Video game violence: A review of the empirical literature

The popularity of video games, especially violent video games, has reached phenomenal proportions. The theoretical line of reasoning that hypothesizes a causal relationship between violent video-game play and aggression draws on the very large literature on media violence effects. Additionally, there are theoretical reasons to believe that video game effects should be stronger than movie or television violence effects. This paper outlines what is known about the relationship between violent video-game playing and aggression. The available literature on virtual reality effects on aggression is discussed as well. The preponderance of the evidence from the existing literature suggests that exposure to video-game violence increases aggressive behavior and other aggression-related phenomena. However, the paucity of empirical data, coupled with a variety of methodological problems and inconsistencies in these data, clearly demonstrate the need for additional research.     

Substance abuse and violence: A review of the literature

Most alcohol and drug use occurs among persons who are not violent. However, alcohol and, to a lesser extent, illicit drugs are present in both offenders and victims in many violent events. The links between psychoactive substances and violence involve broad social and economic forces, the settings in which people obtain and consume the substance, and the biological processes that underlie all human behavior. In the case of alcohol, evidence from laboratory and empirical studies support the possibility of a causal role in violent behavior. Similarly, the psychopharmacodynamics of stimulants, such as amphetamines and cocaine, also suggest that these substances could play a contributing role in violent behavior. On the other hand, most real-world studies indicate that this relationship is exceedingly complex and moderated by a host of factors in the individual and the environment. In addition to psychopharmacological effects, substance use may lead to violence through social processes such as drug distribution systems (systemic violence) and violence used to obtain drugs or money for drugs (economic compulsive violence).     

Reducing psychopathic violence: A review of the treatment literature

Psychopathy reflects a pathological form of personality that predisposes individuals to risk for perpetration of chronic and severe violence across their lifespan. The violence attributable to psychopathic persons constitutes a substantial portion of the societal burden to the public health and criminal justice systems and thus necessitates significant attention by prevention experts. However, there is a relatively nascent literature that has examined psychopathic persons' response to treatment, especially considering violence as an outcome. Nevertheless, there have been repeated averments about the amenability (or lack thereof) of psychopathy to treatment. In the present paper, we attempt to provide a comprehensive review of studies assessing the relation of psychopathy to violence outcomes following intervention. Our review of studies suggests there is reason to suspect that specific and tailored interventions which take into consideration psychopathic persons' unique patterns of behavioral conditioning and predispositions may have the potential to reduce violence. However, equally important, certain interventions may potentially exacerbate these persons' violent behavior. The nature of the outcomes is likely highly dependent on the specific components of the intervention itself. We conclude that future research should increase methodological rigor by striving to include treatment control groups and increasing the transparency of the implemented interventions.     

Issues in the dating violence research: A review of the literature

Since the 1980s, a growing research literature on violence in dating relationships has emerged, raising considerable concern about the extent of violence occurring in campus dating relationships across the United States. Such research has extended the knowledge base not only about the incidence and types of violence occurring but also about consequences, contributing factors, and gender differences. However, there are a number of important research issues in the literature that require clarification and/or research replication. This review identifies and addresses these issues in three sections. The first section of the review examines methodological issues, which include definition, violence rates, and sampling. The second section addresses gender and violence, in particular the relationship of gender to perpetration, victimization, and attitudes. The final section examines the issue of theory and focuses on the relative support for social learning and feminist theories, the two major theories in the dating violence literature. The review concludes with a series of recommendations for further dating violence research, based on identified gaps in the current literature.     

Intimate partner violence in military couples: A review of the literature

IntroductionIntimate partner violence (IPV) is a serious public health concern that has not received an immense amount of attention in the military community. It is well documented in military literature that rates of IPV across US military populations range from 13.5% to 58%, with considerably lower rates obtained among samples not selected on the basis of psychopathology (Marshall, Panuzio, & Taft, 2005). The main objectives are to address the this gap in literature concerning the definitions of violence used, prevalence of IPV in military intimate relationships, the nature and patterns of violence, risk factors, and theories that may help to provide a better understanding of the violence attached to this unique population.Methods and theoryCivilian and military communities are urged to work towards using common definitions and practices to facilitate comparison of rates among the populations. Furthermore, methodological tools should move towards using more multi-method and longitudinal designs, more theoretical model applications and more diverse sample selection as strategies to further our understanding of the structure and inner workings of IPV in military couples.Conclusion and recommendationsMore exhaustive research, especially in Canada, including consistent definitions and methodology needs to be conducted. Also, future research needs to address the gap in the literature regarding theory application, risk factors associated with this phenomenon, and prevention methods.     

