Adverse childhood events and self-harming behaviours among individuals in Ontario forensic system: the mediating role of psychopathy.

BACKGROUND: Adverse childhood events (ACEs), psychopathy, and self-harming behaviours are prevalent among individuals in the forensic psychiatry system. While existing literature suggests that ACEs, self-harm, and psychopathy are interrelated, little is known about the interplay of psychopathic traits in this relationship. The present study aimed to determine the mediating role of psychopathy in the relationship between ACEs and self-harming behaviours in forensic patients. METHODS: This was a retrospective study of patients under the Ontario Review Board (ORB) between 2014 and 2015. In the analysis, we included patients with complete data on ACEs, self-harming behaviours, and a Psychopathy Checklist-Revised (PCL-R) score - a measure of psychopathic traits and their severity conducted during the reporting period. Mediation analysis was based on the Baron and Kenny approach, and sensitivity analysis was performed based on the types of ACEs. RESULTS: ​​​The sample population (n = 593) was made up of adults, with a mean age of 41.21 (± 12.35) years and were predominantly males (92.37%). While there was a partial mediating effect of psychopathy on the relationship between ACEs and incidents of self-harming behaviours in the past year, the mediation was complete in the relationship between ACEs and a lifetime history of self-harming behaviours. Following sensitivity analysis based on the types of ACE, the mediating effects were more attributed to specific ACEs, especially having experienced child abuse or having an incarcerated household member before 18 years. CONCLUSION: Among forensic patients in Ontario, psychopathy mediates​ ​the relationship between experiencing ACEs and engaging in self-harming behaviours. Effective intervention to mitigate self-harming behaviours in this population should consider the potential role of psychopathy, especially among individuals who have experienced ACEs involving a history of child abuse and a family who was incarcerated.

Enhancing Pre-Treatment Motivation Improves Forensic Mental Health Outcomes.

Despite evidence that psychological treatments benefit from pre-treatment intervention, there remains no published research on the value of including a pre-treatment intervention in forensic mental health settings. The present study aimed to address this gap by examining the effects of adding a brief motivational preparatory program (MPP) to standard forensic psychiatric care. The MPP was based on hope theory and motivational interviewing within a cognitive-behavioral therapy approach. MPP participants and a waitlist control group completed a battery of self-report measures of hope and motivation to change, which were compared with respect to risk, demographic, offence history, and outcome variables. There was a significant increase in client motivation for change after completing the MPP. Additionally, those who completed the MPP evidenced modest reductions in aggressive behavior, but significantly increased engagement in subsequent forensic treatment and programming.

Childhood Sexual Abuse by Women of Boys Who Go On to Sexually Offend: Review and Critical Analysis.

PURPOSE OF REVIEW: Sexual offending perpetrated by women has historically been overlooked and understudied, and the potentially unique impact of that abuse is even more so. RECENT FINDINGS: Women who have sexually offended against children typically do so against older boys, use little or no forms of force or coercion during the abuse, and are unlikely to be prosecuted or sentenced following the abuse. Boys whom women have sexually abused are unlikely to report or disclose the abuse that they have experienced, perhaps because social structures surrounding sexual abuse of boys by women are designed to minimize, excuse, or even encourage such sexual contact. The intersection of these unique features may help understand the role of childhood sexual abuse perpetrated by women in subsequent sexual offending among adult men. Men who have sexually offended experience high rates of childhood sexual abuse perpetrated by women. The relationship between experienced sexual abuse and subsequent perpetration of sexual abuse is neither linear nor causal; however, the characteristics associated with this form of abuse, such as non-disclosure and lack of sentencing, may contribute to adulthood sexual maladjustment and vulnerability to offending among men.

Self-harming behaviors and forensic system-related factors: an analysis of the Ontario review board database.

