Psychiatric diagnosis and aggression before acute hospitalisation

Substance Abuse Associated with Aggressive/Violent Behaviors in Psychiatric Outpatients and Related Psychotropic Prescription

Psychiatric disorders with substance abuse are considered the leading causes of most violent and aggressive behaviors in the general population. This study was aimed to assess the impact of substance abuse and the therapeutic approaches adopted by psychiatrists in aggressive vs non-aggressive outpatients (n = 400) attending community-based psychiatric services and recruited over a 3-year period. Clinical and therapeutic variables were collected from medical records and the Modified Overt Aggression Scale (MOAS) was used to assess any aggressive/violent behavior. Violent behaviors were significantly higher in alcohol and substance abusers compared to non-abusers (p < 0.01), except for heroin abusers. Mean weighted MOAS score was significantly higher in patients taking antipsychotics (p < 0.005). The administration of Haloperidol, Zuclopenthixol, and Clozapine was more frequent in aggressive than in non-aggressive patients. The most frequently administered drug in these patients was Haloperidol (23.91%), with a higher mean daily dosage in violent vs non-violent patients. Our results confirm the well-established relationship between substance abuse and violent behaviors in psychiatric inpatients also within outpatient community services. Observed rates of most frequently prescribed antipsychotics to aggressive patients did not show any preference for newer generation compounds, with clinicians operating in the community setting likely being in need for further evidence and specific training to support their treatment choice.

Effectiveness of De-Escalation in Reducing Aggression and Coercion in Acute Psychiatric Units. A Cluster Randomized Study

OBJECTIVE

Most guidelines for the management of aggressive behavior in acute psychiatric patients describe the use of de-escalation as the first-choice method, but the evidence for its effectiveness is inconsistent. The aim of the study was to assess the effect of verbal and non-verbal de-escalation on the incidence and severity of aggression and the use of physical restraints in acute psychiatric wards.

METHODS

A multi-center cluster randomized study was conducted in the acute wards of all psychiatric hospitals in Slovenia. The research was carried out in two phases, a baseline period of five consecutive months and an intervention period of the same five consecutive months in the following year. The intervention was implemented after the baseline period and included training in verbal and non-verbal de-escalation techniques for the staff teams on experimental wards.

RESULTS

In the baseline study period, there were no significant differences in the incidence of aggressive behavior and physical restraints between the experimental and control groups. The incidence rates of aggressive events, severe aggressive events, and physical restraints per 100 treatment days decreased significantly after the intervention. Compared to the control group, the incidence rate of aggressive events was 73% lower in the experimental group (IRR = 0.268, 95% CI [0.221; 0.342]), while the rate of severe events was 86% lower (IRR = 0.142, 95% CI [0.107; 0.189]). During the intervention period, the incidence rate of physical restraints due to aggression in the experimental group decreased to 30% of the rate in the control group (IRR = 0.304, 95% CI [0.238; 0.386]). No reduction in the incidence of restraint used for reasons unrelated to aggression was observed. After the intervention, a statistically significant decrease in the severity of aggressive incidents (p < 0.001) was observed, while the average duration of restraint episodes did not decrease.

CONCLUSION

De-escalation training is effective in reducing the incidence and severity of aggression and the use of physical restraints in acute psychiatric units.

Efficacy of Polyunsaturated Fatty Acids (PUFAs) on Impulsive Behaviours and Aggressiveness in Psychiatric Disorders

It is the focus of increasing interest to investigate the effects of long-chain n-3 and long-chain n-6 polyunsaturated fatty acids (LC n-3 PUFAs; LC n-6 PUFAs) on psychiatric symptoms in a transdiagnostic perspective. There is some evidence that low levels of LC n-3 PUFAs and a higher ratio of LC n-6 to LC n-3 PUFAs in plasma and blood cells are associated with aggressive and impulsive behaviours. Therefore, implementation of LC n-3 PUFAs may produce positive effects on hostility, aggression, and impulsivity in both psychiatric and non-psychiatric samples across different stages of life. A possible mechanism of action of LC n-3 PUFAs in conditions characterized by a high level of impulsivity and aggression is due to the effect of these compounds on the serotonin system and membrane stability. Studies that evaluated the effects of LC n-3 PUFAs on impulsivity and aggressiveness indicated that addition of rather low doses of these agents to antipsychotic treatment might reduce agitation and violent behaviours in psychosis, attention deficit hyperactivity disorder, personality disorders, and impulsive control and conduct disorders. The present review is aimed at examining and discussing available data from recent trials on this topic.

