Study protocol for a randomized controlled trial of RealConsent2.0: a web-based intervention to promote prosocial alcohol-involved bystander behavior in young men.

BACKGROUND: Sexual violence (SV) is a significant, global public health problem, particularly among young adults. Promising interventions exist, including prosocial bystander intervention programs that train bystanders to intervene in situations at-risk for SV. However, these programs suffer from critical weaknesses: (1) they do not address the proximal effect of alcohol use on bystander decision-making and (2) they rely on self-report measures to evaluate outcomes. To overcome these limitations, we integrate new content specific to alcohol use within the context of prosocial bystander intervention into an existing, evidence-based program, RealConsent1.0. The resulting program, RealConsent2.0, aims to facilitate bystander behavior among sober and intoxicated bystanders and uses a virtual reality (VR) environment to assess bystander behavior in the context of acute alcohol use. METHODS: This protocol paper presents the design of a randomized controlled trial (RCT) in which we evaluate RealConsent2.0 for efficacy in increasing alcohol- and non-alcohol-involved bystander behavior compared to RealConsent1.0 or to an attention-control program ("Taking Charge"). The RCT is being implemented in Atlanta, GA, and Lincoln, NE. Participants will be 605, healthy men aged 21-25 years recruited through social media, community-based flyers, and university email lists. Eligible participants who provide informed consent and complete the baseline survey, which includes self-reported bystander behavior, are then randomized to one of six conditions: RealConsent2.0/alcohol, RealConsent2.0/placebo, RealConsent1.0/alcohol, RealConsent1.0/placebo, Taking Charge/alcohol, or Taking Charge/placebo. After completing their assigned program, participants complete a laboratory session in which they consume an alcohol (target BrAC: .08%) or placebo beverage and then engage in the Bystanders in Sexual Assault Virtual Environments (BSAVE), a virtual house party comprising situations in which participants have opportunities to intervene. Self-reported bystander behavior across alcohol and non-alcohol contexts is also assessed at 6- and 12-months post-intervention. Secondary outcomes include attitudes toward, outcome expectancies for, and self-efficacy for bystander behavior via self-report. DISCUSSION: RealConsent2.0 is the first web-based intervention for young men that encourages and teaches skills to engage in prosocial bystander behavior to prevent SV while intoxicated. This is also the first study to assess the proximal effect of alcohol on bystander behavior via a VR environment. TRIAL REGISTRATION: Clinicaltrials.gov, NCT04912492. Registered on 05 February 2021.

Impulsivity and Reactive-Proactive Aggression as Mechanisms of Alcohol-Related Sexual Intimate Partner Violence Perpetration among Romantic Partners.

Background: Sexual intimate partner violence (S-IPV) commonly occurs within the contexts of committed romantic relationshops. Prior research has demonstrated the existence of a robust link between alcohol use and S-IPV. Despite this, few research studies have explored the etiological underpinnings of alcohol-related S-IPV perpetration, specifically. The present study examines the role of several key factors (i.e., problematic drinking, negative and positive urgency, proactive and reactive aggression) on S-IPV perpetration. Methods: Participants were 337 heavy drinking men and women in intimate relatinships who reported perpetrating some form of IPV toward their current partner within the past-year. A moderated-mediation model was used to determine how the key study variables interacted to predict S-IPV perpetration. Results: Results indicated that problematic drinking was positively correlated with both negative urgency and positive uregency. Findings also revealed that negative urgency, positive urgency, proactive aggression, and reactive aggression were all positively related to S-IPV perpetration. The indirect relationship between problematic drinking and S-IPV perpetration was mediated by positive urgency. Additionally, a significant main effect of proactive aggression on S-IPV perpetration was also detected. Conclusions: These findings suggest that impulsivity, specifically positive urgency, and proactive aggression may be under-appreciated constructs within the existing sexual aggression literature, and future research examining these variables as mechanisms explaining the association between the alcohol and S-IPV is warranted.

Emotion differentiation and intimate partner violence: Effects of provocation and alcohol intoxication.

