Sexual assault and rape perpetration by college men: the role of the big five personality traits

Assessment of Sexual Violence Risk Perception in Men Who Have Sex With Men: Proposal for the Development and Validation of "G-Date"

BACKGROUND

Sexual violence (SV) is a significant problem for sexual minorities, including men who have sex with men (MSM). The limited research suggests SV is associated with a host of syndemic conditions. These factors tend to cluster and interact to worsen one another. Unfortunately, while much work has been conducted to examine these factors in heterosexual women, there is a lack of research examining MSM, especially their SV risk perception. Further, MSM are active users of dating and sexual networking (DSN) mobile apps, and this technology has demonstrated usefulness for creating safe spaces for MSM to meet and engage partners. However, mounting data demonstrate that DSN app use is associated with an increased risk for SV, especially given the higher likelihood of using alcohol and other drugs before sex. By contrast, some researchers have demonstrated that DSN technology can be harnessed as a prevention tool for HIV; unfortunately, no such work has progressed regarding SV.

OBJECTIVE

This study aims to (1) use qualitative and quantitative methods to tailor an existing laboratory paradigm of SV risk perception in women for MSM using a DSN mobile app framework and (2) subject this novel paradigm to a rigorous validation study to confirm its usefulness in predicting SV, with the potential for use in future prevention endeavors.

METHODS

To tailor the paradigm for MSM, a team of computer scientists created an initial DSN app (G-Date) and incorporated ongoing feedback about the usability, feasibility, and realism of this tool from a representative sample of MSM. We used focus groups and interviews to assist in the development of G-Date, including by identifying relevant stimuli, developing the cover story, and establishing the appropriate study language. To confirm the paradigm's usefulness, we are conducting an experimental study with web-based and face-to-face participants to determine the content, concurrent, and predictive validities of G-Date. We will evaluate whether certain correlates of SV informed by syndemics and minority stress theories (eg, history of SV and alcohol and drug use) affect the ability of MSM to detect SV risk within G-Date and how paradigm engagement influences behavior in actual DSN app use contexts.

RESULTS

This study received funding from the National Institute on Alcohol Abuse and Alcoholism on September 10, 2020, and ethics approval on October 19, 2020, and we began app development for aim 1 immediately thereafter. We began data collection for the aim 2 validation study in December 2022. Initial results from the validation study are expected to be available after December 2025.

CONCLUSIONS

We hope that G-Date will enhance our understanding of factors associated with SV risk and serve as a useful step in creating prevention programs for this susceptible population.

Men's Self-Reported and Psychophysiological Affective Responses to Sexual Violence and Their Associations with Rape Myths, Personality, and Sexual Traits: A Preliminary Study

Objective: Despite alarming evidence on sexual violence against women, little is known about men's emotional responses to rape and how these may be involved in sexual violence dynamics. Accordingly, our aim was to capture how rape scenarios are emotionally appraised. Methods: The current study evaluated men's (N = 30) self-reported and psychophysiological emotional responses (facial EMG, electrodermal activity) to a rape scene, and contrasted it with their responses to stimuli depicting nonsexual violence and nonviolent male-female interactions. The associations between men's emotional responses and their endorsement of rape myths, personality, and sexual traits were also examined. Results: Findings revealed that the rape scene resulted in higher negative affect, both subjectively and indexed by increased facial EMG (corrugator activity), than the other two stimuli. Additionally, personality traits of neuroticism, lower agreeableness, lower consciousness, psychopathic tendencies, as well as lower sexual inhibition proneness, were all associated with higher subjective sexual arousal toward rape. Conclusions: Findings add to the literature on the putative emotional processes underpinning the appraisal of sexual violence against women.

