Staff supported community outings among forensic mental health patients: patient characteristics, rehabilitative goals, and (the absence of) adverse outcomes.

Mental health professionals are tasked with making difficult clinical decisions in treatment settings. In the forensic system, decision making regarding staff supervised community outings (SSCOs) provides a significant challenge due to the need to balance patient liberties, mental health recovery, and public safety. This study explored the characteristics and rehabilitative nature of SSCOs, characteristics of patients attending SSCOs, and any adverse events that occurred during the outings. Employing a cross-sectional design, 110 patients who participated in SSCOs over a one-year period from a Canadian Forensic Psychiatric Hospital were included. Clinical records were reviewed to capture patient and SSCO variables. Descriptive analyses were used to calculate participant, risk, SSCO, and adverse event characteristics. Qualitative analysis was used to explore the purpose of SSCOs and rehabilitative progress that occurred during the outings. Patients attending SSCOs were comprised of long-stay patients with over half having committed a violent index offence. Almost 75% of patients had a moderate/high risk for violence and 50% of the patients had a moderate/high risk of absconding. During the study period, 463 SSCOs were completed. Most outings focused on developing skills for daily living and staff comments suggested many patients developed skills in these areas. Despite considerable risk profiles and public concern regarding forensic patients having community access, there was a single occurrence of unauthorized leave and no instances of violence or substance use. This research can disrupt stigma, demonstrating that SSCOs support a specific rehabilitative intent, promote community reintegration, and maintain public safety.

Barriers and facilitators of access and utilization of mental health services among forensic service users along the care pathway.

BACKGROUND: The verdict of Not Criminally Responsible on account of a Mental Disorder (NCRMD) is increasingly used to access specialized mental health services in Canada and elsewhere. This situation highlights the importance of ensuring timely access to services in the community to prevent violence and justice involvement. The objective of the present study is to identify individual and contextual barriers and facilitators of access to mental health services during the period preceding an offense leading to a verdict of NCRMD. METHODS: The sample includes 753 people found NCRMD in Québec, Canada. All episodes of mental health hospitalizations and service use before the index offense were identified using provincial administrative health data, for an average period of 4.5 years. Access was conceptualized as a function of the possibility of seeking, reaching and receiving appropriate health care services, based on Lévesque and colleagues patient-centred model of access to care. Generalized linear models were computed to identify the individual and contextual predictors of: (1) seeking mental healthcare (at least one contact with any type of services for mental health reasons); (2) reaching psychiatric care (at least one contact with a psychiatrist); (3) receiving psychiatric care, operationalized as (3a) continuity and (3b) intensity. Factors associated with volume of emergency mental health services were examined as exploratory analysis. RESULTS: Geographical considerations were highly important in determining who reached, and who received specialized mental health care - above and beyond individual factors related to need. Those who lived outside of major urban centres were 2.6 times as likely to reach psychiatric services as those who lived in major urban centres, and made greater use of emergency mental health services by 2.1 times. Living with family decreased the odds of seeking mental healthcare by half and the intensity of psychiatric care received, even when adjusting for level of need. CONCLUSIONS: Findings support efforts to engage with the family of service users and highlights the importance of providing resources to make family-centred services sustainable for health practitioners. Health policies should also focus on the implementation of outreach programs, such as Forensic Assertive Community Treatment teams as part of prevention initiatives.

Emergency department use for mental and substance use disorders: descriptive analysis of population-based, linked administrative data in British Columbia, Canada.

OBJECTIVES: Information on emergency department (ED) visits for mental and substance use disorders (MSUDs) is important for planning services but has not been explored in British Columbia (BC), Canada. We describe all MSUD ED visits for people ages 15 and older in the province of BC in 2017/2018 and document trends in MSUD ED visits between 2007/2008 and 2017/2018 by disorder group. DESIGN: Population-based linked administrative data comprised of ED records and physician billings capturing all MSUD ED visits in BC. SETTING: BC is Canada's westernmost province with a population of approximately 5 million. Permanent residents receive first-dollar coverage for all medically necessary services provided by licensed physicians or in hospitals, including ED services. POPULATION: All people age >15 with MSUD ED visits during the study period. MEASURES: All claims with a service location in the ED or corresponding to fee items billed only in the ED were examined alongside ED visits reported through a national reporting system. Patient characteristics (sex/gender, age, location of residence, income, treated disorders and comorbidities) and previous outpatient service use for all ED visits by visit diagnosis are also described. RESULTS: A total of 72 363 people made 134 063 visits to the ED in 2017/2018 for needs related to MSUD. MSUD ED visits have increased since 2010, particularly visits for substance use and anxiety disorders. People with more frequent visits were more likely to be male, on public prescription drug plans for income assistance, prescribed psychiatric medications, and living in lower-income neighbourhoods. They used more community-based primary care and psychiatry services and had lower continuity of primary care. CONCLUSIONS: MSUD ED visits are substantial and growing in BC. Findings underscore a need to strengthen and target community healthcare services and adequately resource and support EDs to manage growing patient populations.