No Impact of Omega-3 Fatty Acid Supplementation on Symptoms or Hostility Among Patients With Schizophrenia

OBJECTIVE

This study was aimed to explore the impact of fish oil (Omega-3 fatty acids) on hostility and psychopathology among patients with acute violent schizophrenia.

METHOD

Sixty seven acute hospitalized patients demonstrating violent behavior in the context of a schizophrenic illness, treated with antipsychotics, were randomly assigned to a supplement with either fish oil (N=32) or placebo (N=35) in a double-blind, placebo-controlled trial. Assessments were conducted at the baseline, week 4 and week 8.

RESULTS

The symptoms and hostility decreased after treatment for 4 and 8 weeks in both groups, with no group differences.

CONCLUSIONS

The current study did not find improvements in symptoms or hostility from the Omega-3 fatty acid supplementation in patients with schizophrenia. The implication is that Omega-3 fatty acids do not reduce psychopathology and hostility in acute patients with schizophrenia.

Aggressiveness and violence in psychiatric patients: a clinical or social paradigm?

OBJECTIVE

Psychiatric disorders are often considered the leading cause of violence. This may be due to a stereotype created by media and general opinion.

METHOD

The Modified Overt Aggression Scale (MOAS) was used to evaluate the severity of aggressive and violent behaviors in 400 patients who attended a post-acute psychiatric service in Milan from 2014 to 2016 and suffered from different psychiatric disorders. The psychopathological clinical picture was evaluated by Clinical Global Impression (CGI). The study also assessed the possible correlation between epidemiologic and sociodemographic factors, clinical variables, and aggression and violence.

RESULTS

Of the total number of subjects, 21.50% showed a MOAS score >0, 11.50% presented mild aggression (0-10 MOAS weighted score), 9% moderate aggression (11-20), and 1% severe aggression (MOAS >20). With respect to violent behaviors, 16% of patients showed a score >0 in one MOAS subscale other than verbal aggression according to violence definition. The severity of clinical picture seemed to be related to higher weighted MOAS score. Multivariate testing of different sociodemographic and clinical variables showed that violence was related to unemployment status, and significantly correlated to compulsory admission (TSO), suicide attempts (TS), and personality disorders, while the severity of clinical psychiatric picture seemed to play a secondary role.

CONCLUSION

Results have shown that personality disorders and sociodemographic factors, including economic factors, seem to be major determinants of violence among patients diagnosed with mental disorders.

Aggression among 216 patients with a first-psychotic episode of bipolar I disorder

Background

Aggression by patients with bipolar I disorder (BD-I) is not uncommon. Identifying potential risk factors early in the illness-course should inform clinical management and reduce risk.

Methods

In a study sample of 216 initially hospitalized, first-psychotic episode subjects diagnosed with DSM-IV-TR BD-I, we identified recent (within 1 month before hospitalization) aggression by ratings on the Brief Psychiatric Rating Scale-Expanded and review of detailed clinical research records. We compared subjects with versus without aggressive behavior for associations with selected demographic and clinical factors.

Results

Aggression was identified in 23/216 subjects (10.6%). It was associated significantly with recent suicide attempt (OR = 4.86), alcohol abuse (OR = 3.63), learning disability (OR = 3.14), and initial manic episode (OR = 2.59), but not with age, sex, onset-type, personality disorder, time to recovery, or functional status.

Conclusions

Among first-major episode BD-I patients with psychotic features, recent serious aggression towards others was identified in 10.6%. The odds of aggression increased by 4.9-times in association with a recent suicide attempt, more than 3-times with alcohol-abuse or learning disability, and by 2.6-times if the episode polarity was manic. The findings encourage closer management of alcohol misuse, suicide risk, and manic symptoms, and early detection of learning problems in BD-I patients.