OBJECTIVE: This study investigated the impact of relational provocation on intimate partner violence (IPV) perpetration as a function of alcohol intoxication and individuals' emotion differentiation (ED; i.e., the ability to differentiate between positive and negative emotions). We hypothesized that provocation and acute intoxication would be associated with lower ED, such that individuals would demonstrate lower ED following provocation and while intoxicated. We also hypothesized an intoxication-by-ED interaction, such that only individuals who were intoxicated and undifferentiated would perpetrate IPV. METHOD: Two hundred fifty community-based adults completed an aggression paradigm ostensibly with their romantic partners where they were randomly assigned to an alcohol or no-alcohol condition. Participants' ED across positive and negative subscales was calculated at baseline (Time 1), postprovocation and intoxication (Time 2), and postbehavioral aggression (Time 3). IPV was operationalized as the strength and duration of shocks issued to their partner during the aggression paradigm. RESULTS: Both sober and intoxicated participants experienced lower ED following provocation, suggesting a main effect of provocation but no main effect of intoxication. There was a significant alcohol-by-ED interaction in the predicted direction. For intoxicated participants, low ED was associated with greater IPV perpetration. For sober participants, low ED was associated with less IPV perpetration. CONCLUSIONS: Consistent with hypotheses, low ED is associated with greater IPV perpetration among intoxicated individuals. In contrast to prior research, low ED was associated with less IPV perpetration among sober individuals. Alcohol-related cognitive impairments may increase the likelihood of IPV perpetration by disrupting the ED process that may otherwise inhibit impulsive aggression.

Examining the Moderating Role of Heavy Drinking Behaviors and Precarious Masculinity on Sexual Aggression Among Young Adult Men.

OBJECTIVE: Men's heavy drinking behaviors are related to their engagement in sexual aggression and may be amplified by other factors, such as precarious masculinity (i.e., perceiving masculinity as tenuous in nature). Yet, researchers' understanding of how alcohol consumption, in combination with precarious masculinity, may increase risk of sexual aggression is lacking. The goal of this study was to assess if precarious masculinity moderated the relationship between men's heavy drinking and their sexual aggression. METHOD: Young adult men (958 men, M age = 21.1 years, SD = 3.1) completed a web-administered questionnaire assessing sexual aggression, heavy drinking, and precarious masculinity. RESULTS: We ran a logistic regression examining the association between heavy drinking, precarious masculinity, and their interactive effect on men's engagement in sexual aggression. Heavy drinking (odds ratio [OR] = 1.17) and precarious masculinity (OR = 1.73) were independently and positively associated with men's sexual aggression; however, the interaction was not significant. CONCLUSIONS: In line with prior research, men's heavy drinking behaviors continue to be positively associated with sexual aggression. Building on masculinity literature, men viewing their masculinity as precarious and vulnerable appears to be associated with sexual aggression, potentially because engaging in sexual aggression can offset men's masculinity insecurities. Collectively, results suggest that both alcohol consumption and masculinity should be targeted in sexual assault prevention programs.

Sexual Victimization Among Sexual and Gender Minoritized Groups: Recent Research and Future Directions.

PURPOSE OF THE REVIEW: Sexual victimization is a significant public health concern. Compared to heterosexual and cisgender peers, sexual and gender minoritized (SGM) individuals are at elevated risk for sexual victimization. Prominent theories suggest that this risk is due in part to the stigma SGM individuals face when navigating heteronormative cultures. The goal of this article is to review the prevalence, risk factors, and consequences of sexual victimization in SGM individuals. RECENT FINDINGS: Studies continue to show that SGM individuals-bisexual and/or gender minoritized in particular-are at higher risk for sexual victimization. Little work has focused on risk factors, though recent research continues to highlight post-victimization disparities among SGM individuals. Emerging studies also point to theoretically informed factors that may influence victimization risk and recovery, including sexual and gender-related stigma. To inform prevention and intervention efforts, future research would benefit from streamlining assessment, methodology, and dissemination practices.

