HOMELESS MENTALLY DISORDERED OFFENDERS AND VIOLENT CRIMES - PRELIMINARY RESEARCH FINDINGS

This study examines the prevalence of homelessness in a cross-sectional sample of 150 patients retained in a maximum-security hospital for mentally disordered offenders in New York City. The homeless mentally ill comprise only 2% of the city's mentally ill population, yet they account for 50% of the admissions to this forensic facility from the community. Compared to population base rate estimates, forensic patients are homeless at 25 times the rate found in the rest of the city's mentally disordered population and are 50 times more likely to be homeless than the general population. Further, there is a significant association between homelessness at the time of the instant offense and charges for violent crimes, after controlling for age, sex, race, and diagnosis. These data suggest that homelessness greatly increases the risk that mentally disordered persons will be forensically hospitalized and is closely associated with indictments for violent criminal behavior. Alternative explanations for these findings are discussed, emphasizing risk, vulnerability, and criminalization perspectives. © 1991 Plenum Publishing Corporation.
