Psychosis and violence: stories, fears, and reality

Gender differences in first episode psychosis: Some arguments to develop gender specific treatment strategies

INTRODUCTION

Some aspects of gender differences in patients with schizophrenia spectrum disorders (SSD) have been studied, especially in cross-sectional designs and with a short-term follow-up. However, only a few studies have considered the evolution during the follow-up of SSD patients according to their gender. In this study, we explore gender differences from the time of entry in an early intervention program for psychosis, up to three years follow-up.

METHODS

We conducted a prospective study including a cohort of 474 patients treated at the Treatment and Early Intervention in Psychosis (TIPP) program, 319 men and 155 women, having presented a first episode of psychosis (FEP). Data regarding premorbid and baseline sociodemographic, psychopathological and patient functioning, were collected. These data were reassessed longitudinally after 2, 6, 12, 18, 24, 30 and 36 months after entry in TIPP.

RESULTS

Regarding premorbid and baseline characteristics, woman developed threshold symptoms of a FEP 1 year later than men on average. Women were more likely to be married, men were more likely to live in pension or care home facility or to be homeless. Women displayed a higher rate of history of suicide attempts and exposure to childhood trauma, while men were more likely to have a forensic history, a history of abuse of alcohol and cannabis as well as a dependency to cannabis at the time of entry in TIPP. Regarding evolution, men were more prone to violent acts and were less likely to decrease their usage of substances. The longitudinal analysis highlighted that men displayed greater negative symptoms over the entire treatment period, lower functioning after 6 months and on all assessment points after. Both genders displayed similar rate of improvement in these 3 dimensions over time.

CONCLUSION

Our study confirms that there are some gender differences in the early phase of psychosis that may require differentiation of assessment and treatment to improve recovery.

Association Between Adverse Childhood Experiences and a Combination of Psychosis and Violence Among Adults: A Systematic Review and Meta-Analysis

Relationships have been well established between adverse childhood experiences (ACEs) and later psychosis (29 systematic reviews) or violence (4 systematic reviews). To date, just one review has explored childhood maltreatment, specifically, and violence risk with psychosis. We conducted a systematic review and meta-analyses of a wider range of ACEs and later psychosis with actual violence compared with psychosis alone, violence alone or neither, completing searches in January 2021. In all, 15 studies met inclusion criteria, but only six included all four groups of interest. Two substantial studies recorded ACEs from sources independent of those affected and probably before emergent psychosis or violence; others relied on retrospective recall. Meta-analyses were possible only for within-psychosis-group comparisons; histories of physical abuse, sexual abuse, and having a criminal/violent parent or living with family alcohol/drug use were each associated with around twice the odds of psychosis with violence as psychosis alone. Although ACE measures in the four-way comparisons were too divergent for firm conclusions, abuse histories, and parental criminality emerged as likely antecedents, one study evidencing psychosis as mediating between ACEs and violence. Without longitudinal prospective study, pathways between ACEs and later problems remain unclear. Our findings add weight to the case for exploring ACEs in addition to abuse as possible indicators of later violence among people with psychosis and for trauma-informed interventions, which is important because some people are reluctant to disclose abuse histories.

Identifying risk factors to predict violent behaviour in community patients with severe mental disorders: A retrospective study of 5277 patients in China

BACKGROUND

Patients with Severe Mental Disorders (SMD) have a higher risk of violent behaviour than the general population. The study aimed to investigate the predictive factors for the occurrence of violent behaviour in community SMD patients.

METHODS

The cases and follow-up data were collected from SMD patient Information Management system in Jiangning District, Jiangsu Province. The incidence of violent behaviours was described and analyzed. Logistic regression model was used to examine the influencing factors for violent behaviours in those patients.

RESULTS

Among 5277 community patients with SMD in Jiangning District, 42.4% (2236/5277) had violent behaviours. The stepwise logistic regression analysis revealed that the disease-related factors (including disease type, disease course, times of hospitalization, medication adherence, past violent behaviours), the demographic factors (age, male sex, educational level, economic and social living status), and the policy-related factors (like free treatment, annual physical check, disability certificate, family physician services, and community interviews) were significantly related to the violent behaviours in community SMD patients. After gender stratification, we found that male patients with unmarried status and with a longer course of disease were more likely to violent. However, we found that female patients with lower economic status and educational experience were more likely to violent.

CONCLUSION

Our results suggest that community SMD patients had a high incidence of violent behaviour. The findings may provide valuable information for policymakers and mental health professionals worldwide taking a number of measures to reduce the incidence of violence in community SMD patients and to better maintain social security.

Sex offending among adolescents and young men with history of psychiatric inpatient care in adolescence

BACKGROUND

Some mental disorders have been associated with increased likelihood of sexual offending in adolescents (and adults), but relevant studies tend to be of established sex offenders.

AIMS

To examine relationships between adolescent mental disorders and subsequent involvement in sex offending and to explore any predictive value of primary diagnoses for subsequent interpersonal offending, whether sexual or violent.

