The I 3 Model: a metatheoretical framework for understanding aggression

Longitudinal Trajectories of Physical Teen Dating Perpetration and Trait Anger Expression: A Group-Based Trajectory Approach

Dating violence is often perpetrated among adolescents, which increases the efforts to better understand individual risk factors for preventive efforts. Although multiple forms (i.e., physical and psychological) often coexist, few studies have studied the chronicity and developmental classes of physical teen dating violence and examined whether subtypes of trait anger predict teen dating perpetration over time. Thus, the purpose of the current study is to investigate: (a) the developmental group-based patterns of physical teen dating violence; and (b) whether subtypes of trait anger expression predict association in these classes using the Bullying, Sexual, and Dating Violence Trajectories from Early to Late Adolescence in the Midwestern United States, 2007 to 2013 dataset. Group-based trajectory modeling results identified four classes of teen dating violence perpetration (e.g., Accelerating, Abstaining, Desisting, and High Chronic). Multinomial logistic regression results indicated that expressing anger outwardly was positively associated with Desisting and High Chronic patterns, but not Accelerating patterns. These results suggest that there are four classes of teen dating violence perpetration and underscore the effects of expression of trait anger as a risk factor of teen dating violence perpetration. Practical and theoretical implications are discussed.

Three roots of online toxicity: disembodiment, accountability, and disinhibition

Online communication is central to modern social life, yet it is often linked to toxic manifestations and reduced well-being. How and why online communication enables these toxic social effects remains unanswered. In this opinion, we propose three roots of online toxicity: disembodiment, limited accountability, and disinhibition. We suggest that virtual disembodiment results in a chain of psychological states primed for deleterious social interaction. Drawing from differences between face-to-face and online interactions, the framework highlights and addresses the fundamental problems that result in impaired communication between individuals and explicates its effects on social toxicity online.

Trends in child and adolescent assault and maltreatment following the re-introduction of the Banned Drinker Register in the Northern Territory, Australia

OBJECTIVE

In 2017 the Northern Territory (NT) government re-introduced the Banned Drinker Register (BDR) to address the high rates of alcohol related harm. This paper aims to evaluate whether trends in assault, maltreatment and sentinel injuries in children and adolescents were associated with the re-introduction of the BDR, in the context of other local interventions such as police officers stationed in bottle shops being partially removed, Police Auxiliary Liquor Inspectors, and the introduction of a minimum unit price of alcohol.

METHOD

Interrupted time series analysis was used to assess monthly trends in emergency department presentations and inpatient hospital admissions for assault, maltreatment and sentinel injuries between January 2014 and December 2019 in the regions of Greater Darwin, Alice Springs, and Katherine.

RESULTS

A significant step increase after the introduction of the BDR in emergency department presentations for assault and maltreatment was present when examining the three regions combined (β = 7.65, 95 % CI = 2.15, 13.16). However, this was not present at the individual community level. Results across a range of other models pointed towards null effects of the BDR introduction.

CONCLUSIONS

The current study found that the re-introduction of the BDR had minimal impact on rates of assault, maltreatment, or sentinel injuries in children and adolescents. To ensure long-term harm mitigation from alcohol use, a combination of evidence informed alcohol policies that address the price and availability of alcohol in a comprehensive framework, along with measures which address the underlying social determinants of unregulated drinking and health more broadly will assist in reducing alcohol related harm in both children and adults.

Is high exposure to antisocial media content associated with increased participation in malicious online trolling? exploring the moderated mediation model of hostile attribution bias and empathy

Malicious online trolling is prevalent among Chinese college students and has recently garnered extensive attention from researchers due to the substantial harm it causes to the victims and the damage it inflicts on the online environment. Most previous studies have focused on examining how personal traits related to malicious online trolling. Further comprehensive research is needed to explore the mechanisms linking external environmental factors (antisocial media exposure) and malicious online trolling. A total of 1259 Chinese college students completed questionnaires regarding malicious online trolling, antisocial media exposure, hostile attribution bias, and empathy. The results indicated a positive association between antisocial media exposure and malicious online trolling among Chinese college students, with hostile attribution bias serving as a mediating factor. Furthermore, the direct and mediated paths between antisocial media exposure and malicious online trolling were moderated by empathy. Specifically, as the level of empathy increased among college students, the relations between the variables all weakened. Excessive exposure to antisocial media content among college students may trigger hostile attribution bias and lead to more malicious online trolling behavior. However, the relation between antisocial media exposure and malicious online trolling, hostile attribution bias and malicious online trolling, was attenuated when college students' empathy levels were high.

The transition from physical sibling abuse to bullying perpetration through trait anger: A longitudinal study

OBJECTIVES

Experiencing physical sibling abuse is a form of family violence that is common but understudied. While it is often perceived as a normative aspect of sibling relationships, there are apparent behavioral consequences. The current study aims to advance the literature by utilizing the displaced aggression model and I3 theory to longitudinally examine trait anger as a pathway linking physical sibling abuse to bullying perpetration.

METHODS

Using data from the Bullying, Sexual, and Dating Violence Trajectories from Early to Late Adolescence in the Midwestern United States, 2008-2013, adolescents (n = 851, M = 14.8 years) completed questionnaires at baseline and were reassessed 6 months later.

RESULTS

Results suggested that when adolescents experience physical sibling abuse, they are more likely to engage in bullying perpetration. Mediation analyses indicated that as adolescents were physically abused by a sibling at home, they were more likely to report higher levels of trait anger, which subsequently increased their risk of engaging in bullying perpetration.

CONCLUSION

These results suggest that experiencing physical sibling abuse has long-term detrimental consequences, including elicitation of trait anger, subsequently predicting bullying perpetration.

Factors Associated with Sexual Victimization Among Transgender Emerging Adults

This cross-sectional study documented between-group differences in risk factors associated with sexual victimization histories in an ethnically and racially diverse sample of transgender emerging adults (N = 248, ageM = 22.61 years). The sample was recruited using the Internet-based CloudResearch platform to answer questionnaires assessing predictors for recent experiences of intimate partner violence (IPV). Participants were categorized into four groups based on cross-classified self-reports of child sexual abuse (CSA) and recent sexual IPV, prior to the use of multivariate analysis of variance to evaluate mean score differences for past-year substance use, minority stressor, and relationship functioning variables. Participants reporting sexual IPV reported higher scores for all substance use variables, while transfeminine participants reported significantly higher scores for alcohol use problems and negative consequences related to substance use. Participants reporting both CSA and sexual IPV also reported the highest scores for everyday discrimination. Participants who experienced sexual IPV also reported the highest scores for internalized sexual stigma. Sexual revictimization among transgender adults occurs in the context of harmful patterns of substance use and several minority stressors. Our findings have implications for healthcare or counseling services for transgender emerging adults who have experienced multiple forms of victimization, substance use problems, and minority stressors, including the importance of trauma-informed and integrated intervention services, and specialized training for service providers.

