Are the high rates of psychosis found among prisoners real, or do they reflect prisoner drug abuse or unrepresentative surveys? They are real, according to Brugha et al. (p. 774). National samples totaling 13,250 adults in British households and prisons were screened for psychosis, and a diagnostic interview was administered to those with positive results. The prevalence of psychosis was more than 10 times higher among the prisoners than among the community subjects, 52 per 1,000 versus 4.5 per 1,000. The difference could not be explained by the prisoners’ lower socioeconomic status or age and was minimally related to alcohol and drugs. Psychotic symptoms were similar in the two groups, and the rates of antipsychotic medication in the community and in male prisoners were the same (34%). Fewer prisoners had seen primary care physicians about mental health problems during the previous year, however, suggesting a need for greater recognition and treatment for these prisoners.