METHODS

We analyse national register-based longitudinal data on males in Finland admitted for their first psychiatric inpatient treatment between the ages of 13-17 in the period 1980-2010 (N = 6749). Cox regression was used for the analysis of multivariate associations.

RESULTS

A subsequent criminal record for sex crime in the 10-year follow up was rare among former child and adolescent psychiatric (CAP) inpatient males (1.5%). Having a subsequent criminal record for non-sex-related violent crime was more common (25%). Time to either sex crimes or non-sex-related violent crimes after a first CAP inpatient treatment was 3-4 years. Whilst the risk of committing non-sex-related violent crimes was elevated in all diagnostic groups compared to those with schizophrenia spectrum disorders, the risk of committing subsequent sex crimes was elevated only in the group with substance use, conduct or personality disorders. Among those with pre-existing criminal history of sex crime, the risk of a subsequent criminal record for sex crime after CAP treatment was increased 11-fold, but the risk for later non-sex-related violent crimes was not increased compared to the rest of the male adolescent CAP population.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

In this first longitudinal study of criminal convictions for sex offending after a period of inpatient psychiatric treatment as an adolescent such convictions were rare, but the difference in post discharge risk of further convictions for sexual offending and non-sexual violent offending raises questions about whether more attention and specific treatment for aberrant sexual behaviours is needed for male adolescents with severe mental disorders.

Psychotic symptoms in mass shootings v. mass murders not involving firearms: findings from the Columbia mass murder database

BACKGROUND

Mass shootings account for a small fraction of annual worldwide murders, yet disproportionately affect society and influence policy. Evidence suggesting a link between mass shootings and severe mental illness (i.e. involving psychosis) is often misrepresented, generating stigma. Thus, the actual prevalence constitutes a key public health concern.

METHODS

We examined global personal-cause mass murders from 1900 to 2019, amassed by review of 14 785 murders publicly described in English in print or online, and collected information regarding perpetrator, demographics, legal history, drug use and alcohol misuse, and history of symptoms of psychiatric or neurologic illness using standardized methods. We distinguished whether firearms were or were not used, and, if so, the type (non-automatic v. semi- or fully-automatic).

RESULTS

We identified 1315 mass murders, 65% of which involved firearms. Lifetime psychotic symptoms were noted among 11% of perpetrators, consistent with previous reports, including 18% of mass murderers who did not use firearms and 8% of those who did (χ2 = 28.0, p < 0.01). US-based mass shooters were more likely to have legal histories, use recreational drugs or misuse alcohol, or have histories of non-psychotic psychiatric or neurologic symptoms. US-based mass shooters with symptoms of any psychiatric or neurologic illness more frequently used semi-or fully-automatic firearms.

CONCLUSIONS

These results suggest that policies aimed at preventing mass shootings by focusing on serious mental illness, characterized by psychotic symptoms, may have limited impact. Policies such as those targeting firearm access, recreational drug use and alcohol misuse, legal history, and non-psychotic psychopathology might yield more substantial results.

Pathways to aggression and violence in psychosis without longstanding antisocial behavior: A review and proposed psychosocial model for integrative clinical interventions

There is a need for a clearer understanding of the factors associated with increased risk of aggression and violence (AV) among people with psychosis and other severe mental illness (SMI) to guide effective prevention and intervention. The current article (1) reviews the literature regarding psychosocial factors associated with AV among individuals with psychosis and other SMI who do not have longstanding antisocial behaviors, (2) proposes an integrative psychosocial model of AV that can be practically applied, and (3) proposes appropriate evidence-based clinical interventions to reduce AV and facilitate recovery. We propose that increased risk for AV among people with psychosis is driven by anger, which is affected by a range of factors including victimization and situational stressors, social rejection or experiences of discrimination, anxious arousal, and hostile attribution bias related to psychosis. The cumulative effect of these systems is exacerbated by co-occurring substance misuse and increased impulsivity, particularly negative urgency. In consideration of the current psychosocial model and existing evidence-based interventions for AV in individuals with psychosis, we propose that trauma-informed interventions that integrate skills training in emotion regulation, social and interpersonal situations, cognitive restructuring and remediation, and modified prolonged exposure may demonstrate the most promise for this population.

The Association Between Serious Mental Health Problems and Violence: Some Common Assumptions and Misconceptions

The media, the general public, and politicians often emphasize that mental illness is a precursor and a cause of violence, particularly emphasizing an assumed relationship between mental illness, including psychopathy and psychosis, and the use of guns to commit violence. We report which individuals with serious mental health problems have an increased risk to commit violence (including gun violence). Second, we answer the question to what extent serious mental health problems explain most violence and especially gun-related violence. And what is the opinion of experts on these questions? Third, we review which effective screening instrument can help to identify individuals with mental health problems who are at risk to carry a gun and commit violence. For policy makers and legislators, this article points out that most psychiatric disorders are not related to violence, with some exceptions such as schizophrenia and bipolar disorder, and often only in conjunction with substance use. We show that the attributable risk of mental illness to explain violence in general is low. We also emphasize that conduct disorder in late childhood or adolescence is a better predictor of violence than is mental illness at a later age. Empirically based screening methods to identify individuals with mental health problems who are prone to violence appear to have limited utility. Implications are discussed for clinicians and practitioners working in the justice system, researchers, and policy makers.

