Background: Serious violent acts (e.g. physical violence, robbery, sexual aggression and death threats) are among the most visible and notable examples of workplace violence. Although women are commonly found to be at higher risk for post-traumatic reactions following workplace violence, little is known as regards sex differences concerning the types of post-traumatic reactions and their predictors. Objective: This study aimed to describe sex differences in the post-traumatic reactions of serious violent acts and the predictors of such reactions...

Psychotic disorders often have been linked with violence. However, studies have shown that people with a psychotic disorder are more often victim than perpetrator of violence. The objective of this meta-analysis was to review prevalence rates for different types of victimization and to identify risk factors associated with victimization. Based on a search in MEDLINE, PsycINFO, and Web of Science, 27 studies were found with samples consisting of adults with a psychotic disorder and possible victimization occurring during adulthood and data on "violent victimization," "sexual victimization," "non-violent victimization," and/or "victimization not otherwise specified...

Contemporary research in the drugs field has demonstrated a number of gender differences in patterns and experiences of substance use, and the design and provision of gender-responsive interventions has been identified as an important policy issue. Consequently, whether and how domestic drug policies attend to women and gender issues is an important question for investigation. This article presents a policy audit and critical analysis of Australian national and state and territory policy documents. It identifies and discusses two key styles of problematisation of women's drug use in policy: 1) drug use and its effect on women's reproductive role (including a focus on pregnant women and women who are mothers), and 2) drug use and its relationship to women's vulnerability to harm (including violent and sexual victimisation, trauma, and mental health issues)...

Forensic experts often have to assess injury and fatality risks in the context of violent blunt force trauma. Maximum striking velocities in one- and two-handed strikes with a rod-like implement can be of particular interest. Current literature lacks studies addressing this problem. The purpose of this study was therefore to measure and analyse maximum striking velocities in one-handed and two-handed strikes in female and male volunteers. We hypothesised higher striking velocities in two-handed strikes compared to one-handed strikes...

OBJECTIVES: San Juan ante Portam Latinam is one of a small number of European Neolithic sites meeting many of the archaeological criteria expected for a mass grave, and furthermore presents evidence for violent conflict. This study aims to differentiate between what is potentially a single episode of deposition, versus deposition over some centuries, or, alternatively, that resulting from a combination of catastrophic and attritional mortality. The criteria developed are intended to have wider applicability to other such proposed events...

OBJECTIVE: People affected by schizophrenia spectrum disorders are at a higher risk of offending violently. This study aims to investigate risk factors in relation to the peri-diagnostic period and possible predictors of post-diagnostic violence of people diagnosed for the first time in the public mental health system. METHODS: The study compared various risk factors for post-diagnostic violence in patients ( n = 1453) diagnosed with a schizophrenia spectrum disorder...

PURPOSE OF REVIEW: The contribution of people with psychosis to homicide statistics is small, but there is a statistically significantly higher rate of homicide among them than in the general population. Legal authorities and the wider public call for more information. Our aim was a narrative synthesis of empirical literature generated by systematic searches for the five complete years 2013-2017. RECENT FINDINGS: One article showed that people with psychosis are five times more likely to be homicide victims than those without, but focus remains on perpetrators...

Introduction: Hospital emergency departments (EDs) around the country are being challenged by an ever-increasing volume of patients seeking psychiatric services. This manuscript describes a study performed to identify internal and external factors contributing to repeated psychiatric patient admissions to the hospital main ED. Methods: Data from ED visits of patients who were admitted to the Parkland Memorial Hospital ED (the community hospital for Dallas County, TX, USA) with a psychiatric complaint more than once within a 30-day period were evaluated (n=202)...

It is a widespread concern that violent video games promote aggression, reduce pro-social behaviour, increase impulsivity and interfere with cognition as well as mood in its players. Previous experimental studies have focussed on short-term effects of violent video gameplay on aggression, yet there are reasons to believe that these effects are mostly the result of priming. In contrast, the present study is the first to investigate the effects of long-term violent video gameplay using a large battery of tests spanning questionnaires, behavioural measures of aggression, sexist attitudes, empathy and interpersonal competencies, impulsivity-related constructs (such as sensation seeking, boredom proneness, risk taking, delay discounting), mental health (depressivity, anxiety) as well as executive control functions, before and after 2 months of gameplay...

