Psychiatric illness and comorbidity among adult male jail detainees in drug treatment.

The prevalence of psychiatric disorders was examined in a sample of 204 pretrial jail detainees receiving standard drug treatment. More than half of the sample had at least one lifetime DSM-III-R axis I diagnosis, and the lifetime rates of serious mental illness were higher than reported prevalence rates for arrestees in general jail populations. Detainees with comorbid disorders were more likely than others to have more than one co-occurring psychiatric disorder, to have been arrested for property crimes, and to be dependent on alcohol, marijuana, or PCP. The findings argue for the expansion of integrated treatment services within criminal justice drug treatment settings.
