The development of an observer-scale for measuring social dysfunction and aggression

Systematic Aggression Registration in Forensic Psychiatric Care: A Qualitative Study on Preconditions for Successful Implementation

Available research emphasizes the importance of getting a systematic overview of inpatient aggression in forensic psychiatric care. However, the same research does not focus on how systematic aggression registration should be introduced in clinical practice. To facilitate the use of systematic aggression registration instruments, it is very relevant to gain insight into the perspective of staff members on the introduction of these instruments in daily clinical practice. Additionally, preconditions for achieving a successful implementation can be considered. Therefore, this study aims to gain insight into the perspective of the staff members on the implementation of a systematic aggression registration instrument-that is, the MOAS-in a forensic psychiatric unit. Interviews (n = 8) and a focus group with staff members were carried out. Three main themes: (1) creating the most appropriate context for introduction, (2) choice for the MOAS as relevant instrument, and (3) perpetuating the use of the MOAS in clinical practice are scrutinized. The mentioned preconditions can be used as guidelines when implementing systematic aggression registration in clinical practice. We hope that this paper can inspire other forensic psychiatric facilities to introduce systematic registration of aggressive incidents.

Development and evaluation of a de-escalation training intervention in adult acute and forensic units: the EDITION systematic review and feasibility trial

Background

Containment (e.g. physical restraint and seclusion) is used frequently in mental health inpatient settings. Containment is associated with serious psychological and physical harms. De-escalation (psychosocial techniques to manage distress without containment) is recommended to manage aggression and other unsafe behaviours, for example self-harm. All National Health Service staff are trained in de-escalation but there is little to no evidence supporting training's effectiveness.

Objectives

Objectives were to: (1) qualitatively investigate de-escalation and identify barriers and facilitators to use across the range of adult acute and forensic mental health inpatient settings; (2) co-produce with relevant stakeholders an intervention to enhance de-escalation across these settings; (3) evaluate the intervention's preliminary effect on rates of conflict (e.g. violence, self-harm) and containment (e.g. seclusion and physical restraint) and understand barriers and facilitators to intervention effects.

Design

Intervention development informed by Experience-based Co-design and uncontrolled pre and post feasibility evaluation. Systematic reviews and qualitative interviews investigated contextual variation in use and effects of de-escalation. Synthesis of this evidence informed co-design of an intervention to enhance de-escalation. An uncontrolled feasibility trial of the intervention followed. Clinical outcome data were collected over 24 weeks including an 8-week pre-intervention phase, an 8-week embedding and an 8-week post-intervention phase.

Setting

Ten inpatient wards (including acute, psychiatric intensive care, low, medium and high secure forensic) in two United Kingdom mental health trusts.

Participants

In-patients, clinical staff, managers, carers/relatives and training staff in the target settings.

Interventions

Enhancing de-escalation techniques in adult acute and forensic units: Development and evaluation of an evidence-based training intervention (EDITION) interventions included de-escalation training, two novel models of reflective practice, post-incident debriefing and feedback on clinical practice, collaborative prescribing and ward rounds, practice changes around admission, shift handovers and the social and physical environment, and sensory modulation and support planning to reduce patient distress.

Main outcome measures

Outcomes measured related to feasibility (recruitment and retention, completion of outcome measures), training outcomes and clinical and safety outcomes. Conflict and containment rates were measured via the Patient-Staff Conflict Checklist. Clinical outcomes were measured using the Attitudes to Containment Measures Questionnaire, Attitudes to Personality Disorder Questionnaire, Violence Prevention Climate Scale, Capabilities, Opportunities, and Motivation Scale, Coercion Experience Scale and Perceived Expressed Emotion in Staff Scale.

Results

Completion rates of the proposed primary outcome were very good at 68% overall (excluding remote data collection), which increased to 76% (excluding remote data collection) in the post-intervention period. Secondary outcomes had high completion rates for both staff and patient respondents. Regression analyses indicated that reductions in conflict and containment were both predicted by study phase (pre, embedding, post intervention). There were no adverse events or serious adverse events related to the intervention.

Conclusions

Intervention and data-collection procedures were feasible, and there was a signal of an effect on the proposed primary outcome.

Limitations

Uncontrolled design and self-selecting sample.

Future work

Definitive trial determining intervention effects.

Trial registration

This trial is registered as ISRCTN12826685 (closed to recruitment).

Context

Conflict (a term used to describe a range of potentially unsafe events including violence, self-harm, rule-breaking, medication refusal, illicit drug and alcohol use and absconding) in mental health settings causes serious physical and psychological harm. Containment interventions which are intended to minimise harm from violence (and other conflict behaviours) such as restraint, seclusion and rapid tranquilisation can result in serious injuries to patients and, occasionally, death. Involvement in physical restraint is the most common cause of serious physical injury to National Health Service mental health staff in the United Kingdom. Violence to staff results in substantial costs to the health service in sickness and litigation payments. Containment interventions are also expensive (e.g. physical restraint costs mental health services £6.1 million and enhanced observations £88 million per annum). Despite these harms, recent findings indicate containment interventions such as seclusion and physical restraint continue to be used frequently in mental health settings. Clinical trials have demonstrated that interventions can reduce containment without increasing violence and other conflict behaviours (e.g. verbal aggression, self-harm). Substantial cost-savings result from reducing containment use. De-escalation, as an intervention to manage aggression and potential violence without restrictive practices, is a core intervention. 'De-escalation' is a collective term for a range of psychosocial techniques designed to reduce distress and anger without the need to use 'containment' interventions (measures to prevent harm through restricting a person's ability to act independently, such as physical restraint and seclusion). Evidence indicates that de-escalation involves ensuring conditions for safe intervention and effective communication are established, clarifying and attempting to resolve the patient's concern, conveyance of respect and empathy and regulating unhelpful emotions such as anxiety and anger. Despite featuring prominently in clinical guidelines and training policy domestically and internationally and being a component of mandatory National Health Service training, there is no evidence-based model on which to base training. A systematic review of de-escalation training effectiveness and acceptability conducted in 2015 concluded: (1) no model of training has demonstrated effectiveness in a sufficiently rigorous evaluation, (2) the theoretical underpinning of evaluated models was often unclear and (3) there has been inadequate investigation of the characteristics of training likely to enhance acceptability and uptake. Despite all National Health Service staff being trained in de-escalation there have been no high-quality trials evaluating the effectiveness and cost-effectiveness of training. Feasibility studies are needed to establish whether it is possible to conduct a definitive trial that can determine the clinical, safety and cost-effectiveness of this intervention.

The impact of childhood maltreatment on aggression, criminal risk factors, and treatment trajectories in forensic psychiatric patients

Introduction

Children's development into healthy well-functioning adults can be negatively affected by adversity. Adverse childhood experiences (ACEs) have been shown to lead to a variety of poor life outcomes, ranging from mental health problems (e.g., anxiety or suicidality) through problematic health behaviors to serious physical diseases and even early death. ACEs can also make people more prone to aggressive behavior, criminality, and recidivism. In this study, we investigated the association between ACEs, specifically childhood maltreatment (CM), and forensically relevant factors; aggression, criminal risk factors, and treatment trajectories, as little is known about these associations in forensic psychiatric patients.

Methods

The study includes data derived from two studies in The Netherlands, of which the first study enrolled 128 patients residing in a Forensic Psychiatric Center (FPC) and the second study included 468 patients who were released unconditionally from FPCs between 2009 and 2013. We expected that more CM would be correlated with higher levels of aggression, higher clinical risk factor scores, and less decrease in clinical risk factor scores over time. To investigate this, we applied correlational analyses and linear growth curve modeling on risk assessment scores and self-report as well as staff report questionnaires on CM and aggression.

Results

Consistent with our first hypothesis, patients with higher CM scores also had higher aggression and risk assessment scores. The effect sizes were small to medium (0.12 to 0.34). Unexpectedly, CM did not influence the course of these treatment trajectories, however, we found that patients with histories of CM had a significantly longer length of stay in a forensic facility than patients without CM (respectively, 10.8 years and 9.3 years on average).

Discussion

This study underlines the importance of carefully examining the history of ACEs and CM in forensic psychiatric patients and considering this in forensic risk assessment and risk guided treatment. More research is needed to draw conclusions about whether and how histories of ACEs should be considered and targeted during treatment trajectories.

Virtual reality aggression prevention treatment in a Dutch prison-based population: a pilot study

Background

Treating violent behavior in prisons comes with challenges, such as the inability to practice safely with triggering situations and motivational issues. A solution may be the use of Virtual Reality (VR). With VR, specific conditions or needs can be tailored for individual practice, it can enhance motivation and VR has proven to be a safe and effective tool in mental health treatment.

Objective

A pilot study was conducted to test the acceptability, feasibility, and preliminary effects of VR Aggression Prevention Treatment (VRAPT) in a prison-based population.

Methods

In total 17 detainees with aggressive behavior were included in this single-group pilot study. Acceptability and feasibility were assessed using qualitative measures for participants and therapists. Preliminary treatment effects were measured with self-report and observational measures on aggression, anger, emotion regulation, and impulsiveness.