What are the impacts of alcohol supply reduction measures on police-recorded adult domestic and family violence in the Northern Territory of Australia?

BACKGROUND

During 2017-18, the Northern Territory (NT) introduced a Banned Drinker Register (BDR) and Minimum Unit Price (MUP) NT-wide; Police Auxiliary Liquor Inspectors (PALIs) in three regional towns; and restrictions on daily purchases/opening hours (DPOH) in one regional town. The BDR is an individual-level alcohol ban; MUP is a pricing policy; and PALIs enforce bans on restricted areas at takeaway outlets. This study examines the impact of these policies on adult domestic and family violence (DFV).

METHODS

We examined DFV assaults and breaches of violence orders from January 2014 - February 2020 using interrupted time series models for NT, Greater Darwin, Katherine, Tennant Creek, and Alice Springs. To account for increasing numbers of individuals on the BDR we tested two timepoints (Sept 2017, March 2018).

FINDINGS

Following DPOH, assaults (78 %) and alcohol-involved assaults (92 %) decreased in Tennant Creek. After PALIs, assaults (79 %) in Tennant Creek, and breaches (39 %) and alcohol-involved breaches (58 %) in Katherine decreased. After MUP, assaults (11 %), alcohol-involved assaults (21 %) and alcohol-involved breaches (21%) decreased NT wide. After MUP/PALIs in Alice Springs, alcohol-involved assaults (33 %), breaches (42 %), and alcohol-involved breaches (57 %) decreased. BDR (Sept 2017) found increases in assaults (44 %) and alcohol-involved assaults (39 %) in Katherine and assaults (10%) and alcohol-involved assaults NT-wide (17 %). There were increases of 21 %-45 % in breaches NT-wide, in Darwin, Katherine, and Alice Springs. Following March 2018 found increases in assaults (33 %) and alcohol-involved assaults (48 %) in Katherine. There were increases - from 20 % to 56 % - in breaches in NT-wide, Katherine, and Alice Springs.

CONCLUSION

PALIs and DPOH were associated with some reductions in DFV; the BDR was associated with some increases. The upward trend commences prior to the BDR, so it is also plausible that the BDR had no effect on DFV outcomes. Although MUP was associated with reductions in the NT-wide model, there were no changes in sites without cooccurring PALIs.

Predicting aggressive behaviors: Examining unique and interactive roles of PTSD and emotion dysregulation in a minority sample

Aggression is a costly public health problem with severe and multi-faceted negative consequences and thus, identifying factors that contribute to aggression, particularly in understudied populations, is necessary to develop more effective interventions to reduce the public health cost of aggression. The goal this study was to test whether difficulties regulating emotions moderated the association between posttraumatic stress disorder (PTSD) symptoms and aggression in a community sample of predominantly Black females with high levels of trauma exposure. Furthermore, we explored unique relations between PTSD symptom clusters and distinct subscales of difficulties regulating emotions and aggression. The sample included 601 community participants recruited from an urban public hospital. Symptoms were assessed using self-report measures including the Difficulties in Emotion Regulation Scale (DERS) and Behavioral Questionnaire-Short. Regression analyses were conducted using PTSD symptoms and total DERS to test their interaction as predictors for aggression (using BQ-Short). We found that higher levels of PTSD arousal symptoms and difficulty controlling impulses when upset were positively related to aggression. We also conducted an exploratory analysis to examine the association between PTSD symptom clusters using the Alternative Symptom Clusters hybrid model. The results suggest that some PTSD symptoms (externalizing behavior) and some emotion dysregulation processes (difficulties controlling impulses when upset), relate to aggression in independent, rather than multiplicative ways. These results offer insights for new directions of research that focuses on the independent association between specific emotion dysregulation processes and PTSD symptoms on aggression.

Daily life affective dynamics as transdiagnostic predictors of mental health symptoms: An ecological momentary assessment study

BACKGROUND

Affective dynamics have been identified as a correlate of a broad span of mental health issues, making them key candidate transdiagnostic factors. However, there remains a lack of knowledge about which aspects of affective dynamics - especially as they manifest in the course of daily life - relate to a general risk for mental health issues versus specific symptoms.

METHODS

We leverage an ecological momentary assessment (EMA) study design with four measures per day over a two-week period to explore how negative affect levels, inertia, lability, and reactivity to provocation and stress in the course of daily life relate to mental health symptoms in young adults (n = 256) in the domains of anxiety, depression, psychosis-like symptoms, behaviour problems, suicidality, and substance use.

RESULTS

Dynamic structural equation modelling (DSEM) suggested that negative affect levels in daily life were associated with depression, anxiety, indirect and proactive aggression, psychosis, anxiety, and self-injury; negative affective lability was associated with depression, physical aggression, reactive aggression, suicidal ideation, and ADHD symptoms; negative affective inertia was associated with depression, anxiety, physical aggression, and cannabis use; and emotional reactivity to provocation was related to physical aggression.

LIMITATIONS

The cross-sectional design, the limited span of mental health issues included, and the convenience nature and small size of the sample are limitations.

CONCLUSIONS

Findings suggest that a subset of mental health symptoms have shared negative affective dynamics patterns. Longitudinal research is needed to rigorously examine the directionality of the effects underlying the association between affective dynamics and mental health issues.

Towards the understanding of the core of general personality disorder factor: g-PD and its relation to hostile attributions

There is a general consensus that personality disorders (PDs) share a general factor (g-PD) overlapping with the general factor of psychopathology (p-factor). The general psychopathology factor is related to many social dysfunctions, but its nature still remains to some extent ambiguous. We posit that hostile attributions may be explanatory for the factor common for all PDs, i.e., interpersonal problems and difficulty in building long-lasting and satisfying relationships of all kinds. Thus, the main objective of the current project was to expand the existing knowledge about underlying factors of g-PD with regard to hostile attributions. We performed a cross-sectional study on a representative, community sample of Poles (N = 1031). Our hypotheses were primarily confirmed as hostile attributions predicted p-factor. However, the relation was positive only for hostile attributions related to ambiguous situations involving relational harm and physical harm done by female authorities and negative in case of hostile attributions in situations involving physical harm done by peers. Additionally, paranoia-like thoughts strongly related to hostile attributions and independently predicted g-PD. The results contribute to the current discussion on the nature of the g-PD, confirm that hostile attributions and paranoia are a crucial aspect of personality pathology, and indicate the importance of working on these cognitions in the course of therapeutic work.