BACKGROUND: In Canada, ensuring public safety, and the safety and well-being of accused individuals under the jurisdiction of the provincial review board are very important. While previous studies have reported a significant risk of self-harming behaviors (non-suicidal self-injury and suicide attempt) in forensic psychiatric settings, no large population study has assessed any relationship between forensic system-related factors and self-harming behaviors. A better understanding of these factors can help clinicians implement protective measures to mitigate self-harming behaviors or actions. METHODS: Using the Ontario Review Board (ORB) database covering 2014-2015 period (n = 1211, mean age = 42.5 ± 13.37 years, males = 86.1%), we analyzed the prevalence and factors associated with self-harming behaviors, emphasizing the characterization of the forensic system-related factors (ORB status, legal status, type of offense, previous criminal history, and victim relationship). The relationships between the forensic system-related factors and self-harming behaviors were explored using five separate logistic regression models, controlling for clinical and sociodemographic characteristics. RESULTS: Approximately 4% of the individuals in the forensic system over the study period engaged in self-harming behaviors Among the studied patients, individuals determined to be unfit to stand trial and inpatients were significantly more likely to have self-harming behaviors. There was no significant relationship between the type of offence, victim relationship, and previous criminal history with self-harming behavior. CONCLUSION: Forensic psychiatry inpatients should have close observation, screening, monitoring, and individual tailored management strategies for self-harming behaviors. The findings of this study indicate that forensic system-related factors, especially those that pertain to the status of individuals in the forensic system (i.e., unfit to stand trial and being an inpatient) are more responsible for self-harming behaviors among forensic patients in Ontario.

The HARM models: Predicting longitudinal physical aggression in patients with schizophrenia at an individual level.

The prediction and prevention of aggression in individuals with schizophrenia remains a top priority within forensic psychiatric settings. While risk assessment methods are well rooted in forensic psychiatry, there are no available tools to predict longitudinal physical aggression in patients with schizophrenia within forensic settings at an individual level. In the present study, we used evidence-based risk and protective factors, as well as variables related to course of treatment assessed at baseline, to predict prospective incidents of physical aggression (4-month, 12-month, and 18-month follow-up) among 151 patients with schizophrenia within the forensic mental healthcare system. Across our HARM models, the balanced accuracy (sensitivity + specificity/2) of predicting physical aggressive incidents in patients with schizophrenia ranged from 59.73 to 87.33% at 4-month follow-up, 68.31-80.10% at 12-month follow-up, and 46.22-81.63% at 18-month follow-up, respectively. Additionally, we developed separate models, using clinician rated clinical judgement of short term and immediate violent risk, as a measure of comparison. Several modifiable evidence-based predictors of prospective physical aggression in schizophrenia were identified, including impulse control, substance abuse, impulsivity, treatment non-adherence, mood and psychotic symptoms, substance abuse, and poor family support. To the best of our knowledge, our HARM models are the first to predict longitudinal physical aggression at an individual level in patients with schizophrenia in forensic settings. However, it is important to caution that since these machine learning models were developed in the context of forensic settings, they may not be generalisable to individuals with schizophrenia more broadly. Moreover, a low base rate of physical aggression was observed in the testing set (6.0-11.6% across timepoints). As such, larger cohorts will be required to determine the replicability of these findings.

The Ontario Forensic Mental Health System: A Population-based Review.

OBJECTIVE: The purpose of this study was to increase the understanding of the Canadian forensic psychiatry system by providing a population-based overview of the Ontario forensic mental health system. METHODS: Data were collected on 1,240 accused adults who were subject to the jurisdiction of the Ontario Review Board (ORB) between 2014 and 2015. Archival data were retrieved from annual ORB hearing hospital reports for accused supervised by all nine adult forensic psychiatry facilities across Ontario. RESULTS: The sample included not criminally responsible (NCR; 91.6%) and unfit to stand trial (UST; 8.4%) accused. The majority of the sample was male (85.7%), single (70.1%), unemployed (63.6%), with a high school education (48.8%). Most were on a detention order (78.5%) and almost half were living in the community at the time of the report (48.8%). The majority had prior contact with psychiatric services (83.1%) and/or the criminal justice system (70.6%) before entering the forensic system. A history of elopement (31.5%) and inpatient aggression was high (60.6%). Most had a psychotic spectrum disorder (81.6%) and over half had a substance use disorder (57.2%) in the reporting year. A range of index offences was observed (69.9% violent, 20.3% general, 9.8% sexual), and the majority of the sample (61.0%) had an index offence that resulted in no injury or a minor injury to the victim. CONCLUSION: The Canadian forensic psychiatry system is comprised of a unique subset of justice-involved individuals. This study provides a detailed examination of accused who are subject to the jurisdiction of the ORB and provides key insight into risk factors associated with offending behaviour in this population. The results of this study will provide a framework for future studies examining the association between mental disorder and violence and the treatment trajectories for those in the forensic psychiatry system.

Public perceptions of psychiatric, justice-involved, and elderly populations during the COVID-19 pandemic.