Results

Participants and therapists were predominantly positive about VRAPT. Participants rated the sessions with an average satisfaction score of 9.2 out of 10 (SD = 0.3). Qualitative data showed that participants reported having learned to respond more adequately to aggressive behavior and gained insights into their own and others' triggers and tension. The combination of VR and theory was experienced as a strength of the treatment, as well as the ability to trigger aggression in VR which provided insights into aggression. However, the theoretical framework was found to be too complex, and more aggressive and personal scenarios should be incorporated into the sessions. Self-reported aggression, anger, provocation, emotion regulation, and observed verbal aggression decreased and seemed to stabilize after the treatment ended, with small to medium effect sizes.

Conclusion

VRAPT proved feasible and acceptable for most participants and therapists. An adapted treatment protocol called Virtual Reality Treatment for Aggression Control (VR-TrAC), will be used in a future RCT to investigate the effects of the treatment in a prison-based population.

Dietary supplements for aggressive behaviour in people with intellectual disabilities: A randomised controlled crossover trial

BACKGROUND

Aggressive incidents are common in people with intellectual disabilities. Therefore, we aimed to assess whether supplementation of multivitamins, minerals, and omega-3 fatty acids (FA) reduces aggressive incidents.

METHODS

We conducted a randomised, triple blind, placebo controlled, single crossover intervention trial. People with intellectual disabilities or borderline intellectual functioning, between 12 and 40 years of age, and showing aggressive behaviour were included. Participants received either a daily dose of dietary supplements, or placebo. Primary outcome was the number of aggressive incidents, measured using the Modified Overt Aggression Scale (MOAS).

RESULTS

there were 113 participants (placebo, n = 56), of whom 24 (placebo, n = 10) participated in the crossover phase of the trial. All 137 trajectories were included in the analyses. There was no significant difference in mean number of aggressive incidents per day between those assigned to supplements and those who received placebo (rate ratio = 0.93: 95% Confidence Interval [CI] = 0.59-1.45).

CONCLUSION

In this pragmatic trial, we did not find significant differences in the outcomes between the supplement and placebo arms. The COVID-19 pandemic started midway through our trial, this may have affected the results.

The effectiveness of intensive home treatment as a substitute for hospital admission in acute psychiatric crisis resolution in the Netherlands: a two-centre Zelen double-consent randomised controlled trial

BACKGROUND

Although de-institutionalisation has been underway for decades, admission to hospital followed by low-intensity outpatient care remains the usual treatment for patients with an acute psychiatric crisis. Intensive home treatment has been developed for patients in a severe psychiatric crisis as an alternative to inpatient care. This study aimed to evaluate the potential of intensive home treatment to reduce bed-days and its clinical effectiveness compared with treatment as usual.

METHODS

We did a two-armed, two-centre, open-label, Zelen, double-consent, pragmatic randomised controlled trial. Patients aged 18-65 years were recruited at the psychiatric emergency service and psychiatric emergency wards of the two major mental health institutions (Arkin and GGZ inGeest) in Amsterdam, the Netherlands. Patients diagnosed with at least one DSM-IV-TR or DSM-5 disorder and in a psychiatric crisis and for whom psychiatrists had indicated or completed a clinical admission could be included. Trained psychiatric emergency service and hospital professionals did the automated web-based pre-randomisation procedure upon first contact with the patient. A seeded pseudo-random number generator allocated patients (2:1) to intensive home treatment or treatment as usual. Informed consent was obtained after randomisation as soon as the patient was mentally capable within 14 days. Due to the nature of this study, patients and professionals were not masked to treatment. Intensive home treatment was tailored to the nature of the crisis and goals of patients and relatives, and developed in collaboration with them and a multidisciplinary professional team. All main analyses were intention-to-treat, and the primary outcome was the total number of admission days 12 months after randomisation. To investigate the effect of treatment conditions on the outcome measures, linear mixed modelling analyses using restricted maximum likelihood estimation were done. This trial was prospectively registered with Trialregister.nl, NL-6020 (NTR-6151).

FINDINGS

Between Nov 15, 2016, and Oct 15, 2018, 246 patients were included in the study (183 patients with intensive home treatment vs 63 patients with treatment as usual). 135 women (55%) and 111 men (45%) were included, with a mean age of 41·01 years (range 18-65; SD 12·68). 114 participants (46%) were born in the Netherlands and 85 (35%) elsewhere (missing data on 47 [19%] participants). Ethnicity data were not available. After 12 months, the mean number of admission days in the intensive home treatment condition was 42·47 (SD 53·92) versus 67·02 (SD 79·03) for treatment as usual, a reduction of 24·55 days (SD 10·73) or 36·6% (p=0·033). 26 adverse events were registered, 23 (89%) of which were suicide attempts. The number of patients with a reported adverse event did not differ significantly between the groups (15 [8%] in the intensive home treatment group vs five [8%] in the treatment as usual group; p=0·950). Five patients died by suicide (three [2%] in the intensive home treatment group vs two [3%] in the treatment as usual group; p=0·610). No treatment-related deaths occurred.

INTERPRETATION

Intensive home treatment is a safe and effective partial substitute for conventional psychiatric crisis care that led to a reduction in admission days, causing patients to stay longer in their social environment, with similar clinical effects, patient satisfaction and adverse events.

Acceptance and potential clinical added value of biocueing in forensic psychiatric patients with autism spectrum disorder and/or intellectual disability

Autism spectrum disorder (ASD) and intellectual disability (ID) are prevalent in forensic psychiatric samples. People with ASD and/or ID often experience difficulties in emotion processing which can lead to aggressive or self-harming behavior. The use of biocueing (using wearable technology to constantly monitor and provide feedback on bodily changes) shows promise for improving emotion processing and, thus, potentially reducing aggressive behavior in this population. Both qualitative and quantitative methods were used to examine the feasibility and acceptance of Sense-IT, a biocueing application, in a sample of forensic psychiatric patients with ASD and/or ID and their forensic psychiatric nurses. To our knowledge, the current study is the first to examine first-person experiences with biocueing in forensic psychiatric patients with ASD and/or ID. Results show that, in general, participants experienced the biocueing application as positive and are willing to use biocueing. This is an important finding since forensic patients are often unmotivated to engage with therapeutic techniques. An exploration of trends in aggression and self-harm prior to and during the use of biocueing showed no significant changes. Future research should focus on the way biocueing can be implemented in clinical practice.

Instruments for Measuring Violence on Acute Inpatient Psychiatric Units: Review and Recommendations

OBJECTIVE

Violence by patients against inpatient psychiatric unit staff is common, causing considerable suffering. Despite the Joint Commission's 2018 requirement for behavioral health organizations to use standardized instruments, no identified gold standard measures of violence and aggression exist. Therefore, accurate data are lacking on the frequency of patient-to-staff violence to guide development of safer institutional clinical policies or to assess the impact of targeted interventions to reduce violence. To inform recommendations for developing standardized scales, the authors reviewed the scoring instruments most commonly used to measure violence in recent studies.

METHODS

A comprehensive literature search for violence measurement instruments in articles published in English from June 2008 to June 2018 was performed. Review criteria included use of instruments measuring patient-to-staff violence or aggression in acute, nonforensic, nongeriatric populations. Exclusion criteria included child or adolescent populations, staff-to-staff violence, and staff- or visitor-to-patient violence.

RESULTS

Overall, 74 studies were identified, of which 74% used structured instruments to measure aggression and violence on inpatient psychiatric units during the past 10 years. The instruments were primarily variants of the Observed Aggression Scale (OAS); 26% of the studies used unstructured clinical notes and researcher questionnaires. Major obstacles to implementing measurement instruments included time and workflow constraints and difficulties with use.

CONCLUSIONS

In the past 10 years, OAS variants with evidence of validity and reliability that define aggression and violence have been consistently used. The authors propose that adapting the Modified OAS to collect real-time clinical data could help overcome barriers to implementing standardized instruments to quantify violence against psychiatric staff.

Effects of multivitamin, mineral and n-3 polyunsaturated fatty acid supplementation on aggression among long-stay psychiatric in-patients: randomised clinical trial

BACKGROUND

Aggression and violent incidents are a major concern in psychiatric in-patient care. Nutritional supplementation has been found to reduce aggressive incidents and rule violations in forensic populations and children with behavioural problems.

AIMS

To assess whether multivitamin, mineral and n-3 polyunsaturated fatty acid supplementation would reduce the number of aggressive incidents among long-stay psychiatric in-patients.

METHOD

The trial was a pragmatic, multicentre, randomised, double-blind placebo-controlled study. Data were collected from 25 July 2016 to 29 October 2019, at eight local sites for mental healthcare in The Netherlands and Belgium. Participants were randomised (1:1) to receive 6-month treatment with either three supplements containing multivitamins, minerals and n-3 polyunsaturated fatty acid, or placebo. The primary outcome was the number of aggressive incidents, determined by the Staff Observation Aggression Scale - Revised (SOAS-R). Secondary outcomes were patient quality of life, affective symptoms and adverse events.

