Characteristics of patients who are violent to staff and towards other people from a community mental health service in South East England

Aggressive behaviour of psychiatric patients with mild and borderline intellectual disabilities in general mental health care

PURPOSE

Little is known about the associations between mild intellectual disability (MID), borderline intellectual functioning (BIF) and aggressive behaviour in general mental health care. The study aims to establish the association between aggressive behaviour and MID/BIF, analysing patient characteristics and diagnoses.

METHOD

1174 out of 1565 consecutive in-and outpatients were screened for MID/BIF with the Screener for Intelligence and Learning Disabilities (SCIL) in general mental health care in The Netherlands. During treatment, aggressive behaviour was assessed with the Staff Observation Aggression Scale-Revised (SOAS-R). We calculated odds ratios and performed a logistic and poisson regression to calculate the associations of MID/ BIF, patient characteristics and diagnoses with the probability of aggression.

RESULTS

Forty-one percent of participating patients were screened positive for MID/BIF. Patients with assumed MID/BIF showed significantly more aggression at the patient and sample level (odds ratio (OR) of 2.50 for aggression and 2.52 for engaging in outwardly directed physical aggression). The proportion of patients engaging in 2-5 repeated aggression incidents was higher in assumed MID (OR = 3.01, 95% CI 1.82-4.95) and MID/BIF (OR = 4.20, 95% CI 2.45-7.22). Logistic regression showed that patients who screened positive for BIF (OR 2,0 95% CL 1.26-3.17), MID (OR 2.89, 95% CI 1.87-4.46), had a bipolar disorder (OR 3.07, 95% CI 1.79-5.28), schizophrenia (OR 2.75, 95% CI 1.80-4.19), and younger age (OR 1.69, 95% CI 1.15-2.50), were more likely to have engaged in any aggression. Poisson regression underlined these findings, showing a SCIL of 15 and below (β = 0.61, p<0.001) was related to more incidents.

CONCLUSIONS

We found an increased risk for aggression and physical aggression in patients with assumed MID/BIF. We recommend screening for intellectual functioning at the start of treatment and using measures to prevent and manage aggressive behaviour that fits patients with MID/BIF.

The Link Between Cannabis Use and Violent Behavior in the Early Phase of Psychosis: The Potential Role of Impulsivity

INTRODUCTION

Recently, the literature has shown that Cannabis Use (CU) was a risk factor for Violent Behavior (VB) in patients with psychosis, and those in the early phase of psychosis (EPP). These findings are relevant because of the high prevalence of CU in this EPP, and the potential for prevention during this phase of illness. However, there is still a lack of clear explanations, supported by empirical evidence, about what underlies the link between CU and VB against other.

METHOD

This viewpoint reviews the scientific literature on the link between CU and VB, and the involvement of impulsivity in this relationship. This last point will be addressed at clinical and neurobiological levels.

RESULTS

Recent studies confirmed that CU is particularly high in the EPP, and is a risk factor for VB in the EPP and schizophrenia. Studies have also shown that impulsivity is a risk factor for VB in psychosis, is associated with CU, and may mediate the link between CU and VB. Research suggests a neurobiological mechanism, as CU affects the structures and function of frontal areas, known to play a role in impulsive behavior.

CONCLUSION

Scientific evidence support the hypothesis of an involvement of impulsivity as a variable that could mediate the link between CU and aggression, particularly, when CU has an early onset. However, this hypothesis should be confirmed with longitudinal studies and by taking into account confounding factors. The studies highlight the relevance of early prevention in the EPP, in addition to interventions focusing on psychotic disorders.

Trajectories of Dynamic Risk Factors as Predictors of Violence and Criminality in Patients Discharged From Mental Health Services: A Longitudinal Study Using Growth Mixture Modeling

Background: Individuals with severe mental illnesses are at greater risk of offenses and violence, though the relationship remains unclear due to the interplay of static and dynamic risk factors. Static factors have generally been emphasized, leaving little room for temporal changes in risk. Hence, this longitudinal study aims to identify subgroups of psychiatric populations at risk of violence and criminality by taking into account the dynamic changes of symptomatology and substance use. Method: A total of 825 patients from the MacArthur Violence Risk Assessment Study having completed five postdischarge follow-ups were analyzed. Individuals were classified into outcome trajectories (violence and criminality). Trajectories were computed for each substance (cannabis, alcohol, and cocaine, alone or combined) and for symptomatology and inputted as dynamic factors, along with other demographic and psychiatric static factors, into binary logistic regressions for predicting violence and criminality. Best predictors were then identified using backward elimination, and receiver operator characteristic (ROC) curves were calculated for both models. Results: Two trajectories were found for violence (low versus high violence). Best predictors for belonging in the high-violence group were low verbal intelligence (baseline), higher psychopathy (baseline) and anger (mean) scores, persistent cannabis use (alone), and persistent moderate affective symptoms. The model's area under the curve (AUC) was 0.773. Two trajectories were also chosen as being optimal for criminality. The final model to predict high criminality yielded an AUC of 0.788, retaining as predictors male sex, lower educational level, higher score of psychopathy (baseline), persistent polysubstance use (cannabis, cocaine, and alcohol), and persistent cannabis use (alone). Both models were moderately predictive of outcomes. Conclusion: Static factors identified as predictors are consistent with previously published literature. Concerning dynamic factors, unexpectedly, cannabis alone was an independent co-occurring variable, as well as affective symptoms, in the violence model. For criminality, our results are novel, as there are very few studies on criminal behaviors in nonforensic psychiatric populations. In conclusion, these results emphasize the need to further study the predictors of crime, separately from violence and the impact of longitudinal patterns of specific substance use and high affective symptoms.

