Predicting offenses among individuals with psychiatric disorders - A machine learning approach

BackgroundActuarial risk estimates are considered the gold-standard way to assess whether psychiatric patients are likely to commit prospective criminal offenses. However, these risk estimates cannot individually predict the type of criminal offense a patient will subsequently commit, and often simply assess the general likelihood of crime occurring in a group sample. In order to advance the predictive utility of risk assessments, better statistical strategies are required. AimTo develop a machine learning model to predict the type of criminal offense committed in a large transdiagnostic sample of psychiatry patients, at an individual level. MethodMachine learning algorithms (Random Forest, Elastic Net, SVM), were applied to a representative and diverse sample of 1240 patients in the forensic mental health system. Clinical, historical, and sociodemographic variables were considered as potential predictors and assessed in a data-driven way. Separate models were created for each type of criminal offense, and feature selection methods were used to improve the interpretability and generalizability of our findings. ResultsSexual offenses can be predicted from nonviolent and violent offenses at an individual level with a sensitivity of 82.44% and specificity of 60.00%, using only 36 variables. Furthermore, in a binary classification model, sexual and violent offenses can be predicted at an individual level with 83.26% sensitivity and 77.42% specificity using only 20 clinical variables. Likewise, non-violent and sexual offenses can be individually predicted with 74.60% sensitivity and 80.65% specificity using 30 clinical variables. ConclusionThe current results suggest that machine learning models can show greater accuracy than gold-standard risk assessment tools (AUCs 0.70-0.80). However, unlike existing risk tools, this approach allows for the prediction of cases at an individual level, which is more clinically useful. Despite this, it is important to note that a large subset of patients in the sample were involved in the criminal system in the past, prior to an official diagnosis. Therefore, many of the variables that predict offenses may be derived from the issues of prior offenses. Irrespective of this, the accuracy of prospective models is expected to only improve with further refinement.

Experiences of recovery for Canadian forensic mental health patients and staff participating in a horse stables program

ABSTRACT Individuals in the forensic mental health system experience barriers to recovery and lack opportunities for engagement in meaningful activities. Equine interventions have the potential to promote recovery in forensic patients through opportunities to learn new skills and develop social relationships. However, the research on equine-assisted therapies in forensic mental health settings is limited and little is known about its role in recovery. The aim of this qualitative study is to explore forensic mental health patient and staff experiences of the Horse Stables Program at a psychiatric facility, and to identify aspects of the program deemed influential in facilitating patient recovery. Thirteen participants, forensic service users (n = 7) and staff (n = 6), involved in the program participated in semi-structured interviews. Interviews were transcribed and data were analyzed using Braun and Clarke’s six phases of thematic analysis. Findings revealed four themes related to recovery: 1) Radical Shift in Environment, 2) Opportunity for New Roles, 3) Building Meaningful Connections, and 4) Expanding Horizons. Final themes from this study were found to align with the literature on recovery in both general and forensic mental health settings. Participants expressed positive experiences at the stables and conveyed that the Horse Stables Program promoted recovery and well-being.

A Comparison of English and Dutch Long-Stay Patients in Forensic Psychiatric Care.

Background: A significant proportion of forensic patients in England are long-stayers. This can be problematic as individuals are kept in restrictive environments at potentially inappropriate levels of security for many years, sometimes decades. Improvements to the current English forensic mental health system to meet the needs of long-stay forensic patients more effectively might be informed by the Dutch service for long-stay forensic patients.Aims: To compare the characteristics of representative samples of long-stay patients in England and in the Netherlands in an attempt to draw conclusions on the degree to which the Dutch service model might be relevant to England.Method: This cross-sectional study explores the relevance of the Dutch service model by comparing the characteristics of representative samples of long-stay patients in England (n = 401) and the Netherlands (n = 102). Descriptive statistics and analyses of differences between groups are presented. The Risk-Need-Responsivity model was used to guide the selection of the study variables and structure the interpretation of the findings.Results: Compared to their English counterparts, the long-stay Dutch patients were less likely to be diagnosed with schizophrenia, but more likely to have personality disorder and have committed sex offences. The English group were younger at first conviction and at first custodial sentence. The total number of offences and the proportion of violent offenders were similar, but the Dutch HCR-20 scores indicated a significantly higher risk of violence.Conclusions: Whilst there may be barriers to adopting the Dutch service model in England, the differences in the characteristics of the two groups studied here do not necessarily preclude this approach.