Examining the role of posttraumatic stress disorder symptoms in intimate partner violence among couples with alcohol use disorder

Separate literatures indicate that both alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) are robust risk factors for using intimate partner violence (IPV). Despite the strength of these relative literatures, and the common co-occurrence of AUD and PTSD, their combined effects on IPV have rarely been examined. This study begins to address this gap by exploring the moderating effects of provisional PTSD diagnosis on the relation between heavy alcohol consumption and physical IPV using a multilevel modeling approach. Participants were adult romantic couples (N = 100) with current AUD and a history of physical IPV in their relationship. Results from the between-couple comparison indicate that couples who reported more heavy drinking days also experienced more physical IPV when at least one partner had probable PTSD. However, the within-couple comparison indicated that among partners without a provisional PTSD diagnosis, those with fewer heavy drinking days compared to their partner also reported more physical IPV perpetration. These preliminary and exploratory findings require replication and extension but provide new and important information regarding the complex intersection of heavy drinking, PTSD, and IPV among couples with AUD.

The effect of aggressive fantasizing on aggressive inclinations: Moderating effects of dispositional anger expression

Experiencing victimization or mistreatment often induces feelings of anger. The catharsis hypothesis suggests that venting anger may aid in alleviating these negative emotions. Although this hypothesis has faced criticism, therapeutic interventions rooted in catharsis are employed to assist victims in managing their anger. One notable application of the catharsis principle in psychotherapeutic practice with victims involves engaging in aggressive fantasies: Victims who harbor aggressive fantasies against their offenders are supported in working with these fantasies to navigate the complex emotions arising from their victimization. Research investigating the effects of aggressive fantasizing on victims has yielded inconsistent findings, with some studies indicating positive and others suggesting negative outcomes. Herein, we examine whether (instructed) aggressive fantasizing diminishes (catharsis hypothesis) or heightens (escalation hypothesis) subsequent aggressive inclinations compared to non-aggressive fantasizing. Additionally, the moderating role of victims' dispositional tendencies to express anger, specifically Anger Expression-out and Anger Expression-control, in the relationship between aggressive fantasizing and aggressive inclinations was examined. We recruited individuals (N = 245) who had experienced victimization through highly unfair treatment and instructed them to imagine confronting their wrongdoer using either aggressive or non-aggressive communication. Participants then reported their aggressive inclinations. Data supported the escalation hypothesis, revealing that aggressive fantasizing amplifies subsequent aggressive inclinations. Importantly, individuals with higher Anger Expression-out demonstrated greater susceptibility to this effect; whereas, Anger Expression-control did not moderate the link between aggressive fantasizing and inclinations. These findings further challenge the catharsis hypothesis and underscore the role of dispositional anger expression tendencies on the effects of aggressive fantasizing.

Interactive effects of mindfulness and negative urgency on intimate partner aggression perpetration

Intimate partner aggression (IPA) is a costly and incompletely understood phenomenon. Negative urgency, the tendency to act impulsively in response to negative affect, is predictive of IPA perpetration. Mindfulness, by virtue of its emphasis on nonreactivity to negative affect, is an opposing force to urgent tendencies that may mitigate the negative urgency-IPA link. Yet, no research to date investigates the interactive effects of negative urgency and mindfulness on IPA perpetration. Two studies were conducted that measured and manipulated multiple facets of mindfulness alongside measures of negative urgency and tendencies of IPA perpetration (combined N = 508 undergraduate students in monogamous intimate relationships). Counter to our preregistered predictions, we found that negative urgency's association with greater IPA perpetration increased at higher levels of mindfulness. These findings suggest that mindfulness may not be a protective factor against IPA perpetration for individuals higher in negative urgency, but rather may serve as a risk factor.

Validation of the Violent Ideations Scale (VIS) in Spain

Research has shown that violent ideations (VIs) may play a key role in aggression and violence. However, there is no tool to measure this construct adapted to the Spanish language so far. The current study aims to translate and evaluate the psychometric properties of the Violent Ideations Scale (VIS) in European Spanish. This study counts with a convenience sample of 752 native Spaniards or Spanish speakers residing in Spain, between 18- and 75-years old, 53% identified as female and 47% identified as male. The dimensionality, gender measurement invariance, concurrent validity and reliability of scores were assessed. Initial evidence of external validity was collected. Results confirmed the unidimensionality of the instrument. Measurement invariance held across females and males and reliabilities were high. VIS-ES scores correlated with aggressive behavior during the previous month. The VIS-ES seems suitable for use in non-clinical Spanish speaking samples.

The Impact of COVID-19 on Trends of Violence-Related Offences in Australia

OBJECTIVE

To investigate the medium-term impacts of the COVID-19 pandemic on violence-related offences in Australia, and whether there was evidence of a 'dual pandemic' of family violence in addition to COVID-19.

METHODS

Autoregressive Integrated Moving Average time series were conducted to analyse publicly available violent crime statistics data from January 2017 to November 2021. Population rates of homicide, sexual, domestic and non-domestic assault were assessed across each Australian state and territory, with the effects of COVID-19 being modelled using the average monthly World Health Organization COVID-19 stringency rating for each jurisdiction.

FINDINGS

All jurisdictions in Australia showed increasing or stable domestic assault trends over the past decade, which were not significantly impacted by COVID-19, nor by the subsequent lockdowns. Non-domestic assaults demonstrated a significant, negative relationship with the stringency index for each jurisdiction, except Western Australia. There was no significant change in the rates of homicide or sexual assault across Australia in relation to COVID-19.

CONCLUSION

Overall, there was no evidence of a 'dual pandemic' in Australia, and whilst domestic assaults continue to increase across the country, non-domestic assaults showed a notable but brief decline. However, these have returned to levels at least as high as pre-COVID-19 and some states show a continuing upward trend. The findings also suggest that alcohol availability may have played a role in continuing high violence numbers. Given the ongoing increasing and high levels of family violence in Australia, revised conceptual frameworks and interventions are indicated.

Generating a Moderated Mediation Model of Positive Outcome Expectancy and Aggression

According to previous theories of aggression, positive outcome expectancy for aggression can predict aggression, while moral disengagement and negative outcome expectancy for aggression may, respectively, serve as mediators and moderators in this prediction process. To test the hypothesis, Study 1 first developed the Aggression Outcome Expectancy Questionnaire and examined its two-factor structure, which consists of positive and negative outcome expectancy for aggression. Next, 677 college students were recruited to participate in Study 2 and were asked to complete the Aggression Outcome Expectancy Questionnaire, Civic Moral Disengagement Questionnaire, and Buss-Perry Aggression Questionnaire. The findings indicated the following: (1) The Aggression Outcome Expectancy Questionnaire for college students demonstrated acceptable reliability and construct validity, confirming the two-factor structure of aggression outcome expectancy. (2) After controlling for sex and age, moral disengagement partially mediated the relationship between positive outcome expectancy and aggression. (3) Negative outcome expectancy for aggression moderated the effect of positive outcome expectancy on aggression, as well as moral disengagement. Specifically, negative outcome expectancy for aggression attenuated the positive predictive effect of positive outcome expectancy on aggression and moral disengagement. In conclusion, the present study extends our understanding of the motivational mechanism of aggression, offering a theoretical reference for preventing and intervening in aggressive behavior among college students.

