A profile of mentally disordered offenders admitted to inpatient psychiatric services in the United States

This research note presents data about mentally disordered offenders (MDOs) treated in inpatient psychiatric services. Data are derived from 1980 admission surveys by the Survey and Reports Branch, National Institute of Mental Health (NIMH). These data report for the first time inpatient services provided to MDOs by non-Federal general and private hospitals. A total of 31,773 MDOs were admitted, with 85% going to state and county mental hospitals. The largest group, including admissions for evaluation, was ISTs (58%), followed by mentally disordered prisoners (32%), NGRIs (8%), and MDSOs (3%). Women and whites tended to be overrepresented among MDOs as compared to prison and jail inmates. Clear diagnostic differences by legal status were found, with schizophrenia predominant among NGRIs (81%) and alcohol and drug abuse disorders more frequent among ISTs. Overall, state and county hospitals in both 1967 and 1980 were the primary locus of care for mentally disordered offenders.