The effects of alcohol and marijuana co-use patterns on intimate partner aggression perpetration.

Alcohol and marijuana are two of the most widely used substances in the U.S, with rates of alcohol and marijuana co-use increasing in recent years. Despite this increase, little is known about the effects of alcohol and marijuana co-use patterns (e.g., simultaneous, concurrent) on intimate partner aggression (IPA) perpetration. The purpose of the current study was to examine differences in IPA among simultaneous and concurrent alcohol and marijuana use groups and an alcohol-only group. Participants were 496 individuals (57% identifying as a woman) recruited nationally in April 2020 via Qualtrics Research Services who reported being in a current relationship and recently consuming alcohol. Individuals completed an online survey that included demographics, measures of COVID-19 stress, alcohol and marijuana use, and physical and psychological IPA perpetration. Based on survey responses, individuals were categorized as belonging to the alcohol use only group (n = 300), the concurrent alcohol and marijuana use group (n = 129), or the regular simultaneous alcohol and marijuana use group (n = 67). Due to inclusion criteria, there was no marijuana use only group. Individuals with regular simultaneous or concurrent alcohol and marijuana co-use reported more frequent physical and psychological IPA perpetration compared to those who only used alcohol. Neither physical nor psychological IPA perpetration frequency differed between individuals who reported regular simultaneous versus concurrent alcohol and marijuana co-use. Results suggest that alcohol and marijuana co-use in general, and not the specific pattern of use, is associated with an increased likelihood of IPA perpetration.

Dyadic effects of minority stress and problematic alcohol use on sexual intimate partner violence in same sex couples.

Little is known about the factors that facilitate the perpetration of sexual violence within the context of same-sex romantic relationships (sexual intimate partner violence perpetration [S-IPV]). The present study sought to identify the effects of external and internal minority stress and problematic drinking on perpetration of S-IPV within a dyadic framework. A community-based sample of 137 sexual and gender minority (SGM) couples (N = 274; 59 male assigned at birth and 78 female assigned at birth couples) completed self-report surveys about minority stressors, alcohol use, and S-IPV perpetration. Multilevel logistic regression analyses were conducted within an actor-partner interdependence framework. This approach accounted for both actor effects (e.g., how much one's S-IPV perpetration is predicted by their own risk factors) and partner effects (e.g., how much one's S-IPV perpetration is influenced by their partner's risk factors). Both Actor external minority stress and internal minority stress were positively associated with Actor S-IPV perpetration. Actor problematic drinking was not associated with Actor S-IPV perpetration; however, Partner problematic drinking was positively associated with Actor S-IPV perpetration. Observed effects were robust above the addition of other risk factors. This research innovatively extricates S-IPV perpetration from other forms of IPV and indicates that Actor minority stress and Partner problematic drinking increase S-IPV likelihood. Results serve as a starting point for development of etiological models to inform the design of culturally-informed interventions to reduce S-IPV among SGM couples.

COVID Stress, socioeconomic deprivation, and intimate partner aggression during the COVID-19 pandemic.