Not a "Get Out of Jail Free Card": Comparing the Legal Supervision of Persons Found Not Criminally Responsible on Account of Mental Disorder and Convicted Offenders.

BACKGROUND: The public often perceives the insanity defense as a "get out of jail free card". Conversely, several studies demonstrate the substantial control imposed upon these defendants. This study compares Review Boards decisions regarding people found not criminally responsible on account of mental disorder (NCRMD) to criminal courts decisions regarding convicted offenders for similar offenses in Canada. METHOD: Detention, using logistic regression, and duration under detention and supervision, using Cox regression, were compared between a cohort of 1794 individuals found NCRMD in three Canadian provinces (Quebec, Ontario, and British Columbia) between 2000 and 2005 followed until 2008 from the National Trajectory Project and a national sample of 3,20,919 Canadians convicted of criminal offense from Statistics Canada's Criminal Court Survey. RESULTS: Individuals found NCRMD are 3.8 times (95% CI 3.4-4.3) more likely to be detained than convicted offenders as well as 4.8 times (95% CI 4.5-5.3) and 2.9 times (95% CI 2.6-3.1) less likely to be released from detention and supervision, respectively. One year after the verdict, 73% of the NCRMD accused were still under legal supervision and 42% were still in detention, whereas these proportions were, respectively, 41 and 1% for their convicted counterparts. Interaction effects show that sex, age, jurisdiction, number of offenses, and severity of crimes committed have a differential impact on decisions applied to NCRMD accused compared to convicted persons. CONCLUSION: Contrary to popular perceptions, the insanity defense is not a loophole. Differences as to factors influencing the trajectories of the two samples confirm that Review Boards are able to distance their practices from the criminal courts and can set aside, at least in part, the principles of proportionality and punitiveness governing the traditional sentencing practices.

Risk of overdose-related death for people with a history of incarceration.

BACKGROUND AND AIMS: Reported associations between previous incarceration and the risk of overdose-related death are substantially heterogeneous, and previous studies are limited by an inability to control for confounding factors in risk assessment. This study investigated the associations of overdose-related death with previous incarceration and the number or cumulative duration of previous incarcerations, and individual or neighborhood characteristics that may potentially modify the associations. DESIGN AND SETTING: A cohort study using a 20% random sample of residents in British Columbia, Canada. PARTICIPANTS: A total of 765 690 people aged 23 years or older at baseline as of 1 January 2015. Mean age was 50 years; 49% were males. MEASUREMENTS: Previous incarcerations that occurred during the 5-year exposure period (January 2010 to December 2014) were identified using provincial incarceration records. Overdose-related deaths that occurred during the 3-year follow-up period (January 2015 to December 2017) were identified using linked administrative health data. Baseline individual and neighborhood characteristics were retrieved from the provincial health insurance data. FINDINGS: In the cohort, 5743 people had an incarceration history during the exposure period, and 634 people died from drug overdose during the follow-up period. The mortality rate was 897 and 22 per 100 000 person-years for people who did and did not have an incarceration history, respectively. After adjusting for baseline individual and neighborhood characteristics (without any interaction term), people who had an incarceration history were 4.04 times (95% confidence interval 3.23-5.06) more likely to die from drug overdose compared with people without an incarceration history. The association was stronger for females, people without diagnoses of substance use disorder and people without dispensation of opioids for pain or benzodiazepines (P < 0.001 for each interaction term). There was no discernible linear trend between the number or cumulative duration of previous incarcerations and the risk of overdose-related death. CONCLUSIONS: Previous incarceration appears to be a major risk factor for overdose-related death.

Examining the Relationships between Cumulative Childhood Adversity and the Risk of Criminal Justice Involvement and Victimization among Homeless Adults with Mental Illnesses after Receiving Housing First Intervention.

