Violent behavior of patients living in psychiatric residential facilities: a comparison of male patients with different violence histories.

People with severe mental disorders and a history of violence are often seen as a difficult-to-manage segment of the population. In addition, this group is usually characterized by a high risk of crime recidivism, and poor compliance with community and aftercare programs. To investigate a sample of male patients living in Residential Facilities (RFs) with a history of violent behavior against people and to compare their characteristics with those of never-violent residents; to analyze the associations between aggressive behaviors in the last two years and a history of previous violence; and, to assess the predictors of aggressive behaviors. This study is part of a prospective observational cohort study which involved 23 RFs in Northern Italy. A comprehensive set of sociodemographic, clinical, and treatment-related information was gathered, and standardized assessments were administered to each participant. Also a detailed assessment of aggressive behaviors in the past two years was carried out. The study involved 268 males: 81 violent and 187 never-violent. Compared to never-violent patients, violent patients were younger, with a higher proportion of personality disorders, and have displayed an increased number of aggressive behaviors in the last two years. The presence of a history of violent behavior in the past significantly increases the probability of committing aggressive acts in the future.

Clinical and neuropsychological features of violence in schizophrenia: A prospective cohort study.

The increased risk of violence in schizophrenia has been linked to several environmental, clinical and neuropsychological factors, including executive dysfunction. However, data about the nature of these effects are mixed and controversial. The main aim of this study was to investigate the relationship between clinical and neuropsychological factors with violence risk in patients with schizophrenia, taking into account current psychopathology and lifetime alcohol use. We compared a sample of patients living in Residential Facilities (RFs) with schizophrenia and a past history of interpersonal violence (vSZ, N=50) to patients with schizophrenia matched on age, gender and alcohol abuse/dependence but with no violence history (nvSZ, N=37). We then established the association between the clinical and neuropsychological factors that predicted violence over a 1year follow-up period. The results revealed that vSZ patients living in RFs were characterized by greater compulsory hospital admissions, higher anger and less negative symptoms as compared to nvSZ patients. vSZ patients performed better on executive and motor tasks than nvSZ; however, these differences appeared to be explained by the lower negative psychotic symptom in the vSZ group. Both groups were involved in episodes of violence during the follow-up period; among the two, the vSZ patients were more likely to be violent. Negative symptoms predicted less verbal aggression at 1year follow-up. Overall, these findings support a key role of negative rather than positive symptoms in driving violence risk among SZ patients living in RFs, in a manner that negative symptoms are linked to a lower risk of violence.

Monitoring and predicting the risk of violence in residential facilities. No difference between patients with history or with no history of violence.

BACKGROUND Most people with mental disorders are not violent. However, the lack of specific studies in this area and recent radical changes in Italy, including the closure of six Forensic Mental Hospitals, has prompted a more detailed investigation of patients with aggressive behaviour. AIMS To compare socio-demographic, clinical and treatment-related characteristics of long-term inpatients with a lifetime history of serious violence with controls; to identify predictors of verbal and physical aggressive behaviour during 1-year follow-up. METHODS In a prospective cohort study, patients living in Residential Facilities (RFs) with a lifetime history of serious violence were assessed with a large set of standardized instruments and compared to patients with no violent history. Patients were evaluated bi-monthly with MOAS in order to monitor any aggressive behaviour. RESULTS The sample included 139 inpatients, 82 violent and 57 control subjects; most patients were male. The bi-monthly monitoring during the 1-year follow-up did not show any statistically significant differences in aggressive behaviour rates between the two groups. The subscale explaining most of the MOAS total score was aggression against objects, although verbal aggression was the most common pattern. Furthermore, verbal aggression was significantly associated with aggression against objects and physical aggression. CONCLUSIONS Patients with a history of violence in RFs, where treatment and clinical supervision are available, do not show higher rates of aggressiveness compared to patients with no lifetime history of violence. Since verbal aggression is associated with more severe forms of aggression, prompt intervention is warranted to reduce the risk of escalation.

Personality, Schizophrenia, and Violence: A Longitudinal Study

The aims of this study were (a) to investigate the presence of clinically significant personality traits and personality disorders (PD) in patients living in residential facilities, with or without a history of violence (69 and 46, respectively); and (b) to investigate any associations between clinically significant personality traits and PDs, aggression, impulsivity, hostility, and violent behavior during a 1-year follow-up. The most frequent primary diagnoses were schizophrenia (58.3%) and PD (20.9%). Those with a history of violence demonstrated more antisocial and alcohol dependence features and lower depressive PD symptoms than the control group. Hostility levels, antisocial symptoms, and drug dependence, as well as a Structured Clinical Interview for DSM-IV Axis II diagnosis of PD, predicted aggressive and violent behavior during follow-up. The study confirms the relevance of assessing PDs both to evaluate the risk of violent behavior and to plan appropriate preventive and treatment intervention.