The last taboo: The experience of violence in first-episode psychosis caregiving relationships

OBJECTIVES

Informal caregiving relationships play an important role in facilitating recovery outcomes in psychosis. The relationship can serve as a source of positive experiences that co-exist alongside common challenges typically associated with mental health problems. People with psychosis, when compared to the general population, are more likely to perpetrate acts of violence, a relationship that is particularly evident during the first psychosis episode. Although victims of service user violence are typically people already known to them, such as informal carers, there remains a lack of understanding about their caring experiences and needs. This study sought to address gaps in the literature by exploring the subjective accounts of informal carers supporting a relative experiencing their first episode of psychosis who has also behaved violently towards them.

DESIGN

A cross-sectional design was employed.

METHODS

Individual semi-structured interviews, which were audio recorded and later transcribed for analyses, were undertaken with a convenience sample of eight carers drawn from a specialist early psychosis service. Interview questions focused on their experiences of patient violence, the subjective impact, and coping strategies. An interpretative phenomenological approach was used to analyse the data.

RESULTS

Participants were mostly living with their relative with psychosis and were typically female, parents, and from a black and minority ethnic background. Data analyses identified seven key themes from participant interviews including the lack of predictability over when the violence occurred, being scared and fearful, keeping quiet about what happens at home and in the caregiving relationship, and staying safe.

CONCLUSIONS

Reports by informal carers about experiencing violence and victimization from their relatives with psychosis are an important issue in some caregiving relationships during the first episode. Developing a more informed understanding of the specific needs of these carers and the caregiving relationship is indicated. The implications for service providers are discussed.

PRACTITIONER POINTS

Carers were exposed to a broad range of patient violence, which included being kicked and having weapons used against them. The violence typically occurred within carers' homes, when no other people were around. Patient violence impacted negatively on carer emotional and physical functioning, which included leaving carers living in fear of their own safety and what might become of their relative. The results highlight the importance of routinely asking first-episode carers about their experience of patient violence. The development of interventions (e.g., identification of early triggers, de-escalation) that are able to take account of the ongoing nature and complexity of the caregiving relationship but are purposefully aimed at supporting carers to remain safe in their relationship should be explored for their impact.

Efficacy of typical and atypical antipsychotic medication on hostility in patients with psychosis-spectrum disorders: a review and meta-analysis

As violence against self and others is an important outcome in the treatment of patients with psychosis-spectrum disorders and hostility is an important indicator for violence, we set out to evaluate the effects of different types of antipsychotic agents in reducing hostility. We performed a systematic literature search, which provided 18 suitable randomized studies comparing typical to atypical antipsychotics for at least 4 weeks in patients with psychotic disorders. Results showed a small (0.26) but significant effect for atypical as compared to typical antipsychotics, with high heterogeneity, even though the mean dose of typical antipsychotics was higher. This effect size remained similar when separately analyzing sponsored and non-sponsored studies. When differentiating between high and low-dose studies, the high-dose group showed a significant difference between typical and atypical antipsychotics whereas the low-dose group did not. An analysis comparing clozapine to typical antipsychotics showed a moderate effect size (0.415), with low heterogeneity. These results are important for clinicians to help their shared decision making with patients when choosing maintenance treatment, as next to efficacy for psychosis and tolerability, safety for the patient and their environment is an important outcome.

Informal Caregiving Relationships in Psychosis: Reviewing the Impact of Patient Violence on Caregivers

A modest association can be found between people with a schizophrenia spectrum diagnosis (psychosis) and perpetrating acts of violence. When a person with psychosis does engage in violence, it is their informal carers, when compared to those from the general population, who are more likely to be the targets, and violence will often occur within the family home. Despite the importance of carer support for improving patient outcomes, our understanding of how carers are impacted by patient initiated violence in psychosis remains limited. This paper reviews literature documenting the effects of patient-initiated violence in psychosis on carer functioning. The review comprised searches of Medline, PsychInfo, Embase, and Web of Science databases and the hand searches of reference lists from relevant published papers. The review was limited to English language publications from inception to 11th September 2017, and where carer experiences following reports of violence from patients with psychosis were specifically recorded. Data from 20 papers using mixed methodologies were reviewed. Patient violence in psychosis was linked to poorer carer outcomes, including carer reports of burden, trauma, fear, and helplessness. There is, however, a significant need for further studies to systematically quantify the impact and correlates of patient initiated violence on psychosis caregivers, and improve prevention.