French forensic mental health system during the COVID-19 pandemic

Many facilities involved in caring people diagnosed with mental health disorders who committed crime had to adapt to COVID-19 pandemic in France. Particularly, the impact of the COVID-19 pandemic on incarcerated people was the subject of many concerns. The COVID-19 pandemic also posed major challenges in secure psychiatric hospitals and for psychiatrist experts. Rapid changes in working practices occurred. Finally, the lockdown period was associated with an increase in domestic violence, especially gender-based violence and child abuse and neglect. Overall, the COVID-19 pandemic emphasized the well-known limitations of the French mental health system to manage people diagnosed with mental health disorders who committed crime and the urgent need for better recognition of forensic psychiatry in France.

Mental illness and the Lebanese criminal justice system: Practices and challenges

Forensic mental health services are a necessity for individuals involved in the criminal justice system. Such services involve two generally independent functions: assessment and treatment. A jurisdiction's legal system is a determinant of how such services are provided and to whom. In our study, we identified the Lebanese laws that address the rights and protections given to a mentally disordered defendant in the criminal justice system. We then analyzed how the Lebanese judicial system interprets and applies the written law in cases where the mental health of the defendant was brought up as an issue. We found that Lebanon's insanity test has a cognitive and a volitional component. However, there does not seem to be a uniform process regulating the use of the insanity defense: statutes do not address the procedural details and the cases we reviewed used various processes to reach their decisions. Based on our findings, we explored avenues for potential improvement in the Lebanese forensic mental health system.

Perceptions of procedural justice and coercion among forensic psychiatric patients: a study protocol for a prospective, mixed-methods investigation

BackgroundThe risk and recovery paradigms are the dominant frameworks informing forensic mental health services and have been the focus of increasing research interest. Despite this, there are significant gaps in our understanding of the nature of mental health recovery in forensic settings (i.e., ‘secure recovery’), and specifically, the key elements of recovery as perceived by forensic patients and their treatment providers. Importantly, we know little about how patients perceive the forensic mental health system, to what extent they see it as fair and legitimate, and how these perceptions impact upon treatment engagement, risk for adversity, and progress in recovery.MethodsIn this prospective, mixed-methods study, we investigate patient perceptions of procedural justice and coercion within the context of the forensic mental health system in Ontario, Canada (final N = 120 forensic patients and their primary care providers). We elicit patient self-assessments of risk and progress in recovery, and assess the degree of concordance with clinician-rated estimates of these constructs. Both qualitative and quantitative methods are used to assess the degree to which patient perceptions of coercion, fairness and legitimacy impact upon their level of treatment engagement, risk for adversity and progress in recovery. A prospective, two-year follow-up will investigate the impact of patient and clinician perspectives on outcomes in the domains of forensic hospital readmission, criminal reoffending, and rate of progress through the forensic system.DiscussionResults from this mixed-methods study will yield a rich and detailed account of patient perceptions of the forensic mental health system, and specifically whether perceptions of procedural fairness, justice and legitimacy, as well as perceived coercion, systematically influence patients’ risk for adversity, their ability to progress in their recovery, and ultimately, advance through the forensic system towards successful community living. Findings will provide conceptual clarity to the key elements of secure recovery, and illuminate areas of similarity and divergence with respect to how patients and clinicians assess risk and recovery needs. In doing so, knowledge from this study will provide a deep understanding of factors that promote patient safety and recovery, and provide a foundation for optimizing the forensic mental health system to improve patient outcomes.

Decriminalizing severe mental illness by reducing risk of contact with the criminal justice system, including for forensic patients.