BACKGROUND: Intimate partner aggression (IPA) is a prevalent public health concern that is associated with multiple negative consequences. Rates of IPA in the U.S. have increased since the onset of the Coronavirus Disease 2019 (COVID-19) pandemic, likely due to stress associated with the pandemic. Socioeconomic deprivation is associated with COVID-19 outcomes as well as IPA. However, whether socioeconomic deprivation interacts with COVID-19 stress in predicting IPA remains unclear. METHODS: Using a sample of 510 individuals recruited via Qualtrics Research Services in April 2020, the present study tested whether socioeconomic deprivation moderates the association between COVID-19 stress and IPA perpetration and victimization. Participants completed a questionnaire battery that included measures of COVID-19 stressors and physical and psychological IPA perpetration and victimization. In addition, participants reported their residential zip codes, which were subsequently matched with scores on the Social Deprivation Index, a composite measure of seven demographic variables from the 5-year American Community Survey. RESULTS: Sequential generalized linear models in Mplus Version 8.7 showed that the effects of COVID-19 stress on physical IPA perpetration and psychological IPA victimization can be best understood through its interactive effects with socioeconomic deprivation. Higher COVID-19 stress was associated with higher levels of physical IPA perpetration and psychological IPA victimization when socioeconomic deprivation was low but not when socioeconomic deprivation was high. Importantly, however, overall rates of IPA were higher among individuals with higher socioeconomic deprivation than among individuals with lower socioeconomic deprivation, regardless of the amount of COVID-19 stress they experienced. CONCLUSIONS: The present analyses implicate COVID-19 stress as a critical correlate of IPA and show that the association between this stress and physical IPA perpetration and psychological IPA victimization may be particularly salient among individuals who live in areas of lower socioeconomic deprivation. Furthermore, our results clearly pinpoint the detrimental effects of socioeconomic deprivation more broadly, showing that individuals who live in more deprived areas tend to have high levels of IPA regardless of their level of COVID-19 stress. These findings call for public health policies at the community and societal level that target not only COVID-related stress but also the impacts of socioeconomic inequality.

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.

Intimate Partner Aggression During the COVID-19 Pandemic: Associations With Stress and Heavy Drinking.

Objective: This study aimed to test empirically whether (1) the local impact of the COVID-19 pandemic was associated with increases in intimate partner aggression (IPA) and heavy drinking, and (2) heavy drinking moderated the association between COVID-19 stress and IPA perpetration. Method: Participants were 510 individuals (approximately 50% who endorsed a sexual or gender minority identity) recruited via Qualtrics Research Services in April 2020, during the height of shelter-in-place (SiP) restrictions across the United States. They completed a questionnaire battery that included measures of COVID-19 stressors, physical and psychological IPA perpetration, and heavy drinking. Results: Rates of physical and psychological IPA perpetration significantly increased after implementation of SiP restrictions which aimed to mitigate the transmission of COVID-19. COVID-19 stress was significantly and positively associated with physical and psychological IPA perpetration; however, COVID-19 stress was positively associated with physical IPA perpetration among non-heavy drinking, but not heavy drinking, participants. Conclusions: Drawn from a large sample of participants of diverse sexual identities, findings tentatively implicate COVID-19 stress as a critical correlate of IPA perpetration and suggest that "low risk" individuals (i.e., non-heavy drinkers) should not be overlooked. These data provide preliminary support for the usefulness of public health polices and individual-level interventions that target stress, heavy drinking, and their antecedents.

Sexual Victimization, Self-Efficacy to Refuse Sex While Drinking, and Regretting Alcohol-Involved Sex among Underserved Youth in Kampala, Uganda.

The purposes of this study were to determine whether youth who have experienced sexual victimization (SV) have lower self-efficacy to refuse sex and to identify intervention strategies for rape survivors to mitigate further health-risks and harm. Cross-sectional data from the 2014 Kampala Youth Survey (n = 1134) of youth aged 12 to 18 years recruited from Uganda Youth Development Link drop-in centers were used to conduct the analyses. Multivariable statistics were computed to determine the correlates (i.e., sex, education, homelessness, problem drinking, and SV) for (1) self-efficacy to refuse sex, (2) self-efficacy to refuse sex while drinking, and (3) regretting sex due to alcohol use. Among participants, 16.9% reported SV (79% were female and 21% were male). In the final adjusted model, self-efficacy to refuse sex while drinking was only associated with homelessness (OR: 0.52; 95% CI: 0.36, 0.74). Previous SV was not associated with lower self-reports of self-efficacy to refuse sex compared to those who had not experienced SV. Additionally, SV was not associated with increased reports of regrets for sex attributed to alcohol use. Alcohol prevention strategies for the most at-risk youth, including homeless youth, are warranted to improve self-efficacy to refuse sex among youth living in the slums of Kampala.

A laboratory study of the effects of men's acute alcohol intoxication, perceptions of women's intoxication, and masculine gender role stress on the perpetration of sexual aggression.