RESULTS

In total, 176 participants were randomised (supplements, n = 87; placebo, n = 89). Participants were on average 49.3 years old (s.d. 14.5) and 64.2% were male. Most patients had a psychotic disorder (60.8%). The primary outcome of SOAS-R incidents was similar in supplement (1.03 incidents per month, 95% CI 0.74-1.37) and placebo groups (0.90 incidents per month, 95% CI 0.65-1.19), with a rate ratio of 1.08 (95% CI 0.67-1.74, P = 0.75). Differential effects were not found in sensitivity analyses on the SOAS-R or on secondary outcomes.

CONCLUSIONS

Six months of nutritional supplementation did not reduce aggressive incidents among long-stay psychiatric in-patients.

Testing the Effects of a Virtual Reality Game for Aggressive Impulse Management: A Preliminary Randomized Controlled Trial among Forensic Psychiatric Outpatients

Prior laboratory experiments among healthy samples found that training avoidance movements to angry faces may lower anger and aggression, especially people high in trait anger. To enrich this training and make it more suitable for clinical applications, the present researchers developed it into a Virtual Reality Game for Aggressive Impulse Management (VR-GAIME). The current study examined the effects of this training in a randomized controlled trial among forensic psychiatric outpatients with aggression regulation problems (N = 30). In addition to the aggression replacement training, patients played either the VR-GAIME or a control game. Aggressive behavior was measured pre-, half-way, and post-treatment via self-report and clinicians ratings. No difference was found between the VR-GAIME and the control game. However, the participants reported gaining more insight into their own behavior and that of others. Future VR intervention tools in clinical settings may capitalize more on their benefits for self-reflection within interpersonal settings.

Mapping aggressive behavior of forensic psychiatric inpatients with self-report and structured staff-monitoring

Structured assessment of aggressive behavior in forensic psychiatry is needed. This study investigated staff-observed and self-reported measures to map prevalence and characteristics of aggressive behavior in forensic inpatients and aimed to identify early signs of aggressive outbursts. In this longitudinal study, 120 forensic psychiatric inpatients with a history of aggression were included. Staff monitored aggressive behavior for 30 weeks using the Social Dysfunction and Aggression Scale (SDAS). Patients completed baseline self-report measures on aggression, anger, and impulsivity. Staff monitoring showed that most inpatients displayed moderate (86%) or severe (65%) aggressive behavior at least once, and 37.5% showed physical aggression. Inpatients with a least one physical aggression incident differed from others in self-reported anger, (reactive) aggression, non-planning impulsivity, and sociodemographic and clinical characteristics (e.g., higher prevalence of cluster B personality disorders, and lower intelligence). Two-thirds of the physical aggression incidents were preceded by observations of increased non-physical aggression (SDAS). In forensic psychiatric inpatients with a history of aggression, more than a third of the patients demonstrated at least one occasion of physical aggression during 30 weeks of observation.

Pharmacological interventions to reduce violence in patients with schizophrenia in forensic psychiatry

BACKGROUND

The purpose was to systematically investigate which pharmacological strategies are effective to reduce the risk of violence among patients with Schizophrenia Spectrum Disorders (SSD) in forensic settings.

METHODS

For this systematic review six electronic data bases were searched. Two researchers independently screened the 6,003 abstracts resulting in 143 potential papers. These were then analyzed in detail by two independent researchers. Of these, 133 were excluded for various reasons leaving 10 articles in the present review.

RESULTS

Of the 10 articles included, five were merely observational, and three were pre-post studies without controls. One study applied a matched case-control design and one was a non-randomized controlled trial. Clozapine was investigated most frequently, followed by olanzapine and risperidone. Often, outcome measures were specific to the study and sample sizes were small. Frequently, relevant methodological information was missing. Due to heterogeneous study designs and outcomes meta-analytic methods could not be applied.

CONCLUSION

Due to substantial methodological limitations it is difficult to draw any firm conclusions about the most effective pharmacological strategies to reduce the risk of violence in patents with SSD in forensic psychiatry settings. Studies applying more rigorous methods regarding case-definition, outcome measures, sample sizes, and study designs are urgently needed.

Monitoring risk assessment on an acute psychiatric ward: Effects on aggression, seclusion and nurse behaviour

Evidence of risk assessment procedures is scarce and inconclusive. The aim of this study is to evaluate the effects of risk assessment on aggression and the use of coercive interventions in an acute psychiatric admission setting. In addition, we evaluated nurse behaviour before and after the use of risk assessment. To take the fluctuations with regard to aggression and coercive interventions into account, we allowed 26 weeks for baseline measurements, followed by a 26 weeks steady-state period after the implementation of the risk assessment instrument. Contrary to expectations, no positive effects of risk assessment were found on aggression or on coercive interventions. Time spent in seclusion increased significantly with more than 10 hours on average after implementation. Furthermore, there were only negative effects on nurse behaviour and experiences. Among other things, they felt more stressed, spent more time on administration tasks and spent less time with patients after the implementation. In conclusion, there is insufficient evidence to use structured short-term risk assessment to reduce aggression or coercive interventions.

Virtual Reality Aggression Prevention Therapy (VRAPT) versus Waiting List Control for Forensic Psychiatric Inpatients: A Multicenter Randomized Controlled Trial

Many forensic psychiatric inpatients have difficulties regulating aggressive behavior. Evidence of effective aggression treatments is limited. We designed and investigated the effectiveness of a transdiagnostic application of a virtual reality aggression prevention training (VRAPT). In this randomized controlled trial at four Dutch forensic psychiatric centers, 128 inpatients with aggressive behavior were randomly assigned to VRAPT (N = 64) or waiting list control group (N = 64). VRAPT consisted of 16 one-hour individual treatment sessions twice a week. Assessments were done at baseline, post-treatment and at 3-month follow-up. Primary outcome measures were aggressive behavior observed by staff and self-reported aggressive behavior. Analysis was by intention to treat. This trial was registered in the Dutch Trial Register (NTR, TC = 6340). Participants were included between 1 March 2017, and 31 December 2018. Compared to waiting list, VRAPT did not significantly decrease in self-reported or observed aggressive behavior (primary outcomes). Hostility, anger control, and non-planning impulsiveness improved significantly in the VRAPT group compared to the control group at post-treatment. Improvements were not maintained at 3-month follow-up. Results suggest that VRAPT does not decrease aggressive behavior in forensic inpatients. However, there are indications that VRAPT temporarily influences anger control skills, impulsivity and hostility.

Organisational interventions for preventing and minimising aggression directed towards healthcare workers by patients and patient advocates

BACKGROUND

Workplace aggression is becoming increasingly prevalent in health care, with serious consequences for both individuals and organisations. Research and development of organisational interventions to prevent and minimise workplace aggression has also increased. However, it is not known if interventions prevent or reduce occupational violence directed towards healthcare workers.

OBJECTIVES

To assess the effectiveness of organisational interventions that aim to prevent and minimise workplace aggression directed towards healthcare workers by patients and patient advocates.

SEARCH METHODS

We searched the following electronic databases from inception to 25 May 2019: Cochrane Central Register of Controlled Trials (CENTRAL) (Wiley Online Library); MEDLINE (PubMed); CINAHL (EBSCO); Embase (embase.com); PsycINFO (ProQuest); NIOSHTIC (OSH-UPDATE); NIOSHTIC-2 (OSH-UPDATE); HSELINE (OSH-UPDATE); and CISDOC (OSH-UPDATE). We also searched the ClinicalTrials.gov (www.ClinicalTrials.gov) and the World Health Organization (WHO) trials portals (www.who.int/ictrp/en).

SELECTION CRITERIA

We included randomised controlled trials (RCTs) or controlled before-and-after studies (CBAs) of any organisational intervention to prevent and minimise verbal or physical aggression directed towards healthcare workers and their peers in their workplace by patients or their advocates. The primary outcome measure was episodes of aggression resulting in no harm, psychological, or physical harm.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods for data collection and analysis. This included independent data extraction and 'Risk of bias' assessment by at least two review authors per included study. We used the Haddon Matrix to categorise interventions aimed at the victim, the vector or the environment of the aggression and whether the intervention was applied before, during or after the event of aggression. We used the random-effects model for the meta-analysis and GRADE to assess the quality of the evidence.