Risk of contact with the criminal justice system (CJS) is greater among those with mental illness, including severe mental illness-an observation that many argue reflects a process of "criminalizing" mental illness. Forensic patients represent a subgroup at one end of a spectrum of such criminalization, typically with histories of serious violence and psychotic illness. Strategies for decriminalizing mental illness in this context should consider a range of approaches, including intervening to prevent CJS contact in those with severe mental illness, particularly in the early or emerging stages of psychosis. However, it may be that even gold standard mental healthcare applied universally is insufficient to address CJS contact risks. While there is now an extensive literature documenting the relatively low rates of repeat CJS contact for forensic patients released from secure care, appropriate comparison groups are lacking and the key ingredients of any benefits of treatment are unknown. The CJS may well have something to learn from forensic mental health systems and services given the abject failure to stem rates of prison-release reoffending internationally. Understanding how to best identify risk and effectively intervene to prevent CJS contact in those with mental illness, whether early in the course of psychosis or following release from secure care, remains a priority for those seeking to address the criminalization of mentally illness in our communities.

Perceptions of Restrictiveness in Forensic Mental Health: Do Demographic, Clinical, and Legal Characteristics Matter?

Where safe, forensic mental health systems should provide care in the least restrictive environment possible. Doing so can maximize patient autonomy and empowerment while minimizing unnecessary social disconnection and stigmatization. This study investigated whether patients' perceptions of restrictiveness were associated with demographic, clinical, and legal characteristics. The Forensic Restrictiveness Questionnaire (FRQ) was used to measure perceptions of restrictiveness in 235 patients in low-, medium-, and high-secure settings in England. The results showed that restrictiveness scores were significantly higher for patients who experienced an adverse event in the past week or were diagnosed with a personality disorder compared to those with a mental illness. A regression analysis suggested that only diagnosis was predictive of FRQ scores when controlling for perceptions of ward atmosphere and quality of life. Age, length of stay, ethnicity, level of security, legal section, and offence type were not associated with FRQ scores. Future research should investigate the roles that individual symptoms, insight into illness, mood, personality, and expectations of care have in influencing perceptions of restrictiveness.

Service Provider Perspectives on Female Forensic Mental Health Services in Zimbabwe: An Interpretative Phenomenological Analysis.

Service providers' perspectives on female forensic mental health services have not been explored in Zimbabwe. This study examined how health service providers in forensic mental health in Zimbabwe understand and interpret rehabilitation of female forensic psychiatric patients. An interpretive phenomenological study was completed. Service provider participants were selected via purposive sampling from two main Special Institutions. Data were collected using audio-recorded semistructured interviews and subjected to interpretive phenomenological analysis. Two master themes evolved from interview data: (a) conflicting legal documents of care and management of female forensic psychiatric patients; and (b) the forensic mental health system's processes, procedures, and resources impacting female forensic psychiatric rehabilitation. Findings of the study call for the need to balance between public safety interests and fulfilling clinical rehabilitation objectives.

Competence to stand trial and criminalization: an overview of the research.

Beginning in the 1960s, a steady decline in the number of inpatient psychiatric beds has occurred across the United States, primarily as a result of stricter civil commitment criteria and a societal movement toward deinstitutionalization. Concomitant with this decrease in psychiatric beds has been a steady increase in the number of mentally ill individuals who are arrested and processed through the criminal justice system as defendants. One consequence of this has been an explosion in the number of defendants referred for evaluations of their present mental state-adjudicative competence-and subsequently found incompetent and ordered to complete a period of competency restoration. This has resulted in forensic mental health systems that are overwhelmed by the demand for services and that are unable to meet the needs of these defendants in a timely manner. In many states, lawsuits have been brought by defendants who have had their liberties restricted as a result of lengthy confinements in jail awaiting forensic services. The stress on state-wide forensic systems has become so widespread that this has reached the level of a near-national crisis. Many states and national organizations are currently attempting to study these issues and develop creative strategies for relieving this overburdening of forensic mental health systems nationwide. The purpose of this article is to review the current state of the research on competence to stand trial and to highlight those issues that might be relevant to the issue of criminalization of individuals with mental illness in the United States.

