The nightlife setting is a risk context for violence involvement that ultimately may cause severe injuries and fatalities. Few studies have examined associations between alcohol and illicit substance use with physical violence involvement among nightlife patrons. The aim of the current study was to investigate the relative role of demographics and substance use characteristics for nightlife violence involvement among Norwegian nightlife patrons. A cross-sectional self-completion survey was conducted outside 12 licensed premises in Oslo (n = 1099, response rate = 76%) and each respondent's BAC level was measured by a breathalyzer and registered on the questionnaire...

Bullying is defined as repeated negative actions involving a power differential, and intention to harm. There is limited research on harmful intention as a definitional component. This study explored the role of the perpetrator's harmful intention and the target's perception of harmful intention. Some 209 students (M = 14.5 years; 66.5% female) and 447 parents (M = 46.4 years; 86.4% female) were randomly assigned in an online survey. Participants assessed the likelihood of bullying in five hypothetical scenarios (physical, verbal, rumor, exclusion, and cyber) across five intention conditions, that also involved repetition and a power differential...

We used couple-level data to predict physical acts of intimate partner violence (IPV) from self-reported negative emotions and social information-processing (SIP) abilities among 100 dating couples (n = 200; mean age = 21.45 years). Participants read a series of hypothetical conflict situation vignettes and responded to questionnaires to assess negative emotions and various facets of SIP including attributions for partner behavior, generation of response alternatives, and response selection. We conducted a series of negative binomial mixed-model regressions based on the actor-partner interdependence model (APIM; Kenny, Kashy, & Cook, 2006, Dyadic data analysis...

Rumination is associated with exacerbated angry mood. Angry moods may also trigger rumination. However, research has not empirically tested the bidirectional associations of state rumination and anger, as experience sampling methodology can do. We predicted that state anger and rumination would be bi-directionally associated, both concurrently and over time, even controlling for trait anger and rumination. In addition, because mindfulness is associated with rumination and anger at the bivariate level, we examined the effect of trait mindfulness on the bidirectional association between state rumination and anger...

Existing research has shown that child maltreatment is carried out by both mothers and fathers. There is also an extensive body of literature analyzing reasons for mothers' violent behavior. Among fathers, reasons are less well studied, resulting in the lack of a comprehensive picture of paternal child abuse. In this study, 20 child-, parent-, and family-related factors have been included in a combined analysis to assess which of these may pose a risk for fathers' severe violent behavior toward their children...

Physical aggression (PA) in the toddler years is common and developmentally normal, however, longitudinal research shows that frequent PA is highly stable and associated with long-term negative outcomes. Significant research has demonstrated the efficacy of parenting interventions for reducing externalizing behavior in children yet their typical length may overburden families, leading to low participation rates and high attrition rates. To increase the reach of parenting interventions and impact on the prevalence of externalizing behavior problems, brief interventions are needed...

Although the importance of peer bystanders in bullying has been recognized, there are few studies that examine the phenomenon in relation to Latané and Darley's (1970) classic Bystander Intervention Model, which states that there are five stages of bystander intervention: (i) notice the event; (ii) interpret the event as an emergency that requires assistance; (iii) accept responsibility for intervening; (iv) know how to intervene or provide help; and (v) implement intervention decisions. This study examined preliminary evidence of reliability and validity of the Bystander Intervention Model in Bullying (Nickerson, Aloe, Livingston, & Feeley, 2014), and the extent to which bullying role behavior (bullying, assisting, victimization, defending, and outsider behavior) and gender predicted each step of the model with a sample of 299 middle school students...

Exposure to different environments has been reported to change aggressive behavior, but previous research did not consider the underlying elements that caused such an effect. Based on previous work on environmental perception, we examined the role of environmental resource and security in altering aggression level. In three experiments, participants were exposed to environments that varied in resource (High vs. Low) and security (High vs. Low) levels, after which aggression was measured. The environments were presented through visual priming (Experiments 1-2) and a first-person gameplay (Experiment 3)...

This study examined the associations between teacher attunement to aggressive students and students' characteristics in a sample (n = 278) of youth in 5th-grade classrooms with the assumption that certain student characteristics may either prime or hinder teachers' attunement to aggressive students. Teacher attunement was measured as the agreement between teacher- and peer-nominations for students who start fights. Teachers rated their students on the following characteristics: academic competence, affiliation, popularity, internalizing behavior, and Olympian qualities...

Large numbers of British and American Reservists have been deployed to operations in Iraq and Afghanistan. Little is known about the impact of deployment and combat exposure on violent behavior in Reservists. The purpose of this study was to determine the prevalence of self-reported violent behavior among a representative sample of United Kingdom Reservists, the risk factors associated with violence and the impact of deployment and combat exposure on violence. This study used data from a large cohort study of randomly selected UK military personnel and included Reservists who were in service at the time of sampling (n = 1710)...

