Motivational Influences and Trajectories to Violence in the Context of Major Mental Illness

Personality disorders and schizophrenia spectrum disorders in the Italian forensic psychiatric population: clinical features, pattern of violence and treatment

Starting in 2015, the Residencies for Execution of Security Measures (REMS) became the place of treatment and care for dangerous offenders who were acquitted due to a mental disorder in Italy. Schizophrenia spectrum disorders (SSD) and personality disorders (PD) are the most common psychiatric disorders among REMS patients. This study aimed to identify and describe potential clinical, therapeutic, and criminal-related differences in REMS patients with SSD and PD. A sample of 528 REMS patients extracted from a previous observational retrospective study underwent secondary analysis. The group of PD patients (n = 150) comprised more females (p < 0.001) and had a higher frequency of substance abuse (p < 0.001) than the SSD group (n = 378). The SSD group was more frequently admitted to the REMS due to homicide/attempted homicide (p < 0.001). Among SSD patients, we found a higher recognition of criminal irresponsibility (p < 0.001). Patients with PD were more likely to engage in violent behavior in the REMS than their SSD counterparts (p < 0.001). Patients with SSD were more likely to receive antipsychotic polypharmacy (p < 0.05) and a higher dose of antipsychotics (p < 0.001). These initial results provide empirical evidence to support the need for personalized forensic treatment paths.

Serious Mental Illness and Sexual Offending in Forensic Psychiatric Patients

The role of serious mental illness among those who sexually offend is not well understood. We investigated clinical and risk-related areas of difference between male forensic psychiatric patients with (n = 86) and without (n = 245) a sexual offense history, including the age at which indications of mental disorder and criminal offending first emerged, from a registry of Ontario patients adjudicated Not Criminally Responsible on account of Mental Disorder (NCRMD) from 1999-2012. We further explored motivations for offending among a subset of patients deemed NCRMD for a sexual offense specifically (n = 41). While no differences were found in the age onset of illness or offending across those with and without a sexual offending history, the former group was rated as having higher levels of historical/static risk for violence. Forensic patients with a sexual offense history were also more likely to offend against a stranger, and less likely to offend against a family member. Sexual index offenses were psychotically-motivated in the majority of cases, but with a meaningful proportion appearing to reflect criminogenic motivations, especially substance use and paraphilic interests. Results suggest greater similarity than difference among forensic patients with and without a sexual offense history, but also highlight an important divergence from the literature showing that victims of sexual offenses are frequently known to the individual committing them.

Patterns and Predictors of Reincarceration among Prisoners with Serious Mental Illness: A Cohort Study: Modèles et prédicteurs de réincarcération chez les prisonniers souffrant de maladie mentale grave : Une étude de cohorte

BACKGROUND

A small proportion of people who have serious mental illness and rapid and frequent incarcerations account for a disproportionate amount of overall service use and cost. It is important to describe such individuals, so that services can respond more effectively.

METHODS

We investigated a cohort of 4,704 incarcerated men and women who were discharged from a correctional mental health service and followed for a median of 535 days. We investigated social, clinical, demographic, and offense characteristics as predictors of return to the service using Cox survival analyses. Secondly, we characterized individuals as high-frequency service users as those who had 3 or more incarcerations during a 1-year period and investigated their characteristics.

RESULTS

We found that a higher rate of return to custody was associated with schizophrenia spectrum/bipolar affective disorder (BPAD), personality disorder traits, crack cocaine and methamphetamine use, and unstable housing. Charges of theft/robbery and breach of probation were also positively associated, and sex assault was negatively associated with return to custody. Within a 1-year time period, we found 7.2% of individuals were high-frequency service users, which accounted for 19.5% of all reincarcerations.

CONCLUSION

Identification of the characteristics of those with mental illness in custody, especially those who have high-frequency returns to custody, may provide opportunity to target resources more effectively. The primary targets of intervention would be to treat those with schizophrenia/BPAD and substance use problems, particularly those using stimulants, and addressing homelessness. This could reduce the problem of repeated criminalization of the mentally ill and reduce the overall incarceration rate.