MAIN RESULTS

We included seven studies. Four studies were conducted in nursing home settings, two studies were conducted in psychiatric wards and one study was conducted in an emergency department. Interventions in two studies focused on prevention of aggression by the vector in the pre-event phase, being 398 nursing home residents and 597 psychiatric patients. The humour therapy in one study in a nursing home setting did not have clear evidence of a reduction of overall aggression (mean difference (MD) 0.17, 95% confidence interval (CI) 0.00 to 0.34; very low-quality evidence). A short-term risk assessment in the other study showed a decreased incidence of aggression (risk ratio (RR) 0.36, 95% CI 0.16 to 0.78; very low-quality evidence) compared to practice as usual. Two studies compared interventions to minimise aggression by the vector in the event phase to practice as usual. In both studies the event was aggression during bathing of nursing home patients. In one study, involving 18 residents, music was played during the bathing period and in the other study, involving 69 residents, either a personalised shower or a towel bath was used. The studies provided low-quality evidence that the interventions may result in a medium-sized reduction of overall aggression (standardised mean difference (SMD -0.49, 95% CI -0.93 to -0.05; 2 studies), and physical aggression (SMD -0.85, 95% CI -1.46 to -0.24; 1 study; very low-quality evidence), but not in verbal aggression (SMD -0.31, 95% CI; -0.89 to 0.27; 1 study; very low-quality evidence). One intervention focused on the vector, the pre-event phase and the event phase. The study compared a two-year culture change programme in a nursing home to practice as usual and involved 101 residents. This study provided very low-quality evidence that the intervention may result in a medium-sized reduction of physical aggression (MD 0.51, 95% CI 0.11 to 0.91), but there was no clear evidence that it reduced verbal aggression (MD 0.76, 95% CI -0.02 to 1.54). Two studies evaluated a multicomponent intervention that focused on the vector (psychiatry patients and emergency department patients), the victim (nursing staff), and the environment during the pre-event and the event phase. The studies included 564 psychiatric staff and 209 emergency department staff. Both studies involved a comprehensive package of actions aimed at preventing violence, managing violence and environmental changes. There was no clear evidence that the psychiatry intervention may result in a reduction of overall aggression (odds ratio (OR) 0.85, 95% CI 0.63 to 1.15; low-quality evidence), compared to the control condition. The emergency department study did not result in a reduction of aggression (MD = 0) but provided insufficient data to test this.

AUTHORS' CONCLUSIONS

We found very low to low-quality evidence that interventions focused on the vector during the pre-event phase, the event phase or both, may result in a reduction of overall aggression, compared to practice as usual, and we found inconsistent low-quality evidence for multi-component interventions. None of the interventions included the post-event stage. To improve the evidence base, we need more RCT studies, that include the workers as participants and that collect information on the impact of violence on the worker in a range of healthcare settings, but especially in emergency care settings. Consensus on standardised outcomes is urgently needed.

Clinical target syndromes in psychiatry: latent structure analysis versus factor analysis

The algorithms for the demonstration of shared phenomenology of psychiatric syndromes in DSM-III are resistant to quantification. In contrast, the rating scale approach quantifies clinical target syndromes in psychiatry. The two most useful statistical models for quantifying shared phenomenology by symptom rating scales have been reviewed; namely factor analysis and latent structure analysis. Results have shown that factor analysis has demonstrated dimensions of dementia, delirium, schizophrenia, mania, outward aggression, depression and anxiety. Latent structure analysis has confirmed that the items of brief rating scales (such as the Melancholia Scale) are additively related implying that their total scores are sufficient statistics for the measurement of these factors or dimensions. Latent structure analysis should be considered as a psychometric “glasnost” compared to algorithm-resistant logic of quantification in DSM-III.

Are Owls and Larks Different When it Comes to Aggression? Genetics, Neurobiology, and Behavior

This review focuses on the contribution of circadian rhythms to aggression with a multifaceted approach incorporating genetics, neural networks, and behavior. We explore the hypothesis that chronic circadian misalignment is contributing to increased aggression. Genes involved in both circadian rhythms and aggression are discussed as a possible mechanism for increased aggression that might be elicited by circadian misalignment. We then discuss the neural networks underlying aggression and how dysregulation in the interaction of these networks evoked by circadian rhythm misalignment could contribute to aggression. The last section of this review will present recent human correlational data demonstrating the association between chronotype and/or circadian misalignment with aggression. With circadian rhythms and aggression being a burgeoning area of study, we hope that this review initiates more interest in this promising and topical area.

Effectiveness of integrated psychological therapy on cognitive function among Lebanese patients with schizophrenia: a pilot study

Background: The integrated term emphasises the need for cognitive therapy to always be embedded into an extended treatment concept adapted to cognitive resources and deficits and to patient rehabilitation. One of the first approaches is integrated psychological therapy (IPT).Aim: To assess the effect of the IPT Programme compared to the Treatment as Usual (TaU) in terms of cognitive performance and social skills among a group of schizophrenic patients.Methods: This randomised controlled study enrolled 20 patients in each group. Patients attended 60-min sessions, 3 days/week.Results: When considering the TaU group, the bivariate results showed that significantly higher means of attention scores, lower means in social dysfunction and aggression, social adaptation scores were found after IPT compared to before. The effect size for all tests was found to be weak. When considering the IPT group, significantly higher means attention score, lower means cognitive disorders, social dysfunction, aggression and social adaptation scores were found after IPT compared to before. The effect size for all tests was found to be high.Conclusion: The therapeutic combination of the IPT programme with medical treatment has shown additional beneficial effects on the schizophrenic patients' treatment, enabling them, as far as possible, to reintegrate into the community.KEY POINTSIn cases, a significantly higher GZ-F and KL scores and a lower SDAS-9 and SDAS-6 scores were found post-IPT respectively.In controls, a significant increase in the GZ-F and KL subscales and a decrease in all other scales was found post-IPT respectively.This therapeutic combination of the integrative programme with medical treatment has shown additive beneficial effects in patients with schizophreniaThe treatment approach would allow them, as far as possible, to reintegrate within the community.

Associations of multiple trauma types and MAOA with severe aggressive behavior and MAOA effects on training outcome

Previous research showed that the disposition to react with disproportionate aggression in adults is influenced by an interaction between a variant in the X-chromosomal monoamine oxidase A gene (MAOA) and early traumatic events. Such studies have often focused on a single type of trauma, whereas we know that experiencing multiple trauma types is associated with more detrimental consequences. The differential susceptibility hypothesis suggests that individuals who are most susceptible to adversity, are also most likely to benefit from supportive experiences in childhood. Differences in susceptibility are thought to be partly genetically driven. In the present study we explored whether a genotype of MAOA linked to lower expression of the gene (MAOA-L) modified the effect of multiple types of trauma on aggression and/or altered responsiveness to treatment among adults with severe aggression. Forensic psychiatric outpatients (FPOs) (N=150) receiving treatment for aggression regulation problems were recruited. Traumatic events and aggression were measured using self-report. FPOs with multiple trauma types and those with the MAOA-L allele reported more severe levels of aggression. No interaction effects between MAOA genotype and trauma emerged. There were no differences in response to the intervention between FPOs with and without the MAOA-L variant, whereas FPOs with a single type of trauma showed the slowest reduction of aggression. FPOs with multiple types of trauma reported the highest levels of aggression over the course of treatment. Future research is needed to elucidate this association in further detail. The current study emphasized the importance of early recognition of early traumatic events.

Long-Term Effects of a Behavioural Management Technique for Nurses on Aggressive Behaviour in Brain-Injured Patients

OBJECTIVE

The ABC method (Antecedent events, target Behaviours, Consequent events) is a behavioural management technique developed for nurses. The objective of the present study was to examine the long-term effects of the ABC method on aggressive behaviour in 40 patients with acquired brain injury.

METHOD

Four aggression outcome measures and a questionnaire about the implementation of the ABC method were filled out by the nursing staff in this longitudinal intervention study.

RESULTS

Contrary to expectations, a significant increase of aggression was found on two aggression measures. A possible explanation may be that the ABC method increased awareness of aggression in the nursing staff. Results of the implementation questionnaire indicated that the ABC method was not part of usual care at the long-term follow-up.

CONCLUSIONS

It seems that the quality of the implementation process was insufficient to find an effect of the ABC method on aggression. Suggestions for improving the implementation process are made in this paper.

Testing the Effects of a Virtual Reality Game for Aggressive Impulse Management (VR-GAIME): Study Protocol

Background: Prior laboratory findings indicate that training avoidance movements to angry faces may lower anger and aggression among healthy participants, especially those high in trait anger. To enrich this training and make it more suitable for clinical applications, it has been developed into a Virtual Reality Game for Aggressive Impulse Management (VR-GAIME). Methods: The proposed study will examine the effects of this training in a randomized controlled trial among forensic psychiatric outpatients with aggression regulation problems (N = 60). In addition to the aggression replacement training, participants will play either the VR-GAIME or a control game. Anger will be assessed using self-report. Aggressive impulses will be measured via self-report, a validated laboratory paradigm, and rated by clinicians. Discussion: The authors hypothesize that the combination of the VR-GAIME and regular aggression treatment will be more successful in reducing aggressive behavior. One of the strengths of the proposed study is that it is the first to examine the effects of a motivational intervention in a clinical sample characterized by problems in regulating anger and aggression. Another strength of the proposed study is that the VR-GAIME will be implemented as a multi-session intervention. Additionally, the VR-GAIME applies, for the first time, serious gaming and virtual reality on an avoidance motivation intervention. If positive results are found, the VR-GAIME may be systematically deployed in forensic psychiatric settings. Trial registration: The trial is registered with The Netherlands National Trial Register, number: NTR6986.

Valproate preparations for agitation in dementia

BACKGROUND

Agitation has been reported in up to 90% of people with dementia. Agitation in people with dementia worsens carer burden, increases the risk of injury, and adds to the need for institutionalisation. Valproate preparations have been used in an attempt to control agitation in dementia, but their safety and efficacy have been questioned.

OBJECTIVES

To determine the efficacy and adverse effects of valproate preparations used to treat agitation in people with dementia, including the impact on carers.