Multivariate Patterns of Substance Use, Minority Stress and Environmental Violence Associated with Sexual Revictimization of Lesbian and Bisexual Emerging Adult Women

This study documented between-group differences in factors associated with sexual revictimization histories in a sample of young sexual minority women. Diverse samples of lesbian (N = 204, age_M = 23.55 years) and bisexual (N = 249, age_M = 23.35 years) women from the United States were recruited using the CloudResearch platform to assess factors associated with recent experiences of intimate partner violence (IPV). Participants were categorized into four groups based on self-reports of sexual victimization (a) during childhood and (b) during adulthood in intimate relationships. Multivariate Analysis of Variance (MANOVA) was used to model between-group differences in three variable domains: Past-year substance use involvement, minority stress, and violence in relationship and community settings. Lesbian women reporting sexual revictimization in adulthood reported significantly higher scores for measures of past-year substance use involvement and negative consequences, daily discrimination experiences, relational victimization, and criminal victimization, compared to their counterparts with no history of sexual victimization. Among bisexual women, sexual revictimization was associated with a similar pattern of between-group differences. The sexual revictimization experiences of sexual minority women appear to occur in the context of multivariate patterns of harmful substance use, minority stress, and violence in both relationship and community settings. Our findings have implications for how intervention services are provided to emerging adult sexual minority women who experience multiple episodes of sexual abuse during their lifespans. Recommendations include specialized training for counseling or intervention service providers, integrated trauma-informed services that address both substance use and sexual assault issues, and affirmative services for sexual minority women.

An Application of the Confluence Model of Sexual Aggression Among Young Adult Male Soldiers

Sexual violence in the U.S. military is a serious concern. Whereas numerous studies document the prevalence of sexual violence among service members, far less research has examined etiological risk factors for sexual aggression perpetration among service members. The present study sought to evaluate the applicability of the Confluence Model of Sexual Aggression among a sample of young adult men engaged in active-duty military service within the U.S. Army. Anonymous surveys were completed by 326 male soldiers between the ages of 18 and 24 at a large military installation in the Southeastern region of the United tStates. Men's likelihood to engage in sexual aggression was operationalized as men's perceived likelihood to persist with sexual activity despite a partner's resistance. Aligning with the Confluence Model of Sexual Aggression, two composite variables reflecting hostile masculinity and tendency toward impersonal sex were created. A linear regression indicated that the main effects of hostile masculinity and impersonal sex were significantly associated with greater perceived likelihood of sexual aggression perpetration. Results also revealed that while the interaction term between hostile masculinity and impersonal sex was significant, the direction of the relationship suggests that the effect of impersonal sex is weaker at higher levels of hostile masculinity. These findings lend evidence to help identify those at elevated risk for perpetrating sexual aggression, as well as informing programmatic efforts to prevent sexual assault within the military.

Problem Drinking is Associated with Intimate Partner Cyber Abuse Perpetration but is Buffered by High Relationship Satisfaction

Purpose

Intimate partner cyber abuse (IPCA) is a prevalent form of intimate partner violence (IPV) that has detrimental effects on victims' well-being. Although research has documented associations with other forms of IPV perpetration, additional research is needed to identify IPCA perpetration risk factors. One of the most common risk factors for offline IPV is perpetrators' alcohol use; however, less is known about how this translates to online contexts. There is also a need to identify protective factors that mitigate the effects of alcohol.

Methods

This study evaluated associations between drinking, relationship satisfaction, and IPCA perpetration via self-report questionnaires within a longitudinal framework. Participants included 544 adults in an intimate relationship (n = 296 at T2).

Results

Results indicated that relationship satisfaction buffered the effects of problem drinking on IPCA perpetration at T1, but not at T2. Further, 20.2% of individuals who perpetrated IPCA at T1 drank alcohol during at least one incident, and these individuals reported more problem drinking and more frequent IPCA perpetration compared to those who reported IPCA without alcohol.

Conclusion

Results from this study provide insight into both risk and protective factors for IPCA perpetration among adults and have the potential to guide concurrent prevention strategies that target intersections between problem drinking, IPCA, and offline IPV, and promote healthy and satisfying intimate relationships.

The Management of Workplace Violence against Healthcare Workers: A Multidisciplinary Team for Total Worker Health® Approach in a Hospital

The risk of aggression against healthcare workers (HCWs) is a globally well-known topic. However, workplace violence (WV) is often considered as part of HCW’s job, leading to a general underreporting. This cross-sectional study aims at providing a descriptive analysis of aggressive acts against HCWs registered in a 34-month period in a pediatric hospital. According to a specific protocol, each aggressive act was analyzed by a multidisciplinary team using the “Modified Overt Aggression Scale” (MOAS), the “General Health Questionnaire-12” (GHQ-12), and the “Short Form-36 Health Survey” (SF-36) to build a report addressing improvement measures. A three-domain model of WV was also developed considering: (1) assaulted HCWs, (2) attacker-related issues, and (3) environmental context. Contributing factors to overt aggression were outlined and tested using univariate analyses. Statistically significant factors were then included in a multiple linear regression model. A total of 82 aggressive acts were registered in the period. MOAS scores registered a mean value of 3.71 (SD: 4.09). Verbal abuse was the most common form of WV. HCWs professional category, minor psychiatric disorder, emotional role limitation, type of containment used, and emotion intensity were significantly associated with overt aggression (p < 0.05), as well as the attacker’s role in the hospital (p < 0.05). The multiple regression analysis confirmed these findings (p < 0.001). Raising awareness on the aggression risk and contributing factors may lead to a relevant improvement of workplace environment, individual workers’ health, and organizational well-being.

Family Incivility and Cyberbullying Perpetration Among College Students: Negative Affect as a Mediator and Dispositional Mindfulness as a Moderator

Although family factors are associated with cyberbullying, few studies have investigated the relationship between family incivility and cyberbullying perpetration. The current study aimed to examine the associations between family incivility and cyberbullying perpetration among college students, and further investigate the underlying moderated mediation mechanism. Study 1 was a cross-sectional survey among 640 Chinese undergraduate students (M_age = 20.29 years, SD = 1.38). Demographics, family incivility, cyberbullying perpetration, and negative affect were assessed. The results supported the idea that negative affect plays a role in mediating the relationship between family incivility and cyberbullying perpetration. Study 2 used a two-wave longitudinal design, aiming to examine both the mediating role of negative affect and the moderating role of dispositional mindfulness (represented through five facets-observing, describing, acting with awareness, nonjudging, and nonreacting-each of which were analyzed separately). The data were collected from 200 Chinese undergraduate and graduate students (M_age = 22.18, SD = 2.56). Negative affect was also found to play a mediation effect in this study. Furthermore, the results found that acting with awareness and nonjudging weakened the relationship between family incivility and negative affect, whereas observing exacerbated it. Moreover, nonjudging exacerbated the relationship between negative affect and cyberbullying perpetration. The present findings indicate that negative affect may play a role in explaining the association between family incivility and cyberbullying perpetration. Furthermore, acting with awareness and nonjudging could buffer the relationship between family incivility and cyberbullying perpetration via negative affect, which provides a new insight for the prevention of and intervention on cyberbullying perpetration.

