Facet-level analysis of the relations between personality and laboratory aggression.

Multiple reviews and meta-analyses have identified the low pole of the Five-Factor Model (FFM) Agreeableness (also called Antagonism) as the primary domain-level personality correlates of aggression across self-report and behavioral methodologies. In the current study, we expand on this literature by investigating the relations between FFM facets and aggressive behavior as measured by laboratory competitive reaction time tasks (CRTTs). Across three samples (total N = 639), we conducted weighted mean analyses, multiple regression analyses, and dominance analyses to determine which FFM facets were the strongest predictors of aggression within and across domains. These analyses suggested that facets of Agreeableness were among the strongest consistent predictors of CRTT aggression, including Sympathy (r = -.21) and Cooperation (r = -.14), but facets from other FFM domains also yielded meaningful relations (e.g., Anger from Neuroticism; r = .17). We conclude by discussing these results in the context of controversies surrounding laboratory aggression paradigms and emphasizing the importance of considering small effect sizes in the prediction of societally harmful behavior like aggression.

Development and Validation of the Praise, Indulgence, and Status Parenting Scale.

The overarching aim of this study was to develop and validate a new scale (i.e., the Praise, Indulgence, and Status Parenting Scale [PISPS]) to measure modern parenting practices and behaviors consistent with instilling ideals of specialness (i.e., the notion that one is special), self-esteem, and status in children. In 2 studies on emerging adults (Study 1: N = 582, M age = 19.46; Study 2: N = 464, M age = 19.58), the PISPS was developed and validated using classical test theory (Study 1) and further refined using item-response theory (Study 2). Results from both studies indicated a 3-factor structure with factors differentially linked with correlates of interest including parenting strategies, self-esteem, narcissism, entitlement, and internalizing symptoms. Study 3 further validated the PISPS in a sample of parents (N = 638, M age = 35.79) reporting on their parenting and their child's emotion regulation and symptoms of psychopathology. Overall, findings support the PISPS, its psychometric properties, and its unique contribution to child symptoms.

Analytic flexibility in laboratory aggression paradigms: Relations with personality traits vary (slightly) by operationalization of aggression.

Competitive reaction time tasks (CRTTs) have been used widely in social science research, but recent criticism has been directed at the flexible quantification strategies used with this methodology. A recent review suggests that over 150 different quantification strategies have been used in this literature, and there is evidence to suggest that different operationalizations can affect the results and interpretations of experiments using CRTTs. In the current investigation, we reanalyze data from four existing samples from two different sites (total N = 600) to examine how the relations between a range of personality traits and aggression vary based on how aggression is operationalized. Our results suggest that there is a modest degree of heterogeneity in effect size and direction for these relations, and that effect size and direction were most consistent for traits more generally related to lab aggression (e.g., psychopathy, low Five-Factor Model agreeableness). In addition, profile matching analyses suggest that different operationalizations yield empirical correlates that are quite similar to one another, even when quantifying absolute rather than relative similarity. These results were consistent across site, methodology, and type of sample, suggesting that these issues are likely generalizable across most labs using CRTTs. We conclude with suggestions for future directions, particularly emphasizing the need for adequately-powered samples, and for researchers to preregister a plan for how CRTT data will be analyzed.

Do beliefs about gender roles moderate the relationship between exposure to misogynistic song lyrics and men's female-directed aggression?

Although independent lines of research have identified misogynistic lyrical content and traditional gender role beliefs as reliable predictors of men's female-directed aggression, more research is needed to understand the extent to which these variables may function in synthesis to potentiate aggression. In the current study, men (N = 193), who completed questionnaires relevant to their conformity to masculine norms and level of hostile and benevolent sexism, were exposed to either misogynistic or neutral lyrics before having the opportunity to shock an ostensible female confederate in a bogus reaction time task that, in effect, measured aggression. Results indicated that misogynistic lyrics and hostile sexism significantly predicted both unprovoked and provoked aggression against a female target. Contrary to expectations, moderating effects of gender role beliefs on the relationship between misogynistic lyrics and men's aggression were not found. Implications are discussed in terms of the costs of misogyny in media for women's lives. Aggr. Behav. 43:123-132, 2017. © 2016 Wiley Periodicals, Inc.

