and have shown some interesting results. However, since delusions are also common in nonviolent psychiatric patients, there is emerging evidence that our attention should be directed to specific hallmarks of delusions that indicate an increased risk of violence.
