The aim of the study was to explore the predictive validity of the Suicidal Scale of the Mini-International Neuropsychiatric Interview as a screen for suicidal behavior and non-suicidal self-injury following discharge from an acute psychiatric ward. Using a prospective, naturalistic design, the patients were screened with the Suicidal Scale when discharged (n = 307). At 12 months post-discharge, the Suicidal Scale was a significant predictor of suicidal behavior (n = 48) and suicidal behavior+non-suicidal self-injury (n = 49) but not for non-suicidal self-injury (n = 15). For patients without any known previous suicide attempts (n = 180), the Suicidal Scale was a significant predictor of suicidal behavior (n = 21) and suicidal behavior+non-suicidal self-injury (n = 11). Further research is needed to determine the overall utility of the routine screening of self-harm.

BACKGROUND Current violence risk assessment instruments are time-consuming and mainly developed for forensic psychiatry. A paucity of violence screens for acute psychiatry instigated the development and validation of the V-RISK-10. The aim of this prospective naturalistic study was to test the predictive validity of the V-RISK-10 as a screen of violence risk after discharge from two acute psychiatric wards. METHODS Patients were screened with V-RISK-10 before discharge, and incidents of violence were recorded 3, 6, 9 and 12 months after discharge. A total of 381 of the 1017 patients that were screened completed the follow up. RESULTS The ROC-AUC values for any violent behaviour were 0.80 and 0.75 (p<0.001) for the 3 and 12 months follow-up periods, respectively, and significant for both genders. The most accurate risk estimates were obtained for severe violence. For persons without a known history of violence prior to the screening, AUCs were 0.74 (p=0.004) and 0.68 (p=0.002). CONCLUSIONS Results indicate that the V-RISK-10 is a valid and clinically useful screen for violence risk after discharge from acute psychiatry, and even significant for patients without a known previous history of violence.

Cross-sectional studies have reported an association between lipids and serotonin levels and aggression, but a literature search revealed a paucity of prospective studies. Subjects of the present naturalistic study were 254 of all (489) involuntary and voluntary acutely admitted patients to a psychiatric hospital during 1year. Serum lipids and platelet serotonin at admission were prospectively compared with recorded intra-institutional and 1-year post-discharge violence and self-harm. Total cholesterol had a significant negative relationship to inpatient suicidal behaviour and inpatient violent behaviour and to 3-month post-discharge violent behaviour. Triglycerides were a significant marker of inpatient self-mutilation and of self-mutilation in combination with suicidal behaviour at 3 and 12 months of follow-up. High-density lipoprotein (HDL) had a significant negative relationship to violence at 12-months, and to repeated violence in seven patients with two or more admissions. The post-discharge relationships between total cholesterol and violence and between triglycerides and self-harm remained significant even when controlling for other possible explanatory variables in a multivariate model. Results did not change after controlling for current medication at admission. There was no association between platelet serotonin and violence or self-harm. Future research may examine if lipid measurements add incremental validity to established clinical risk assessment procedures of violent and self-harm behaviour.

BackgroundThe objective was to examine various aspects of narcissism in patients admitted to acute psychiatric wards and to compare their level of narcissism to that of an age- and gender-matched sample from the general population (NORM).MethodsThis cross-sectional study interviewed 186 eligible acute psychiatric patients with the Brief Psychiatric Rating Scale (BPRS) and the Global Assessment of Functioning (GAF). The patients filled in the Narcissistic Personality Inventory-21 item version (NPI-21), The Hospital Anxiety and Depression Scale (HADS) and the Rosenberg Self-Esteem Scale. High and low narcissism was defined by the median of the total NPI-21 score. An age- and gender-matched control sample from the general population also scored the NPI-21 (NORM).ResultsBeing male, involuntary admitted, having diagnosis of schizophrenia, higher self-esteem, and severe violence were significantly associated with high narcissism, and so were also low levels of suicidality, depression, anxiety and GAF scores. Severe violence and high self-esteem were significantly associated with high narcissism in multivariable analyses. The NPI-21 and its subscales showed test-retest correlations ≥0.83, while the BPRS and the HADS showed lower correlations, confirming the trait character of the NPI-21. Depression and suicidality were negatively associated with the NPI-21 total score and all its subscales, while positive association was observed with grandiosity. No significant differences were observed between patients and NORM on the NPI-21 total score or any of the NPI subscales.ConclusionNarcissism in the psychiatric patients was significantly associated with violence, suicidality and other symptoms relevant for management and treatment planning. Due to its trait character, use of the NPI-21 in acute psychiatric patients can give important clinical information. The similar level of narcissism found in patients and NORM is in need of further examination.