Violence committed against nursing staff by patients in psychiatric outpatient settings

Violence against nurses has increased particularly in psychiatric outpatient settings as psychiatric care shifts from being inpatient-based to being outpatient-based. Violence is a complex phenomenon that must be explored in different psychiatric nursing environments and settings. Violence in psychiatric outpatient settings should especially be explored as violence in this context has scarcely been examined. The aim of this systematic review was to elucidate violence committed against nursing staff by patients in adult psychiatric outpatient settings, based on reports from previous studies. A literature search was conducted in the CINAHL (EBSCO), Ovid MEDLINE, and PsycARTICLES (Ovid) databases. Fourteen studies emerged after the selection and quality assessment process. These studies indicated that violence in psychiatric outpatient settings is a multidimensional phenomenon comprising the reasons for, forms of, and consequences of violence. Reasons for violence could be related to the patient as well as to nursing staff. In psychiatric outpatient settings, verbal violence was the most common form of violence, and violence most frequently led to psychological consequences for nursing staff. The findings of this review highlight the importance of nursing staff developing skills and interventions for managing different kinds of violent situations. Given the multidimensional consequences of violence, attention must be given to the occupational well-being and coping ability of nursing staff at work. Furthermore, it would be worthwhile to compare cultural and intercountry differences of violent exposures in psychiatric outpatient settings.

Violence exposure and resulting psychological effects suffered by psychiatric visiting nurses in Japan

WHAT IS KNOWN ON THE SUBJECT?: There is a developing body of research on violence in healthcare workplaces. Although psychiatric visiting nurses (PVNs) are an important group of professionals who provide medical services for people with mental disorders live in the community, little is known about the experiences and characteristics of violence exposure among PVNs, or the characteristics and work situations of PVNs related to violence exposure. WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE?: Approximately 40% of participants were exposed to violence during the previous 12 months; approximately 50% had been exposed during their PVN careers in PVN settings. The most frequent violence was verbal abuse. Longer career length as a PVN and greater number of visits per month were both positively associated with verbal abuse during the previous 12 months. Twenty-eight of the 34 participants (83%) who completed the IES-R-J survey had some residual psychological distress, and two (6%) had a potentially high risk of posttraumatic stress disorder. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: In devising policies and strategies against violence, PVN organizations and administrators should consider the characteristics of the violence, especially verbal abuse, as well as the characteristics and work situations of PVNs that are related to verbal abuse. Furthermore, they might provide relevant information on violence in PVN settings within their violence-prevention manuals or education. It would be important to provide support and to construct a safe workplace environment for PVNs who are experiencing residual psychological distress.

ABSTRACT

Introduction Psychiatric visiting nurses (PVNs) play a crucial role by providing medical services for community-living individuals with mental disorders in Japan. However, little is known about violence towards PVNs. Aim This cross-sectional study investigated violence during visits and the resulting psychological effects for PVNs. Methods PVNs were assessed using a violence exposure questionnaire and the Impact of Event Scale-Revised (IES-R-J); a measure of posttraumatic distress. Result Thirty-eight (41%) of 94 participants had experienced violence during the previous 12 months and 49 (53%) over their entire career. The most frequent violence was verbal abuse. Career length as a PVN and number of visits per month were significantly positively associated with verbal abuse during the previous 12 months. The IES-R-J scores indicated 28 of the 34 participants who completed the questionnaire exhibited psychological distress for the most traumatic violence during their career and two had a potentially high risk of posttraumatic stress disorder. Discussion and Implications Policies and strategies aimed at reducing violence in PVN settings should be developed according to characteristics of the violence, as well as the characteristics and work situation of PVNs. Furthermore, the provision of support and a safe workplace environment would be important for PVNs with residual psychological distress.

Workplace Violence Toward Mental Healthcare Workers Employed in Psychiatric Wards

Background

Workplace violence (WPV) against healthcare workers (HCWs) employed in psychiatric inpatient wards is a serious occupational issue that involves both staff and patients; the consequences of WPV may include increased service costs and lower standards of care. The purpose of this review was to evaluate which topics have been focused on in the literature and which are new in approaching the concern of patient violence against HCWs employed in psychiatric inpatient wards, in the past 20 years.

Methods

We searched for publications in PubMed and Web of Science using selected keywords. Each article was reviewed and categorized into one or more of the following four categories based on its subject matter: risk assessment, risk management, occurrence rates, and physical/nonphysical consequences.

Results

Our search resulted in a total of 64 publications that matched our inclusion criteria. The topics discussed, in order of frequency (from highest to lowest), were as follows: “risk assessment,” “risk management,” “occurrence rates,” and “physical/nonphysical consequences.” Schizophrenia, young age, alcohol use, drug misuse, a history of violence, and hostile-dominant interpersonal styles were found to be the predictors of patients’ violence.

Conclusion

Risk assessment of violence by patients appeared the way to effectively minimize the occurrence of WPV and, consequently, to better protect mental HCWs. We found paucity of data regarding psychologic sequelae of WPV. According to these findings, we suggest the need to better investigate the psychologic consequences of WPV, with the aim of checking the effective interventions to assist HCW victims of violence and to prevent psychologic illness.