The novel coronavirus disease (COVID-19) has had a significant global impact, with all countries facing the challenge of mitigating its spread. An unprecedented shortage of medical resources has raised concerns regarding allocation and prioritization of supplies, which may exacerbate social discrepancies for already vulnerable populations. As public opinion can impact healthcare policies, we aimed to characterize perceptions of psychiatric, forensic psychiatry, correctional, and elderly populations regarding COVID-19-related issues. This web-based study recruited participants (n = 583) from the general population in North America. The survey included perceptions of the pandemic, hypothetical scenarios on resource prioritization, and Likert scale questions. The majority of participants were cisgender female (72.7%), aged 31-74 years (80.0%), married (48.0%), retired (52.7%), resided in Canada (73.9%), had a college/university degree (50.9%) and had never worked in healthcare (66.21%). Most respondents reported not having a criminal history (95.88%), or a psychiatric disorder (78.73%). Perceptions of vulnerable populations were significantly different for resource allocation and prioritization (e.g., ventilator and vaccine resources, all p < 0.001). Healthcare workers and the elderly were commonly ranked the highest priority for resources, while forensic psychiatry and correctional populations were given the lowest priority. A high rate of disagreement was found for the more stigmatizing questions in the survey (all p < 0.0001). Our results suggest that perception from members of the general public in North America is aligned with current practices for resource allocation. However, individuals that already face social and health disparities may face additional opposition in decision-making for COVID-19 resources.

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

BACKGROUND: Actuarial 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. AIM: To 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. METHOD: Machine 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. RESULTS: Sexual 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. CONCLUSION: The 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.

The Relationship Between and Correlates of Problematic Sexual Behavior and Major Mental Illness.

While research has consistently found that general distress and psychopathology are not predictive of sexual recidivism, examination of specific syndromes and their relationship to offending has revealed a potentially more complicated relationship. One proposed mechanism for the mixed findings with respect to major mental illness and sexual offending may be the confound of neurological injury. As identified in Mann et al. (2010) work on psychologically meaningful risk factors, mental illness represents an area in need of more study given the indirect influence it may exert on risk. To this end, the current paper summarizes the study of the relationship between neurological injury, psychosis and problematic sexual behavior among two Canadian samples of forensic and civil psychiatric patients. In the first study we observed higher than expected rates of sexually-themed psychotic symptoms (45%) and problematic sexual behavior (PSB; 40%) among a combined group of forensic and civil psychiatric patients (n = 109). Indeed 70 percent of those individuals who engaged in PSB endorsed sexually-themed psychotic symptoms. While comorbidity is common amongst this group, brain injury appeared to represent a specific liability. Compared to those who did not engage in PSB, those who did were almost 4x (OR = 3.83) more likely to have a documented history of brain injury (e.g., traumatic and acquired brain injury, including fetal alcohol syndrome). In the second study we sought to replicate this finding in a larger forensic sample of 1,240. However, the recorded rates of brain injury were significantly less, such that no relationship to PSB was observed. Based on the mixed findings to date, including our own data, questions remain about the nature of a potential shared vulnerability for psychosis and PSB previously postulated. Among psychiatrically complex individuals who engage in PSB, understanding etiology and links to risk are helpful, but perhaps more importantly is attention to the mechanisms through which symptoms confer risk (e.g., problem solving, sexual disinhibition, social/intimacy deficits) and how best to treat and manage them.

Stigmatization of psychiatric and justice-involved populations during the COVID-19 pandemic.

Psychiatric and justice-involved populations are known to be stigmatized and particularly vulnerable to adverse outcomes during COVID-19. The increased attention toward vulnerable populations from healthcare authorities, the media, and the general public has made it critical to uncover any developing stigmatization toward these groups and the possible consequences. The prioritization of public safety and shift in the prioritization of resource allocation and service delivery could lead to a rise in negative perceptions toward these already stigmatized groups. Thus, it is imperative to consider how the unique characteristics of vulnerable groups may impact their physical and mental health as well as their care during this pandemic. In this paper, we describe the challenges that psychiatric, correctional, and forensic psychiatry populations have faced during COVID-19 and how a rise in stigmatization could lead to adverse outcomes. Specifically, we outline the influence of the media on public perceptions and how stigmatization may be reflected in the allocation of resources, policies, and related decision-making during COVID-19.