Mental Health Visits: Examining Socio-demographic and Diagnosis Trends in the Emergency Department by the Pediatric Population

The emergency department (ED) is increasingly being used for mental health visits by children and adolescents. It is estimated that 21-23% of youth have a diagnosable psychiatric or substance use disorder. Using data from the ED of a tertiary medical center, we examined trends in mental health diagnoses over a 5-year period. In school age children the most prevalent diagnoses were anxiety disorders (28.4%); disorders first usually diagnosed in infancy, childhood, or adolescence (26.5%), and mood disorders (18.6%). High school students were more likely to visit the ED for anxiety disorders (30%). Females (34.5%) presented more for anxiety disorders compared to males (22.7%). Mental health visits and diagnoses were higher during school months (September-May) and lower in the summer months (June-August). The diagnosis trends identified in this study have clinical implications that can contribute to evidence-based restructuring of mental health resources and screenings.

Violence and mental disorders. A retrospective study of people in charge of a community mental health center

BACKGROUND

Numerous studies conducted in inpatient settings have highlighted how mental disorders are associated with an increased risk of violence, particularly during acute phases. However, to date a more limited number of studies have been performed to assess the risk of violence in outpatients, particularly in Italy. The present study aims to evaluate the prevalence of violent events in a sample of patients in charge of a community mental health center in Italy.

METHODS

Based on data obtained from standardized clinical records, a retrospective study was undertaken to investigate acts of violence (physical aggression only) in a total of 678 patients (Males=308, 45.4%) in charge of a university mental health center; patients were mainly affected by anxiety disorders (30.7%), depressive disorder (17.2%), bipolar disorder (18.3%) and schizophrenia or other psychotic disorders (25.0%).

RESULTS

27.6% of the sample had committed at least one act of violence during their lifetime, 10.5% over the previous year. 56.7% of those who committed violence acts had acted violently twice or more during their lifetime. A significant association of lifetime violence was found with gender (male), younger age, low education, unemployment, living with parents. With regard to diagnosis, a significant association was found with schizophrenia and other psychotic disorders, personality disorders, mental retardation, and comorbidity between two or more psychiatric disorders. Violence was moreover associated with early age at onset and at first psychiatric treatment, longer duration of the disorder, previous hospital admissions, previous violent events.

CONCLUSION

Violent behavior is relatively common among outpatients.

Substance use is a risk factor for violent behavior in male patients with bipolar disorder

BACKGROUND

To determine the factors involved in violent behavior in patients with bipolar disorder (BD) and to investigate the relationship between violence and substance use disorder (SUD).

METHODS

A sample of 100 male inpatients diagnosed with BD type I who were experiencing a current mood episode participated in the study. Violent behavior was defined as physical aggression against others. All patients were evaluated using the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HDRS), Positive and Negative Syndrome Scale-positive subscale (PANSS-p), Barratt Impulsivity Scale-11 (BIS-11), Buss-Perry Aggression Questionnaire (BPAQ) and Overt Aggression Scale (OAS). Lifetime SUD and current use of substances were evaluated. Logistic regression analysis was conducted to predict violent behavior.

RESULTS

Current substance use (CSU) rather than lifetime SUD was found to be related to violent behavior in patients with BD, and CSU was associated with a threefold increase in the risk of violence. The rate of lifetime SUD in our sample was 59%, and the rate of CSU was 39%. The most commonly abused substances were cannabis and alcohol, followed by synthetic cannabinoids, in both groups of patients with lifetime SUD and CSU. Individuals abusing any substance were more likely to have a criminal record and history of incarceration than other patients. One of the most significant risk factors for violence was a previous history of violent behavior.

LIMITATIONS

The sample was limited to male patients. Data on some participants' recent substance use from standard urine analysis was not obtained. The data on the use of synthetic cannabinoids was obtained from patients and their families owing to the lack of equipment for detecting synthetic cannabinoids using laboratory analysis.

