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

What do we know now about evidence-based treatment for psychosis and aggressive behaviour or criminality that we did not know when community care was implemented?

PURPOSE

Community care replaced institutional care for people with psychosis without guidance about what constituted effective treatment. In a Swedish birth cohort, many of those who developed schizophrenia or bipolar disorder as community care was being implemented were subsequently convicted of violent and non-violent crimes. Studies from other countries that were implementing community care at this time also reported elevated proportions of patients acquiring criminal convictions. Since community care was first implemented, much has been learned about factors that promote and treatments that limit aggressive/antisocial behaviour/criminality (AABC) among people with psychosis. Without the benefit of this knowledge, did mental health policy and practices that were in place as the asylums were closed inadvertently contribute to criminality?

MATERIAL AND METHODS

This article provides a narrative review of current evidence of effective treatments and management strategies to reduce AABC among patients with psychosis.

RESULTS

Reductions in AABC are associated with stable contact with psychiatric services, second-generation antipsychotic medication, clozapine for patients with schizophrenia and elevated levels of hostility and/or a history of childhood conduct disorder, abstinence from substances, avoidance of trauma, and constant monitoring of both illness symptoms and AABC.

CONCLUSIONS

Failure to adopt evidence-based practices allows the problem of AABC to persist, prevents patients from experiencing independent, safe, community tenure, and puts those around them at risk. Many challenges remain, including implementing effective assessment and interventions at first-episode and convincing patients with antisocial attitudes and behaviours to participate in treatment programs to reduce AABC and to learn prosocial behaviours.

The burden for clinical services of persons with an intellectual disability or mental disorder convicted of criminal offences: A birth cohort study of 14,605 persons followed to age 64

BACKGROUND

Intellectual disability (ID), schizophrenia spectrum disorder (SSD), bipolar disorder (BD), substance use disorder (SUD), and other mental disorders (OMDs) are associated with increased risks of criminality relative to sex-matched individuals without these conditions (NOIDMD). To resource psychiatric, addiction, and social services so as to provide effective treatments, further information is needed about the size of sub-groups convicted of crimes, recidivism, timing of offending, antecedents, and correlates. Stigma of persons with mental disorders could potentially be dramatically reduced if violence was prevented.

METHODS

A birth cohort of 14,605 persons was followed to age 64 using data from Swedish national health, criminal, and social registers.

RESULTS

Percentages of group members convicted of violence differed significantly: males NOIDMD, 7.3%, ID 29.2%, SSD 38.6%, BD 30.7%; SUD 44.0%, and OMD 19.3%; females NOIDMD 0.8%, ID 7.7%, SSD 11.2%, BD 2.4%, SD 17.0%, and OMD 2.1%. Violent recidivism was high. Most violent offenders in the diagnostic groups were also convicted of non-violent crimes. Prior to first diagnosis, convictions (violent or non-violent) had been acquired by over 90% of the male offenders and two-thirds of the female offenders. Physical victimization, adult comorbid SUD, childhood conduct problems, and adolescent substance misuse were each associated with increased risks of offending.

CONCLUSION

Sub-groups of cohort members with ID or mental disorders were convicted of violent and non-violent crimes to age 64 suggesting the need for treatment of primary disorders and for antisocial/aggressive behavior. Many patients engaging in violence could be identified at first contact with clinical services.

Forensic mental health issues for women in contact with the criminal justice system

OBJECTIVE

This review demonstrates that women who encounter the Australian criminal justice system include some of the most disadvantaged and mentally unwell people in society, particularly Aboriginal women. Women in custody are a heterogeneous group and have different psychosocial needs when compared to male prisoners.

CONCLUSION

The approaches to female offending must address their significant psychosocial and mental health issues at every point of contact with the criminal justice system, be culturally informed and specifically address Indigenous overrepresentation.

Aggressive Incidents by Incarcerated People With Psychiatric Illness and Their Relationship With Psychiatric Symptoms

AIM

A prospective design was used to investigate the relationship of current psychiatric symptoms of incarcerated people with serious mental illness (SMI) and aggressive behavior on a penitentiary ward for crisis intervention.

METHODS

One hundred sixty detainees with SMI, detained in a high-security penitentiary psychiatric facility, were screened every 2 weeks with the Brief Psychiatric Rating Scale-Extended (BPRS-E) by trained clinicians, to ensure that the data on psychiatric symptoms were up-to-date. Aggressive behavior was registered with the Staff Observation Aggression Scale-Revised. A binary logistic regression analysis was performed to examine the relationships between factor scores of the BPRS-E and aggressive behavior.

RESULTS

Significant relationships between the BPRS-E factor hostility, antisocial traits, and aggressive incidents were found, but not between the positive symptoms or manic factor scores and aggressive incidents.

DISCUSSION

Symptoms of SMI measured with the BPRS-E did not help to explain the occurrence of aggressive behavior. This is not in line with what is commonly found. The implication is that it can be expected that this population will display aggressive behavior but that symptoms do not help in predicting when this will occur. In addition, hostility and antisocial traits were related to aggressive behavior. For this specific population, an interactional approach might be more effective in the management of aggression than treatment of symptoms of SMI.