Reassessing the Confluence Model of Men's Risk for Sexual Aggression

Reassessing the confluence model of men's risk for sexual aggression-the confluence model of sexual aggression has been widely used to study men's risk for perpetrating sexual violence. Over time, researchers have attempted to expand this model to improve its predictive utility. Unfortunately, this work has continued to produce similar results with only slight improvements in prediction at best. One explanation for the inability to enhance the model could be due to changes in the dating landscape and shifts in beliefs about gender roles. Therefore, the current study aims to reassess the confluence model using a more contemporary construct, hostile sexism, in an effort to improve the predictive utility of the confluence model of sexual aggression. Participants were 258 college men recruited from a medium-sized public university in the northeastern United States, using an online participant pool of students who volunteered to participate as part of a requirement for a psychology course. Structural equation modeling using mean- and variance-adjusted weighted least squares estimation indicated that the confluence of hostile sexism and impersonal sex appears to be a better predictor of sexual aggression in comparison to the confluence of hostile masculinity and impersonal sex. The results suggest that replacing hostile masculinity with hostile sexism may produce a model that is better able to predict men's risk for perpetrating sexual aggression. These results can provide insight for future iterations of the confluence model, which may include hostile sexism as a core construct. Attitudes that stem from hostile sexism may be a beneficial target for future interventions designed to decrease the frequency of perpetration.

Dynamic Risk Factors Characterizing Aggressive Sexual Initiation by Female College Students

Past research has supported that community women engage in sexually coercive strategies as a means to initiate sexual intercourse with men. However, at the present state of the knowledge, there is a great lack of scientific information on the psychological characterization of these women. In accordance, the aim of the present study was to characterize the psychopathological and personality profile of a sample of college women reporting sexual initiation by coercive approaches, and to predict membership in the categories of sexually abusive strategies that were used by these women. Findings revealed that 32.7% of women reported to have used some kind of sexually coercive strategy in the past; these women were characterized by the endorsement of more psychopathology symptoms (e.g., depression, anxiety, somatization), and a maladaptive personality style (e.g., neuroticism, impulsiveness, negative trait-affect), in relation to the nonaggressive peers. Also, among the sexually aggressive group, extraversion predicted membership in the category of physical force (i.e., women using physical force to initiate sexual interaction). Findings add to the literature by showing that college women reporting sexually aggressive strategies as a means to initiate sexual intercourse with men present a set of psychopathological and personality features that are qualitatively similar to those features that were previously found to characterize samples of convicted sexual offenders.

The Differential Influence of Drinking, Sensation Seeking, and Impulsivity on the Perpetration of Unwanted Sexual Advances and Sexual Coercion

There are startling rates of sexual coercion across college campuses, underscoring the importance of identifying risk factors and intervening early to prevent perpetration of these unwanted sexual events. The aim of this study was to examine the effects of impulsivity, sensation seeking, and alcohol use on the odds of perpetrating unwanted sexual advances (i.e., forced fondling, kissing, or petting) and sexual coercion (i.e., sexual intercourse through arguments, pressure, or physical force) during the subsequent 6 years. Male participants (N = 901) were part of a 6-year longitudinal study, which explored alcohol use and associated behavioral risks throughout emerging adulthood. Participants provided self-reported surveys across 6 years, starting the summer before their start of college. Using logistic regression models, these analyses examined the main effects and interactions of impulsivity, sensation seeking, and alcohol use, measured during the summer before the start of college, on the odds of perpetrating one or multiple instances of unwanted sexual advances and sexual coercion across the subsequent 6 years. Results indicated that higher levels of sensation seeking and heavier drinking on drinking days during high school contributed to greater odds of being a one-time perpetrator of unwanted sexual advances during the next 6 years. Conversely, impulsivity, but not alcohol use, was associated with greater risk of perpetrating multiple instances of both unwanted sexual advances and sexual coercion. Alcohol use did not significantly moderate the influence of personality on perpetration. These results underscore the importance of early intervention and using impulsivity and sensation seeking to tailor current prevention efforts to decrease the likelihood of sexual coercion perpetration during college.