A preliminary evaluation of the effectiveness of dialectical behaviour therapy in a forensic psychiatric setting.

Dialectical behaviour therapy (DBT) is a therapy model incorporating elements of Eastern philosophies and cognitive behavioural principles. Originally designed for people struggling with chronic suicidality and borderline personality disorder (BPD), it has been adapted to treat complex, multi-diagnostic presentations, such as those in forensic mental health settings. To date, there has been little evaluation when the primary diagnosis is of psychosis. To explore the effectiveness of DBT, with patients, with multiple comorbidities, including psychosis, in a forensic psychiatric inpatient setting. A descriptive outcome study with a cohort of offender-patients in one specialist forensic mental health unit. Before and after treatment change scores were compared on anger, aggression, hopefulness, coping abilities, emotional intelligence, insight and subjective symptom severity scales, as well as staff-rated risk, and length of stay. Nine men and five women residents in one Canadian secure hospital completed a standard DBT programme, and self-ratings, over about 1 year. Scale scores indicated significantly increased insight and acknowledgment of problems. Apparently increased anger and vengeance scores were clinically associated. Independent staff ratings indicated reductions in risk and most patients achieved early release. This study provides support for extension of the use of DBT to offender-patients with psychosis among the complex mix in their presentation. It suggests that a randomised controlled trial with cost-benefit analysis is warranted, as well as further work, to promote understanding of mechanisms of effectiveness.

Implementation of risk assessment tools in psychiatric services.

Violence remains a major risk management concern in psychiatric services with implications on the safety and well-being of patients, staff, and the public. Serious physical and psychological consequences of violence involving property damage, bodily injuries, and threat to life have been reported in mental health services. Risk assessment tools are important safeguard measures; however, research on clinical implementation is presently limited. Structured professional judgment (SPJ) risk management tools that incorporate professional discretion with analytical understanding of evidence-based risk factors are widely accepted for risk assessment. However, clinical utility is suboptimal due to several barriers, including those related to the tool, the clinical setting, and resistance from health professionals. To better understand the challenges militating against optimal implementation of risk assessment tools, we reviewed and presented some lessons from the implementation of clinical practice guidelines on a general scale and our experience implementing an SPJ tool called Hamilton Anatomy of Risk Management across a variety of psychiatric services. In summary, the clinical utility of risk assessment tools improves if the tool is psychometrically sound, concise, consensus rated, time efficient, and practical for planning risk management. User feedbacks on the tool utility are also important to sustain implementation.

Assessing Paraphilic Interests Among Women Who Sexually Offend.

PURPOSE OF REVIEW: We examine the state of scientific research on the assessment of paraphilic interests among women who have committed sexual offences. RECENT FINDINGS: Research on the assessment of sexual interests in women using genital measures shows little evidence, overall, that women's genital responses are indicative of sexual interests. Some non-genital measures of sexual interest may be a valid indicator of age interests. Very few studies have focused on women who sexually offend. At this time, there is no validated measure that can be used to assess paraphilic interests among women who sexually offend. Much research is needed to determine if some measures (other than self-report) could validly assess a variety of sexual interests in women in general, and women who sexually offend in particular (e.g. interest in children, interest in sexual violence). This research is needed to determine if paraphilic interests are involved in women's motivation for sexual offending, and to determine if such interests are predictive of sexual recidivism.

Technological advances in the assessment of impulse control in offenders: A systematic review.

Deficits in impulse control have been linked to criminal offending, risk of recidivism, and other maladaptive behaviours relevant to the criminal justice system (e.g. substance use). Impulse control can be conceptualized as encompassing the broad domains of response inhibition and impulsive/risky decision-making. Advancements in technology have led to the development of computerized behavioural measures to assess performance in these domains, such as go/no-go and delay discounting tasks. Despite a relatively large literature examining these tasks in offenders, findings are not universally consistent. This systematic review aims to synthesize the literature using computerized neurocognitive tasks to assess two domains of impulse control in offenders: response inhibition and impulsive/risky decision-making. The review included 28 studies from diverse geographic locations, settings, and offender populations. The results largely support the general conclusion that offenders exhibit deficits in impulse control compared with non-offenders, with studies of response inhibition more consistently reporting differences than studies using impulsive and risky decision-making tasks. Findings are discussed in the context of contemporary neuroimaging research emphasizing dysfunction in prefrontal cortex as a key contributor to impulse control deficits in offenders.