OBJECTIVES: Exposure to adverse childhood experiences (ACEs) is associated with increased risk of criminal justice involvement and repeated victimization among homeless individuals. This study aimed to (1) examine whether the relationship between cumulative ACE score and odds of experiencing criminal justice involvement and victimization remains significant over time after receiving the Housing First (HF) intervention and (2) investigate the moderating effect of cumulative ACE score on the effectiveness of the HF intervention on the likelihood of experiencing these outcomes among homeless individuals with mental illnesses. METHODS: We used longitudinal data over the 2-year follow-up period from the At Home/Chez Soi demonstration project that provided HF versus treatment as usual (TAU) to homeless adults with mental illness in five Canadian cities (N = 1,888). RESULTS: In all 4 follow-up time points, the relationship between cumulative ACE score and both outcomes remained significant, regardless of study arm (HF vs. TAU) and other confounding factors. However, cumulative ACE score did not moderate intervention effects on odds of experiencing either outcome, suggesting that the effectiveness of HF versus TAU, with regard to the odds of being victimized or criminal justice involvement, did not differ by cumulative ACE scores over the course of study. CONCLUSIONS: Findings suggest that providing services for homeless individuals with mental illness should be trauma informed and include specialized treatment strategies targeting the experience of ACEs and trauma to improve their treatment outcomes. An intensive approach is required to directly address the problem of criminal justice involvement and victimization in these individuals.

Childhood Maltreatment and the Risk for Criminal Justice Involvement and Victimization Among Homeless Individuals: A Systematic Review.

Homeless individuals are at higher risk of criminal justice involvement (CJI) and victimization compared to their housed counterparts. Exposure to childhood maltreatment (CM; e.g., abuse, neglect) is one of the most significant predictors of CJI and victimization among homeless populations. The aim of this systematic review was to synthesize current knowledge regarding the relationship between CM and CJI and victimization among homeless individuals. Guided by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) methods, a systematic search was performed using PsycINFO, MEDLINE, Embase, Web of Science, and the Cumulative Index to Nursing and Allied Health Literature for published studies investigating the relationship between CM and CJI and victimization among homeless samples. We identified 20 studies that met the inclusion criteria. Findings showed that across the majority of studies, CM, and in particular childhood physical (CPA) and sexual (CSA) abuse, is associated with increased risk of both CJI and victimization, regardless of various important factors (e.g., sociodemographic characteristics, psychiatric disorders, substance use). These findings support the need for prevention and treatment for "families at risk" (i.e., for intimate partner violence, child abuse and neglect) and also document the need for trauma-informed approaches within services for homeless individuals. Future research should focus on prospective designs that examine victimization and CJI in the same samples.

Changing characteristics of forensic psychiatric patients in Ontario: a population-based study from 1987 to 2012.

PURPOSE: To quantify the demand for forensic psychiatric services in Ontario over the past 25 years and investigate whether the sociodemographic, clinical and offense-based characteristics of forensic patients have changed over time. METHODS: We investigated all forensic admissions from 1987 to 2012 resulting in a disposition of Not Criminally Responsible on account of Mental Disorder (N = 2533). We present annual proportions of patients with specified sociodemographic, clinical and offense characteristics, and investigate whether the duration of forensic system tenure varies as a function of admission year, psychiatric diagnosis, or index offense. RESULTS: There has been a steady increase in forensic admissions over this time period, particularly individuals with comorbid substance use disorders and individuals of non-Caucasian ethno-racial background. The proportion of persons committing severe violence has remained low and has decreased over time. Having a comorbid personality, neurological, or substance use disorder significantly increased forensic system tenure, as did committing a violent offense. Individuals who came into the system in earlier years had slower rates of discharge compared to more recent admissions. CONCLUSIONS: Defining the trends characterizing the growth of the forensic population has important policy implications, as forensic services are costly and involve a significant loss of liberty. The current results indicate that young, substance abusing individuals of diverse ethno-racial backgrounds and who commit relatively low-level violence comprise an increasing proportion of Ontario's forensic population, and suggest that treatment must be optimized to best serve the needs of these individuals.

Supervision trajectories of male juvenile offenders: growth mixture modeling on SAVRY risk assessments.

