Correlates of offense recidivism in patients with schizophrenia

Recidivism among prisoners with severe mental disorders

Introduction

Mental disorders are common among prison inmates, with a high rate of recidivism found among those with severe mental disorders. In Japan, the number of inmates with mental disorders has been increasing with the increasing rate of recidivism. Prisoners need an uninterrupted connection to post-release support to prevent them from being incarcerated again. This study identified inmates diagnosed with mental disorders whose recidivism had recently increased to investigate recidivism among inmates with severe mental disorders and the risk factors for reincarceration.

Methods

This study included 148 prisoners released from the Medical Correction Center in East Japan. Clinical diagnoses were coded using the World Health Organization's International Classification of Diseases, Tenth Revision. Risk factors focusing on the central eight items were categorized, and recidivism within 3 years of release was investigated.

Result

Overall, the recidivism rate was 29.7%, with the risk of recidivism increasing by 170% in inmates with multiple incarcerations. A diagnosis of intellectual disability increased the risk of recidivism by 176%. Patients with schizophrenia were consistently less likely to recidivate than patients with other disorders.

Conclusion

Intellectual disability was identified as a risk factor for recidivism, as was multiple incarcerations. These prisoners may not be connected to medical and social services and thus may not be receiving appropriate assistance. Patients with schizophrenia might be more likely to be connected to medical care and receive support after release. Further research should be conducted using these findings to prevent recidivism among inmates with mental disorders.

Aggressive behaviour in antipsychotic-naive first-episode schizophrenia patients, their unaffected siblings and healthy controls

AIM

While patients with schizophrenia are more likely to be victims rather than perpetrators of aggressive behaviour, prior research has shown increased rates of aggressive behaviours in these patients that appear very early in the course of illness. We aimed to assess aggression in antipsychotic-naive first-episode schizophrenia patients, their healthy siblings, and controls; and to investigate correlates of aggression in the patients group.

METHODS

Patients (N = 55), siblings (N = 55) and healthy controls (N = 71) were evaluated on Buss and Perry Aggression Questionnaire (AQ), Life History of Aggression (LHA), Barratt Impulsiveness Scale, and Levenson Self-Report Psychopathy Scale. Age, gender and substance use were regarded as covariates, and differences between the three groups were evaluated using analysis of covariance. Hierarchical regression was performed to determine which variables were associated with aggression level in the patients group.

RESULTS

The Tukey multiple comparison test showed that both patients (p < .001) and siblings (p = .023) scored higher on the LHA Aggression than controls. Siblings scored higher than controls (p = .010) for the Anger subscale of the AQ. Patients scored significantly higher than controls in the three impulsiveness dimensions; whereas siblings scored higher than controls in the motor (p = .023) and non-planning (p = .004) dimensions. Multivariate analyses showed that, after controlling for confounders, only attentional impulsiveness (β = .446, p = .0244) and psychopathy traits (β = .359, p = .010) helped predict AQ total scores among patients.

CONCLUSION

Aggression and some of its risk factors including impulsiveness are likely to be trait variables that might provide important vulnerability markers for people at heightened risk of developing psychosis.

Model Building in Forensic Psychiatry: A Machine Learning Approach to Screening Offender Patients with SSD

Today’s extensive availability of medical data enables the development of predictive models, but this requires suitable statistical methods, such as machine learning (ML). Especially in forensic psychiatry, a complex and cost-intensive field with risk assessments and predictions of treatment outcomes as central tasks, there is a need for such predictive tools, for example, to anticipate complex treatment courses and to be able to offer appropriate therapy on an individualized basis. This study aimed to develop a first basic model for the anticipation of adverse treatment courses based on prior compulsory admission and/or conviction as simple and easily objectifiable parameters in offender patients with a schizophrenia spectrum disorder (SSD). With a balanced accuracy of 67% and an AUC of 0.72, gradient boosting proved to be the optimal ML algorithm. Antisocial behavior, physical violence against staff, rule breaking, hyperactivity, delusions of grandeur, fewer feelings of guilt, the need for compulsory isolation, cannabis abuse/dependence, a higher dose of antipsychotics (measured by the olanzapine half-life) and an unfavorable legal prognosis emerged as the ten most influential variables out of a dataset with 209 parameters. Our findings could demonstrate an example of the use of ML in the development of an easy-to-use predictive model based on few objectifiable factors.

