Summary

This study follows 600 mentally ill offenders in Italy and California over three years to compare two very different treatment systems. Italy uses community-based care, while California relies on long-term hospital stays. Researchers will track violence, recovery, and functioning to see which model leads to better outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could reveal which aspects of forensic mental health care (community-based vs. hospital-based) work best, guiding improvements in treatment and reducing repeat offenses.
What could go wrong
This is an observational study, not a controlled experiment, so differences in outcomes may be due to factors other than the treatment model. Results may not apply to other regions or populations.

Who is studied

The study population consists of mentally ill offenders, with total or partial mental infirmity, entering Italian forensic care settings (Group I: REMS or non-custodial forensic settings) or Californian hospital forensic facilities (Group C) for the first time during the enrolment period. The Italian sample will be recruited through the national network of Departments of Mental Health (DSM) and forensic structures (REMS and community forensic services) participating in the study, coordinated through the Regional Single Contact Points (P.U.R.) established under the 2022 Unified Conference Agreement no. 188/CU. The Californian sample will be recruited through the Department of State Hospitals (DSH) network under the coordination of Prof. Katherine Warburton.
