A recent directory of facilities providing treatment for mentally disordered offenders in the United States listed 189 different agencies that provide services to adult and/or juvenile offenders (Directory of Programs and Facilities, 1986). When one considers that these 189 agencies are distributed across 50 different states, plus the federal system, it is easy to understand that describing “forensic treatment” in the United States is no easy task. Virtually all of the agencies providing treatment to forensic patients are publicly operated hospitals, clinics, or detention facilities of one type or another, Thus, potentially different laws, organizational structures, economic support systems, theoretical preferences, administrative policies, and attitudes toward “forensic patients” may be encountered each time one of the political boundaries is crossed. Forensic programs may vary on the most fundamental of issues, including what range of services will be provided (e.g., pre-trial evaluations versus mental health treatment) or the legal identification of prescribed treatment populations (e.g., eligible treatment groups). Some states, such as Michigan, Virginia, and Alabama provide extensive pre-trial evaluation services for the state’s courts, devoting facilities and staff resources for defendants to be examined regarding competency to stand trial, mental state at the time of offense (insanity defense evaluations), pre-sentencing assessments, and so forth. Other states, such as Florida, make no provisions for such services through the public mental health departments and all pre-trial evaluations are conducted by private mental health practitioners. Some states, including Massachusetts and Florida, identify special offender groups as target treatment populations (e.g., mentally disordered sex offenders), while such legal classifications are nonexistent in many other states’ statutes. In some states, mental health services are provided to offender populations by more than one state agency, including a mental health department or a department of corrections; in other states, convicted offenders may receive treatment services either by transfer to the Department of Mental Health or by mental health department staff who physically reside in satellite units located on the grounds of correctional institutions.
