Abstract

Background

International studies show that adults with intellectual and developmental disabilities (IDD) are disproportionately represented in the criminal justice and forensic mental health systems; however, it is difficult to capture their involvement across systems in any one jurisdiction.

Aims

The current study aimed to estimate the prevalence of IDD across different parts of the criminal justice and forensic mental health systems in Ontario and to describe the demographic and clinical profiles of these individuals relative to their counterparts without IDD.

Methods

This project utilised administrative data to identify and describe the demographic and clinical characteristics of adults with IDD and criminal justice or forensic involvement across four sectors: federal correctional facilities, provincial correctional facilities, forensic inpatient mental health care and community mental health programmes. Questions were driven by and results were contextualised by a project advisory group and people with lived experience from the different sectors studied, resulting in a series of recommendations.

Results

Adults with IDD were over-represented in each of the four settings, ranging from 2.1% in federal corrections to 16.7% in forensic inpatient care. Between 20% (forensic inpatient) and 38.4% (provincial corrections) were under the age of 25 and between 34.5% (forensic inpatient) and 41.8% (provincial corrections) resided in the lowest income neighbourhoods. Medical complexity and rates of co-occurring mental health conditions were higher for people with IDD than those without IDD in federal and provincial corrections.

Conclusions

Establishing a population-based understanding of people with IDD within these sectors is an essential first step towards understanding and addressing service and care needs. Building on the perspectives of people who work in and use these systems, this paper concludes with intervention recommendations before, during and after justice involvement.

安大略省刑事司法和法医心理健康系统中的智力和发育障碍问题：用数据说话。

背景：国际研究表明，有智力和发育障碍的成年人在刑事司法和法医精神卫生系统中的比例过高；然而，很难在任何一个司法管辖区的各个系统中掌握他们的参与情况。目的：本研究旨在估算安大略省刑事司法和法医精神卫生系统不同部门中智力和发育障碍的患病率，并描述这些人相对于没有智力和发育障碍的人的人口和临床特征：该项目利用管理数据来识别和描述患有 IDD 并涉及刑事司法或法医的成年人的人口统计学和临床特征，这些数据涉及四个部门：联邦教养机构、省级教养机构、法医住院精神健康护理和社区精神健康计划。项目咨询小组和来自所研究的不同部门、具有生活经验的人士对问题进行了深入探讨，并对结果进行了背景分析，最终提出了一系列建议：在这四种环境中，患有 IDD 的成人所占比例都很高，从联邦教养院的 2.1%到法医住院护理的 16.7%不等。20%（法医住院患者）和38.4%（省级教养所）的患者年龄在25岁以下，34.5%（法医住院患者）和41.8%（省级教养所）的患者居住在收入最低的社区。在联邦和省级教养机构中，IDD患者的医疗复杂性和并发精神疾病的比例高于非IDD患者：对这些部门中的 IDD 患者建立基于人群的了解，是了解和满足服务与护理需求的重要第一步。基于在这些系统中工作和使用这些系统的人的观点，本文最后提出了在司法介入之前、期间和之后的干预建议。

期刊介绍： Criminal Behaviour & Mental Health – CBMH – aims to publish original material on any aspect of the relationship between mental state and criminal behaviour. Thus, we are interested in mental mechanisms associated with offending, regardless of whether the individual concerned has a mental disorder or not. We are interested in factors that influence such relationships, and particularly welcome studies about pathways into and out of crime. These will include studies of normal and abnormal development, of mental disorder and how that may lead to offending for a subgroup of sufferers, together with information about factors which mediate such a relationship.