CONCLUSIONS

CSU appears to be a significant predictive factor in violent behavior in male patients. Further investigation of co-occurrence of violence with CSU and improvement in treatment strategies might reduce or prevent violence in patients with BD.

The 23-Hour Observation Unit Admissions Within the Emergency Service at a National Tertiary Psychiatric Hospital: Clarifying Clinical Profiles, Outcomes, and Predictors of Subsequent Hospitalization

OBJECTIVE

We examined health care utilization, clinical profiles (such as sociodemographic features, clinical severity), and outcomes (inpatient admission, revisit within 24 hours of discharge) of patients who were admitted to a 23-hour observation unit within the emergency service of a tertiary psychiatric hospital and hypothesized that a specific clinical profile (greater clinical severity, lower psychosocial functioning) predicted subsequent inpatient hospitalization.

METHOD

The medical records of all patients admitted to the observation unit from February 5, 2007, to February 4, 2012 (N = 2,158) were assessed for relevant data. Clinical severity and level of psychosocial functioning were assessed using Clinical Global Impressions-Severity (CGI-S) and Global Assessment of Functioning (GAF) scales, respectively.

RESULTS

Overall, the patients seen were predominantly Chinese males > 36 years old who had diagnoses including stress-related, anxiety, affective spectrum, and psychotic disorders. The clinical severity score (CGI-S) improved significantly following discharge from the observation unit (t 1,1848 = 23.316; P < .001). Logistic regression analyses revealed that self-referred (P = .001), older patients (P = .007) with past psychiatric history (P = .019), lower GAF scores (P = .025), and less improvement of CGI-S scores (P = .001) were associated with inpatient admission after a 23-hour stay in the observation unit.

CONCLUSIONS

Our study findings affirmed our hypothesis and supported the utility of the observation unit in monitoring the overall clinical status of patients, which was linked with subsequent inpatient admissions. Better management of these patients at the outpatient level can potentially decrease unnecessary hospitalization and reduce health care cost as well as illness burden on patients and caregivers.

Aggressive behavior during the first 24 hours of psychiatric admission

OBJECTIVE: To investigate the association between aggression in the first 24 hours after admission and severity of psychopathology in psychiatric inpatients.METHODS: This cross-sectional study included psychiatric patients admitted to Hospital Universitário de Santa Maria, in Santa Maria, southern Brazil, from August 2012 to January 2013. At their arrival at the hospital, patients were interviewed to fill in the Brief Psychiatric Rating Scale (BPRS) form, and any aggressive episodes in the first 24 hours after admission were recorded using the Overt Aggression Scale (OAS). The Mann-Whitney U test was used to compare patients according to aggressiveness: aggressive versus non-aggressive, hostile versus violent, and aggressive against others only versus self-aggressive.RESULTS: The sample was composed of 110 patients. Aggressive patients in general had higher BPRS total scores (p = 0.002) and individual component scores, and their results showed more activation (p < 0.001) and thinking disorders (p = 0.009), but less anxious-depression (p = 0.008). Violent patients had more severe psychomotor agitation (p = 0.027), hallucinations (p = 0.017) and unusual thought content (p = 0.020). Additionally, self-aggressive patients had more disorientation (p = 0.011) and conceptual disorganization (p = 0.007).CONCLUSIONS: Aggression in psychiatric patients in the first 24 hours after admission is associated with severity of psychopathology, and severity increases with severity of patient psychosis and agitation.

Substance use disorders in hospitalized psychiatric patients: the experience of one psychiatric emergency service in Turin