SEARCH METHODS

We searched ALOIS - the Cochrane Dementia and Cognitive Improvement Group's Specialized Register on 7 December 2017 using the terms: valproic OR valproate OR divalproex. ALOIS contains records from all major health care databases (the Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, LILACS) as well as from many trials databases and grey literature sources.

SELECTION CRITERIA

Randomised, placebo-controlled trials that assessed valproate preparations for agitation in people with dementia.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the retrieved studies against the inclusion criteria and extracted data and assessed methodological quality of the included studies. If necessary, we contacted trial authors to ask for additional data, including relevant subscales, or for other missing information. We pooled data in meta-analyses where possible. This is an update of a Cochrane Review last published in 2009. We found no new studies for inclusion.

MAIN RESULTS

The review included five studies with 430 participants. Studies varied in the preparations of valproate, mean doses (480 mg/day to 1000 mg/day), duration of treatment (three weeks to six weeks), and outcome measures used. The studies were generally well conducted although some methodological information was missing and one study was at high risk of attrition bias.The quality of evidence related to our primary efficacy outcome of agitation varied from moderate to very low. We found moderate-quality evidence from two studies that measured behaviour with the total Brief Psychiatric Rating Scale (BPRS) score (range 0 to 108) and with the BPRS agitation factor (range 0 to 18). They found that there was probably little or no effect of valproate treatment over six weeks (total BPRS: mean difference (MD) 0.23, 95% confidence interval (CI) -2.14 to 2.59; 202 participants, 2 studies; BPRS agitation factor: MD -0.67, 95% CI -1.49 to 0.15; 202 participants, 2 studies). Very low-quality evidence from three studies which measured agitation with the Cohen-Mansfield Agitation Index (CMAI) were consistent with a lack of effect of valproate treatment on agitation. There was variable quality evidence on other behaviour outcomes reported in single studies of no difference between groups or a benefit for the placebo group.Three studies, which measured cognitive function using the Mini-Mental State Examination (MMSE), found little or no effect of valproate over six weeks, but we were uncertain about this result because the quality of the evidence was very low. Two studies that assessed functional ability using the Physical Self-Maintenance Scale (PSMS) (range 6 to 30) found that there was probably slightly worse function in the valproate-treated group, which was of uncertain clinical importance (MD 1.19, 95% CI 0.40 to 1.98; 203 participants, 2 studies; moderate-quality evidence).Analysis of adverse effects and serious adverse events (SAE) indicated a higher incidence in valproate-treated participants. A meta-analysis of three studies showed that there may have been a higher rate of adverse effects among valproate-treated participants than among controls (odds ratio (OR) 2.02, 95% CI 1.30 to 3.14; 381 participants, 3 studies, low-quality evidence). Pooled analysis of the number of SAE for the two studies that reported such data indicated that participants treated with valproate preparations were more likely to experience SAEs (OR 4.77, 95% CI 1.00 to 22.74; 228 participants, 2 studies), but the very low quality of the data made it difficult to draw any firm conclusions regarding SAEs. Individual adverse events that were more frequent in the valproate-treated group included sedation, gastrointestinal symptoms (nausea, vomiting, and diarrhoea), and urinary tract infections.

AUTHORS' CONCLUSIONS

This updated review corroborates earlier findings that valproate preparations are probably ineffective in treating agitation in people with dementia, but are associated with a higher rate of adverse effects, and possibly of SAEs. On the basis of this evidence, valproate therapy cannot be recommended for management of agitation in dementia. Further research may not be justified, particularly in light of the increased risk of adverse effects in this often frail group of people. Research would be better focused on effective non-pharmacological interventions for this patient group, or, for those situations where medication may be needed, further investigation of how to use other medications as effectively and safely as possible.

Treatment Responsivity of Aggressive Forensic Psychiatric Outpatients

Aggression replacement training (ART) is widely used to reduce aggression. Results regarding its effectiveness, however, are inconclusive regarding adults and specific populations displaying severe aggression. The current open uncontrolled treatment study aimed at assessing the social skills and anger control modules of the ART to reduce aggression in forensic psychiatric outpatients (FPOs). Furthermore, characteristics associated with treatment outcome and dropout were examined. The results suggested that aggression changed during the ART. In addition, higher baseline levels of trait aggression were associated with greater reductions of aggression, whereas more cognitive distortions were associated with less reduction. Treatment dropouts were characterized by higher levels of psychopathic traits, proactive aggression, and more weekly substance use. As there was a considerable amount of dropout; it is important to assess risk of dropping out of treatment and, subsequently, improve treatment motivation. This might enhance treatment adherence which may lead to a more successful reduction of aggression.

Associations Between Neurocognitive Characteristics, Treatment Outcome, and Dropout Among Aggressive Forensic Psychiatric Outpatients

Aggression Replacement Training (ART) is widely used to reduce aggression and is considered to be effective although there are also inconsistent results. Studies investigating the effectiveness of ART do not focus on neurocognitive characteristics. Focusing on these aspects would result in enhanced understanding of underlying mechanisms of ART. The current open uncontrolled treatment study assessed whether neurocognitive characteristics were associated with change in aggression during the social skills and anger control modules of ART among forensic psychiatric outpatients. Furthermore, differences between treatment dropouts and completers and change in these characteristics during ART were examined. A reduction of trait aggression, cognitive distortions, and social anxiety was observed. Neurocognitive characteristics were not associated with change in aggression, could not distinguish treatment completers from dropouts, and did not change after ART. It is suggested that new paradigms should be developed which take into account the social context in which these impairments appear.

Dose reduction of high-dose first-generation antipsychotics or switch to ziprasidone in long-stay patients with schizophrenia: A 1-year double-blind randomized clinical trial

Long-stay patients with severe schizophrenia are frequently treated with high doses of first-generation antipsychotics (FGA). Dose reduction or switching to ziprasidone may reduce the severity of negative symptoms and side effects. We investigated in a randomized double-blind trial whether a dose-reduction strategy to achieve an adequate dose of a FGA (5 mg/day haloperidol equivalents, n = 24) or switching to ziprasidone (160 mg/day, n = 24) in treatment resistant patients would decrease negative symptoms after 1 year of treatment. We found that negative symptoms did not change significantly in either condition. Positive symptoms, excited symptoms, and emotional distress worsened over time with ziprasidone, resulting in a significant difference between conditions in favour of FGA dose reduction. Relapse and treatment failure, defined as a prolonged or repeated relapse, occurred more often with ziprasidone than with FGA (45.8% versus 20.8%, and 25.0% versus 16.7%, respectively). Treatment with ziprasidone was superior for extrapyramidal symptoms. Our study establishes that lowering high FGA doses to an equivalent of 5 mg/day haloperidol or switching to ziprasidone is feasible in the vast majority of patients but does not improve negative or other symptoms. Neither FGA dose reduction nor switching to ziprasidone is an adequate alternative to clozapine for long-stay patients with severe treatment resistant schizophrenia.

Effect of virtual reality aggression prevention training for forensic psychiatric patients (VRAPT): study protocol of a multi-center RCT

BACKGROUND

Many patients residing in forensic psychiatric centers have difficulties regulating their aggression in an adequate manner. Therefore, they are frequently involved in conflicts. Evidenced-based aggression therapies in forensic psychiatry are scarce, and due to the highly secured environment, it is hard to practice real-life provocations. We have developed a Virtual Reality aggression prevention training (VRAPT), providing safe virtual environments, in which patients can practice controlling their aggressive behaviors in an adequate way. The main objective of this study is to examine whether VRAPT is effective in reducing aggression among forensic psychiatric inpatients.

METHODS

Four forensic psychiatric centers in the Netherlands are participating in this study. Participants will be randomly assigned to either VRAPT or a waiting list. The two groups will be compared at several different time points: baseline (12 weeks before intervention), pre-intervention, post-intervention and at 12 weeks follow-up. After follow-up measurements are completed, participants from the waiting list will also receive VRAPT. The primary outcome is level of aggressive behavior, consisting of staff-reported and self-reported measures. Secondary outcomes are self-report questionnaires on e.g., anger, impulsivity and aggression.

DISCUSSION

To the best of our knowledge this is the first study to examine the effectiveness of a VR aggression prevention training in forensic psychiatric centers. Further details on the methodological issues are discussed in this paper.

[Forensic preventive assertive community treatment : Pilot project to prevent violent crimes in the context of psychiatric disorders]

BACKGROUND

Since 2012, a forensic preventive outpatient clinic has been established at Ansbach District Hospital to fill a gap in general psychiatric care for patients with schizophrenia or severe personality disorders and having a high risk for violent behavior. An interdisciplinary team drawing on forensic psychiatric knowledge applies instruments for forensic risk prognosis and treatment or interventions to prevent violent crimes and to protect potential victims. Admissions depend on certain criteria, e.g., increased risk potential for violent crimes against the background of schizophrenia or severe personality disorders.

OBJECTIVE

How can a forensic psychiatric preventive treatment be organized, which helps to avoid detention in a forensic commitment and is complementary to general psychiatric treatment structures? Can such a model project reach the target group?