Alcohol-Impaired Driving: The Influence of Adverse Rearing Environments, Alcohol, Cannabis Use, and the Moderating Role of Anxiety.

BACKGROUND: The rate of alcohol-impaired driving (AID) increases during the college years and students who have reported adverse rearing environments appear to be at increased risk for the development of alcohol and drug use behaviors. Alcohol and cannabis are the most commonly used drugs by college students, and these substances are particularly predictive of substance-impaired driving. OBJECTIVES: The present study aimed to investigate whether adverse rearing environment experiences and level of alcohol and cannabis use are related to the frequency of alcohol-impaired driving and whether anxiety might buffer or accelerate this effect. METHODS: Data regarding adversity, drug use, anxiety, and AID were obtained from 1,265 students annually, from first to final year of college, over four waves (Mean Age at wave 1 = 18.5 years). RESULTS: Structural equation modeling supported associations among childhood adversity, alcohol, cannabis, and anxiety symptoms. A significant mediation effect was found such that adversity was predictive of AID via alcohol use and cannabis use. Among men, anxiety symptoms accelerated the path from increased cannabis use and decelerated the path from increased alcohol use to AID frequency. Conclusions/Importance: Childhood adversity is a developmental risk precursor to drug use and AID, whereas anxiety might serve a risk or protective factor to AID, contingent on the drug used.

Developmental Growth Trajectories of Self-Esteem in Adolescence: Associations with Child Neglect and Drug Use and Abuse in Young Adulthood.

Neglectful rearing is linked with young adults' substance use and abuse, though the developmental mechanisms that underlie this association are unclear. The present study examines links between self-esteem growth during adolescence, childhood supervisory versus physical neglect severity, and substance use and abuse in young adulthood. A sample of youth was obtained from the Add Health study (N = 8738; 55.4 %-Female; 20 %-African American, 14.7 %-Hispanic). Growth mixture modeling analyses supported declining, ascending, and stable high self-esteem trajectories. The declining and ascending trajectories reported greater neglect and alcohol abuse (but not use) as well as cannabis use and abuse. The findings suggest that compromised development of self-esteem underlies associations between neglect and substance use and abuse. Preventive interventions may benefit from targeting self-esteem among neglected youth.

Gender Role Discrepancy Stress, High-Risk Sexual Behavior, and Sexually Transmitted Disease.

Nearly 20 million new sexually transmitted infections occur every year in the United States. Traditionally, men have demonstrated much greater risk for contraction of and mortality from STDs perhaps because they tend to engage in a number of risky sexual activities. Research on masculinity suggests that gender roles influence males' sexual health by encouraging risk-taking behavior, discouraging access to health services, and narrowly defining their roles as partners. However, despite the propensity of highly masculine men to engage in high-risk sexual behavior, there is reason to suspect that men at the other end of the continuum may still be driven to engage in similar high-risk behaviors as a consequence of gender socialization. Discrepancy stress is a form of gender role stress that occurs when men fail to live up to the ideal manhood derived from societal prescriptions (i.e., Gender Role Discrepancy). In the present study, we surveyed a national sample of 600 men via Amazon Mechanical Turk to assess perceived gender role discrepancy, experience of discrepancy stress, and the associations with risky sexual behavior and potential contraction of STDs. Results indicated that men who believe they are less masculine than the typical man (i.e., gender role discrepancy) and experience distress stemming from this discrepancy (i.e., discrepancy stress) engage in high-risk sexual behavior and are subsequently diagnosed with more STDs. Findings are discussed in relation to implications for primary prevention strategies.

Masculine discrepancy stress, substance use, assault and injury in a survey of US men.