The centrality of cognition and coping styles in driving aggressive responses

OBJECTIVE

Despite the presence of theoretical frameworks explaining aggression, they still require refinement in the form of a specification of mechanisms that facilitate such behaviour.

METHOD

Study 1 recruited participants (N = 31) from the general population (N = 20) and from a forensic hospital (N = 11). It was expected that aggression supportive cognitions and stress would be positively associated with aggressive behaviour. An experimental paradigm was used to induce stress and participants were subsequently given the opportunity to aggress. Study 2 was based on self-report questionnaires in community sample (N = 462). It was expected that aggressive behaviour and traits would be associated with experienced stress, hostile attributions, coping styles, and attitudes to violence. Specifically, that criminal attitudes to violence will mediate the effect of hostile attribution on aggression, while coping styles will mediate the effect of perceived stress.

RESULTS

An Implicit Theory "I am the law" was found to be associated with aggression. Furthermore, elevated skin conductance, but not changes in the heart rate, during the stress task was positively associated with aggression, and only among patients. Structural Equation Model confirmed the mediating role of criminal attitudes to violence and of maladaptive coping style for aggressive behaviour.

CONCLUSION

Aggression-supportive cognitions and maladaptive coping style are specific mechanisms through which external demands or subjective perception of a situation can result in aggressive behaviour.

The Dark Tetrad, cybervictimization, and cyberbullying: The role of moral disengagement

Cyberbullying is a form of antisocial online behaviors. Perpetration of intentional and repeated harm inflicted through electronic devices is associated with dark personality traits and may be caused by morally impaired reasoning. In the current study, we investigated the associations between the Dark Tetrad (narcissism, Machiavellianism, psychopathy, sadism), cybervictimization, and cyberbullying. We also examined the intervening role of moral disengagement in the relationship between the Dark Tetrad and cyberbullying. Two hundred fifty-one adults (72.6% women) participated in an on-line study. Correlational analysis indicated that all dark personality traits were associated with higher cyberbullying and cybervictimization (except narcissism as a predictor of cybervictimization). Moral disengagement was positively related to Machiavellianism, sadism and cybervictimization. Controlled for covariance between the Dark Tetrad traits and cybervictimization, sadism and cybervictimization appeared to be associated with cyberbullying. Moreover, moral disengagement did not account for the associations between the Dark Tetrad and cyberbullying.

Illicit drug use and male barroom aggression among members of the Australian construction industry: Associations with personality and masculinity factors

Introduction

Illicit drug use has been found to increase the risks of male barroom aggression (MBA). Personality traits such as dispositional aggressiveness have been associated with illicit substance use and aggressive behaviour, along with social normative masculinity factors. The present study assessed the relationships between illicit drug use, key personality (trait aggression, impulsivity, narcissism) and masculinity (conformity to masculine norms, male honour) variables with physical MBA perpetration and victimisation among male Australian construction workers.

Methods

A purposive, high‐risk sample of male construction workers aged 18–69 years (n = 476, M_age = 25.90 years, SD_age = 9.44) completed interviews at their place of work or training.

Results

Participants reported high rates of both physical MBA perpetration (21%; n = 100) and victimisation (31.1%; n = 148) as well as any illicit drug use (33.61%; n = 160). Logistic regressions revealed the use of amphetamine‐type stimulants (methamphetamine, ecstasy) was associated with violence perpetration, even after accounting for high‐intensity drinking (HID) which was the strongest predictor of MBA involvement. Trait variables (Trait Physical aggressiveness, narcissism) and the masculine norm CMNI Violence were also risk factors for MBA perpetration while CMNI Playboy was protective against MBA.

Discussion and Conclusions

The use of amphetamine‐type stimulants is a risk‐factor for MBA perpetration, as are key personality traits such as aggressiveness and narcissism. Most aspects of masculinity, including male honour, were either unrelated to or protective against involvement in physical violence in bars, clubs or pubs.

Police Officers' Interrogation Expertise and Major Objectives in Police Service and Training: A Comprehensive Overview of the Literature

Interrogation is a core task of practical police work. The outcomes of interrogation often provide crucial evidence for solving criminal cases. The success of interrogation depends on interactions between police officers and citizens. Based on a comprehensive literature overview, we propose a three-factor typology for interrogations by police officers. First, the competencies of police officers refer to the application of personal, professional, social, and methodological capabilities. The underlying concept of interrogation refers to the application of both explicit and implicit experience-based interrogation models. Communication refers to the goal-directed application of communication tactics and techniques. According to this typology, we discuss the major objectives of police interrogation in police service and training from police officers' perspectives. The present study provides guidance for practical police services and training by offering an evidence-based interrogation standard.

Emotional Regulation in Male Batterers When Faced With Pictures of Intimate Partner Violence. Do They Have a Problem With Suppressing or Experiencing Emotions?

Emotional regulation is crucial to psychological functioning and mental health. Studies of male batterers indicate the critical role that emotional processing plays in the violence they exert upon their partners or ex-partners. The aim of this study was to investigate the neural bases of emotional regulation in male batterers-both in experiencing and suppressing emotions-when faced with pictures of intimate partner violence (IPV). We conducted a fMRI study to compare brain functioning when emotions were experienced or increased with the case in which emotions were suppressed or reduced in response to IPV pictures and unpleasant pictures. The sample consisted of three groups: Male Batterers Group (MBG, n = 26), that is, men convicted for IPV; Other Offenders Group (OOG, n = 27), men convicted of crimes other than IPV; and a Non-offenders Group (n = 29), that is, men without a criminal history. The results reveal that in MBG, the brain areas that previous studies have related to suppression and experience processes were activated when faced with unpleasant pictures. However, a different pattern of functioning was found when experiencing IPV pictures. That could be explained by a low capacity to empathize with their partners or ex-partners and by the use of maladaptive emotional regulation strategies. In addition, MBG showed activation in brain areas previously related to suppression but did not modulate their emotions, showing a similar emotional state after suppression and experience. The results of this preliminary study suggest that in psychological treatments for male batterers, it is important to promote empathy towards partners or ex-partners, along with adaptive strategies of emotional regulation.