Child abuse and aggressiveness in individuals diagnosed with schizophrenia in Lebanon

OBJECTIVES

To identify individual and clinical risk factors of aggressiveness, including exposure to different forms of childhood trauma, in a sample of Lebanese patients with schizophrenia.

METHODS

A total of 131 patients diagnosed with schizophrenia participated in this cross-sectional study.

RESULTS

Higher physical (Beta = 0.24, p < 0.001) and sexual (Beta = 0.29, p = 0.003) abuse, alcohol drinking (Beta = 1.46, p = 0.008), having a history of head trauma (Beta = 1.10, p = 0.041), and male gender (Beta = -1.59, p = 0.009) were significantly associated with higher mean aggression scores.

PRACTICAL IMPLICATIONS

Our investigation of the factors linked to aggressiveness in patients with schizophrenia complement those of earlier findings, showing that the relationship between interacting individual and environmental risk factors and later aggressiveness is quite complex, and needs further longitudinal and prospective studies.

Criminal behavior and mental illness in the Arab world

Numerous studies have highlighted significant correlations between major psychiatric disorders and criminal behavior. However, the plethora of literature on criminality among patients with major psychiatric disorders originated in the West. The objective of the present paper is to review criminal behavior among individuals with mental illness in Arab countries. Attributes of individuals assessed by forensic psychiatric committees and identifying various aspects that may reinforce criminality among individuals with mental illness were considered. Following the PRISMA guidelines, a systematic review of literature from three databases (Scopus, PubMed, and Web of Science) was carried out. A total of 20 articles were included. The publications span between 1975 and 2020 and originated in seven different Arab countries including Egypt, Kuwait, Iraq, Saudi Arabia, Tunisia, Jordan, and Algeria. Individuals evaluated by forensic psychiatric committees were predominantly males. Excluding substance use disorder, psychotic disorders were the most commonly diagnosed disorders among individuals evaluated by forensic psychiatry committees. Concerning schizophrenia, concomitant substance use and nonadherence to therapy were significantly associated with increased criminality. The review demonstrates that substance use is certainly linked to violence. There is a significant association between mental illness and criminal behavior. Therefore, awareness of different characteristics and risk factors behind criminal behavior among mentally ill offenders could allow us to design and implement effective preventative measures. The Arab's contribution in this field of forensic psychiatry is relatively small. Indeed, further investigation and contributions from the Arab world are required.

Psychopathy, temperament, and character dimensions of personality as risk determinants of criminal recidivism in schizophrenia patients

There is considerable evidence on the role of personality traits in the risk of criminal recidivism among schizophrenia patients, besides conventional risk factors. We evaluated the effects of psychopathy and biopsychosocial personality model on general criminal recidivism in schizophrenia patients. Ninety-four male DSM-5 diagnosed schizophrenia patients were recruited and classified into three groups according to the number of offenses since diagnosis: reoffenders (n = 32), Initial offenders (n = 31), and nonoffenders (n = 31). All subjects were evaluated by the Turkish versions of Psychopathy Checklist-Revised (PCL-R) and Temperament and Character Inventory-Revised (TCI-R). In Reoffenders, all subscale scores of PCL-R and Novelty seeking were the highest, while Self-directedness and Cooperativeness were the lowest. PCL-R Total, Factor 1 and Factor 2 positively correlated with Novelty Seeking, and negatively correlated with Harm Avoidance, Self-directedness, and Cooperativeness in offender patients. For criminal recidivism in offender patients, high PCL-R Total and Novelty Seeking, low Harm Avoidance, Self-directedness, and Cooperativeness, being unmarried, presence of childhood adversity, and younger age at the first offense were found to be significant predictors in univariate analyses; multivariate regression models revealed PCL-R Total and Persistence as the only significant predictors. These results suggest that certain dimensional personality evaluations combined with potential historical, clinical, and forensic risk factors can be employed in forensic settings to screen offender schizophrenia patients at an increased risk of recidivism and to take necessary precautions against further criminal behavior.

Professionalising release management for mentally disordered perpetrators: Benefits in terms of recidivism rates-Results from a study within the Austrian prison system

BACKGROUND

In Austria, mentally ill perpetrators not guilty for reasons of insanity are committed into a custodial measure to receive treatment. The rate of these detainees returning after their conditional release because of reoffending or revocation decreased significantly over a period of 15 years.

