Ethnic variations regarding clinical profiles and symptom representation in prisoners with psychotic disorders

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.

Exploring Similarities and Differences of Non-European Migrants among Forensic Patients with Schizophrenia

Migrants diagnosed with schizophrenia are overrepresented in forensic-psychiatric clinics. A comprehensive characterization of this offender subgroup remains to be conducted. The present exploratory study aims at closing this research gap. In a sample of 370 inpatients with schizophrenia spectrum disorders who were detained in a Swiss forensic-psychiatric clinic, 653 different variables were analyzed to identify possible differences between native Europeans and non-European migrants. The exploratory data analysis was conducted by means of supervised machine learning. In order to minimize the multiple testing problem, the detected group differences were cross-validated by applying six different machine learning algorithms on the data set. Subsequently, the variables identified as most influential were used for machine learning algorithm building and evaluation. The combination of two childhood-related factors and three therapy-related factors allowed to differentiate native Europeans and non-European migrants with an accuracy of 74.5% and a predictive power of AUC = 0.75 (area under the curve). The AUC could not be enhanced by any of the investigated criminal history factors or psychiatric history factors. Overall, it was found that the migrant subgroup was quite similar to the rest of offender patients with schizophrenia, which may help to reduce the stigmatization of migrants in forensic-psychiatric clinics. Some of the predictor variables identified may serve as starting points for studies aimed at developing crime prevention approaches in the community setting and risk management strategies tailored to subgroups of offenders with schizophrenia.

Foreign National Patients in German Prison Psychiatry

INTRODUCTION

Over the past few years, the share of foreign national prisoners in the European and American justice systems has increased at a disproportionately high rate, yet studies on mental health issues among this diverse group are rare. Recent research suggests a range of factors leading to mental health vulnerability in foreign national prisoners, including language barriers, isolation, cultural misunderstanding, and legal standing. Relevant findings of topic-related studies indicate that under-referral to mental health services due to missed or misinterpreted symptoms is a major risk for foreign national prisoners.

AIMS

We aimed to investigate the disparities regarding the percentage of foreign national patients who were treated in high-security hospitals compared to the psychiatric ward of prison hospitals-after adjusting for diagnosis, age, marital status, and substance abuse. We hypothesized that foreign national patients were underrepresented in compulsory, high-security mental health care. We also aimed to explore citizenship-related institutional disparities concerning diagnoses and self-harmful behavior.

METHOD

From 2010 to 2015, data collected from high-security hospitals in the federal state of Baden-Wurttemberg and the psychiatric ward of a Berlin prison hospital was evaluated by comparing nationality, diagnosis, and self-harm using Fisher's exact test and χ²-test. The odds ratios for citizenship-related differences in diagnosis and institution of treatment were evaluated by using logistic regression.

RESULTS

Mentally ill foreign national patients were significantly less likely to be treated in high-security hospitals rather than prison hospital psychiatry (adjusted for diagnosis, age at admission, marital status, and substance abuse; adjusted OR = 0.5). Foreign nationals and Germans in prison hospital psychiatry showed no significant disparities in diagnosis; however, in high-security hospitals, foreign nationals were more likely to have been diagnosed with schizophrenia/psychotic or neurotic/stress-related disorders and were less likely to have been diagnosed with personality disorders than German patients. Additionally, foreign nationals were more likely to commit self-harm than Germans in prison hospital psychiatry, but significant citizenship-related differences could not be verified in high-security hospital patients.

CONCLUSION

Treatment conditions of foreign national patients in prison psychiatry must be improved. To achieve this, the psychiatric assessment and (mental) health-related aspects of these patients should be further investigated.