Antecedents, Behaviours, and Court Case Characteristics and Their Effects on Case Outcomes in Litigation for Persons with Schizophrenia

A 10% random sample of 3543 cases litigated in the United States' civil and criminal courts were analysed using logistic regression to develop a model that can predict case outcomes for litigants with schizophrenia. Most predictors are related to case characteristics and not to the litigants' antecedents, behaviours or medication issues. Only the psychologist as an expert witness was found to be related to case outcome, but the concern is expressed that inadequate weight is given to expert testimony. Other significant findings include being represented by counsel, atypical medication and malingering.

Prevalence and clinical correlates of police contact prior to a first diagnosis of schizophrenia

BACKGROUND

Little is known about the reasons why people with schizophrenia have contact with police, especially prior to the first episode of illness.

AIM

To investigate the prevalence and correlates of police contact in first-episode schizophrenia.

METHODS

The prevalence and type of police contact was established among all 110 patients presenting to psychiatric services in one catchment area during a first episode of schizophrenia and among 65 non-mentally ill controls, by participant and collateral interview and from records. Socio-demographic and clinical characteristics were also recorded and the two groups compared.

RESULTS

The first episode of schizophrenia patients had more contact with police than controls, despite the higher prevalence of conduct disorder symptoms among the controls. The patients were not, however, more likely to be incarcerated or arrested. Among the patients, over half of the police call-outs occurred during the period of untreated psychosis. Positive psychotic symptoms were independently associated with police contact, after allowing for socio-demographics.

CONCLUSIONS

As over a third of people in a first episode of schizophrenia had been in contact with the police - more than twice the proportion among non-psychotic controls - and contact was associated with untreated positive psychotic symptoms, better early detection and treatment of psychosis seems indicated. In the meantime, police services may be playing an important role in reducing the duration of untreated psychosis. Copyright © 2015 John Wiley & Sons, Ltd.

The relationship between paranoia and aggression in psychosis: A systematic review

Aggression in the context of schizophrenia has significant detrimental personal, clinical and societal implications. Whilst understanding the precise pathways to aggression in people with a diagnosis of schizophrenia is critical for risk management and treatment, these pathways remain unclear. A paranoid belief that others intend harm is one psychotic symptom that might contribute to aggressive behaviours. This is the first review to investigate the relationship between paranoia and aggression in psychosis. A systematic review of published literature pertinent to the relationship between paranoia and aggression was conducted. A search of online databases from inception to November 2014 was performed with keywords related to 'schizophrenia', 'paranoia' and 'aggression'. Fifteen studies, primarily cross-sectional in design (n=9), met eligibility criteria. Studies reviewed showed mixed support for an association between paranoia and aggression in both inpatients and community settings. However, when study quality was taken into account, more methodologically rigorous studies tended to show a positive association between factors. Mixed findings are most likely due to important methodological shortcomings, including heterogeneous samples and studies using a diverse range of aggression/violence measures. In light of methodological limitations of individual studies reviewed, further investigation of the relationship between paranoia and aggression in psychosis using robust methodology is needed before definitive clinical recommendations regarding the hypothesised relationship between paranoia and aggression can be made. This paper sets out key recommendations for future studies, including operationalizing the specific components of aggression and paranoia under investigation and methods to delineate important mediators in the paranoia and aggression relationship.

Associations with violent and homicidal behaviour among men with schizophrenia

Objective We aimed to assess the risk factors associated with homicidal behaviour in male patients diagnosed with schizophrenia. Methods In a period of 1 year, male schizophrenia cases between 18-65 years of age (n = 210) were included. The clinical evaluation included the Positive and Negative Syndrome Scale (PANSS) and Overt Aggression Scale (OAS). The patients were divided into three groups in terms of violent behaviour history: (1) homicide group (n = 30), (2) a violent act resulting in serious injury (n = 71), (3) control group (patients without a history of a violent act) (n = 109). Results Lower level of education, rural residence, being unemployed and living alone were found to be significantly more common in patients who had committed a violent act compared to the schizophrenia patients in the control group. In order to explore the predictive value of several factors associated with violent behaviour, a logistic regression model was used, and variables (shorter duration of education, living alone, and lack of insight) significantly predicted the presence of violent behaviour (murder and/or injury) (χ(2)=31.78, df = 12, p = 0.001). Conclusions In order to be able to determine causality of homicidal acts in schizophrenia patients, our significant findings between homicidal violence, non-homicidal violence and the control group would merit further attention and exploration in further studies.

Anti-social personality characteristics and psychotic symptoms: Two pathways associated with offending in schizophrenia

BACKGROUND

Several research groups have shown that people with schizophrenia who offend do not form a homogenous group. A three-group model claimed by Hodgins proposes distinguishing between people who start offending before the onset of psychosis (early starters), after psychosis onset but at age 34 years or under (late starters) and after psychosis onset but at age 35 years or older (late first offenders).

