A Multisite Study of Community Treatment Programs for Mentally Ill Offenders With Major Mental Disorders: Design, Measures, and the Forensic Sample

This article presents reasons for undertaking "The Comparative Study of the Prevention of Crime and Violence by Mentally Ill Persons" and reasons for decisions regarding the study design and choice of measures. A brief portrait of the forensic patients that have been recruited is also presented. Community treatment programs could offer long-term cost-effective care for offenders with major mental disorders (MMDs). The study aims to identify the necessary ingredients of an effective program. Sites are selected in four countries where identification of most, if not all, persons with MMD who commit crimes within the catchment area was possible. Within each site, two samples of patients with MMD are recruited, one from a forensic hospital and one from a general psychiatric hospital. Assessments are completed prior to discharge. Participants are followed during a 5-year period. Comparisons of the forensic patients recruited in the four sites indicate many more similarities than differences.