In the present study we sought: 1) to estimate the frequency of substance use disorders (SUD), and 2) to investigate whether there is a mere association between diagnosis and SUD in a large cohort of patients with severe psychiatric disorders representative of the usual setting and modality of care of a psychiatric emergency service in a geographically well-defined catchment area in Italy, independent of sociodemographic features, anamnestic data and clinical status. The study was conducted between January 2007 and December 2008. The following rating scales were performed: the Clinical Global Impression-Severity (CGI-S), the Global Assessment of Functioning scale (GAF) and the Brief Psychiatric Rating Scale (BPRS). Factors found to be associated (p<0.05) with SUD[+] in the univariate analyses were subjected to multilevel logistic regression model with a backward stepwise procedure. Among 848 inpatients of our sample 29.1% had a SUD codiagnosis. Eleven factors accounted for 30.6% of the variability in SUD[+]: [a] a Personality Disorder diagnosis, [b] a Depressive Disorder diagnosis, [c] male gender, [d] previous outpatient contacts, [e] single marital status, [f] no previous psychiatric treatments, [g] younger age, [h] lower scores for BPRS Anxiety-depression and [i] BPRS Thought Disturbance, [l] higher scores for BPRS Activation and [m] BPRS Hostile-suspiciousness. The findings are important in identifying (1) the complexity of the clinical presentation of SUD in a inpatients sample, (2) the need for collaboration among health care workers, and (3) the need to develop and apply treatment programs that are targeted at particular risk groups.

Demographics, clinical characteristics, and treatment of aggressive patients admitted to the acute behavioral unit of a community general hospital: a prospective observational study

OBJECTIVE

Aggressive patients are not uncommon in acute inpatient behavioral health units of general hospitals. Prior research identifies various predictors associated with aggressive inpatient behavior. This prospective observational study examines the demographic and clinical characteristics of aggressive inpatients and the routine medications these patients were receiving at discharge.

METHOD

Thirty-six adults diagnosed with a DSM-IV mental disorder who met 2 of 6 established inclusion criteria for high violence risk and a Clinical Global Impressions-Severity of Illness (CGI-S) scale score ≥ 4 were observed for a maximum of 28 days on the 23-bed case mix acute behavioral health unit of St Luke's University Hospital, Bethlehem, Pennsylvania, from January 2012 to May 2013. Primary outcome measures were the Modified Overt Aggression Scale (MOAS) and CGI-S; secondary measures were symptom outcome measures and demographic and clinical characteristics data. Analysis was conducted using repeated measures methodology.

RESULTS

Younger males with a history of previous violence, psychiatric admissions, and symptoms of severe agitation were more at risk for aggressive behavior. Positive psychotic symptoms, a diagnosis of bipolar disorder, substance use, and comorbid personality disorders also increased risk. Significant improvements from baseline to last visit were observed for the CGI-S and MOAS (P < .001 for both), with a significant correlation between the MOAS and CGI-S at last visit (P < .001). Only the symptom of agitation was significantly correlated to MOAS scores at both baseline and last visit (P < .001).

CONCLUSION

Patients significantly improved over time in both severity of illness and level of aggression.

Prospective longitudinal course of aggression among adults with bipolar disorder

OBJECTIVES

Bipolar disorder (BP) has been associated with increased aggressive behaviors. However, all existing studies are cross-sectional and include forensic or inpatient populations and many do not take into account the effects of comorbid conditions. The goal of this study was to evaluate the longitudinal course of aggression among adult outpatients with BP compared with non-BP patients and healthy controls.

METHODS

Subjects with bipolar I disorder (BP-I)/bipolar II disorder (BP-II) (n = 255), those with non-BP psychopathology (n = 85), and healthy controls (n = 84) (average 38.9 years, 78.7% female, and 84.9% Caucasian) were evaluated at intake and after two and four years of follow-up. Aggression was self-rated using the Aggression Questionnaire (AQ). Comparisons were adjusted for any significant demographic and clinical differences and for multiple comparisons. For subjects with BP, associations of AQ with subtype of BP, current versus past mood episodes, polarity and severity of the current episode, psychosis, and current pharmacological treatment were evaluated.

RESULTS

In comparison with subjects with non-BP psychiatric disorders and healthy controls, subjects with BP showed persistently higher total and subscale AQ scores (raw and T-scores) during the four-year follow-up. There were no effects of BP subtype, severity or polarity of the current episode, psychosis, and current pharmacological treatments. Subjects in an acute mood episode showed significantly higher AQ scores than euthymic subjects.