The Narcissistic Personality Inventory (NPI) is commonly used in empirical studies of narcissism. Few population-based studies have been published. Our aim was to do a confirmatory factor analysis (CFA) of the NPI 29 item version with a four-factor structure, in two population-based samples and in a patient sample, and present normative population-based data. The NPI-29 was filled in by 324 respondents from the Norwegian population, 231 from the Swedish population and 167 Norwegian psychiatric patients. The four-factor structure of the NPI-29 with Leadership/Power, Exhibitionism/Self-admiration, Superiority/Arrogance and Uniqueness/Entitlement was reproduced in these samples. The CFA models showed good fit indices in all samples. Mean scores on the NPI-29 and four subscales hardly differed between the samples. For the NPI-29 total score and factors, few significant differences were observed. CFA of the samples supported the factor structure of the NPI-29 formerly identified by principal component analysis of the Swedish population sample.

ABSTRACT In this one-year prospective, naturalistic study in an acute psychiatric facility, we explored gender differences between 230 men and 284 women regarding the predictive validity of the Violence risk screening-10 (V-RISK-10). Hospital staff recorded violent incidents during hospital stays (range 1–176 days; median: 5.5 days) resulting in 50 men (22%) and 30 women (11%) being recorded for violence. The predictive validity was significant for both genders, with ROC-AUCs of .79 for males and .80 for females. Scoring at cut-off or beyond indicated a two-fold increased risk of becoming violent for men and a three-fold risk for women. A lower score indicated a five-fold decrease in risk for both genders. Estimates of explained variance for the prediction model were higher for men. Findings indicate gender differences for risk factors of violence and highlight the need of further research on this issue.

This prospective observational study included 345 (70%) of 489 patients discharged from an emergency psychiatric hospital during one year. Episodes of offending and victimization were recorded during first year after discharge. Forty-eight persons (14%) committed violent offenses only, 27 persons (8%) were violence victims only, and 42 persons (12%) were both offenders and victims. Significant differences in demographic and clinical variables were found between the three groups. The results pointed to two distinct groups of victims: one group with a robust offender-victim overlap and another group without offender-victim overlap. The latter group was difficult to distinguish from other discharged patients.

Several studies indicate an association between low levels of serum cholesterol and aggressive behaviour, but prospective studies are scarce. In this naturalistic prospective inpatient and post-discharge study from an acute psychiatric ward, we investigated total cholesterol (TC) and high-density lipoprotein (HDL) as risk markers of violence. From March 21, 2012, to March 20, 2013, 158 men and 204 women were included. TC and HDL were measured at admission. Violence was recorded during hospital stay and for the first 3 months post-discharge. Univariate and multivariate binary logistic regression were used to estimate associations between low TC and low HDL and violence. Results showed that HDL level was significantly inversely associated with violence during hospital stay for all patients. For men, but not for women, HDL level was significantly inversely associated with violence the first 3 months post-discharge. Results indicate that low HDL is a risk marker for inpatient and post-discharge violence in acute psychiatry and also suggest gender differences in HDL as a risk marker for violence.

The first Norwegian tools designed to assess the violence risk of the mentally ill were developed in the late 1980s, though the first national guidelines for both violence and suicide risk assessment were not published until two decades later in 2007. This article reviews the history of the field of forensic risk assessment in Norway from its humble beginnings to the present day. First an overview is provided of the history of forensic psychiatry and the criminal justice system. The main scope, however, is to discuss current research on and practice of risk assessment of violence in Norway, with an emphasis on the development and use of Norwegian risk assessment tools and methods. Particular attention is paid to instruments that follow the structured professional judgment model of risk assessment, as actuarial tools are rarely researched and not routinely implemented in clinical practice in Norway. Finally, a brief analysis is provided of some controversies concerning risk assessment in the expert witness reports on Anders Behring Breivik, who murdered 77 persons in 2011.

The Violence Risk Screening - Police Version (V-RISK-POL) is a seven-item screening tool for use at police stations by police officers and law enforcement officials to assist in the process of decision making regarding release, restrictive measures or arrest for apprehended individuals where the risk of future violence must be considered. The screen is based on the V-RISK-10, originally developed for emergency psychiatry. We examined psychometric properties and the prospective predictive validity of future violent convictions for the V-RISK-POL in a sample of 111 persons arrested for suspicion of violent crimes. Seventeen persons were convicted for a new violent crime committed during the 24-40months follow-up. The V-RISK-POL demonstrated good internal consistency; Cronbachs alpha=0.81 (95% CI=0.75-0.86) and moderate predictive validity; the area under the curve of the receiving operator characteristics (AUC)=0.753 (95% CI=0.644-0.843). Further research on larger and more heterogeneous samples is necessary to examine whether the screen may be useful in the police context.