BACKGROUND: Structured risk/need assessment tools are increasingly used to orientate risk reduction strategies with juvenile offenders. The assumption is that the risk/need items on these tools are sufficiently sensitive to measure changes in the individual, family and/or contextual characteristics of juvenile offenders. However, there is very little research demonstrating the capacity of these tools to measure changes in juvenile offenders. Congruent with the developmental and life-course criminology theories (DLC) the objective of this study is to explore the existence of heterogeneous trajectories of juvenile offenders across the juvenile justice system as measured through five empirical risk/need areas based on the Structured Assessment of Violence Risk in Youth (SAVRY), one of the most widely applied risk assessment tools for juveniles. METHODS: This longitudinal study included 5205 male juvenile offenders who transitioned through the Catalan juvenile justice system between 2006 and 2014. During intervention they received at least two, and a maximum of seven, consecutive SAVRY risk/need assessments over an 18-month period. The heterogeneity of latent class trajectories was explored through growth mixture modeling (GMM). The trajectory class membership was linked to covariates through multinomial logistic regression analyses. RESULTS: Through GMM three to four heterogeneous trajectories, with high quality of separation, were identified in each of the risk/need areas. The trajectories with low risk/needs (45-77% of the sample) remained low and presented a very limited increase in risk/needs during the 18-month period. The high risk/need trajectories (20-37% of the sample) showed a limited decrease or no change. Between 5 and 13% of the sample had large reductions in their risk/needs levels, and approximately 5% showed a large increase in risk/needs. CONCLUSIONS: In line with the DLC theories this study shows that trajectories on criminogenic risk/needs can be heterogeneous and indicate distinct rates of change over time. The results of this study also may suggest a limited sensibility to measure change over time of SAVRY's risk and protective items. Suggestions to improve the sensitivity of measuring change over time, such as shorter time frames or future-oriented time frames for the scoring of the items, are offered.

Expanding the early and late starter model of criminal justice involvement for forensic mental health clients.

The early and late starter model provides one of the most enduring frameworks for understanding the developmental course and severity of violence and criminality among individuals with severe mental illness. We expanded the model to account for differences in the age of onset of criminal behavior and added a group with no prior contact with the justice or mental health systems. We sampled 1,800 men and women found Not Criminally Responsible on account of Mental Disorder in 3 Canadian provinces. Using a retrospective file-based study, we explored differences in criminal, health, demographic, and social functioning characteristics, processing through the forensic psychiatric system and recidivism outcomes of 5 groups. We replicated prior research, finding more typical criminogenic needs among those with early onset crime. Those with crime onset after mental illness were more likely to show fewer criminogenic needs and to have better outcomes upon release than those who had crime onset during adulthood, before mental illness. Individuals with no prior contact with mental health or criminal justice had higher functioning prior to their crime and had a lower risk of reoffending. Given little information is needed to identify the groups, computing the distribution of these groups within forensic mental health services or across services can provide estimates of potential intensity or duration of services that might be needed. This study suggests that distinguishing subgroups of forensic clients based on the sequence of onset of mental illness and criminal behavior and on the age of onset of criminal behavior may be useful to identify criminogenic needs and predict outcomes upon release. This updated framework can be useful for planning organization of services, understanding case mix, as well as patient flow in forensic services and flow of mentally disordered offenders in correctional services.

Adverse Childhood Experiences and the Risk of Criminal Justice Involvement and Victimization Among Homeless Adults With Mental Illness.

OBJECTIVE: Exposure to adverse childhood experiences (ACEs) is highly prevalent among homeless individuals and is associated with negative consequences during homelessness. This study examined the effect of ACEs on the risk of criminal justice involvement and victimization among homeless individuals with mental illness. METHODS: The study used baseline data from a demonstration project (At Home/Chez Soi) that provided Housing First and recovery-oriented services to homeless adults with mental illness. The sample was recruited from five Canadian cities and included participants who provided valid responses on an ACEs questionnaire (N=1,888). RESULTS: Fifty percent reported more than four types of ACE, 19% reported three or four types, 19% reported one or two, and 12% reported none. Rates of criminal justice involvement and victimization were significantly higher among those with a history of ACEs. For victimization, the association was significant for all ten types of ACE, and for justice involvement, it was significant for seven types. Logistic regression models indicated that the effect of cumulative childhood adversity on the two outcomes was significant regardless of sociodemographic factors, duration of homelessness, and psychiatric diagnosis, with one exception: the relationship between cumulative childhood adversity and criminal justice involvement did not remain significant when the analysis controlled for a diagnosis of posttraumatic stress disorder and substance dependence. CONCLUSIONS: Findings support the need for early interventions for at-risk youths and trauma-informed practice and violence prevention policies that specifically target homeless populations.