Research has consistently demonstrated that people diagnosed with serious mental illness (SMI) are at increased risk for violent ideation and behavior (VIB) and that this is especially the case for SMI patients with comorbid substance use disorders (SUD). Despite this, what is still largely unknown is the relative prevalence of VIB across diagnostic categories, whether the rates of VIB in SMI groups exceed the rates observed in people with SUD only, and which demographic factors increase the likelihood of VIB under different circumstances for people with SMI...

BACKGROUND AND AIM: Alcohol is associated with violent behavior, although little is known regarding to what extent alcohol increases homicide risk. We aimed to estimate risks of homicide offending and victimization conferred by the presence of ethanol in blood by using toxicological data from homicide victims and offenders and from controls who had died in vehicle-related accidents. METHODS: From nationwide governmental registries and databases, forensic-toxicological results were retrieved for victims (n = 200) and offenders (n = 105) of homicides committed during the years 2007-2009 and individuals killed in vehicle-related accidents (n = 1629) during the years 2006-2014...

OBJECTIVES: With our study we aimed to (1) understand what factors uniquely conferred risk for physical and sexual forms of teen dating violence (TDV) perpetration and (2) create a screening algorithm to quantify perpetration risk on the basis of these factors. METHODS: A total of 1031 diverse public high school students living in Southeast Texas participated in our study (56% female; 29% African American, 28% white, and 31% Hispanic). Self-report measures concerning TDV and associated risk factors were completed annually for 6 years...

BACKGROUND: Since 2015, Europe has been facing an unprecedented arrival of refugees and migrants: more than one million people entered via land and sea routes. During their travels, refugees and migrants often face harsh conditions, forced detention, and violence in transit countries. However, there is a lack of epidemiological quantitative evidence on their experiences and the mental health problems they face during their displacement. We aimed to document the types of violence experienced by migrants and refugees during their journey and while settled in Greece, and to measure the prevalence of anxiety disorders and access to legal information and procedures...

Research has established that childhood maltreatment experiences are associated with negative outcomes in adolescence, including violent and antisocial behavior (Chapple et al., 2005). Neglect is the most prevalent form of childhood maltreatment (U.S. DHHS, 2012), the consequences of which require further investigation. This study used archival data to explore whether childhood physical neglect increased the likelihood of violent behavior in a random sample of 85 males between the ages of 12-19 held at a long-term detention facility in the Northeastern United States...

Many things can harm children's well-being. Among them, exposure to parental violence makes children vulnerable and often leads to aggression and/or depression. However, not all children who have suffered parental violence show aggressive behavior or depressive mood. Social capital, defined as resources accruing from interpersonal relationships, was proposed to significantly mediate the relationships among adverse experiences and their negative impacts. In previous studies, social capital accrued from parents played a positive role for children in violent situations, but children exposed to parental violence need alternative sources of social capital...

Heightened group identification motivates individuals to perpetrate violence, but can perpetrating violence-in and of itself-increase identification with violent groups? I test this idea using archival surveys of ex-combatants. In Liberia, where many combatants joined their violent group willingly, the data show a positive association between perpetrating violence and identification with one's violent group (Study 1). These results hold even when controlling for potentially confounding variables such as being abducted into the group versus joining willingly, length of time in the group, and personally experiencing violence...

Our research brings to light features of the social world that impact moral judgments and how they do so. The moral vignette data presented were collected in rural and urban Croatian communities that were involved to varying degrees in the Croatian Homeland War. We argue that rapid shifts in moral accommodations during periods of violent social strife can be explained by considering the role that coordination and social agents' ability to reconfigure their social network (i.e., relational mobility) play in moral reasoning...

The polytrauma clinical triad refers to the co-occurrence of chronic pain, traumatic brain injury (TBI), and posttraumatic stress disorder (PTSD). Despite research implicating dyadic relationships between these conditions and adverse outcomes, scant research has examined the polytrauma clinical triad's relation to suicide or violence. The present cross-sectional study was designed to examine whether this complex clinical presentation increases risk of suicidal ideation and violent impulses after accounting for other established risk factors...

This study addresses the epidemiology of risk factors and personality traits in adolescents of 16 and 17 years of age, charged with homicide, with a focus on analyzing psychic functioning, socio-demographic variables and family constitution. This is a longitudinal, retrospective and inferential study of the psychiatric assessments of several subjects who were interviewed in the Family Courts of the province of Mendoza. The hypothesis states that adolescents who have violent behavior, impulsivity and diffculty in complying with rules, do so as a result of having been victims of violence in an inadequate family environment...