BACKGROUND: Although research has established an association between alcohol use and sexual assault, few studies have examined how characteristics of the perpetrator may influence sexual aggression depending upon whether alcohol is consumed by the perpetrator and/or the victim. This laboratory-based investigation was designed to disentangle the effects of individual differences in masculine gender role stress (MGRS) and the perpetration of sexual aggression as a function of (1) men's acute alcohol intoxication and (2) whether a woman was consuming alcohol or not. METHOD: A community sample of 156 men participated in two laboratory sessions, during which they completed a self-report measure of MGRS (Session 1) and a modified version of the sexual imposition paradigm after consuming an alcoholic or non-alcoholic beverage (Session 2). In this paradigm, participants and a male friend were told that an ostensible female participant had consumed or not consumed alcohol. They were also told that she did not wish to view sexual content. Participants were then provided the opportunity to make the female confederate view a sexually or non-sexually explicit film. Sexual aggression was operationalized by selection of the sexually explicit film. RESULTS: A hierarchical logistic regression showed that men higher in MGRS who were intoxicated were (1) more likely than sober men to select the sexually explicit film when the woman was intoxicated and (2) less likely than sober men to select the sexually explicit film when the woman was sober. CONCLUSIONS: These findings suggest that the perpetration of sexual aggression is most likely among men with higher MGRS when there is concordance in drinking (i.e., when either the man and woman are both drinking or are both not drinking).

Cognitive and Affective Mediators of Alcohol-Facilitated Intimate Partner Aggression.

This multisite study examined whether aggressive cognitions and facial displays of negative affect and anger experienced during provocation mediated the association between alcohol intoxication and intimate partner aggression (IPA). Participants were 249 heavy drinkers (148 men, 101 women) with a recent history of IPA perpetration. Participants were randomly assigned to an Alcohol or No-Alcohol Control beverage condition and completed a shock-based aggression task involving apparent provocation by their intimate partner. During provocation, a hidden camera recorded participants' facial expressions and verbal articulations, which were later coded using the Facial Action Coding System and the Articulated Thoughts in Simulated Situations paradigm. Results indicated that the positive association between alcohol intoxication and partner-directed physical aggression was mediated by participants' aggressive cognitions, but not by negative affect or anger facial expressions. These findings implicate aggressogenic cognitions as a mediating mechanism underlying the association between the acute effects of alcohol and IPA perpetration.

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.

Relationship Dissatisfaction, Emotion Regulation, and Physical Intimate Partner Aggression in Heavy-Drinking, Conflict-Prone Couples: A Dyadic Analysis.

Relationship dissatisfaction is a known risk factor for intimate partner aggression (IPA). However, the possible effect of weak emotion regulation skills on this association is unclear, particularly in couples at risk for violence who drink alcohol heavily. This study examined the moderating effect of emotion regulation on the association between relationship dissatisfaction and physical IPA perpetration within a dyadic framework. Participants were 583 heavy drinking couples (N = 1,166) with a recent history of psychological and/or physical IPA recruited from two metropolitan cities in the United States. Multilevel models were used to examine effects within an actor-partner interdependence framework. Gender, Actor dissatisfaction, and Actor and Partner emotion regulation were associated with greater physical IPA perpetration. Actor relationship dissatisfaction predicted significantly greater physical IPA perpetration in Actors characterized by weak versus strong emotion regulation. Furthermore, partner relationship dissatisfaction predicted significantly increased physical IPA perpetration in Actors reporting weak, versus strong, emotion regulation. Gender did not significantly interact with model variables. Utilizing the I3 metatheoretical model of IPA within a dyadic framework, results provide insight into the interactive effects of relationship dissatisfaction and emotion regulation deficits on physical IPA perpetration, particularly in those individuals already at risk for perpetration.

Empathy Is Not Enough: The Inhibiting Effects of Rape Myth Acceptance on the Relation Between Empathy and Bystander Intervention.

