The clinical presentation of command hallucinations in a forensic population.

In a forensic population, patients with command hallucinations (N = 25) were compared to two groups of psychotic patients: those with noncommand hallucinations (N = 24) and those without hallucinations (N = 16). The three groups did not differ in overall impairment as measured by the Global Assessment Scale and the Social Behavior Rating Schedule. However, the group with command hallucinations differed in the content of their hallucinations (more aggression, dependency, and self-punishment themes), and nearly one-half did not report or denied their command hallucinations to the assessment team. Many patients (N = 11, 44%) reported that they frequently responded to hallucinatory commands with unquestioning obedience.