The aftermath of workplace violence among healthcare workers: A systematic literature review of the consequences

Workplace violence is an important health and safety issue. Healthcare workers are particularly at risk of experiencing workplace violence. Despite the research that was conducted in this domain, little is known about the consequences of being a victim of workplace violence, specifically in the healthcare sector. Therefore, this article aims to review the literature regarding the consequences of exposure to workplace violence in the healthcare sector. Sixty-eight studies were included in the review and they were evaluated according to 12 criteria recommended for systematic reviews. The studies identified seven categories of consequences of workplace violence: (1) physical, (2) psychological, (3) emotional, (4) work functioning, (5) relationship with patients/quality of care, (6) social/general, and (7) financial. Psychological (e.g., posttraumatic stress, depression) and emotional (e.g., anger, fear) consequences and impact on work functioning (e.g., sick leave, job satisfaction) were the most frequent and important effects of workplace violence. In conclusion, this paper recommends further research, particularly longitudinal studies, in order to better grasp the direct and indirect effects of workplace violence.     

A review of the literature on marijuana and interpersonal violence

Marijuana use and interpersonal violence are major public health problems. The present review examines the available empirical and theoretical literature on the relationship between marijuana and violence, including past theoretical models, the link between marijuana use and interpersonal violence (including intimate partner violence), and the relationship between marijuana withdrawal and violence. While results from laboratory-based studies are inconclusive, results of cross-sectional and longitudinal research provide support for an association between marijuana use/withdrawal and various types of violence. Given the lack of empirical support for existing models, a new biopsychosocial model of the marijuana–violence relationship is proposed. Examining methods to test this model and application of current findings to treatment are discussed.     

Individual characteristics related to prison violence: A critical review of the literature

At the end of 2010, prisons in the United States incarcerated over 1,605,127 inmates, yielding an imprisonment rate of 497 per 100,000 residents (Guerino, Harrison, & Sabol, 2011). Approximately 15.6% of correctional officers have been the victim of an inmate assault (Duhart, 2001) and 21% of inmates reported being victims of violence in prison (Wolff, Blitz, Shi, Siegel, & Bachman, 2007). However, which inmates are more likely to perpetuate these violent acts while incarcerated? The present paper critically reviews the empirical literature on the relation between individual characteristics of inmates and prison violence. Variables are divided into three general categories: demographic, criminal history, and psychological variables. From over 500 studies, a representative sample of 20 studies from 1990 to 2011 was reviewed based on specified inclusion criteria, such as adult males incarcerated in English-speaking countries. Although there are some discrepant findings, a general conclusion can be reached regarding most variables. These characteristics are compiled into a prototype of an inmate at “high” risk and an inmate at “low” risk for prison violence. Methodological limitations of the research are presented, as well as suggestions for future research directions.     

Primary and secondary prevention programs for dating violence: A review of the literature

Recent research has consistently demonstrated that a significant proportion of dating relationships are characterized by violent interactions. Aggression that occurs in the context of dating relationships is associated with a variety of deleterious effects in the context of the current relationship, and provides a potential trajectory to more severe forms of violence in later relationships. These data have led researchers and practitioners to develop and implement programs designed to prevent such violent dating behaviors. This comprehensive review examines the literature on primary and secondary prevention programs for dating violence, with emphases on methodological and theoretical issues. Ubiquitous limitations of the current research are identified, as well as future directions and implications for researchers and practitioners in the field.     

Dating violence in the United Kingdom: A preliminary study

A small-scale study of “dating violence” in a sample of UK college students is described. Methodology involved the rating-scale used in existing US studies, with the addition of an assessment of inter-respondent reliability, which was found to be high. A high incidence of some form of violence was found, with women showing higher levels than men, thus replicating previous US findings based on victim reports. Violence in the present relationship was found to be unrelated to violence in past relationships.     

Risk and dynamics of violence in Asperger's syndrome: A systematic review of the literature

The main purpose of this article is to delineate findings from a review of the literature on the empirical basis for the existence of a relationship between Asperger's syndrome (AS) and violence risk. A second aim is to examine whether certain characteristics of the disorder may have a higher violence-triggering potential. Results of this review show that there are very few empirical studies that confirm a stable link between AS and violence. Only 11 studies involving 22 patients and 29 violent incidents met the criteria for inclusion in the review after the search of the literature. However, a qualitative analysis of the studies yielded some indications of possible patterns of dynamics of violence that may prove to be typical of persons with AS. A tentative comparison of AS and psychopathy indicated that there may be qualitative differences in the characteristics of violent behavior between the disorders. Suggestions for further research are presented.     