AIMS

This study aimed to test the hypotheses (1) that the personality of early starters and non-psychotic offenders would be similar, but different from either late-starter group; (2) that the late-starter groups would be more likely to have positive psychotic symptoms than non-criminal patients with schizophrenia; and (3) that symptom types would differentiate the psychotic groups.

METHODS

A retrospective file study was conducted on cases of 97 early starters, 100 late starters and 26 late first offenders all drawn from the Netherlands Institute of Forensic Psychiatry and Psychology (NIFP) archives 1993-2008, 115 non-psychotic offenders from 2005-2008 NIFP archives and 129 patients with schizophrenia and no criminal history from one general service in Rotterdam.

RESULTS

Early starters closely resembled the non-psychotic offenders in their premorbid anti-social personality characteristics. The two late-onset offending psychosis groups were more likely to have persecutory and/or grandiose delusions than non-offenders with psychosis, but so were the early starters.

IMPLICATIONS

In a first study to compare subgroups of offenders with psychosis directly with non-psychotic offenders and non-offenders with psychosis, we found such additional support for a distinction between early and late starters with psychosis that different treatment strategies would seem indicated, focusing on personality and substance misuse for the former but psychotic symptoms for all. It remains to be seen whether the higher rate of alcohol misuse amongst late first offenders is a fundamental distinction or a function of age difference.

Unravelling offending in schizophrenia: factors characterising subgroups of offenders

BACKGROUND

Previous studies have led to suggestions that there are at least three sub-types of offenders with schizophrenia, but these have not previously been examined simultaneously in one sample.

AIMS

The aims of this study were to investigate categorisation of offenders with psychosis as early or late starters or late first offenders, and test the hypotheses that, compared with non-offenders with psychosis, early starters would be characterised by low educational or occupational achievement, negative childhood experiences and early substance use, whereas positive psychotic symptoms would characterise late starters or late first offenders.

METHODS

A retrospective file study was conducted, yielding 97 early starters, 100 late starters and 26 late first offenders identified from a specialist inpatient forensic mental health assessment service and 129 non-offenders identified from general psychiatric services in the same geographic region, all with schizophreniform psychoses.

RESULTS

We found little difference between early and later starters in terms of measured antecedents, but substance misuse was up to 20 times less likely among late first offenders. Persecutory and/or grandiose delusions were more strongly associated with each offender group compared with non-offenders, most so with late first offenders.

CONCLUSIONS

Our findings underscore the importance of treating delusions--for safety as well as health. Childhood antecedents may be less important indicators of offender sub-types among people with psychosis than previously thought. When patients present with grandiose or persecutory delusions over the age of 35 years without co-morbid substance misuse disorders, but with a history of childhood neglect and low educational achievement, particular care should be taken to assess risk of violence.

Assessment of causal associations between illness and criminal acts in those who are acquitted by reason of insanity

BACKGROUND

The court proceedings after the terrorist attacks on 22 July 2011 reignited the debate on the justification for having a rule that regulates the insanity defence exclusively on the basis of a medical condition – the medical principle. The psychological principle represents an alternative that requires a causal relationship between the psychosis and the acts committed. In this article we investigate rulings made by the courts of appeal where the accused have been found legally insane at the time of the act, and elucidate the extent to which a causal relationship between the illness and the act appears to be in evidence.

MATERIAL AND METHOD

Data have been retrieved from rulings by the courts of appeal published at lovdata.no, which include anonymised rulings. Searches were made for cases under Section 39 (verdict of special sanctions) and Section 44 (acquittal by reason of insanity) of the General Civil Penal Code. Court rulings in which a possible causal relationship could be considered were included. The included rulings were carefully assessed with regard to whether a causal relationship existed between the mental disorder of the accused at the time and the criminal act. The search returned a total of 373 rulings, of which 75 were included.

RESULTS

The vast majority of the charges referred to serious crimes. Diagnoses under ICD-10 category codes F20-29 (schizophrenia, schizotypal and delusional disorders) were the most frequently occurring type. In 17 of the 75 rulings (23%), it was judged that no causal relationship between the illness and the act existed. In 25 of 26 cases that involved homicide, a causal relationship between the illness and the act was judged to be evident.

INTERPRETATION

The data may indicate that the medical principle results in impunity in a considerable number of rulings where the illness of the accused apparently has had no effect on the acts committed.

Risk of violence of inpatients with severe mental illness--do patients with schizophrenia pose harm to others?

Individuals suffering from schizophrenia are frequently considered to be dangerous. The current longitudinal chart review was carried out to investigate the diagnostic mix of patients who were admitted to the Department of Psychiatry and Psychotherapy at the Medical University Innsbruck due to risk of harm to others. The sample consisted of all adult inpatients admitted to psychiatric acute care units in the years 1992, 1997, 2002, and 2007. Data collection included diagnoses, criteria for risk of harm to others, and the use of mechanical restraint. Altogether, 7222 admissions were reviewed. Of these, 529 patients had to be admitted to a locked unit because of risk of harm to others. Among those mechanical restraint was more often used in patients with organic mental disorders, Cluster B personality disorders, and mania than in patients with schizophrenia. Patients suffering from schizophrenia with comorbid psychoactive substance use constitute a potentially harmful population and are therefore frequently admitted to locked units due to risk of harm to others. However, in the current study additional coercive measures were more commonly applied in patients suffering from personality disorders and organic mental disorders.

