Violent Behavior During Psychiatric Inpatient Treatment in a German Prison Hospital

Area of Science:

• Forensic Psychiatry
• Criminology
• Correctional Healthcare

Background:

• Violent behavior in correctional facilities and psychiatric hospitals is prevalent but under-researched.
• Comorbidity of severe mental disorders, personality disorders, and substance abuse is associated with increased violence risk.

Purpose of the Study:

• To investigate the frequency and characteristics of violent incidents in a prison hospital.
• To identify specific socioeconomic and psychiatric factors associated with violent behavior among prisoners.

Main Methods:

• Retrospective case-control study analyzing data from 210 violent incidents (1997-2006, 2010-2016).
• Comparison of prisoners with violent behavior against a control group (n=210) matched for department and time period.
• Analysis of socioeconomic data and psychiatric diagnoses.

Main Results:

• Schizophrenia diagnosis, non-German nationality, no interpreter use, no children, and no prior convictions were significantly associated with violent behavior.
• No significant differences were found in age or legal status between groups.

Conclusions:

• Specific demographic and clinical factors, including schizophrenia and nationality, are key predictors of violence in this prison hospital population.
• Findings offer practical implications for clinical risk assessment and management within correctional mental health services.