The Perceived Impact of Trauma-Focused Research on Forensic Psychiatric Patients With Lifetime Victimization Histories.

This study examined the perceived costs, benefits, and motivations for participating in individual trauma-focused interviews among forensic psychiatric patients ( N = 74). The majority of our participants were male, and 100% endorsed adverse childhood experiences (e.g., abuse, neglect) or exposure to potentially traumatic events (e.g., assault). Levels of posttraumatic avoidance (41.9%), reexperiencing (59.5%), and increased arousal (51.3%) were high. In line with previous studies, our findings suggest an overall positive research experience in this sample. In spite of extensive histories of lifetime victimization we did not find an association between victimization, posttraumatic symptomatology, and a negative research experience. Our findings suggest that participation in trauma-focused research is not only possible with, but also potentially beneficial for forensic patients.

Predictors of criminal justice system trajectories of homeless adults living with mental illness.

OBJECTIVES: This study examines whether baseline profiles of criminal justice involvement are independently associated with 24-month trajectories of arrests in a sample of homeless adults living with mental illness. METHODS: Interviews with justice-involved participants from the At Home/Chez soi project, a multisite trial of Housing First in Canada, yielded information related to arrests, as well as demographic, clinical, and contextual predictors of criminal justice system involvement. All potential predictors were entered into logistic and negative binomial regression models to assess their effect on re-arrest. RESULTS: Of the 584 individuals involved with the criminal justice system at baseline, and for whom follow-up data was obtained, 347 (59%) were re-arrested within two years. Of those, 283 (82%) had an episodic pattern of re-arrest and 64 (18%) had a continuous trajectory of re-arrest. Results indicate that participants involved with the legal system for minor (mostly theft and public order) offenses at baseline were most likely to be repeatedly arrested. Gender, Aboriginal status, and recent victimization were also independently associated with re-arrest. CONCLUSIONS: These findings have implications for the delivery of police and clinical services alike, as well as for policies that aim to divert vulnerable individuals who commit minor crimes from a long-term trajectory of justice involvement.

Housing Trajectories of Forensic Psychiatric Patients.

The objectives of this study were to describe the disposition and housing trajectories of individuals found Not Criminally Responsible on account of Mental Disorder (NCRMD), and the factors that predict different trajectories. To do so, disposition and housing status were coded for 934 NCRMD patients over a 36-month follow-up period. Sequential data analysis resulted in four distinct trajectories: detention in hospital, conditional discharge in supportive housing, conditional discharge in independent housing, and absolute discharge to unknown housing. The likelihood of a placement in supportive housing compared with detention significantly decreased for individuals with a higher index offense severity. Less restrictive trajectories were significantly predicted by clinical factors. The results revealed little change in the disposition and housing trajectories of NCRMD patients. Furthermore, decisions about disposition and housing placement reflect a knowledge-practice gap between risk factors known to be predictive of community resources use in the forensic population.

Factors Associated with Review Board Dispositions following Re-hospitalization among Discharged Persons found Not Criminally Responsible.

In the Canadian forensic mental health system, a person found Not Criminally Responsible on account of Mental Disorder (NCRMD) and given a conditional discharge returns to the community while remaining under the jurisdiction of a provincial/territorial Review Board. However, the individual can be re-hospitalized while on conditional discharge, for reasons such as substance use, violation of conditions, or violence. We investigated whether being re-hospitalized has an impact on the factors associated with the subsequent Review Board disposition. Persons found NCRMD from the three largest Canadian provinces who were conditionally discharged at least once during the observation period were included in the sample (N = 1,367). These individuals were involved in 2,920 disposition hearings; nearly one-third of patients (30%) were re-hospitalized after having been conditionally discharged by the Review Board. The factors examined included the scales of the Historical Clinical Risk Management-20 and salient behavior that occurred since the previous hearing, such as substance use or violence. The greater presence of clinical items resulted in a greater likelihood of a hospital detention decision at the next hearing. The effect was larger for the re-hospitalized group than for the group who successfully remained in the community since the last hearing. The results suggest that dynamic factors, specifically indicators of mental health, are heavily weighted by the Review Boards, consistent with the literature on imminent risk and in line with the NCRMD legislation.