MATERIAL AND METHOD

In forensic preventive outpatient care the treatment is based on violence prevention (e.g., psychoeducation, group training, individual treatment on violence risk co-management). Data are collected using general psychiatric and forensic instruments on, e.g., risk of violence (HCR-20), global functional level (GAF), violent behavior (SDAS-9) on a regular basis. The values with respect to these instruments on admission were compared to published key factors from population samples with general and forensic psychiatric patients.

RESULTS

A total of 146 patients between the ages of 18 and 79 years have so far been treated. About 4,000,000 EUR could be saved during the duration of the project because of preventing involuntary admission to a forensic hospital apart from preventing violent crimes. In contrast 3,000,000 EUR had to be spent for the new outpatient service.

CONCLUSION

Indications for the efficacy of a forensic preventive care for patients with schizophrenia and severe personality disorders with a risk for violence are confirmed. Therefore, an institutionalization and a statewide implementation of forensic preventive care in terms of the forensic preventive out-patient clinic are recommended.

Lack of correspondence between the reactive proactive questionnaire and the impulsive premeditated aggression scale among forensic psychiatric outpatients

The most studied bimodal classifications of aggressive behavior are the impulsive/premeditated distinction measured with the Impulsive Premeditated Aggression Scale and the reactive/proactive distinction measured with the Reactive Proactive Questionnaire. The terms of these classifications are often used interchangeably, assuming that reactive aggression is equivalent to impulsive aggression and that proactive aggressive behavior is the same as premeditated aggression. The correspondence or discrepancy between both aggression classifications/questionnaires, however, is understudied. Therefore, the current study investigated the correspondence between the RPQ and IPAS in a sample of 161 forensic psychiatric outpatients (FPOs) with severe aggressive behavior. Correlation analysis revealed a limited correspondence between the RPQ and IPAS. Cluster analyses derived three clusters from the RPQ as well as the IPAS: these clusters did not match in 60.3% of the cases. Furthermore, the notion that the RPQ measures trait aggression whereas the IPAS assesses state aggression could not be verified. The present study indicates that aggression subtypes as measured by use of the RPQ and IPAS correspond only partially and should not be used interchangeably. Furthermore, it was suggested that RPQ focuses more on actual aggressive behavior and the IPAS more on emotions and their regulation. Future research is needed to elucidate the applicability of both questionnaires in further detail.

Electroconvulsive Therapy for Agitation and Aggression in Dementia: A Systematic Review

OBJECTIVES

Many patients with dementia develop agitation or aggression in the course of their disease. In some severe cases, behavioral, environmental, and pharmacological interventions are not sufficient to alleviate these potentially life-threatening symptoms. It has been suggested that in those cases, electroconvulsive therapy (ECT) could be an option. This review summarizes the scientific literature on ECT for agitation and aggression in dementia.

METHODS

We performed a systematic review in accordance with PRISMA guidelines. A search was conducted in Ovid MEDLINE, EMBASE, and PsycINFO. Two reviewers extracted the following data from the retrieved articles: number of patients and their age, gender, diagnoses, types of problem behavior, treatments tried before ECT, specifications of the ECT treatment, use of rating scales, treatment results, follow-up data, and adverse effects.

RESULTS

The initial search yielded 264 articles, 17 of which fulfilled the inclusion criteria. Of these studies, one was a prospective cohort study, one was a case-control study, and the others were retrospective chart reviews, case series, or case reports. Clinically significant improvement was observed in the majority (88%) of the 122 patients described, often early in the treatment course. Adverse effects were most commonly mild, transient, or not reported.

CONCLUSIONS

The reviewed articles suggest that ECT could be an effective treatment for severe and treatment-refractory agitation and aggression in dementia, with few adverse consequences. Nevertheless, because of the substantial risk of selection bias, the designs of the studies reviewed, and their small number, further prospective studies are needed to substantiate these preliminary positive results.

Intensive home treatment for patients in acute psychiatric crisis situations: a multicentre randomized controlled trial

BACKGROUND

Hospitalization is a common method to intensify care for patients experiencing a psychiatric crisis. A short-term, specialised, out-patient crisis intervention by a Crisis Resolution Team (CRT) in the Netherlands, called Intensive Home Treatment (IHT), is a viable intervention which may help reduce hospital admission days. However, research on the (cost-)effectiveness of alternatives to hospitalisation such as IHT are scarce. In the study presented in this protocol, IHT will be compared to care-as-usual (CAU) in a randomized controlled trial (RCT). CAU comprises low-intensity outpatient care and hospitalisation if necessary. In this RCT it is hypothesized that IHT will reduce inpatient days by 33% compared to CAU while safety and clinical outcomes will be non-inferior. Secondary hypotheses are that treatment satisfaction of patients and their relatives are expected to be higher in the IHT condition compared to CAU.

METHODS

A 2-centre, 2-arm Zelen double consent RCT will be employed. Participants will be recruited in the Amsterdam area, the Netherlands. Clinical assessments will be carried out at baseline and at 6, 26 and 52 weeks post treatment allocation. The primary outcome measure is the number of admission days. Secondary outcomes include psychological well-being, safety and patients' and their relatives' treatment satisfaction. Alongside this RCT an economic evaluation will be carried out to assess the cost-effectiveness and cost-utility of IHT compared to CAU.

DISCUSSION

RCTs on the effectiveness of crisis treatment in psychiatry are scarce and including patients in studies performed in acute psychiatric crisis care is a challenge due to the ethical and practical hurdles. The Zelen design may offer a feasible opportunity to carry out such an RCT. If our study finds that IHT is a safe and cost-effective alternative for CAU it may help support a further decrease of in-patient bed days and may foster the widespread implementation of IHT by mental health care organisations internationally.

TRIAL REGISTRATION

The trial is registered in the Netherlands Trial Register as # NTR-6151 . Registered 23 November 2016.

A protocol in action: Recovery approach for patients within high secure care: A 20+ year follow-up

OBJECTIVES

A person-centred approach to recovery is increasingly represented within mainstream mental health literature. Little examination of recovery among forensic mental health patients is evidenced. This study plans to address that insufficiency.

METHODS

This protocol paper details a novel approach to exploring recovery among a cohort of 241 patients detained under conditions of high secure care in Scotland during August 1992 to August 1993. Under discussion is the repurposing of previous research to circumnavigate length of inpatient stay commonly associated with forensic mental health care. The methodology adopted, while considering data leakage given the vulnerable participant group, will be discussed.

RESULTS

Repurposing and extending previous research attempts to address the file cabinet effect with 85% of health care research being wasted and future uncertainty regarding research funding in a post-Brexit era. This is an ongoing study. Ethical, confidentiality, privacy issues, and permissions are considered within the methodology.

CONCLUSIONS

Ethical arguments can be made for tracing and attempting contact with vulnerable groups under-represented in the literature. A well-considered methodology putting the focus on participant welfare and confidentiality at every step is essential. The reported methodology provides an opportunity to expand and re-examine previously collected data through a contemporary lens.

Cost comparison of zuclopenthixol acetate and haloperidol

This prospective, sequential study compared the costs of using haloperidol or zuclopenthixol acetate for rapid tranquillisation. In the first phase, all 16 patients admitted to our psychiatric intensive care unit requiring rapid tranquillisation received haloperidol; in the second phase, all 26 such patients received zuclopenthixol acetate. Mean overall costs per patient were substantially lower in the zuclopenthixol acetate group than the haloperidol group, mainly because special nursing was used much less in the zuclopenthixol acetate group. All nursing staff preferred to use zuclopenthixol acetate rather than haloperidol. Zuclopenthixol acetate could potentially reduce the need for special nursing and produce valuable cost savings.

Perceiving the evil eye: Investigating hostile interpretation of ambiguous facial emotional expression in violent and non-violent offenders

Research into the causal and perpetuating factors influencing aggression has partly focused on the general tendency of aggression-prone individuals to infer hostile intent in others, even in ambiguous circumstances. This is referred to as the ‘hostile interpretation bias’. Whether this hostile interpretation bias also exists in basal information processing, such as perception of facial emotion, is not yet known, especially with respect to the perception of ambiguous expressions. In addition, little is known about how this potential bias in facial emotion perception is related to specific characteristics of aggression. In the present study, conducted in a penitentiary setting with detained male adults, we investigated if violent offenders (n = 71) show a stronger tendency to interpret ambiguous facial expressions on a computer task as angry rather than happy, compared to non-violent offenders (n = 14) and to a control group of healthy volunteers (n = 32). We also investigated if hostile perception of facial expressions is related to specific characteristics of aggression, such as proactive and reactive aggression. No clear statistical evidence was found that violent offenders perceived facial emotional expressions as more angry than non-violent offenders or healthy volunteers. A regression analysis in the violent offender group showed that only age and a self-report measure of hostility predicted outcome on the emotion perception task. Other traits, such as psychopathic traits, intelligence, attention and a tendency to jump to conclusions were not associated with interpretation of anger in facial emotional expressions. We discuss the possible impact of the study design and population studied on our results, as well as implications for future studies.