Transitional housing in forensic mental health: considering consumer lived experience

BackgroundFor individuals involved in the forensic mental health system, access to transitional housing can offer a bridge between custody and independence. Using a methodology consistent with interpretative phenomenological analysis (IPA), this study considers the meaning associated with such participation. In this Canadian study, data was collected via interview with six individuals (n = 6) who resided, for a minimum six (6) months, in justice focused transitional housing that involved a partnership between a rural forensic mental health care facility and a nearby urban transitional housing provider.ResultsFollowing each participant interview, data was transcribed verbatim and coded for themes. Multiple methods were employed to support trustworthiness. Results indicate that participation enabled enhanced social participation, self-esteem/efficacy, community integration and renewal of daily living skills. Participants identified that involvement in justice focused transitional housing enabled development of community living skills, cultivated self-confidence and enhanced personal resilience in their transition from a secure forensic mental health facility to more independent community tenure.ConclusionsParticipants in this research clearly identified the importance of transitional housing programs in supporting their move from a forensic mental health facility to the community. Not all forensic involved individuals will need this type or level of support to support their transition. Practically, however, the nature of forensic hospitalization can present real challenges for occupational participation and maintenance of community living skills. Transitional housing, accountable to unique forensic mental health and justice inputs, can offer a valuable bridge to the community.

Short-term outcomes for forensic patients receiving an absolute discharge under the Canadian Criminal Code

There is insufficient knowledge regarding outcomes among persons who are no longer supervised by the forensic mental health system, and consequently little data to inform public perception regarding the risk of harm posed by such persons. We performed a retrospective case audit and one-year follow-up of all patients receiving an absolute discharge from compulsory forensic care in the years 2013 and 2014 (N = 60) and report on the prevalence of outcomes concerning mental health deterioration, treatment non-compliance, hospital readmission, substance use and recidivism. In the year following absolute discharge, rates of medication non-compliance, hospital readmission and violence increased significantly (odds ratios = 3.51–10.41). Discharged patients who engaged in violence or reoffending (n = 10) were characterized by greater substance use problems, and were less likely to be rated as low risk on the HCR-20. A comparison to a matched sample of community-dwelling but not absolutely discharged patients revealed that those not yet discharged experienced more symptoms of mental illness and greater problems with treatment compliance and social support. The low base rate of serious violence among absolutely discharged patients suggests that the decision-making model employed by the review board in our jurisdiction is a reasonably accurate and balanced one.

A prospective study of pathways to hospital readmission in Canadian forensic psychiatric patients

Individuals admitted to secure care often experience lengthy hospitalizations and are likely to be admitted on more than one occasion. In the context of growing demand and costs associated with secure care, the current study investigates the frequency and reasons for readmission among 87 forensic patients recently discharged into the community. We identify risk factors that are associated with the likelihood of readmission and describe areas of overlap and discordance with the existing literature in civil and forensic samples. Using a prospective design that included patient follow-up interviews and records review, we found that 28% of patients were readmitted on one or more occasions over a 12-month period. Psychiatric decompensation, substance use, and treatment non-adherence were the central reasons prompting readmission. Patients with one or more readmissions were found to have spent significantly more time in the forensic mental health system as compared to patients not readmitted. They were more likely to have a substance use disorder and were estimated to be at higher risk for violence. Results replicate the finding of low rates of serious violence and reoffending among discharged forensic patients, and substantiate the centrality of substance use as a growing and clinically important treatment issue.

Differences between British and Japanese perspectives on forensic mental health systems: A preliminary study.

AIMTo clarify the differences in views on forensic mental health (FMH) systems between the United Kingdom and Japan.METHODSWe conducted a series of semi-structured interviews with six leading forensic psychiatrists. Based on a discussion by the research team, we created an interview form. After we finished conducting all the interviews, we qualitatively analyzed their content.RESULTSIn the United Kingdom the core domain of FMH was risk assessment and management; however, in Japan, the core domain of FMH was psychiatric testimony. In the United Kingdom, forensic psychiatrists were responsible for ensuring public safety, and psychopathy was identified as a disease but deemed as not suitable for medical treatment. On the other hand, in Japan, psychopathy was not considered a mental illness.CONCLUSIONIn conclusion, there are considerable differences between the United Kingdom and Japan with regard to the concepts of FMH. Some ideas taken from both cultures for better FMH practice were suggested.