1044 – A prospective comparison between formerly and never violent patients living in psychiatric residential facilities

Introduction Persons with severe mental disorders and a history of violent offending are usually seen as a difficult-tomanage population: most have schizophrenia or severe affective disorders, while some suffer from severe personality disorders. Aims To investigate the sociodemographic, clinical, and treatment-related characteristics of a sample of patients living in RFs with a history of antisocial behaviour (‘violent’ group); to compare the characteristics of the ‘violent’ group with residents never violent; and to compare the rate of violent behaviour in the two groups over two years and to assess the likelihood of discharge in the two groups. Methods This is prospective observational cohort study involved 23 RFs of the St John of God Order in Northern Italy. The sample was divided into two groups: non-violent patients and ‘violent’ patients. The last included patients at last one time admitted in FMH or arrested for violent crimes or acted violent behaviors against people. For each inpatient was filled out a “Patient Schedule”: socio-demographic and clinical data were collected, including a specific session to assess aggressive behavior lifetime and in the last year. Results The study involved 403 patients: 89 ‘violents’ and 314 non-violent. ‘Violent’ group was mainly male, younger, with a prevalence of personality disorders. Coherently, in the group of ‘violent’ there were more people lifetime arrested and admitted to a FMH. Discussion There are some differences in the monitoring of violent behavior in the two years of assessment. We observed more threatening, slap, punch, inappropriate sexual harassment, etc. in the ‘violents’ group.

1036 – Characteristics of patients and factors associated to discharge from residential facilities: a prospective cohort study in italy

Introduction PERDOVE study is a prospective observational cohort study, which providing follow-up at one year, aims to investigate the socio-demographic and clinical characteristics of patients in in the 23 medium-long term RFs of the St John of God Order. Objectives (1) To describe the sociodemographic, clinical, and treatment-related characteristics of RF-patients during an index period in 2010; (2) to identify predictors and characteristics associated with discharge at 1-year follow-up; (3) to evaluate clinicians’ predictions about each patients likelihood of Home Discharge (HD). Methods All patients staying in September 2010 with a primary psychiatric diagnosis received a set of standardized assessment instruments, including a “Patient Schedule”, BPRS, HONOS, PSP, PHI, and SLOF. Detailed socio-demographic and clinical data were also collected. Logistic regression analyses were run to identify independent discharge predictors. Results The study involved 403 patients. 66,7% is male, mean age is 49 (±10). 70.7% is unmarried. The average duration of illness of these patients is 23 years. Primary diagnosis is represented by schizophrenic spectrum disorders (67.5%). At 1 year follow-up, 104 patients (25.8%) were discharged: 13.6% to home, 8.2% to other RFs, 2.2% to supported housing, and 1.5% to prison. Conclusions The main variables associated with a higher likelihood of being discharge to home were: to have an illness duration of less than 15 years and to have an available and effective social support in the last year. Lower severity of psychopathology, and higher working skills were also associated with a significantly higher likelihood to be discharged to home.

1039 – Predictors of quality of life in a sample of inpatients with schizophrenia in 23 residential facilities in northern italy

Introduction Many cross-sectional studies have explored the relationship between subjective QOL of people with schizophrenia and different socio-demographic characteristics, clinical and psychosocial factors. Only few studies tried to identify factors that influence the QOL of these patients using a longitudinal design. Objectives Aim of the present study was to determine influence of clinical factors, socio-demographic variables, spirituality and satisfaction with services on QOL, to identify clinical predictors associated with quality of life at one year follow-up. Material and methods Measures at baseline included: demographics, BPRS, PHI, RBANS, FPS, HoNOS, SWBS, VSSS, and the Italian version of the WHOQoL-Brief. Measures at follow up included: HONOS, BPRS, FPS, WHOQoL-Brief. Logistic regression models were adopted to evaluate the association between WHOQoL-Brief scores and patients sociodemographics, clinical characteristics, spirituality and services’ satisfaction. Results The study included 171 patients: 64% males; mean age 48.7 (sd=8.9) with primary diagnosis of schizophrenia. Different domains of QOL were predicted by different indicators at baseline. Younger age, more time spending doing nothing, lower BPRS, lower satisfaction with services were explanatory variables for low quality of life in psychological facet. Spirituality and religiousness were associated with Environmental domain and VSSS was associated to all QOL domains. Conclusions Rehabilitation plans for people with schizophrenia living in RFs should pay attention to mediators of change in subjective QOL such as level of activities, social support, spirituality and satisfaction with mental health services. In particular, anxiety and depressive symptoms remain as long-term outcomes of QOL at one year follow up.
