Overlap between child protection services and the youth justice system: protocol for a retrospective population-based cohort study using linked administrative data in Manitoba, Canada.

Introduction: Children who have a history of involvement in child protection services (CPS) are over-represented in the youth and adult criminal justice systems. There are significant health and socioeconomic implications for individuals involved in either or both CPS and the justice system. Understanding the 'overlap' between these two systems would provide insight into the health and social needs of this population.

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

Objective: Understand the relationship between criminal accusations, victimization, and mental disorders at a population level using administrative data from Manitoba, Canada.

Method: Residents aged 18 to 64 between April 1, 2007, and March 31, 2012 ( = 793,024) with hospital- and physician-diagnosed mental disorders were compared to those without. Overall and per-person rates of criminal accusations and reported victimization in the 2011/2012 fiscal year were examined.

Prevalence of mental disorders among all justice-involved: A population-level study in Canada.

More than 10 million people are imprisoned around the world, with many more who encounter the justice system. However, most studies examining the mental health burden in the justice system have examined only incarcerated individuals, with few looking at both criminal offending and victimization at the population-level. This study aimed to describe the population-level prevalence of mental disorders among the entirety of justice-involved individuals in a Canadian sample.

Risk and associated factors for a future schizophrenia diagnosis after an index diagnosis of unspecified psychotic disorder: A population-based study.

A significant minority of unspecified psychosis presentations progress to schizophrenia. Clinical risk factors can inform targeted referral to specialized treatment programs, but few population studies have examined this. In this study, we used health administrative data for a population-based cohort from Manitoba, Canada to characterize the risk and identify vulnerable subgroups for a future diagnosis of schizophrenia after a diagnosis of unspecified psychotic disorder.
