The Intersection between Criminal Accusations, Victimization, and Mental Disorders: A Canadian Population-Based Study

Area of Science:

• Public Health
• Epidemiology
• Mental Health Research

Background:

• Mental disorders are prevalent in the general population.
• Understanding the intersection of mental health, criminal justice, and victimization is crucial for public health.
• Administrative data offers a valuable resource for population-level health research.

Purpose of the Study:

• To investigate the relationship between diagnosed mental disorders and criminal accusations and victimization.
• To determine the population-level risks associated with mental disorders in relation to criminal justice involvement and victimization.
• To examine the overlap between mental disorders, criminal accusations, and victimization.

Main Methods:

• Utilized administrative data from Manitoba, Canada, covering residents aged 18-64 from 2007-2012.
• Compared rates of criminal accusations and victimization in individuals with diagnosed mental disorders versus those without.
• Calculated adjusted relative risks and used chi-squared tests to analyze the overlap between conditions.

Main Results:

• 24% of the population had a diagnosed mental disorder over the study period.
• Individuals with mental disorders had 2 to 5 times higher adjusted relative risk of criminal accusations and victimization.
• Elevated risks were particularly pronounced for those with psychotic or personality disorders and a history of attempted suicide.

Conclusions:

• Individuals with mental disorders are at significantly elevated risk for both criminal involvement and victimization.
• These findings highlight the need for integrated support systems for multiply-stigmatized individuals.
• Targeted interventions may mitigate risks and improve outcomes for this vulnerable population.