AIMS

This study aims at examining this system and the adjustments made over a period of 10 years, in order to identify changes responsible for the observable decline of the recidivism rate.

METHOD

Therefore, a quantitative study of 807 prison and court files was conducted, extracting information concerning former detainees either released in 2001 & 2002 (n = 67) or 2011 & 2012 (n = 134) and subsequently comparing the groups. Additionally, expert interviews were conducted.

RESULTS

As one major change, the data revealed improvements regarding the preparation and management of the time on parole. The possibility for detainees to test their readiness for life outside the confinement through temporary interruptions of custody was enhanced, as were post-release housing opportunities in care facilities. Additionally, the courts issued more directives concerning measures such as medication or abstinence from alcohol.

CONCLUSION

Concerning mentally ill offenders, this study highlights the importance of a comprehensive preparation and management of the conditional release, providing support and treatment as well as a certain level of control.

Hospital treatment of persons found not guilty by reason of insanity

After being found not guilty by reason of insanity (NGRI), individuals are typically admitted to a secure forensic hospital for evaluation and treatment. This patient population can pose a challenge to clinicians in the hospital setting due to significant violence risk, complex psychiatric presentations, and scrutiny from oversight boards and the public. This article reviews the scientific literature around several key aspects of hospital-based treatment of insanity acquittees, including the management of inpatient aggression, the provision of specific treatments to acquittees, the assessment of violence risk and readiness for release, and the process of community transition. The authors conclude that the existing literature is heavily weighted toward the study of risk assessment and recidivism, with relatively little attention paid to the study of therapeutic modalities and recovery-oriented care in this population.

Childhood trauma, psychiatric disorders, and criminality in women: Associations with serum levels of brain-derived neurotrophic factor

Psychiatric disorders and childhood trauma are highly prevalent in female inmates. Brain-derived neurotrophic factor (BDNF) plays a number of roles in neuronal survival, structure, and function. Data in the literature suggest that it is a neurobiological substrate that moderates the impact of childhood adversities on the late expression of psychiatric disorders. The aim of this study was to determine whether five childhood trauma subtypes-physical abuse, sexual abuse, emotional abuse, physical neglect, and emotional neglect-are associated with adult psychiatric disorders, BDNF levels, and criminality among incarcerated women. This was a cross-sectional study involving a consecutive sample of 110 women, divided into three groups of women (forensic - mentally ill who committed crimes, clinical psychiatric inpatients and healthy controls). The Childhood Trauma Questionnaire and the Mini-International Neuropsychiatric Interview-Plus were applied in the whole sample, and BDNF levels were measured in a sub-sample of 54 women. The rates of mental illness and childhood trauma were high in the forensic group. Emotional abuse was higher in the clinical and forensic groups than in the healthy control group. Lower BDNF levels were associated with emotional abuse in the forensic group as well as with sexual abuse in the healthy control group. After multinomial logistic regression, lower levels of BDNF, higher levels of emotional abuse and the presence of familial offense were considered factors related to clinical psychiatric group. The results of this study underscore the idea that BDNF may be an important factor related to the development of diseases and criminality in women who are victims of childhood trauma, becoming a possible biological marker.

Monitoring and improving antipsychotic adherence in outpatient forensic diversion programs

Outpatient diversion programs present an opportunity for severely mentally ill defendants to receive psychiatric treatment and have alleged offenses dismissed by the court. Moreover, the successful completion of pretrial diversion is associated with fewer post-program arrest and jail days. The target patient population for such programs is typically people with schizophrenia spectrum disorders, but the care of such patients in outpatient settings presents challenges for monitoring treatment fidelity, specifically antipsychotic adherence, as low adherence rates are associated with increased rates of recidivism. Presented here is a review of evidence-based strategies that must be employed to track antipsychotic adherence in outpatient diversion programs, including pill counts, use of long-acting injectable antipsychotics, and determination of plasma antipsychotic levels to assess adherence and the adequacy of antipsychotic treatment. Antipsychotic therapy remains the foundation of schizophrenia treatment, but only through the use of all available modalities can clinicians maximize the odds that schizophrenia patients in pretrial diversion maintain psychiatric stability and successfully complete mental health court mandates.