Psychological and criminological factors associated with desistance from violence: A review of the literature

Ample evidence exists that offenders eventually terminate their criminal careers, and this holds true for violent offenders. The causal mechanisms responsible for triggering and maintaining this process remain unclear; meaning that desistance from violence is poorly understood. This comprehensive review of the literature revealed that research in this area is hampered by definitional, operational, and measurement inconsistencies. Several of the conceptual frameworks used to explain desistance from delinquency have not been specifically applied in relation to violence. However, it was found that criminological enquiry suggests that informal social control (e.g., stable relationship and employment) play a role in desistance from violence and that theoretical frameworks which examine both internal and external change seem to show promise as an aid to understanding the desistance process. Psychological research has tended to focus on the role of risk and protective factors in relation to desistance but this, particularly protective factors, is currently under-researched. More knowledge needs to be assembled about how: (1) the mechanics of protective factors mitigate risk of future violence, and (2) how they play a role in the maintenance of violent free behaviors. Findings from criminology and psychology need to be expanded and integrated to extend our understanding of desistance from violence.     

Women who perpetrate intimate partner violence: A review of the literature with recommendations for treatment

The purpose of this article is to review the literature on women as perpetrators of violence in their intimate relationships (i.e., domestically violent women) and summarize the scant literature on intervention programs for these women. Particular attention is paid to the cultural influences that shape our conceptualization of “domestic violence” and the fact that empirical research suggests that domestic violence has been falsely framed as exclusively male initiated violence. The article concludes with a discussion of the similarities and differences between male and female domestic violence offenders and identifies areas where treatment for female offenders might be improved.     

Domestic violence and woman's reproductive health: a review of the literature

This paper outlines the current literature on the effect of violence on women's reproductive health. Domestic violence is considered worldwide to be a social health problem which particularly affects women. It is generally categorized in five groups as physical, sexual, verbal, economic, and emotional violence. Domestic violence against women also includes sterilization and abortion by force, forcing women to use contraceptives against their will, or withholding contraceptives from those who wish to use them, genital mutilation, killing female children, and choosing gender in the prenatal period. A woman infected with a sexually transmitted disease by her partner or husband, and having a partner or husband having sexual intercourse with another woman also falls within the sexual violence parameters. Domestic violence has significant effects on both the general and reproductive health of the women, and may cause serious complications and may end with death. The studies show that women exposed to violence have worse health conditions and benefit less from health services than others. Therefore, health care personnel have important responsibilities to define domestic violence and intervene when necessary. These personnel must also be educated in matters of domestic violence, effective policy and protocols must be put in place. And, very importantly, health personnel must be supported by their managers when they try to deal with matters relating to domestic violence.     

Evidence for publication bias in video game violence effects literature: A meta-analytic review

Violence in video games has come under increasing research attention over the past decade. Researchers in this area have suggested that violent video games may cause aggressive behavior among players. However, the state of the extant literature has not yet been examined for publication bias. The current meta-analysis is designed to correct for this oversight. Results indicated that publication bias does exist for experimental studies of aggressive behavior, as well as for non-experimental studies of aggressive behavior and aggressive thoughts. Research in other areas, including prosocial behavior and experimental studies of aggressive thoughts were less susceptible to publication bias. Moderator effects results also suggested that studies employing less standardized and reliable measures of aggression tended to produce larger effect sizes. Suggestions for future violent video game studies are provided.     

The functional anatomy of inspection time: a pilot fMRI study

Seven healthy subjects underwent functional magnetic resonance imaging (fMRI) of the brain while performing an inspection time task. Employing a block-type design, the task had three difficulty levels: a control condition, an easy (200 ms stimulus duration), and a more difficult (40 ms) discrimination. Based on group results, there were widespread significant areas of difference in brain activation and deactivation when pairwise comparisons were conducted among the three task conditions. When the difficult condition was compared with the easy condition, there was relative activation in areas of the following brain regions: cingulate gyrus and some frontal and parietal lobe areas. Areas within the following regions showed relative deactivation (greater blood oxygenation level-dependent, BOLD, signal in the easy condition): frontal, temporal, and parietal lobe. There were overlaps between these areas and those found to be active while performing higher cognitive tasks in other functional brain imaging studies. These pilot data encourage future studies of the functional anatomy of inspection time and its relevance to psychometric intelligence.

The study of sequence learning in individuals with schizophrenia: A critical review of the literature

The serial reaction time task (SRTT) has been used extensively to study implicit sequence learning. A number of studies have used the SRTT to examine sequence learning in schizophrenia patients. Despite these studies, it remains unclear whether sequence learning is impaired in patients, whether antipsychotic medications affect sequence learning, and what types of sequential information patients might have difficulty learning. Methodological limitations have made it difficult to obtain good answers to these questions. Methodological innovations from the general SRTT literature that have not yet been adopted in the schizophrenia literature could provide better answers.