CONCLUSIONS

BP, particularly during acute episodes, is associated with increased self-reported verbal and physical aggression, anger, and hostility. These results provide further evidence of the need for treatments to prevent mood recurrences and prompt treatment of acute mood episodes in subjects with BP.

Adult patients with schizophrenia using violence towards their parents: a phenomenological study of views and experiences of violence in parent-child dyads

AIMS

To describe the lived experiences of aggression and violence among patients with schizophrenia and their victimized biological parent as the major caregiver being aggressed by their child (parent-adult-child dyads), and to gain an understanding of the precipitating factors influencing violence.

BACKGROUND

Child-to-parent violence, particularly in the mentally ill adult child, is arguably the most stressful and under-researched issue of family violence. Violence in patients with mental illness is most frequently targeted at family members, and most often takes place at home. Both patients and their parents' experiences of violence are relatively unexplored.

DESIGN

Qualitative study design.

METHODS

Data were collected using individual in-depth interviews between August 2010-August 2011 in Taiwan. Purposive sample of 14 hospitalized patients with schizophrenia who had aggression and violence in the past year directed towards their biological parent of either gender.

FINDINGS

Five main themes were identified: violence occurring beyond control in a particular situation translated into parent and patient's possible endangerment, the repetitive nature of violence, distress, ineffective communication, and management of violence and help-seeking. Repetitive violent episodes and tension made both the parent and patient feel uncontrollable. Parents had a perceived fear of adverse consequences such as being punished by receiving more retribution and they also had concerns related to their parental responsibility.

CONCLUSIONS

Health professionals should be aware of the complexity of phenomena and the interplay of factors inducing violence. A comprehensive dyadic parent-child intervention is suggested for violence prevention.

Is bipolar disorder specifically associated with aggression?

OBJECTIVE

Several studies have suggested that bipolar disorder (BP) in adults is associated with aggressive behaviors. However, most studies have included only inpatients and have not taken into consideration possible confounding factors. The goal of the present study was to compare the prevalence of aggression in subjects with BP compared to subjects with other, non-BP psychopathology and healthy controls.

METHODS

Subjects with bipolar I disorder (BP-I) and bipolar II disorder (BP-II) (n = 255), non-BP psychopathology (n = 85), and healthy controls (n = 84) were recruited. Aggression was measured using the Aggression Questionnaire (AQ). Group comparisons were adjusted for demographic and clinical differences (e.g., comorbid disorders) and multiple comparisons. The effects of the subtype of BP, current versus past episode, polarity of current episode, psychosis, the presence of irritable mania/hypomania only, and pharmacological treatment were examined.

RESULTS

Subjects with BP showed significantly higher total and subscale AQ scores (raw and T-scores) when compared to subjects with non-BP psychopathology and healthy controls. Exclusion of subjects with current mood episodes and those with common comorbid disorders yielded similar results. There were no effects of BP subtype, polarity of the current episode, irritable manic/hypomanic episodes only, or current use of pharmacological treatments. Independent of the severity of BP and polarity of the episode, those in a current mood episode showed significantly higher AQ scores than those not in a current mood episode. Subjects with current psychosis showed significantly higher total AQ score, hostility, and anger than those without current psychosis.

CONCLUSIONS

Subjects with BP display greater rates of anger and aggressive behaviors, especially during acute and psychotic episodes. Early identification and management of these behaviors is warranted.

Violent behaviors in drug addiction: differential profiles of drug-addicted patients with and without violence problems

This study explored the prevalence of violent behaviors in patients who are addicted to drugs. A sample of 252 addicted patients (203 male and 49 female) who sought outpatient treatment was assessed. Information on violent behaviors, sociodemographic factors, consumption factors (assessed by the European version of the Addiction Severity Index [EuropASI]), psychopathological factors (assessed by Symptom Checklist-90-Revised [SCL-90-R]), and personality variables (assessed by Millon Clinical Multiaxial Inventory [MCMI-II]) was collected. Drug-addicted patients who were associated with violent behaviors were compared on all variables with patients who were not associated with violent behaviors. The rate of drug-addicted patients with violent behaviors in this sample was 39.68% (n = 100). There were significant differences between the numbers of patients who did and did not demonstrate violence on some variables. Patients with violence problems were younger than those without violence problems and were more likely to report having been a victim of abuse. Moreover, they were significantly more likely to have experienced an overdose and showed a significantly higher score on several EuropASI, SCL-90-R and MCMI-II variables. According to these results, patients with violence control problems present with both a more severe addiction and several comorbid problems. The implications of these results for further research and clinical practice are discussed.