Emotion Regulation Difficulties and Health-Risk Behaviours in Adolescents

Health-Risk Behaviours (HRBs) are significantly associated with avoidable mortality in adolescents, and preventing HRBs requires an adequate understanding of related factors. Among associated factors, emotion regulation difficulties may impact youths’ engagement in HRBs. Researchers explored the relation of emotion regulation with HRBs; however, specific emotion regulation difficulties for less severe and more prevalent HRBs, such as self-harming behaviour, risky-driving, violence, unhealthy dietary behaviour, and poor adherence to prescribed medication, has not been much explored. The current study aimed to explore the predictability of adolescents’ specific difficulties in emotion regulation in relation to their engagement in HRBs. For this purpose, six different HRBs, that is, self-harm, violence, risky-driving, unhealthy dietary behaviour, inadequate physical activity, and lack of medication adherence, were studied. A total of 617 (Males = 356) adolescents (Mage = 15.77) from five districts of Punjab state (India) provided required information on standardised self-report measures. The data were subjected to regression analysis, and the findings show that the participants who scored high on emotion regulation difficulties reported engagement in HRBs more than their counterparts. Some specific difficulties are more important than others for different forms of HRBs. It implies that the intervention programmes targeting specific HRBs should address specific facets of emotional dysregulation.

Does mindfulness reduce trolling? The relationship between trait mindfulness and online trolling: The mediating role of anger rumination and the moderating role of online disinhibition

BACKGROUND

Online trolling is a highly prevalent online antisocial behaviour that has recently received increasing attention because of its potentially destructive consequences. The current study aimed to examine whether trait mindfulness was negatively related to online trolling and whether anger rumination mediated this relationship. We further examined whether online disinhibition moderated the direct and indirect relation between trait mindfulness and online trolling.

METHODS

A total of 1303 Chinese college students completed the measurements of trait mindfulness, anger rumination, online disinhibition, and online trolling. Moderated mediation analysis was performed to examine the relationships between these variables.

RESULTS

After controlling for sex, the results showed that trait mindfulness was negatively related to online trolling and that this relationship was partially mediated by anger rumination. Moreover, the effect of anger rumination on online trolling was strengthened when online disinhibition was high.

LIMITATIONS

This study is a cross-sectional study, and causal inferences cannot be drawn.

CONCLUSIONS

Individuals with trait mindfulness are less likely to ruminate anger and further express less online trolling. Online disinhibition serves as a risk factor for online trolling. Interventions targeting trait mindfulness, anger rumination, and online disinhibition might aid prevention strategies.

Reduced salivary oxytocin after an empathic induction task in Intimate Partner Violence perpetrators: Importance of socio-affective functions and its impact on prosocial behavior

Intimate Partner Violence (IPV) has been linked to difficulties in socio-affective functions. Nevertheless, the underlying psychobiological mechanisms that might be responsible for them remain unclear. Oxytocin (OXT) stands out as an important hormone that may favor the salience of social information, due to its relevance in empathy and prosocial behavior. Thus, the study of salivary OXT (sOXT) may provide further information about potential impairments in social cognition in IPV perpetrators. This study analyzed the effects of an empathic induction task, performed through negative emotion-eliciting videos, on endogenous sOXT levels, mood state, and emotional perception in 30 IPV perpetrators compared to 32 controls. Additionally, we explored their performance on prosocial behavior after the empathic induction task, using Hare's donation procedure. Lower sOXT levels were found in IPV perpetrators after the task compared to controls, along with a general decreasing tendency in their sOXT levels. Additionally, IPV perpetrators exhibited no change in their mood state and perceived others' emotions as more positive and less intense. Moreover, the mood state response and alexithymia traits, respectively, positively and negatively predicted the sOXT levels after the empathic induction task in the entire sample. Finally, we did not observe a lower appearance of prosocial behaviors in IPV perpetrators; however, higher sOXT levels after the empathic induction task were found in subjects who donated when considering the whole sample. In sum, IPV perpetrators exhibited differences in their sOXT levels when empathizing, compared to controls, with alexithymia and the emotional response potentially explaining the sOXT levels after the task. Furthermore, prosocial behavior was more related to these sOXT levels than to IPV. As our knowledge about the emotional processing of IPV perpetrators increases, we will be better able to develop and include coadjutant treatments in current psychotherapeutic programs, in order to focus on their emotional needs, which, in turn, would reduce the future risk of recidivism.

Substanzkonsum – Sucht – Gewalt: Zusammenhänge, Risiken, Prävention

Zwischen Substanzkonsum und Gewaltverhalten besteht ein enger Zusammenhang, der durch Schlüsselsituationen, veränderte Risikowahrnehmung und -beurteilung sowie verminderte Aggressionshemmungen gekennzeichnet ist. Zu den aktuellen Konzepten zur Einschätzung des Zusammenhangs zwischen Substanzkonsum und Gewalt zählt das I3-Modell, das die Faktoren Anstiftung, Schlagkraft und Hemmung in einen Zusammenhang zwischen der konsumierenden Person und der Risikosituation bringt. Inzwischen liegen Programme zur Prävention und Intervention bei suchtmittelassoziierter Gewalt vor, wie z. B. TAVIM, die im Behandlungssystem stärkere Verankerung erfahren sollten.

Personal Risk and Protective Factors Involved in Aggressive Behavior

The study of aggression plays a prominent role in psychology and public health, because of the important adverse consequences of such behavior for victims, aggressors, and society in general. The General Aggression Model (GAM) provides a general conceptual framework for understanding the aggressive as a result of three stages: (a) inputs: personal and situational factors; (b) present internal states: affect, cognition, and arousal; and (c) outcomes: decision processes with a (non)aggressive result. The main objective of this research was to study the personal protective and risk factors most strongly associated with aggressive behavior acting at the first stage of the GAM model. A total of 282 young adult participants took part in this study. Participants were assessed for aggression levels and a set of the most relevant variables that have been associated with aggressive behavior in the previous literature. Stepwise multiple regression analysis revealed that levels of aggression were mainly associated (73.2% of the explained variance) with the following protective factors: the ability to manage emotions as a component of emotional intelligence (EI), and perspective-taking and personal distress as components of empathy, and with the following risk factors: negative and positive urgency as a component of impulsivity, fantasy as a component of empathy, negative affect, and expressive suppression of emotions. These findings provide a better understanding of the mechanisms underlying aggressive behavior and provide greater empirical value to the current theoretical models. In addition, this research can help to inform the design of more successful programs for the prevention, control, and treatment of aggressive behavior. Limitations and future lines of research are discussed.

Impulsivity and Perpetration of Intimate Partner Aggression: The Moderating Effects of Negative Affective State and Alcohol

Background: The goal of this study was to test the interactive effects of negative urgency, state negative affect, and alcohol intoxication on intimate partner aggression (IPA) perpetration. Methods: Heavy drinkers who recently perpetrated IPA completed self-report measures of impulsivity, were administered an alcohol or control beverage, and completed a laboratory aggression task. State negative affect was assessed unobtrusively via the Facial Action Coding System. Results: Consistent with our prediction, negative urgency was significantly and positively related to IPA when state negative affect was also high, but this relation was not significant when state negative affect was low. Conclusions: These results have implications for understanding the role of negative affect and impulsivity in IPA perpetration and for understanding trait models of impulsivity in general.

