This article explores the increased role of state-operated public psychiatr
ic hospitals in treating forensic patients. Patients with a forensic legal
status have a mental illness and are involved with the criminal justice sys
tem. Using data from Missouri's forensic system, the article compares the c
haracteristics of voluntary hospital patients with those of the largest hos
pitalized group of forensic patients-there found not guilty by reason of in
sanity (NGRI). Overall, NGRI patients tended to be higher functioning, less
likely to have committed assaultive acts, and more likely to have substanc
e abuse and personality disorder diagnoses. The article explores the treatm
ent needs of forensic patients who reside in public psychiatric hospitals a
nd discusses the effect of the strong presence of forensic patients in publ
ic psychiatric hospitals on social work practice, including clinical work w
ith forensic patients, social work administration, and social work advocacy
.