Moral cognition in schizophrenia

INTRODUCTION

Disordered moral behaviour and understanding of moral rules were described early in the literature on schizophrenia; however, moral cognition has received scant attention in spite of a large literature focused on social cognitive impairments and violent behaviour in schizophrenia.

METHODS

We conducted a narrative synthesis of the literature on violence, moral judgement and schizophrenia.

RESULTS

Initial empirical research into moral cognition in schizophrenia did not fully account for the basic- and social-cognitive deficits now known to characterise schizophrenia. Importantly, research into moral cognition in autism and psychopathy, disorders in part characterised by social cognitive impairments indicates subtle patterns of difference to the moral cognition of control participants. Recent neuroeconomic studies of moral cognition in schizophrenia have indicated that individuals with schizophrenia display subtle dysfunction in their fairness-related behaviours, but not in their propensity to engage in altruistic punishment.

CONCLUSIONS

Further research has the potential to broaden our understanding of what is intact and what is impaired in moral cognition in schizophrenia and also to inform our theories of the structures subserving moral judgement in the general population. Furthermore, a more thorough understanding of moral cognitive impairments in schizophrenia may have implications for both legal process and psychosocial rehabilitation.

First report from the Swedish National Forensic Psychiatric Register (SNFPR)

To the best of our knowledge, the present register is the only nationwide forensic psychiatric patient register in the world. The aim of this article is to describe the content of the Swedish National Forensic Psychiatric Register (SNFPR) for Swedish forensic patients for the year 2010. The subjects are individuals who, in connection with prosecution due to criminal acts, have been sentenced to compulsory forensic psychiatric treatment in Sweden. The results show that in 2010, 1476 Swedish forensic patients were assessed in the SNFPR; 1251 (85%) were males and 225 (15%) were females. Almost 60% of the patients had a diagnosis of schizophrenia, with a significantly higher frequency among males than females. As many as 70% of the patients had a previous history of outpatient psychiatric treatment before becoming a forensic psychiatric patient, with a mean age at first contact with psychiatric care of about 20 years old for both sexes. More than 63% of the patients had a history of addiction, with a higher proportion of males than females. Furthermore, as many as 38% of all patients committed crimes while under the influence of alcohol and/or illicit drugs. This was more often the case for men than for women. Both male and female patients were primarily sentenced for crimes related to life and death (e.g., murder, assault). However, there were more females than males in treatment for general dangerous crimes (e.g., arson), whereas men were more often prosecuted for crimes related to sex. In 2010, as many as 70% of all forensic patients in Sweden had a prior sentence for a criminal act, and males were prosecuted significantly more often than females. The most commonly prescribed pharmaceuticals for both genders were antipsychotics, although more women than men were prescribed other pharmaceuticals, such as antidepressants, antiepileptics, and anxiolytics. The result from the present study might give clinicians an opportunity to reflect upon and challenge their traditional treatment methods.

Angry affect and violence in the context of a psychotic illness: a systematic review and meta-analysis of the literature

A small but significant relationship between schizophrenia and violence is well established, but not yet fully explained. Research has highlighted anger as an important factor in precipitating actual violence in general and psychiatric populations. However, anger has not been extensively studied as a risk factor for violence in people with schizophrenia and related psychoses. We evaluated published evidence on the relationship between anger and violence in patients with schizophrenia and related psychoses by means of a systematic review of the literature. A search of main online databases from inception till January 2012 was performed and supplemented with correspondence with authors and data available online. 11 studies which measured angry affect in patients with schizophrenia who had been violent were included in the review. 5 studies with a total of 510 individuals had anger data that were suitable to be pooled in a meta-analysis in form of standardised mean difference values comparing the anger scores of the non-violent groups with violent groups. All the studies included showed significantly higher scores for anger in the violent group compared with the non-violent group with the pooled result expressed as standardised mean difference of 0.74 95% CI (0.53, 0.94) and the Z value for overall effect=7.01. The studies not included in the meta-analysis which looked at 610 individuals, were analysed descriptively and all of them reported higher scores for anger for individuals with schizophrenia who acted violently. There is a consistency of significant association between angry affect and violent behaviour in the context of psychotic illness across various study designs, settings and populations. Theoretical support already exists for this relationship and this review lends further support to explore this relationship further.

Symptoms associated with victimization in patients with schizophrenia and related disorders

Background

Patients with psychoses have an increased risk of becoming victims of violence. Previous studies have suggested that higher symptom levels are associated with a raised risk of becoming a victim of physical violence. There has been, however, no evidence on the type of symptoms that are linked with an increased risk of recent victimization.