Validating the Hamilton Anatomy of Risk Management-Forensic Version and the Aggressive Incidents Scale.

The Hamilton Anatomy of Risk Management-Forensic Version (HARM-FV) is a structured professional judgement tool of violence risk developed for use in forensic inpatient psychiatric settings. The HARM-FV is used with the Aggressive Incidents Scale (AIS), which provides a standardized method of recording aggressive incidents. We report the findings of the concurrent validity of the HARM-FV and the AIS with widely used measures of violence risk and aggressive acts, the Historical, Clinical, Risk Management-20, Version 3 (HCR-20V3) and a modified version of the Overt Aggression Scale. We also present findings on the predictive validity of the HARM-FV in the short term (1-month follow-up periods) for varying severities of aggressive acts. The results indicated strong support for the concurrent validity of the HARM-FV and AIS and promising support for the predictive accuracy of the tool for inpatient aggression. This article provides support for the continued clinical use of the HARM-FV within an inpatient forensic setting and highlights areas for further research.

Major Mental Illness in Those Who Sexually Abuse.

PURPOSE OF REVIEW: There is evidence showing an increasing prevalence of mental illness in those in conflict with the law. However, there are many factors affecting the detection, treatment, and management of criminals who are mentally ill. RECENT FINDINGS: Sex offenders with major mental illness present many challenges to those providing treatment and management services. For example, it is important to consider whether sexually offensive behavior is the cause of criminal behavior or whether it is reflective of an antisocial orientation. Recent evidence suggests it may help better understand and inform risk assessment and management. This paper will review the literature on mental illness among sexual offenders, present a typology to aid in the assessment, treatment, and management of sexual offender with mental illness, and highlight important considerations when providing treatment to sexual offenders with mental illness.

Incapacity of the Mind Secondary to Medication Misuse as a Not Criminally Responsible Defense.

The manifestations of disorders of the mind may play a role in the occurrence of criminal behavior. In the majority of the cases, the presence of a psychiatric disorder is cited as the reason that an individual was not fully aware of his behavior. However, other conditions, such as seizure disorders or hypoglycemia, have also been linked to an inability to understand the nature and consequences of one's actions. On occasion, these situations can be explained by a state of automatism that may be described as insane or noninsane. In this article, we describe the case of a 77-year-old man, suffering from Parkinson's disease, where the issue of criminal responsibility associated with incapacity of the mind secondary to medication misuse was raised. We elaborate on the thinking behind this opinion and the implications according to Canadian law. Although the legal outcome of this case is specific to our jurisdiction, the clinical implication may be common to any patient suffering from a similar condition and may inform physicians, families, and lawyers.

Therapist awareness and responsibility in working with sexual offenders.

The article aims to address the ethical implications of therapist reactions to sexual offender treatment and, in doing so, increase awareness and understanding of the interaction between the clinician and the challenges of working with sexual offenders. The effects of providing psychological services in general, and to sexual offenders specifically, are reviewed, including the impact on services provided. Practice implications are also discussed as the authors consider the negative effects (e.g., burnout) that therapists experience due to treatment quality and the ethical issues and responsibilities surrounding clinical reactions. Finally, the authors summarize research on self-care and practice recommendations for effectively and ethically working with sexual offenders.

A description of sexual offending committed by Canadian teachers.

The aim of this investigation was to describe teachers who sexually offend against youth and the circumstances related to these offenses. Archival Violent Crime Linkage Analysis System reports were obtained from the Royal Canadian Mounted Police, and demographic and criminal characteristics for the offender, as well as information about the victim and offense, were selected for analyses. A descriptive approach was used to analyze the qualitative reports for a group of 113 Canadian sexual offenders between 1995 and 2002. The results provide a description of adult male teachers who offended within their position of trust as well as offense and victim characteristics.

Clerics who commit sexual offenses: offender, offense, and victim characteristics.

The aim of this investigation was to undertake an exploratory analysis of clerics who sexually offend and the circumstances related to these offenses. Thirty-three adult male religious leaders who had been charged with a sexual offense against a child or adolescent were included in the study. This study examined descriptive information about offenders, their victims, as well as characteristics of the crimes. Notable trends included the following: religious leaders tended to offend against boys living with both parents, the offense often took place at the clergy's residence, and the offense involved fondling the victim. The study also compared offenders with single versus multiple victims on crime variables and differences were noted with respect to victim access.