Associations between psychiatric symptoms and seclusion use: Clinical implications for care planning

Findings from an increasing number of studies suggest that incorporating systematic short-term risk assessments in treatment planning could lead to safer practice on psychiatric admissions wards. The aim of the present study was to investigate the associations between the scores of three structured observation tools - the Kennedy Axis V (K-Axis-V), the Brief Psychiatric Rating Scale (BPRS), and the Social Dysfunction and Aggression Scale (SDAS) - and seclusion. In total, 1840 weekly risk assessments with these observation scales were collected over 2342 admission weeks. These assessment scores related to 370 acutely-admitted psychiatric patients and were subjected to a multilevel analysis. It was found that several dynamic and static factors were related to seclusion. Dynamic factors included violent behaviour, current substance abuse, suspiciousness, and negativism. Static factors included ethnicity and having been diagnosed with a substance abuse disorder. The findings suggest that the incorporation of the Kennedy-Axis V, the BPRS, and the SDAS into standard practice might be helpful in identifying patients at high risk of seclusion, and could be supportive to treatment planning and clinical decision-making in the prevention of seclusion use in acute psychiatric settings.

Generalized hostile interpretation bias regarding facial expressions: Characteristic of pathological aggressive behavior

Individuals with aggression regulation disorders tend to attribute hostility to others in socially ambiguous situations. Previous research suggests that this "hostile attribution bias" is a powerful cause of aggression. Facial expressions form important cues in the appreciation of others' intentions. Furthermore, accurate processing of facial expressions is fundamental to normal socialization. However, research on interpretation biases in facial affect is limited. It is asserted that a hostile interpretation bias (HIB) is likely to be displayed by individuals with an antisocial (ASPD) and borderline personality disorder (BPD) and probably also with an intermittent explosive disorder (IED). However, there is little knowledge to what extent this bias is displayed by each of these patient groups. The present study investigated whether a HIB regarding emotional facial expressions was displayed by forensic psychiatric outpatients (FPOs) and whether it was associated with ASPD and BPD in general or, more specifically, with a disposition to react with pathological aggression. Participants of five different groups were recruited: FPOs with ASPD, BPD, or IED, non-forensic patients with BPD (nFPOs-BPD), and healthy, non-aggressive controls (HCs). Results suggest that solely FPOs with ASPD, BPD, or IED exhibit a HIB regarding emotional facial expressions. Moreover, this bias was associated with type and severity of aggression, trait aggression, and cognitive distortions. The results suggest that a HIB regarding facial expressions is an important characteristic of pathological aggressive behavior. Interventions that modify the HIB might help to reduce the recurrence of aggression. Aggr. Behav. 43:386-397, 2017. © 2017 Wiley Periodicals, Inc.

Effects of a behaviour management technique for nursing staff on behavioural problems after acquired brain injury

The ABC method is a behaviour management technique for use by nurses. ABC refers to the identification of Antecedent events, target Behaviours, and Consequent events. In this longitudinal intervention study with double baseline measurements we evaluated the effectiveness of the ABC method in patients with behavioural problems after acquired brain injury. Fifty-six patients participated in this study. Outcome was measured in terms of overall neuropsychiatric problem behaviour, aggression, apathy and emotional burden experienced by nurses. A process evaluation was performed to investigate usability and acceptability of the method and identify factors that influenced effectiveness. Friedman's ANOVA showed a small significant reduction over time in overall neuropsychiatric problem behaviour and aggression. The reduction was most prominent between the first baseline measurement and the post-implementation and follow-up measurements, not between the second baseline measurement and the post-implementation or follow-up measurements. This first group study on the effects of the ABC method could not prove this technique is effective for patients with behavioural problems after acquired brain injury. Nurses indicated that the ABC method was not fully implemented in their daily routines. This may have influenced results and makes it yet premature to draw firm conclusions on the effects of the ABC method.

Critical incidents and judicial response during medium security treatment

This study examined inpatient incidents in three Flemish forensic medium security units and analyzed the subsequent judicial reactions to these incidents. During medium security treatment, incidents were reported for more than half of the participants. The most frequently registered incidents were non-violent in nature, such as absconding and treatment non-compliance. The base rate for physically violent incidents was low. Although crime-related incidents during medium security treatment were rarely prosecuted and adjudicated, the base rate of revocation - and hence drop-out from treatment - as a result of these incidents was high.

Biased Symptom Reporting and Antisocial Behaviour in Forensic Samples: A Weak Link

In two studies (one with 57 forensic inpatients and one with 45 prisoners) the connection between biased symptom reporting and antisocial behaviour is explored. The findings are as follows: 1) the association between symptom over-reporting and antisocial features is a) present in self-report measures, but not in behavioural measures, and b) stronger in the punitive setting than in the therapeutic setting; and 2) participants who over-report symptoms a) are prone to attribute blame for their offence to mental disorders, and b) tend to report heightened levels of antisocial features, but the reverse is not true. The data provide little support for the inclusion of antisocial behaviour (i.e. antisocial personality disorder) as a signal of symptom over-reporting (i.e. malingering) in the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5). The empirical literature on symptom over-reporting and antisocial/psychopathic behaviour is discussed and it is argued that the utility of antisocial behaviour as an indicator of biased symptom reporting is unacceptably low.

Validation of the Novaco Anger Scale–Provocation Inventory (Danish) With Nonclinical, Clinical, and Offender Samples

Anger has high prevalence in clinical and forensic settings, and it is associated with aggressive behavior and ward atmosphere on psychiatric units. Dysregulated anger is a clinical problem in Danish mental health care systems, but no anger assessment instruments have been validated in Danish. Because the Novaco Anger Scale and Provocation Inventory (NAS-PI) has been extensively validated with different clinical populations and lends itself to clinical case formulation, it was selected for translation and evaluation in the present multistudy project. Psychometric properties of the NAS-PI were investigated with samples of 477 nonclinical, 250 clinical, 167 male prisoner, and 64 male forensic participants. Anger prevalence and its relationship with other anger measures, anxiety/depression, and aggression were examined. NAS-PI was found to have high reliability, concurrent validity, and discriminant validity, and its scores discriminated the samples. High scores in the offender group demonstrated the feasibility of obtaining self-report assessments of anger with this population. Retrospective and prospective validity of the NAS were tested with the forensic patient sample regarding physically aggressive behavior in hospital. Regression analyses showed that higher scores on NAS increase the risk of having acted aggressively in the past and of acting aggressively in the future.

Predicting inpatient aggression by self-reported impulsivity in forensic psychiatric patients

BACKGROUND

Empirical knowledge of 'predictors' of physical inpatient aggression may provide staff with tools to prevent aggression or minimise its consequences.

AIM

To test the value of a self-reported measure of impulsivity for predicting inpatient aggression.

METHODS

Self-report measures of different domains of impulsivity were obtained using the Urgency, Premeditation, Perseverance, Sensation seeking, Positive urgency (UPPS-P) impulsive behaviour scale with all 74 forensic psychiatric inpatients in one low-security forensic hospital. Aggressive incidents were measured using the Social Dysfunction and Aggression Scale (SDAS). The relationship between UPPS-P subscales and the number of weeks in which violent behaviour was observed was investigated by Poisson regression.

RESULTS

The impulsivity domain labelled 'negative urgency' (NU), in combination with having a personality disorder, predicted the number of weeks in which physical aggression was observed by psychiatric nurses. NU also predicted physical aggression within the first 12 weeks of admission.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The results indicate that NU, which represents a patient's inability to cope with rejection, disappointments or other undesired feelings, is associated with a higher likelihood of becoming violent while an inpatient. This specific coping deficit should perhaps be targeted more intensively in therapy. Self-reported NU may also serve as a useful adjunct to other risk assessment tools and as an indicator of change in violence risk. Copyright © 2015 John Wiley & Sons, Ltd.

Relationships of diet-related blood parameters and blood lead levels with psychopathology and aggression in forensic psychiatric inpatients

BACKGROUND

Earlier studies have suggested associations between diet-related blood parameters and both aggression and psychopathological symptoms, but little is known about this in forensic psychiatric inpatients.

AIM

This article aims to explore the levels of diet-related blood parameters and their relationship to aggressive behaviour and/or psychopathology among Dutch forensic psychiatric inpatients.

METHODS

Minerals, vitamins, lead and fatty acid levels were measured in blood samples from 51 inpatients, well enough to consent and participate in the study, from a possible total of 99. Levels of aggression and psychopathology were assessed using questionnaires, observation instruments and clinical data. Associations between blood parameters and behavioural measures were calculated.

RESULTS

Low average levels of vitamin D3 and omega (ω)-3 fatty acids were found, with nearly two-thirds of the patients having below recommended levels of D3 , while vitamin B6 levels were high. Magnesium, iron, zinc, copper and lead were overall within reference values, but copper/zinc ratios were high. Several significant associations between levels of fatty acid measures and both aggression and psychopathology were observed.

CONCLUSION

In our sample of forensic psychiatric inpatients, fatty acids - but not mineral or vitamin levels - were associated with aggression and psychopathology. A potentially causal link between fatty acids and aggression could be tested in a randomised, placebo-controlled trial of fish oil supplements. General health of such patients might be improved by better vitamin D status (increased sun exposure and/or supplement use) and better ω-3 fatty acid status (oily fish or fish oil consumption), but discouraging unnecessary self-prescription of B vitamins where necessary.