Methods

Data was taken from two studies on involuntarily admitted patients, one national study in England and an international one in six other European countries. In the week following admission, trained interviewers asked patients whether they had been victims of physical violence in the year prior to admission, and assessed symptoms on the Brief Psychiatric Rating Scale (BPRS). Only patients with a diagnosis of schizophrenia or related disorders (ICD-10 F20–29) were included in the analysis which was conducted separately for the two samples. Symptom levels assessed on the BPRS subscales were tested as predictors of victimization. Univariable and multivariable logistic regression models were fitted to estimate adjusted odds ratios.

Results

Data from 383 patients in the English sample and 543 patients in the European sample was analysed. Rates of victimization were 37.8% and 28.0% respectively. In multivariable models, the BPRS manic subscale was significantly associated with victimization in both samples.

Conclusions

Higher levels of manic symptoms indicate a raised risk of being a victim of violence in involuntary patients with schizophrenia and related disorders. This might be explained by higher activity levels, impaired judgement or poorer self-control in patients with manic symptoms. Such symptoms should be specifically considered in risk assessments.

Violence in childhood-onset schizophrenia

Violence is elevated in older adolescents and adults with schizophrenia; however, little is known about younger children. This report focuses on rates of violence in younger children with schizophrenic-spectrum illnesses. A retrospective review of structured diagnostic interviews from a case series of 81 children, ages 4-15 years of age, with childhood onset of schizophrenic-spectrum illness is reported. Seventy-two percent of children had a history of violent behavior, including 25 children (31%) with a history of severe violence. Of those with a history of violence, 60% had a least one episode of violence that did not appear to be in response to an external stimulus (internally driven violence). There was no significant impact of age or gender. For many children, these internally driven violent episodes were rare and unpredictable, but severe. Similar to what is found in adolescents and adults, violence is common in children with schizophrenic-spectrum illnesses. General violence prevention strategies combined with early identification and treatment of childhood psychotic illnesses may decrease the morbidity associated with childhood psychotic violence.

The role of ideational distress in the relation between persecutory ideations and reactive aggression

BACKGROUND

People with schizophrenia are more likely to be violent than the people without it. Feeling driven to act on persecutory delusions may be one explanation for this, but it remains unclear why some should act on such delusions but some not. Acquisition of data from people who are very ill is problematic. Our study explores testing of hypotheses on similar ideational and behavioural associations among healthy recruits from the general population.

AIMS

This study aims to test the effect of distress induced by persecutory ideas on any relationships between those ideas and aggressive behaviour, and the effect of gender.

METHODS

Twenty-four men and 53 women from the general population participated in this study. The measures of aggressive behaviour were experimentally induced aggressive responding, self-reported aggressive behaviour in general, and self-reported reactive and proactive aggressive behaviours.

RESULTS

Among men, persecutory ideation predicted reactive aggressive responding and aggressive style of behaviour only in those who experienced higher levels of persecutory ideational distress. Among women, with generally lower levels of aggression, the role of ideational distress was more complicated; Women in the low distress group responded with higher aggression on the task. Women in the higher distress group responded with higher aggressive style. For neither men nor women were there links between persecutory ideation and proactive aggression, regardless of distress.

CONCLUSIONS

Ideational distress moderates the relation between persecutory ideation and aggression in different measures of aggression in men and women. IMPLICATIONS FOR PRACTICE AND/OR RESEARCH: Recognition of a relation between persecutory ideations and aggression is also important in the general population. Insight in the theory of acting upon delusions may lead to more accurate violence risk assessment. Facilitation of early detection of experienced delusional distress may lead to development of more specific psychotherapeutic interventions to manage violence risk.

Empathy, schizophrenia and violence: a systematic review

BACKGROUND

A small but significant association between schizophrenia and violence is open to a number of explanations. Impaired empathy has been associated with schizophrenia, and with violence in the general population. Our aim was to conduct a systematic review of any research into relationships between schizophrenia, empathy and violence.

METHODS

The electronic databases Medline, Psychinfo, Embase, Cochrane and DARE were searched using combinations of terms for schizophrenia, empathy and violence, as were selected journals and reference lists of relevant articles. Selection of studies and data extraction was done by each of us, blind to the other.

RESULTS

Six studies were identified, but sample selection, research procedures and empathy, illness and violence measures differed sufficiently between them that only descriptive analysis was possible. Apart from one single case study, sample sizes were between 24 (12 violent) and 116 (35 violent). A component of emotional empathy (emotion recognition) was measured in three of the studies, all of which showed some specific dysfunctional recognition related to violence. Cognitive empathy was measured in three studies, two linking impairments to violence and one not. Emotional responsiveness was measured in one study and no association with violence was found.

CONCLUSION

Although evidence is inconclusive on empathy impairment as a mediator of violence by people with chronic psychosis, it's likely relevance is most apparent in the better controlled studies. Larger scale studies are indicated with rigorous control for comorbidities.