Aggression and psychopharmacological treatments in major psychosis and personality disorders during hospitalisation

BACKGROUND

A number of large-scale studies have shown that there is a relationship between many psychiatric disorders and aggression or violence. As no medication is currently approved for the treatment of aggression, pharmacotherapy (often involving drug combinations) is used on a trial-and-error basis with various degrees of response.

METHOD

The study involved 244 in-patients aged 19-83 years (mean 41.9 ± 11.3 SD). The Modified Overt Aggression Scale (MOAS) was used to assess any aggressive or violent behaviors occurring in the week before admission and upon discharge. Psychopathology was assessed using the Brief Psychiatric Rating Scales (BPRS).

RESULTS

All of the patients showed a significant improvement (p<0.001) in mean weighted total MOAS scores at the end of the study, with no significant differences between the various drugs or combination therapies. The patients who received combination treatments including antidepressants showed a worsening in the weighted total MOAS score (18.46% ± 114.31% SD); the patients who did not receive antidepressants had an improvement (13.61% ± 257.36% SD) (p=0.0069).

CONCLUSIONS

Multivariate testing of the variables age, gender, substance/alcohol abuse, the duration of hospitalisation, the administration of mood stabilisers, and the use of typical or atipical antipsychotics showed that the severity of the psychopathological picture correlated significantly with the presence of violence, whereas the effect of combined antidepressant treatment on violent behavior was only relative.

Predictors of compulsory admission in schizophrenia-spectrum patients: excitement, insight, emotion perception

PURPOSE

We explored socio-demographic and clinical variables associated with compulsory admissions (CA) compared with voluntary admissions in schizophrenia-spectrum patients; moreover, we investigated the ability of excitement, emotion perception, and lack of insight to predict CA.

METHODS

119 consecutive schizophrenia-spectrum patients admitted to the Servizio Psichiatrico di Diagnosi e Cura (SPDC = PES = psychiatric emergency service) of the Department of Neuroscience and Mental Health-San Giovanni Battista Hospital of Turin in the period between December 2007 and December 2009 were enrolled in the study. A backward stepwise logistic regression was used to test factors contributing to CA.

RESULTS

CA rate in our sample was 28.5%. Previous CAs, drop-out, severity of illness, positive symptoms, excitement, emotion perception, and insight were significantly different in CA patients compared to voluntary ones. After backward selection of variables, three variables predicted CA in our sample: excitement, impaired emotion perception and lesser insight. Finally, the effect of excitement on CA status seemed partially mediated by emotion perception, the prediction model accounting for 53.8% of the variance of CA status. Conversely, insight seemed not to be a mediator of excitement on CA.

IMPLICATIONS

Understanding CA patterns in special populations represents a first step towards improving clinical decision-making and developing appropriate interventions and service-provision.

Patients' own statements of their future risk for violent and self-harm behaviour: a prospective inpatient and post-discharge follow-up study in an acute psychiatric unit

Recently patients' responsibility for and ownership of their own treatment have been emphasised. A literature search on patients'' structured self-reported assessment of future risk of violent, suicidal or self mutilating behaviour failed to disclose any published empirical research. The present prospective naturalistic study comprised all involuntary and voluntary acutely admitted patients (n=489) to a psychiatric hospital during one year. Patients' self-reported risks of violence and self-harm at admission and at discharge were compared with episodes recorded during hospital stay and 3 months post-discharge. Patients' predictions were significant concerning violent, suicidal and self-injurious behaviour, with AUC values of 0.73 (95%CI=0.61-0.85), 0.92 (95%CI=0.88-0.96) and 0.82 (95%CI=0.67-0.98) for hospital stay, and 0.67 (95%CI=0.58-0.76), 0.63 (95%CI=0.55-0.72) and 0.66 (95%CI=0.57-0.76) after 3 months, respectively. Moderate or higher risk predictions remained significant in multivariate analysis, and risk of violence even after gender stratification. Self-harm predictions were significant for women. Moderate or higher risk scores remained significant predictors of violence one year post-discharge. Controlling for readmissions the results remained the same. Low sensitivity limits the clinical value, but relatively high positive predictive values might be clinically important. Still future research is recommended to explore if self prediction is a valid adjuvant method to established risk assessment procedures.