To understand and ultimately prevent injury and behavioural health outcomes associated with masculinity, we assessed the influence of masculine discrepancy stress (stress that occurs when men perceive themselves as falling short of the traditional gender norms) on the propensity to engage in stereotypically masculine behaviours (eg, substance use, risk taking and violence) as a means of demonstrating masculinity. Six-hundred men from the USA were recruited via Amazon's Mechanical Turk (MTurk) online data collection site to complete surveys assessing self-perceptions of gender role discrepancy and consequent discrepancy stress, substance use/abuse, driving while intoxicated (DWI) and violent assaults. Negative binomial regression analyses indicated significant interactive effects wherein men high on gender role discrepancy and attendant discrepancy stress reported significantly more assaults with a weapon (B=1.01; SE=0.63; IRR=2.74; p=0.05) and assaults causing injury (B=1.01; SE=0.51; IRR=2.74; p<0.05). There was no association of discrepancy stress to substance abuse, but there was a protective effect of gender role discrepancy for DWI among men low on discrepancy stress (B=-1.19, SE=0.48; IRR=0.30; p=0.01). These findings suggest that gender role discrepancy and associated discrepancy stress, in particular, represent important injury risk factors and that prevention of discrepancy stress may prevent acts of violence with the greatest consequences and costs to the victim, offender and society.

Testing a Dual Process Model of Gender-Based Violence: A Laboratory Examination.

The dire impact of gender-based violence on society compels development of models comprehensive enough to capture the diversity of its forms. Research has established hostile sexism (HS) as a robust predictor of gender-based violence. However, to date, research has yet to link men's benevolent sexism (BS) to physical aggression toward women, despite correlations between BS and HS and between BS and victim blaming. One model, the opposing process model of benevolent sexism (Sibley & Perry, 2010), suggests that, for men, BS acts indirectly through HS to predict acceptance of hierarchy-enhancing social policy as an expression of a preference for in-group dominance (i. e., social dominance orientation [SDO]). The extent to which this model applies to gender-based violence remains untested. Therefore, in this study, 168 undergraduate men in a U. S. university participated in a competitive reaction time task, during which they had the option to shock an ostensible female opponent as a measure of gender-based violence. Results of multiple-mediation path analyses indicated dual pathways potentiating gender-based violence and highlight SDO as a particularly potent mechanism of this violence. Findings are discussed in terms of group dynamics and norm-based violence prevention.

Man enough? Masculine discrepancy stress and intimate partner violence.

Research on gender roles suggests that men who strongly adhere to traditional masculine gender norms are at increased risk for the perpetration of violent and abusive acts toward their female intimate partners. Yet, gender norms alone fail to provide a comprehensive explanation of the multifaceted construct of intimate partner violence (IPV) and there is theoretical reason to suspect that men who fail to conform to masculine roles may equally be at risk for IPV. In the present study, we assessed effect of masculine discrepancy stress, a form of distress arising from perceived failure to conform to socially-prescribed masculine gender role norms, on IPV. Six-hundred men completed online surveys assessing their experience of discrepancy stress, masculine gender role norms, and history of IPV. Results indicated that masculine discrepancy stress significantly predicted men's historical perpetration of IPV independent of other masculinity related variables. Findings are discussed in terms of potential distress engendered by masculine socialization as well as putative implications of gender role discrepancy stress for understanding and intervening in partner violence perpetrated by men.

Liquid courage or liquid fear: alcohol intoxication and anxiety facilitate physical aggression.

Participants were 138 male social drinkers between 18 and 30 years of age from a university community in the southeastern United States in 2000. Trait and state anxiety was measured using the Trait Anxiety Inventory and the Facial Action Coding System, respectively. Participants consumed an alcoholic or nonalcoholic control beverage and completed a shock-based aggression task. Regression analysis indicated that alcohol-facilitated elevations in anxiety mediated the relation between alcohol consumption and aggression and that trait anxiety and physical provocation moderated this effect. Implications and limitations of this study are noted and future research directions are suggested.

Unprovoked aggression: effects of psychopathic traits and sadism.