Profiles of criminal justice system involvement of mentally ill homeless adults.

OBJECTIVES: This study aims to examine the rates of self-reported contacts with the criminal justice system among homeless adults with mental illness, to identify the characteristics of participants who have had contacts with the criminal justice system, to report the dimensional structure of criminal justice system involvement in this sample, and to identify typologies of justice-involved participants. METHODS: Self-report data on criminal justice system involvement of 2221 adults participating in a Canadian Housing First trial were analyzed using multiple correspondence and cluster analysis. RESULTS: Almost half of the participants had at least one contact with the criminal justice system in the 6months prior to study enrollment. Factors associated with justice involvement included age, gender, ethnic background, diagnosis, substance misuse, impulse control, compliance, victimization, service use, and duration of homelessness. A typology of criminal justice involvement was developed. Seven criminal justice system involvement profiles emerged; substance use and impulse control distinguished the clusters, whereas demographic and contextual variables did not. CONCLUSIONS: The large number of profiles indicates the need for a diverse and flexible range of interventions that could be integrated within or in addition to current support of housing services, including integrated substance use and mental health interventions, risk management strategies, and trauma-oriented services.

Identifying gender specific risk/need areas for male and female juvenile offenders: Factor analyses with the Structured Assessment of Violence Risk in Youth (SAVRY).

By constructing risk assessment tools in which the individual items are organized in the same way for male and female juvenile offenders it is assumed that these items and subscales have similar relevance across males and females. The identification of criminogenic needs that vary in relevance for 1 of the genders, could contribute to more meaningful risk assessments, especially for female juvenile offenders. In this study, exploratory factor analyses (EFA) on a construction sample of male (n = 3,130) and female (n = 466) juvenile offenders were used to aggregate the 30 items of the Structured Assessment of Violence Risk in Youth (SAVRY) into empirically based risk/need factors and explore differences between genders. The factor models were cross-validated through confirmatory factor analyses (CFA) on a validation sample of male (n = 2,076) and female (n = 357) juvenile offenders. In both the construction sample and the validation sample, 5 factors were identified: (a) Antisocial behavior; (b) Family functioning; (c) Personality traits; (d) Social support; and (e) Treatability. The male and female models were significantly different and the internal consistency of the factors was good, both in the construction sample and the validation sample. Clustering risk/need items for male and female juvenile offenders into meaningful factors may guide clinicians in the identification of gender-specific treatment interventions.

Research Priorities in Mental Health, Justice, and Safety: A Multidisciplinary Stakeholder Report.

This paper is based on the report following the National Research Agenda Meeting on Mental Health, Justice, and Safety held in Montreal on November 19, 2014, which convened academics; health, social, and legal professionals; and people with lived experience of mental illness from across Canada. The goal was to identify research priorities addressing relevant knowledge gaps and research strategies that can translate into public policy action and improvements in evidence-based services. Participants identified key challenges: (1) inadequate identification and response to needs by civil mental health services and frontline law enforcement, (2) limited specialized resources in forensic and correctional settings, (3) fragmented care and gaps between systems, (4) limited resources for adequate community reintegration, and (5) poor knowledge transfer strategies as obstacles to evidence-based policies. Knowledge gaps were identified in epidemiology and risk reduction, frontline training and programs, forensic and correctional practices, organizations and institutions, knowledge transfer, and rehabilitation. Finally, participants identified potential sources of support to conduct real time research with regard to data collection and sharing. The findings represent a roadmap for how forensic mental health systems can best proceed to address current challenges through research and practice initiatives, drawing from lived, clinical and research experiences of a multidisciplinary group of experts.

The national trajectory project of individuals found not criminally responsible on account of mental disorder in Canada. Part 1: context and methods.

The National Trajectory Project examined longitudinal data from a large sample of people found not criminally responsible on account of mental disorder (NCRMD) to assess the presence of provincial differences in the application of the law, to examine the characteristics of people with serious mental illness who come into conflict with the law and receive this verdict, and to investigate the trajectories of NCRMD-accused people as they traverse the mental health and criminal justice systems. Our paper describes the rationale for the National Trajectory Project and the methods used to collect data in Quebec, Ontario, and British Columbia, the 3 most populous provinces in Canada and the 3 provinces with the most people found NCRMD.