Physical and Sexual Intimate Partner Aggression Among College Students: Examining the Roles of Cyber Intimate Partner Aggression and Alcohol Use

Intimate partner aggression (IPA) is a serious and prevalent problem among college students. Two factors that may increase risk for in-person IPA are cyber IPA and alcohol use. This study examines the interaction between three types of cyber IPA (cyber psychological, stalking, and sexual IPA) and alcohol use in predicting in-person physical and sexual IPA perpetration. Participants were 268 undergraduate students, who participated in a mass screening at a large midwestern university. More than half of the sample reported perpetrating cyber IPA. A multivariate logistic regression model was used to examine study hypotheses. The R² for physical IPA perpetration was .69 and the R² for sexual IPA perpetration was .46. Cyber stalking IPA and alcohol interacted to predict physical IPA perpetration, such that the relationship between cyber stalking IPA and physical IPA perpetration was stronger among individuals who used more alcohol. Contrary to expectations, cyber IPA and alcohol did not interact to predict sexual IPA. However, consistent with hypotheses, cyber stalking IPA was positively associated with sexual IPA perpetration. The high prevalence of cyber IPA and its association with in-person IPA perpetration suggests that prevention programs targeting cyber IPA on college campuses may be warranted.

Neural mechanisms of intimate partner aggression

People sometimes hurt those they profess to love; yet our understanding of intimate partner aggression (IPA) and its causes remains incomplete. We examined brain activity using functional magnetic resonance imaging (fMRI) in an ethnically and racially diverse sample of 50 female-male, monogamous romantic couples as they completed an aggression task against their intimate partner, a close friend, and a different-sex stranger. Laboratory and real-world IPA were uniquely associated with altered activity within and connectivity between cortical midline structures that subserve social cognition and the computation of value. Men's IPA most corresponded to lower posterior cingulate reactivity during provocation and women's IPA most corresponded to lower ventromedial prefrontal cortex activity during IPA itself. Actor-partner independence modeling suggested women's IPA may correspond to their male partner's neural reactivity to provocation. Broadly, these findings highlight the importance of self-regulatory functions of the medial cortex and away from effortful inhibition subserved by dorsolateral cortices.

Relationship between stressful life events and cyberbullying perpetration: Roles of fatalism and self-compassion

Few studies have documented the relationship between stressful life events and cyberbullying perpetration, and the mechanisms connecting this link are unknown. Thus, the current study tested the association of stressful life events with cyberbullying perpetration and explored this influencing mechanism further with fatalism and self-compassion tested as a mediator and a moderator respectively. A sample of 1104 Chinese adolescents (50.72% males; mean age = 13.11) volunteered for this study. The results revealed that exposure to stressful life events was positively related to cyberbullying perpetration, and fatalism played a mediation role in this relationship. The moderated mediation model revealed that stronger self-compassion weakened and even interrupted the direct associations of stressful life events with fatalism and cyberbullying perpetration, and further weakened and even interrupted the indirect relationship between stressful life events and cyberbullying perpetration via fatalism. That is, adolescents low in self-compassion were more likely to build fatalistic beliefs and engage in cyberbullying perpetration when they experienced high levels of stressful life events; whereas, stressful life events were not related to increased risk of cyberbullying perpetration among adolescents high in self-compassion.

Prevalence, risk and protective factors of alcohol use disorder during the COVID-19 pandemic in U.S. military veterans

BACKGROUND

There have been reports of increased alcohol consumption during the COVID-19 pandemic in the general population. However, little is known about the impact of the pandemic on the prevalence of alcohol use disorder (AUD), especially in high-risk samples such as U.S. military veterans.

METHODS

Data were analyzed from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative, prospective cohort of 3078 U.S. veterans. Pre-pandemic and 1-year peri-pandemic risk and protective factors associated with incident and chronic probable AUD were examined.

RESULTS

A total of 6.9 % (n = 183) of veterans were classified as chronic probable AUD, 3.2 % (n = 85) as remitted from AUD, and 2.7 % (n = 71) as incident probable AUD during the pandemic; the prevalence of probable AUD in the full sample remained stable -10.1 % pre-pandemic and 9.6 % peri-pandemic. Younger age, greater pre-pandemic alcohol use severity, and COVID-related stressors were associated with incident AUD during the pandemic, whereas higher pre-pandemic household income was associated with lower risk of this outcome. Younger age, combat experience, lifetime substance use disorder, greater drug use severity, lower dispositional optimism, and more COVID-related worries and social restriction stress were associated with higher risk of chronic AUD.

CONCLUSIONS

Nearly 1-in-10 US veterans screened positive for AUD 1-year into the pandemic; however, the pre- and 1-year peri-pandemic prevalence of probable AUD remained stable. Veterans who are younger, have served in combat roles, endorse more COVID-related stressors, and have fewer socioeconomic resources may be at higher risk for AUD during the pandemic.

Overlapping measures or constructs? An empirical study of the overlap between self-control, psychopathy, Machiavellianism and narcissism

Overlap between self-control and dark triad traits (i.e., psychopathy, Machiavellianism, and narcissism) is potentially problematic for efforts to distinguish dimensions associated with elevated risk for antisociality and crime. The aim of the present study is to examine the potential overlap between self-control and psychopathy, Machiavellianism, and narcissism, with a focus on the Brief Self-Control Scale (BSCS) and the Dirty Dozen Dark Triad scale (DD). The sample consisted of 567 youth (M = 15.91 years, SD = 0.99 years, age range = 14-18 years) from Portugal. Exploratory and confirmatory factor analysis results from the pooled set of items of the BSCS and the DD measures revealed that both are valid and reliable measures of their respective constructs. However, consistent with previous research, the narcissism facet of the DD emerged as an independent factor. Our findings suggest that if such an eventual overlap is detected, it would be a question of problematic measures, not constructs.

Alcohol, Trait Anger, and Psychological Flexibility: A Laboratory Investigation of Intimate Partner Violence Perpetration

The I³ Model is a meta-theoretical framework that posits intimate partner violence (IPV) perpetration is the product of three interactive factors: instigators, impellors, and inhibitors. The present study examined the effects of trait anger (an impellor), psychological flexibility (a disimpellor), and alcohol intoxication (a disinhibitor) on IPV perpetration. Participants were 249 heavy drinkers (41% female) who had perpetrated IPV toward their current partner in the past year. Participants completed self-report measures of trait anger and psychological flexibility, were randomly assigned to consume an alcoholic or non-alcoholic beverage, and then engaged in the Taylor Aggression Paradigm (Taylor, 1967) ostensibly against their current partner. Analyses detected a small-to-medium effect for two separate two-way interactions. First, a significant Beverage x Psychological Flexibility interaction was detected. Consistent with the I³ Model, explication analyses revealed that alcohol intoxication predicted higher levels of IPV perpetration in those who reported low, but not high, psychological flexibility (i.e., low disimpellance). Second, although the Beverage x Trait Anger interaction was non-significant, explication analyses revealed that alcohol intoxication predicted higher levels of IPV perpetration among those who reported low, but not high, trait anger (i.e., low impellance). These results have several potential treatment implications among alcohol-consuming clients.