Ethnicity, violent offending, and vulnerability to schizophrenia: a pilot study

Previous research has highlighted increased risk for schizophrenia in Afro-Caribbeans as well as over-representation in the prison population. This small-scale study examined the relationship between criminality, ethnicity, and psychosis-proneness in a male prison sample. Twenty British Caucasian and 20 Afro-Caribbean prisoners were divided into equal sub-groups of violent and non-violent offenders. Participants completed measures of schizotypy, delusional ideation, and hostility. Afro-Caribbean offenders scored more highly on negative schizotypy and delusional ideation than their Caucasian counterparts. Violent offenders scored more highly on the positive symptoms of schizotypy than non-violent prisoners. Both ethnicity and violent offending may be relevant factors when considering vulnerability to psychosis in the offending population.

Prevalence of violence risk factors in people at ultra-high risk of developing psychosis: a service audit

BACKGROUND

There is little data available on the prevalence of violence risk factors in people at ultra-high risk of developing psychosis.

AIM

The aim of this study was to provide an estimate of the cross-sectional prevalence of violence risk factors in those attending a routine clinical service for people at ultra-high risk of developing psychosis.

METHODS

The case notes of all 34 clients receiving treatment over a 4-week period were reviewed and all clinicians were interviewed. Information was gathered regarding gender, current violent ideation, history of violence (including convictions), expressions of concern from others, problems with alcohol or substance misuse, jealousy, suspiciousness, irritability, anger and relevant subthreshold psychotic symptoms. Information on protective factors, including treatment engagement, was also gathered.

RESULTS

Thirty-eight per cent (n = 13) had a history of violent behaviour, 79.4% (n = 27) were thought to be currently experiencing significant levels of suspiciousness and 47.1% (n = 16) were thought to have problems with anger. Twenty-nine per cent (n = 10) had previous known convictions for violence. Two-thirds (n = 8) of those where risk of violence was identified were described as being engaged with treatment.

CONCLUSION

There was a high prevalence of violence risk factors in this small sample. Further research with larger samples and better methodology is urgently required to investigate risk of violence in this group and determine the contribution, if any, of subclinical psychotic symptoms.

The functional anatomical distinction between truth telling and deception is preserved among people with schizophrenia

BACKGROUND

A recently emergent functional neuroimaging literature has described the functional anatomical correlates of deception among healthy volunteers, most often implicating the ventrolateral prefrontal and anterior cingulate cortices. To date, there have been no such imaging studies of people with severe mental illness.

AIMS

To discover whether the brains of people with schizophrenia would manifest a similar functional anatomical distinction between the states of truthfulness and deceit. It is hypothesised that, as with healthy people, persons with schizophrenia will show activation in the ventrolateral prefrontal and anterior cingulate cortices when lying.

METHOD

Fifty-two people satisfying Diagnostic and Statistical Manual of Mental Disorder-IV criteria for schizophrenia or schizoaffective disorder underwent functional magnetic resonance imaging at 3 T while responding truthfully or with lies to questions concerning their recent actions. Half the sample was concurrently experiencing delusions.

RESULTS

As hypothesised, patients exhibited greater activity in ventrolateral prefrontal cortices while lying. Truthful responses were not associated with any areas of relatively increased activation. The presence or absence of delusions did not substantially affect these findings, although subtle laterality effects were discernible upon post hoc analyses.

CONCLUSIONS

As in healthy cohorts, the brains of people with schizophrenia exhibit a functional anatomical distinction between the states of truthfulness and deceit. Furthermore, this distinction pertains even in the presence of delusions.

Schizophrenia, "just the facts" 4. Clinical features and conceptualization

Although dementia praecox or schizophrenia has been considered a unique disease entity for the past century, its definitions and boundaries have continued to vary over this period. At any given time, the changing concept of schizophrenia has been influenced by available diagnostic tools and treatments, related conditions from which it most needs to be distinguished, extant knowledge and scientific paradigms. There is significant heterogeneity in the etiopathology, symptomatology, and course of schizophrenia. It is characterized by an admixture of positive, negative, cognitive, mood, and motor symptoms whose severity varies across patients and through the course of the illness. Positive symptoms usually first begin in adolescence or early adulthood, but are often preceded by varying degrees of negative and cognitive symptomatology. Schizophrenia tends to be a chronic and relapsing disorder with generally incomplete remissions, variable degrees of functional impairment and social disability, frequent comorbid substance abuse, and decreased longevity. Although schizophrenia may not represent a single disease with a unitary etiology or pathogenetic process, alternative approaches have thus far been unsuccessful in better defining this syndrome or its component entities. The symptomatologic, course, and etio-pathological heterogeneity can usefully be addressed by a dimensional approach to psychopathology, a clinical staging approach to illness course, and by elucidating endophenotypes and markers of illness progression, respectively. This will allow an approach to the deconstruction of schizophrenia into its multiple component parts and strategies to reconfigure these components in a more meaningful manner. Possible implications for DSM-V and ICD-11 definitions of schizophrenia are discussed.