Many bystander training programs aim to build empathy and decrease false and often prejudicial beliefs about rape and its occurrence (i.e., rape myth acceptance) to encourage prosocial bystander intervention. However, little empirical research has examined the association between these constructs. The aim of the present study was to examine the effect of rape myth acceptance on the relation between both (a) the ability to experience and share the emotions of others (i.e., emotional empathy) and (b) the ability to understand the emotions of others (i.e., cognitive empathy), and bystander decision-making and intentions to intervention. In Study 1, 154 undergraduate men completed measures of empathy, rape myth acceptance, and bystander decision-making. Findings demonstrated that emotional empathy was associated with more perceived pros for intervention among men with low, but not high, levels of rape myth acceptance. In Study 2, 185 undergraduate men and 210 undergraduate women completed similar measures as in Study 1, with the addition of a measure on bystander intentions to intervene. Results detected a conditional indirect effect of emotional and cognitive empathy on bystander intentions to intervene via the perception that there are more pros than cons to intervention. Findings suggest that empathic individuals may weigh helping a potential victim (i.e., pro) over hurting their own self-image (i.e., con). However, this process is inhibited among men who endorse greater rape myths, likely because they are inhibited from intervening at various steps of the decision-making model. Collectively, these results highlight the importance of targeting both empathy and rape myth acceptance to encourage prosocial bystander intervention.

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.

Correlates of Men's Bystander Intervention to Prevent Sexual and Relationship Violence: The Role of Masculine Discrepancy Stress.

Extant literature suggests that men may be less likely than women to engage in prosocial bystander behavior to interrupt sexual and relationship violence. However, there has been little consideration of the influence of masculine gender role discrepancy and masculine discrepancy stress (i.e., stress that occurs when men perceive themselves as falling short of traditional gender norms) on men's bystander beliefs and behaviors. The current study fills an important gap in the literature by assessing the influence of masculine gender role discrepancy and masculine discrepancy stress on a range of prosocial bystander behaviors through their influence on the bystander decision-making process. Participants were 356 undergraduate men recruited from two different Southeastern U.S. universities who completed online surveys assessing self-perceptions of gender role discrepancy, consequent discrepancy stress, bystander decision-making, and bystander behavior in sexual and relationship violence contexts. Path models indicated significant conditional indirect effects of masculine gender role discrepancy on proactive bystander behaviors (i.e., behaviors related to making a plan in advance of being in a risky situation) and bystander behavior in drinking situations across levels of masculine discrepancy stress. Specifically, men who believed that they are less masculine than the typical man reported more pros to intervention in sexual and relationship violence than cons, and thus reported intervening more, but only if they were high in masculine discrepancy stress. Findings suggest that bystander intervention programs should explicitly address and challenge rigid expectations of what it means to be "manly" to transform gender expectations perpetuating sexual and relationship violence.

Male Role Norms, Heavy Drinking, and Bystander Behavior for Sexual Aggression.

Bystander training programs have proliferated on college campuses to prevent alcohol and non-alcohol-related sexual aggression. However, many programs fail to address the effects of a bystander's alcohol use on intervention. This is not surprising due to the limited research examining this association. To this end, the present study examined how heavy drinking and a known correlate of intervention, men's adherence to traditional masculinity, are jointly and independently associated with bystander behavior in drinking contexts. Participants were 148 community men between the ages of 21 and 30 who completed measures of heavy drinking, adherence to traditional male role norms, and prior bystander behavior in drinking contexts aimed at helping friends and strangers. Hierarchical linear regressions demonstrated that adherence to the belief that men should attain social status was associated with more frequent bystander behavior for friends, whereas adherence to the belief that men should avoid stereotypical feminine activities was associated with less frequent bystander behavior for friends. In addition, the relation between adherence to the belief that men should avoid stereotypical feminine activities and bystander behavior for friends was significant and negative among heavy drinkers but not among non-heavy drinkers. Findings suggest that men who avoid stereotypical feminine activities may be most inhibited from intervening to help friends in party contexts if they are heavy, compared with non-heavy, drinkers. These men are likely consuming alcohol in these party contexts and may benefit from targeted, gender-specific, interventions.

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.