p-Curve analysis of the Taylor Aggression Paradigm: Estimating evidentiary value and statistical power across 50 years of research

The overall reliability or evidentiary value of any body of literature is established in part by ruling out publication bias for any observed effects. Questionable research practices have potentially undermined the evidentiary value of commonly used research paradigms in psychological science. Subsequently, the evidentiary value of these common methodologies remains uncertain. To quantify the severity of these issues in the literature, we selected the Taylor Aggression Paradigm (TAP) as a case study and submitted 170 hypothesis tests spanning over 50 years of research to a preregistered p-curve analysis. The TAP literature (N = 24,685) demonstrated significant evidentiary value but yielded a small average effect size (d = 0.29) and inadequate power (38%). The main effects demonstrated greater evidentiary value, power, and effect sizes than interactions. Studies that tested the effects of measured traits did not differ in evidentiary value or power to those that tested the effects of experimentally manipulated states. Exploratory analyses revealed that evidentiary value, statistical power, and effect sizes have improved over time. We provide recommendations for researchers who seek to maximize the evidentiary value of their psychological measures.

Sexual Violence Perpetration Within Intimate Relationships: An I3 Model Analysis of the Effects of Sexual Violence Victimization and Psychological Flexibility

The I³ Model posits that intimate partner violence (IPV) is determined by the relative strength of instigatory, impellance, and inhibitory factors. Although much research has examined nonsexual IPV, few studies have used the I³ Model to examine sexual IPV. This study investigated the effects of sexual IPV victimization (an impellor) and psychological flexibility (an inhibitor) on sexual IPV perpetration within a dyadic framework. Participants nested within 617 intimate couples completed measures of psychological flexibility and sexual IPV perpetration and victimization. Results showed that Actor IPV victimization was positively and Actor psychological flexibility was negatively associated with Actor IPV perpetration. Among those who experienced low levels of IPV victimization, psychological flexibility inhibited IPV perpetration. This inhibiting effect did not extend to Actors who experienced high levels of IPV victimization. Findings highlight the complex interactions between I³ factors and support continued dyadic examination of IPV perpetration etiology.

The prospective impact of 10-day patron bans on crime in Queensland's largest entertainment precincts

INTRODUCTION

Night-time entertainment precincts (NEP) are the site of a disproportionate amount of alcohol-related violence, injuries and anti-social behaviour. To combat this the Queensland government introduced patron bans in October 2014, giving police the power to exclude individuals from NEPs and preventing patrons from remaining in or entering the designated area or from designated premises for the ban duration. Mandatory identification scanners within licensed venues were also introduced, which are used to enforce patron bans. This study aimed to evaluate the effectiveness of police-issued 10-day patron bans for preventing alcohol-related violence or anti-social behaviour occurring within NEPs during high-alcohol hours.

METHODS

Queensland's largest NEPs; Brisbane central business district, Fortitude Valley and Surfers Paradise central business district; were examined. Time-series autoregressive integrated moving average analyses were used to estimate the influence of 10-day patron bans on police-recorded serious assaults, common assaults and good order offences. Analyses controlled for the introduction of relevant policy and identification scanners.

RESULTS

The number of police-issued patron bans did not significantly predict changes in serious assault, common assault or good order offence trends the weekend following the ban (within the 10-day period).

DISCUSSION AND CONCLUSIONS

The current study was unable to find evidence indicating that 10-day patron bans reduced alcohol-related harms experienced in Queensland's largest NEPs in the short term. Further research needs to be conducted examining other types of patron bans, particularly longer bans issued in other jurisdictions or by licensees, and whether bans change individual's behaviour.

Mindfulness and Cyberbullying Among Chinese Adolescents: The Mediating Roles of Perceived Social Support and Empathy

INTRODUCTION

Previous studies have shown that mindfulness is associated with fewer cyberbullying behaviors in adolescents. The present study investigated the ways in which mindfulness is related to cyberbullying in Chinese adolescents by considering the role of empathy and perceived social support.

METHODS

A total of 1,390 Chinese high school students were recruited for this study. Adolescents' self-reports of mindfulness, cyberbullying, empathy, and perceived social support were used in the analyses.

RESULTS

The results showed our model fitted the data well [χ²/df = 2.413, CFI = 0.968, TLI = 0.958, RMSEA (90% CI) = 0.059 (0.040-0.078)], and revealed empathy and perceived social support partially mediate the relationship between mindfulness and cyberbullying.

CONCLUSION

The results of this study indicate adolescents' mindfulness plays a crucial role on the likelihood of cyberbullying as well as empathy and perceived social support. Improving the mindfulness skills of adolescents should be considered by teachers and parents seeking to decrease cyberbullying.

Validation of a Brief Measure of Aggression for Ecological Momentary Assessment Research: The Aggression-ES-A

Ecological momentary assessment (EMA) holds significant potential within aggression research. It affords researchers the possibility of collecting data in ecological context, in near real time. However, there is a lack of measures of aggression that have been developed and validated for use in EMA contexts. In this study, we report on the validation of a measure specifically designed to address this need: the Aggression-ES-A. Building on a previous pilot study, we evaluate the within- and between-person reliability, nomological net and associations with a validated trait measure of aggression of the Aggression-ES-A in a sample of N = 255 emerging adults from the Zurich Project on Social Development from Childhood to Adulthood (z-proso). Using multilevel confirmatory factor analysis and structural equation modeling, we found support for the factorial validity, reliability, and concurrent validity of the Aggression-ES-A scores. Results support the use of the Aggression-ES-A in EMA studies utilizing community-ascertained samples.

Alcohol-related relationship dissatisfaction: A putative mechanism for intimate partner aggression

Decades of research has identified alcohol use as a contributing cause of intimate partner aggression (IPA) perpetration; however, there have been fewer studies that seek to identify mediators of the relation between alcohol use and IPA perpetration. Building on research showing a positive association between problematic drinking and relationship dissatisfaction and relationship dissatisfaction and IPA, we examined whether relationship dissatisfaction accounted for the relation between problematic drinking and IPA perpetration in couples using statistical modeling that accounted for the interdependence between partners. Our results showed that (a) actor problematic drinking was related to actor psychological and physical IPA perpetration and that this relation was partially explained by actor relationship dissatisfaction, (b) partner problematic drinking was related to actor physical and psychological IPA perpetration and that this relation was partially explained by actor relationship dissatisfaction, and (c) partner problematic drinking was related to actor psychological IPA perpetration and that this relation was partially explained by partner relationship dissatisfaction. Together, our results highlight that when partner interdependence is considered, relationship dissatisfaction could be a potential mechanism of the alcohol-IPA association and provide some evidence for different pathways for psychological and physical aggression.