What Does Success Look Like in the Forensic Mental Health System? Perspectives of Service Users and Service Providers.

Outcomes research in forensic mental health (FMH) has concentrated on reoffending as the principal indicator of success. Defining success in one-dimensional, negative terms can create a distorted view of the diverse objectives of the FMH system. This qualitative study examined the complexity of success from the perspectives of people in the FMH system. Interviews were conducted with 18 forensic service users and 10 forensic service providers. Data were analyzed inductively using thematic analysis to identify predominant themes. The participants conceptualized success as a dynamic process materializing across six different domains in the context of the FMH system: (a) normal life, (b) independent life, (c) compliant life, (d) healthy life, (e) meaningful life, and (f) progressing life. The results indicate that people who provide or use FMH services emphasize a broad range of processes and outcomes, apart from public safety, when they think about success.

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.

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.

Forensic focused treatment planning: a new standard for forensic mental health systems.

Almost no literature addresses treatment planning for the forensic psychiatric patient. In the absence of such guidance, recovery-oriented multifocal treatment planning has been imported into forensic mental health systems from community psychiatric settings, despite the fact that conditions of admission and discharge are vastly different for forensic psychiatry inpatients. We propose that instead of focusing on recovery, forensic treatment planning should prioritize forensic outcomes, such as restoration of trial competence or mitigation of violence risk, as the first steps in a continuum of care that eventually leads to the patient's ability to resolve forensic issues and return to the community for recovery-oriented care. Here we offer a model for treatment planning in the forensic setting.

Defining outcome measures of hospitalization for assessment in the Japanese forensic mental health scheme: a Delphi study.

BackgroundA new legislation concerning forensic mental health was established by the Japanese Government in 2005, the “Act on Medical Care and Treatment for the Persons Who Had Caused Serious Cases under the Condition of Insanity,” or the Medical Treatment and Supervision (MTS) Act. Since it was passed, however, there has been broad controversy over Hospitalization for Assessment (HfA), the first stage of the MTS scheme.MethodsFollowing a comprehensive literature search to assemble a list of candidates, we conducted a Delphi study to establish standard outcome measures for HfA.ResultsFive Delphi rounds were conducted by 19 panelists including medical practitioners and lawyers. A total of 139 items were accepted as outcome measures for HfA based on panel agreement.ConclusionThe Delphi study established a list of HfA outcome measures for the MTS act, which will contribute to the optimization of the new forensic mental health system in Japan.Electronic supplementary materialThe online version of this article (doi:10.1186/1752-4458-9-7) contains supplementary material, which is available to authorized users.

Forensic mental health professionals’ perceptions of psychopathy: A prototypicality analysis of the Comprehensive Assessment of Psychopathic Personality in Sweden.

Assessments of psychopathic traits are used on a routine basis in forensic evaluations across Westernized countries. Despite this, consensus has not yet emerged concerning what exactly are the "core" features of this construct. Moreover, relatively little is known about how practitioners in the field construe this disorder. This study explored perceptions and attitudes regarding psychopathy among individuals working in the forensic mental health system (N = 90) in Sweden. Participants provided prototype ratings of what they considered to be core psychopathy features based on the Comprehensive Assessment of Psychopathic Personality (CAPP), a model that increasingly is the focus of research in North America and Europe. The study protocol also included questions regarding (a) global perceptions and attitudes about a number of aspects of the psychopathy construct (e.g., personal experience, perceived prevalence), and (b) attitudinal scales that assessed perceived correlates of psychopathic traits across a variety of domains (e.g., violence proneness, treatment amenability) and moral judgments and attitudes concerning how psychopathic offenders should be treated within the legal system. The majority of the 33 individual CAPP items and the six CAPP scales were rated as at least moderately prototypical of psychopathy, with Dominance, Self, and Attachment domains obtaining the highest mean ratings. Participants viewed psychopaths as more likely to commit crimes than the average criminal, without being blatantly "evil" people. We believe our results help to advance our understanding of the psychopathy construct by exploring forensic professionals' perceptions of this disorder in general and in relation to the CAPP model specifically.