Psychopathic individuals engage in the most violent and cold-blooded acts of aggression. In the laboratory, psychopathy traits have been linked to the commission of unprovoked aggression. The purpose of this study was to assess affective motives that may underlie the relationship between psychopathy and unprovoked aggression. One hundred thirty-seven men viewed a series of photographs depicting violent imagery, completed a lexical decision task designed to assess state affect, and competed in a laboratory-based aggression paradigm. Results indicated that participants who responded faster to happiness words after viewing violent imagery (i.e., sadistic) were significantly more likely to engage in unprovoked aggression. Additionally, Factor 1 psychopathy (emotional detachment) predicted increased probability of unprovoked aggression; however, this relationship was not mediated by sadism. Rather, Factor 1 and sadism each independently predicted unprovoked aggression. The implications of the present data suggest that the type of violence evinced may inform the risk for perpetration of future acts. That is, the individual who demonstrates unprovoked violence may be more likely to employ aggressive tactics across situational contexts than the individual who demonstrates only impulsive acts of hostile/reactive aggression.

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.

Narcissism and unprovoked aggression.

It is widely accepted that narcissists become aggressive when they experience ego-threat. However, there is surprisingly little empirical research on the relationship between narcissism and aggression. Equivocal findings suggest that aggression in narcissists either occurs only in response to provocation, or regardless of provocation. One-hundred and thirty-seven collegiate men completed the Narcissistic Personality Inventory followed by a sham aggression paradigm, which afforded them the opportunity shock, or refrain entirely from shocking an ostensible opponent confederate. Participants were identified as "unprovoked aggressors," "retaliatory aggressors," or "nonaggressors" contingent on when and if they chose to administer electrical shocks to the confederate. Results indicated that participants who were high on narcissistic traits were more likely to be unprovoked aggressors than their low narcissism counterparts. Results are discussed in relation to threatened egotism theory and call for more research on narcissism, aggression, and the moderating effect of provocation.

Examining the relations among narcissism, impulsivity, and self-defeating behaviors.

A recent meta-analysis (S. Vazire & D. C. Funder, 2006) suggested that narcissism and impulsivity are related and that impulsivity partially accounts for the relation between narcissism and self-defeating behaviors (SDB). This research examines these hypotheses in two studies and tests a competing hypothesis that Extraversion and Agreeableness account for this relation. In Study 1, we examined the relations among narcissism, impulsivity, and aggression. Both narcissism and impulsivity predicted aggression, but impulsivity did not mediate the narcissism-aggression relation. In Study 2, narcissism was related to a measure of SDB and manifested divergent relations with a range of impulsivity traits from three measures. None of the impulsivity models accounted for the narcissism-SDB relation, although there were unique mediating paths for traits related to sensation and fun seeking. The domains of Extraversion and low Agreeableness successfully mediated the entire narcissism-SDB relation. We address the discrepancy between the current and meta-analytic findings.

The relationship between pain tolerance and trait aggression: effects of sex and gender role.

The literature on pain and aggression has indicated that pain elicits aggression. However, research has generally examined pain as a situational variable and focused less on the dispositional ability of an individual to tolerate pain. The dearth of research on pain tolerance and aggression appears to contradict the existing theory on the aggression-eliciting effect of pain, in that studies have found a positive relationship between pain tolerance and aggression. The purpose of this study was to determine whether the relationship between pain tolerance and aggression is moderated by sex and whether the positive relationship could be explained by masculine gender role conformity. A sample of 195 collegiate men and women completed trait measures and a laboratory assessment of pain tolerance. Results indicated that correlations between pain tolerance and trait aggression were significant and positive for men but not women. However, when men's conformity to masculine gender role was controlled for, the relationship between pain tolerance and trait aggression was nil and nonsignificant. Results are discussed in reference to socialization and maintenance of masculine status.

Alcohol consumption and perceived sexual coercion: effects of gender and personality determinants.