Positive symptoms, substance use, and psychopathic traits as predictors of aggression in persons with a schizophrenia disorder

It is still not clear what the unique contribution of particular psychopathological factors is in explaining aggression in schizophrenia. The current study examined whether persecutory ideations, psychopathy and substance use are associated with different measures of aggressive behavior. We expected that persecutory ideations are associated with reactive aggression, and psychopathic traits are more associated with proactive aggression of inpatients. 59 inpatients with schizophrenia were included. Persecutory ideations we assessed using the Persecutory Ideation Questionnaire (PIQ), psychopathic traits with the revised version of Psychopathic Personality Inventory (PPI-R) and substance use was assessed using the Comprehensive Assessment of Symptoms and History (CASH). In addition, aggression was measured with the Reactive and Proactive Aggression Questionnaire (RPQ), in an experimental task using the Point Subtraction Aggression Paradigm (PSAP) and on the ward using the Social Dysfunction and Aggression Scale (SDAS). Results showed that psychopathy explains most of the variance in self-reported proactive and reactive aggression. In contrast, persecutory ideations explain most of the variance in observed aggression on the ward. Results implicate that it is important to acknowledge comorbid factors in patients with schizophrenia for more precise risk assessment and appropriate treatment for aggressive patients with schizophrenia.

Influence of Music Therapy on Coping Skills and Anger Management in Forensic Psychiatric Patients: An Exploratory Study

The effect of music therapy on anger management and coping skills is an innovative subject in the field of forensic psychiatry. This study explores the following research question: Can music therapy treatment contribute to positive changes in coping skills, anger management, and dysfunctional behavior of forensic psychiatric patients? To investigate this question, first a literature review is offered on music therapy and anger management in forensic psychiatry. Then, an explorative study is presented. In the study, a pre- and post-test design was used with a random assignment of patients to either treatment or control condition. Fourteen participants' complete datasets were collected. All participants received "treatment as usual." Nine of the participants received a standardized, music therapy anger management program; the five controls received, unplanned, an aggression management program. Results suggested that anger management skills improved for all participants. The improvement of positive coping skills and diminishing of avoidance as a coping skill were measured to show greater changes in music therapy participants. When controlling for the exact number of treatment hours, the outcomes suggested that music therapy might accelerate the process of behavioral changes.

Substance use disorders in forensic psychiatric patients

There is a lack of detailed information on the role of substance use disorders (SUD) as a substantial factor in offences and treatment in forensic psychiatric patients. The aim of this study was to get a better understanding of these specifics. Clinical records of 193 male patients admitted to a Dutch forensic psychiatric hospital were scrutinized on anamnestic, diagnostic and risk assessment data. One of the central findings was that the prevalence of SUDs was high. Patients with an SUD had a more extensive criminal history, unstable and deviant lifestyle and higher risk of violent behavior than patients without a substance use disorder. No differences were found in duration of treatment, aggressive incidents and leave. Another important finding was that a distinction could be made between patients with substance use as a primary criminogenic risk factor and patients with substance use as a secondary risk factor. Although substance use is identified as a general risk factor, this study supports the idea of sub categorization of patients with an SUD and emphasizes the need for a different treatment approach. Further study is needed to identify specific treatment approaches, based on more differentiated profiles of these patients.

Reversible antisocial behavior in ventromedial prefrontal lobe epilepsy

Frontal lobe dysfunction is known to be associated with impairment in social behavior. We investigated the link between severe pharmacoresistant frontal lobe epilepsy and antisocial trait. We studied four patients with pharmacoresistant epilepsy involving the prefrontal cortex, presenting abnormal interictal social behavior. Noninvasive investigations (video-EEG, PET, MRI) and intracerebral recording (stereoelectroencephalography (SEEG)) were performed as part of a presurgical assessment. Comprehensive psychiatric and cognitive evaluation was performed pre- and postoperatively for frontal lobe epilepsy, with at least 7years of follow-up. All patients shared a characteristic epilepsy pattern: (1) chronic severe prefrontal epilepsy with daily seizures and (2) an epileptogenic zone as defined by intracerebral recording involving the anterior cingulate cortex, ventromedial PFC, and the posterior part of the orbitofrontal cortex, with early propagation to contralateral prefrontal and ipsilateral medial temporal structures. All patients fulfilled the diagnostic criteria (DSM-IV) of antisocial personality disorder, which proved to be reversible following seizure control. Pharmacoresistant epilepsy involving a prefrontal network is associated with antisocial personality. We hypothesize that the occurrence of frequent seizures in this region over a prolonged period produces functional damage leading to impaired prefrontal control of social behavior. This functional damage is reversible since successful epilepsy surgery markedly improved antisocial behavior in these patients. The results are in line with previous reports of impairment of social and moral behavior following ventromedial frontal lobe injury.

Cognitive functions and cognitive styles in young euthymic patients with bipolar I disorder

BACKGROUND

Recent evidences suggest that bipolar disorder patients do not return to premorbid functioning levels during the inter-episode periods. Cognitive deficits may impair patients working and functioning status and may also have negative impact on other aspects of thinking.

OBJECTIVES

To assess the prevalence of cognitive dysfunction in patients with bipolar disorder in euthymic state and to explore any evident cognitive style problems.

METHOD

Case-control naturalistic study 60 patients with bipolar I disorder in euthymic state according to DSM-IV were recruited and subdivided into two groups each contains of 30 patients; (Group BPM) euthymic patients with recent manic episode, and Group BPD euthymic patients with recent depressive episode. Both groups were further compared with control group (Group C) consisted of 30 frequency matched healthy volunteers. Groups were subjected to the following: 1-clinical psychiatric examination, 2-Hamilton Depression Scale (HAMD-17) and Bech-Rafaelsen Melancholia Scale (MES) for patients' group (BPD), 3-Young Mania Rating Scale (YMRS) and Bech-Rafaelsen Mania Scale (MAS) for patients' group (BPM), 4-assessment of euthymic state of mood included both MAS and MES, 5-MMSE, MTS and CDT were performed to assess cognitive functions, 6-cognitive styles evaluation included Fear of Failure, Hopelessness Scale, (the Social Dysfunction and Aggression Scale SDAS-9 and Arabic Anger Scale.

RESULTS

Definite cognitive function impairment and different patterns of cognitive style were detected in case groups. MMSE, MTS and CDT scores were statistically significant. Fear of Failure Scale Scores were higher in BPM; 16 (53.33%) reported severe intensity compared to 16 (53.33%) of BPD Group reporting moderate intensity and 30 (100%) of the control group reporting only mild intensity of fear of failure with statistically significant differences. Although patients were in euthymic state; Hopelessness Scale discriminated between those with affective disorders and controls and other scores for hostility SADS-9 and Arabic Anger Scale. Moreover, measures of cognitive styles showed differences among patients of the case groups who joined psychotherapy program in their management (28) compared to those who did not (32).

LIMITATION

Cognitive impact of psychotropic drugs could not be eliminated since the current study is naturalistic study.

CONCLUSIONS

Those with BAD in euthymic state suffer from cognitive dysfunction and some aspects of cognitive styles that may negatively interfere with their performance. Psychotherapeutic programs should consider these findings in their approaches for better impact on patients' quality of life and overall treatment outcome.

Delusional distress partly explains the relation between persecutory ideations and inpatient aggression on the ward

Previous research showed that there is an association between persecutory delusions and inpatient aggression. However, it is not clear why some persons act upon their delusions with aggression. Research showed that persons with persecutory delusions have higher levels of delusional distress resulting from these delusions. This may explain why some persons act upon their delusions. Persecutory ideations lead to ideational distress which in turn can lead to aggression. The main aim of the present study was to test whether persecutory ideations have an indirect effect on inpatient aggression through delusional distress. The sample of the study consisted of 44 male inpatients from different general psychiatric inpatient wards. Results showed that the effect of persecutory ideations on inpatient aggression was partly explained by the level of delusional distress. Insight in the theory of acting upon delusions can be obtained by acknowledging this role of delusional distress in the relation between persecutory ideation and inpatient aggression. Early diagnosis of persecutory ideations and experienced delusional distress can be used in risk assessment of inpatients. Early interventions to reduce delusional distress, such as cognitive behavioral therapy, may prevent inpatient aggression.

Assessing aggressive behavior in forensic psychiatric patients: validity and clinical utility of combining two instruments

OBJECTIVES

Accurate observation of aggressive behavior among forensic psychiatric patients requires valid instruments. This study examines the validity and clinical utility of combining the social dysfunction and aggression scale (SDAS) and staff observation aggression scale revised (SOAS-R).

METHODS

Nurses weekly obtained SDAS scores of 127 patients, resulting in 6.124 assessments. Aggressive incidents were documented by the SOAS-R. Internal consistency, subscale structure, interobserver reliability of the SDAS, and convergent validity with SOAS-R were analyzed.

CONCLUSION

A three-factor solution was found. Interobserver reliability was moderate, and good convergent validity was found. The SDAS, in conjunction with the SOAS-R, monitors changes in aggressiveness and may contribute to the prevention of aggressive behavior.