Malamuth's (1998) confluence model holds that the combination of hostile masculinity, impersonal sexuality, and the constellation of high dominance and low nurturance plays a crucial role in explaining men's sexual aggression against women. Most studies on the confluence model concentrate on hostile masculinity and impersonal sexuality rather than dominance and nurturance. Using a person-centered approach, we investigated whether sexual aggressive men could be better identified in a sample of 692 men when not only hostile masculinity and impersonal sexuality but also dominance and nurturance were used as indicators in a latent profile analysis...

Verbal and physical aggression begin early in life and steadily decline thereafter in normal development. As a result, elevated aggressive behavior in adolescence may signal atypical development and greater vulnerability for negative mental and health outcomes. Converging evidence suggests that brain disturbances in regions involved in impulse control, emotional regulation, and sensation seeking may contribute to heightened aggression. However, little is known regarding the neural mechanisms underlying subtypes of aggression (i...

The dual-hormone hypothesis suggests that testosterone is positively associated with status-seeking tendencies such as aggression and dominance, particularly in individuals with low levels of cortisol. Although recent research supports the dual-hormone hypothesis, its boundary conditions under which the dual-hormone interaction is likely to emerge are not clearly understood. In the present study (N = 153), the dual-hormone hypothesis was empirically tested in the context of an economic game that included a decision whether to dominate another individual...

Previous research has suggested an important role for the emotion of hatred in intergroup aggression. Recent theoretical and empirical work has strongly suggested that the combination of anger, contempt, and disgust (ANCODI) comprise the basic elements of hatred, and are the key emotions associated with intergroup aggression. No study, however, has provided evidence that these emotions cause hostile cognitions about specific groups. We report two studies that provide initial evidence. In both, participants were members of ideologically motivated groups and were primed with ANCODI...

An expanded self-report, vignette-based, questionnaire was developed to assess five components in a social emotional information processing model (SEIP: attribution, emotional response, response valuation, outcome expectancy, response efficacy, and response enactment), first in a population-based sample (n = 250) and, second in healthy control participants (n = 50) and in those with DSM-5 Intermittent Explosive Disorder (IED: n = 50). SEIP-Q vignettes depict, separately, both overtly aggressive and relationally aggressive as well as socially ambivalent scenarios...

Aggression in online contexts has received much attention over the last decade, yet there is a need for measures identifying the proximal psychological drivers of cyber-aggressive behavior. The purpose of this study was to present data on the newly developed Cyber-Aggression Typology Questionnaire (CATQ) designed to distinguish between four distinct types of cyber-aggression on dimensions of motivational valence and self-control. A sample 314 undergraduate students participated in the study. The results confirmed the predicted four-factor structure providing evidence for distinct and independent impulsive-aversive, controlled-aversive, impulsive-appetitive, and controlled-appetitive cyber-aggression types...

Vignette methodology can be a flexible and powerful way to examine individual differences in response to dangerous real-life scenarios. However, most studies underutilize the usefulness of such methodology by analyzing only one outcome, which limits the ability to track event-related changes (e.g., vacillation in risk perception). The current study was designed to illustrate the dynamic influence of risk perception on exit point from a date-rape vignette. Our primary goal was to provide an illustrative example of how to use latent variable models for vignette methodology, including latent growth curve modeling with piecewise slopes, as well as latent variable measurement models...

Previous work has demonstrated that both leaders and other individuals vary in dispositional levels of physical aggression, which are genetically influenced. Yet the importance of individual differences in aggression for attitudes toward foreign policy or context-laden moral choices, such as sacrificing the lives of some for the greater good of many, has yet to be fully explored. Given the global importance of such decisions, we undertook this exploration in a sample of 586 Australians, including 250 complete twin pairs...

We sought to identify relationship and individual psychological factors that related to four profiles of intimate partner violence (IPV) among pregnant adolescent couples: no IPV, male IPV victim only, female IPV victim only, mutual IPV, and how associations differ by sex. Using data from a longitudinal study of pregnant adolescents and partners (n = 291 couples), we used a multivariate profile analysis using multivariate analysis of covariance with between and within-subjects effects to compare IPV groups and sex on relationship and psychological factors...

The current study examined the moderating influence that different aspects of narcissism have on the relation between callous-unemotional (CU) traits and aggression in a sample of 720 adolescents (500 males), ages 16-19 enrolled in a 22-week residential program. Findings from the two studies revealed that psychopathy-linked narcissism as assessed by the Antisocial Process Screening Device (APSD; Frick & Hare, 2001; Antisocial process screening device. Toronto: Multi-Health Systems.) and vulnerable narcissism as assessed using the Pathological Narcissism Inventory (PNI; Pincus et al...