Hostility of drug-free patients with schizophrenia and n-3 polyunsaturated fatty acid levels in red blood cells

Many reports suggest that n-3 polyunsaturated fatty acids (PUFAs) influence the symptoms of psychiatric disorders. Moreover, it has also been reported that n-3 PUFAs control aggression and hostility. Acute symptoms of schizophrenia such as aggression can be a formidable clinical problem resulting in hospitalization. However, few investigations have determined the relationships between acute symptoms of drug-free schizophrenia and n-3 PUFAs. We recruited 75 inpatients with acute drug-free schizophrenia admitted to Chiba Psychiatric Medical Center, an emergency psychiatric hospital. Blood was sampled immediately after admission. The red blood cell (RBC) fatty acid composition and hostility score of Positive and Negative Syndrome Scale (PANSS) scores were measured. Multiple regression analysis showed that the concentrations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and the ratio of EPA/arachidonic acid (AA) in RBC showed significant negative correlations with the hostility score of PANSS scores after adjustment for age and sex. AA, on the other hand, showed significant positive correlations. The tissue n-3 PUFA and n-6 PUFA levels were negatively and positively associated with the hostility score of PANSS scores, respectively, suggesting possible effects of PUFA levels on hostile behavior in patients with schizophrenia.

Impulsivity in mania

Impulsivity, a breakdown in the balance between initiation and screening of action that leads to reactions to stimuli without adequate reflection or regard for consequences, is a core feature of bipolar disorder and is prominent in manic episodes. Catecholaminergic function is related to impulsivity and mania. Manic individuals have abnormal dopaminergic reactions to reward and abnormal responses in the ventral prefrontal cortex that are consistent with impulsive behavior. Impulsivity in mania is pervasive, encompassing deficits in attention and behavioral inhibition. Impulsivity is increased with severe course of illness (eg, frequent episodes, substance use disorders, and suicide attempts). In mixed states, mania-associated impulsivity combines with depressive symptoms to increase the risk of suicide. Clinical management of impulsivity in mania involves addressing interpersonal distortions inherent in mania; reducing overstimulation; alertness to medical-, trauma-, or substance-related problems; and prompt pharmacologic treatment. Manic episodes must be viewed in the context of the life course of bipolar disorder.

The reliability and validity of the Chinese version of the Modified Overt Aggression Scale

Objective. Instruments to assess aggressive behaviors in the psychiatric ward are crucial for monitoring risky behaviors. The purpose of this study was to assess the validity and reliability of the Chinese version of the Modified Overt Aggression Scale (MOAS). Methods. We translated the English version of MOAS into Chinese. We interviewed and trained two volunteers to act as agitated patients in the seclusion room. One senior psychiatrist, experienced in using the MOAS, directed scenarios of different aggressive intensity and established the standard scores. The validity was assessed by comparing the other raters' scores with those of the director's. Inter-rater reliability was also assessed. Results. Inter-rater reliability, based on Intra-class correlation coefficient (ICC=0.94, P<0.001) and Kendall's W coefficient of concordance (W=0.83, P= 0.001), was high. The validity was assessed by the Mann-Whitney test. The results showed that the raters adequately differentiated (z=- 2.89, P= 0.002) between the above-average and below-average scores of the MOAS. Conclusion. The Chinese version of the MOAS has modest psychometric properties. The model, which used trained volunteers acting as patients and compared their scores with those of the director, may be used in further studies for developing psychometric instruments to assess abrupt behaviors.