Alcohol intoxication is a risk factor for being a perpetrator or victim of sexual coercion. Environmental factors (e.g., misperception of social cues), as well as dispositional factors (e.g., personality, gender), are believed to play an important role in linking alcohol consumption and sexual coercion. Sixty-three participants, chosen on the basis of being high or low on scales of hypermasculinity (men) or hyperfemininity (women), were randomly assigned to either an alcohol or nonalcohol condition. After viewing a video of an ambiguous heterosexual interaction, participants responded to questions assessing their accuracy of recall of cues from the interaction, positive bias in their recall of cues, and expectancies regarding 1) the future sexual behavior of the characters in the video and 2) their own conduct if they were in a similar situation. Alcohol was negatively related to accuracy in recall and positively related to the belief that the characters in the video would engage in sexual intercourse (both volitionally and forced). Gender was also important as women were less accurate in recalling cues and intoxicated women evinced a positive bias for cue recall. Traits of hypermasculinity and hyperfemininity were not robust predictors. Hypermasculine men did, however, endorse a substantially higher likelihood that they would have sexual intercourse if in a similar situation. Findings are placed in the context of potential preventive interventions.

Masculine Discrepancy Stress, Emotion-Regulation Difficulties, and Intimate Partner Violence.

Research suggests that masculine socialization processes contribute to the perpetration of intimate partner violence (IPV) by men. Although this research has traditionally focused on men who strongly adhere to traditional gender norms, men who negatively evaluate themselves as falling short of these norms (a construct termed masculine discrepancy stress) have proven to be at increased risk of IPV perpetration. Likewise, men experiencing problems with emotion regulation, a multidimensional construct reflecting difficulties in effectively experiencing and responding to emotional states, are also at risk of IPV perpetration. In the present research, we tested the hypothesis that the link between discrepancy stress and IPV perpetration is mediated via difficulties in emotion regulation. Three hundred fifty-seven men completed online surveys assessing their experience of discrepancy stress, emotion-regulation difficulties, and history of IPV perpetration. Results indicated that discrepancy-stressed men's use of physical IPV was fully mediated by emotion-regulation difficulties. In addition, emotion-regulation difficulties partially mediated the association between discrepancy stress and sexual IPV. Findings are discussed in terms of the potential utility of emotion-focused interventions for modifying men's experience and expression of discrepancy stress and reducing perpetration of IPV.

Psychopathy Traits and Violent Assault Among Men With and Without History of Arrest.

Although research suggests that the antisocial behavior (ASB) facet of psychopathy generally carries the greatest predictive power for future violence, these findings are drawn primarily from forensic samples and may reflect criterion contamination between historical violence and future violence perpetration. Likewise, these findings do not negate the association of other psychopathy facets to violence or their role in the development of violence, nor do they offer practical utility in the primary prevention of violence. There are a number of empirical and theoretical reasons to suspect that the callous affect (CA) facet of psychopathy may demonstrate stronger statistical association to violence in nonforensic populations. We tested the association of CA to severe acts of violence (e.g., assault with intent to harm, injure, rape, or kill) among men with and without history of arrest ( N = 600) using both the three- and four-facet models of psychopathy. CA was robustly associated with violence outcomes across the two groups in the three-facet model. When testing the four-facet model, CA was strongly associated with violence outcomes among men with no history of arrest, but only moderately associated with assaults causing injury among men with history of arrest. These results are consistent with data from youth populations that implicate early emotional deficits in later aggressive behavior and suggest CA may help to identify individuals at risk for violence before they become violent. Implications for the public health system and the primary prevention of violence are discussed.

Determinants of anger and physical aggression based on sexual orientation: an experimental examination of hypermasculinity and exposure to male gender role violations.

The present study examined the effects of hypermasculinity and exposure to male gender role violations on antigay anger and aggression. Participants were 148 heterosexual men who were randomly assigned to view either a male-male or a male-female erotic video. Participants completed a measure of hypermasculinity and anger was assessed before and after viewing the erotic video. A laboratory paradigm was then used to measure physical aggression toward a gay or heterosexual man. Hypermasculinity predicted greater increases in anger among men who viewed male-male erotica relative to men who viewed male-female erotica. Hypermasculinity also predicted higher levels of physical aggression toward a gay, relative to a heterosexual, man, but only after viewing male-male erotica. Findings were discussed within the context of the General Aggression Model.