Predicting rape events: The influence of intimate partner violence history, condom use resistance, and heavy drinking

Sexual aggression perpetration is a public health epidemic, and burgeoning research aims to delineate risk factors for individuals who perpetrate completed rape. The current study investigated physical and psychological intimate partner violence (IPV) history, coercive condom use resistance (CUR), and heavy episodic drinking (HED) as prospective risk factors for rape perpetration. Young adult men (N = 430) ages 21-30 completed background measures as well as follow-up assessments regarding rape events perpetrated over the course of 3 months. Negative binomial regression with log link function was utilized to examine whether these risk factors interacted to prospectively predict completed rape. There was a significant interaction between physical IPV and HED predicting completed rape; men with high HED and greater physical IPV histories perpetrated more completed rapes during follow-up than men with low HED at the same level of physical IPV. Moreover, psychological IPV and coercive CUR interacted to predict completed rape such that men with high coercive CUR and greater psychological IPV histories perpetrated more completed rapes throughout the follow-up period than men with low coercive CUR at the same level of psychological IPV. Findings suggest targets for intervention efforts and highlight the need to understand the topography of different forms of aggression perpetration.

The Association Between Sexually Aggressive Cognitions and Pathological Personality Traits in Men

Sexual aggression, harassment, and sexually aggressive cognitions (victim blaming, sexual entitlement) are serious societal problems. Although research has examined attributes of individuals who engage in overt sexual assault, few studies have focused on individual characteristics of those who perpetuate problematic negative beliefs surrounding sexual assault. This study sought to examine the relationship between pathological personality and sexually aggressive cognitions among 242 community men. Results showed that traits including antagonism, disinhibition, and negative affectivity were associated with sexually aggressive cognitions. These results have implications for understanding sexual aggression and the role personality plays in perpetuating sexually aggressive attitudes.

Five-Factor Model of Personality and Sexual Aggression

Despite several studies have used the five-factor model (FFM) of personality as theoretical background, few studies have been conducted on the topic of the FFM and sexual aggression. This study explored how the big five dimensions and features of emotional adjustment characterize different forms of sexual violence. Twenty-six male students reporting sexual aggression against women (nonconvicted offenders), 32 convicted rapists, and 33 convicted child sexual molesters were evaluated. Participants completed the Five-Factor Inventory (NEO-FFI), the Brief Symptom Inventory (assessing state emotional adjustment), the Sexual Experiences Survey (perpetration form), and the Socially Desirable Response Set Measure. Results showed that individuals convicted for rape and child sexual abuse presented significantly more neuroticism than nonconvicted sexual offenders; child sex molesters presented significantly less openness than rapists and nonconvicted sexual offenders; and nonconvicted sexual offenders presented significantly less conscientiousness than convicted offenders. Regarding emotional adjustment, convicted rapists revealed marked psychopathological features in relation to child molesters. In addition, convicted rapists and nonconvicted sexual offenders presented significantly more hostility than child sexual molesters. Findings suggested that some of the big five traits as well as state features characterizing emotional adjustment may characterize different types of sexual offenders.

Personality and Adolescent School-Based Victimization: Do the Big Five Matter?

Self-control has provided a useful framework for understanding both offending behavior and victimization risk. As a theory of victimization, research has established that low self-control is directly related to victimization risk beyond a range of other factors. This finding raises the issue of whether other personality traits are associated with an increased risk of victimization. Using a sample of ninth-grade adolescents (N = 2,912) from the Rural Substance Abuse and Violence Project (RSVP), we tested whether the Big Five Inventory (BFI) of personality traits predicted adolescent school-based victimization above and beyond low self-control and rival explanations of victimization. The results indicate that, after controlling for risky behaviors, school attachment, and low self-control, neuroticism is positively related to victimization. This finding suggests that examining traits other than low self-control is important to capture fully what makes someone vulnerable to crime. Further, we consider the theoretical and policy implications of the findings.

The Exploitive Mating Strategy of the Dark Triad Traits: Tests of Rape-Enabling Attitudes

The Dark Triad traits have been repeatedly labeled as facilitating an exploitive mating strategy. However, various researchers have repeatedly conflated short-term mating or casual sex with an exploitive mating strategy. In this study using Mechanical Turk participants (N = 252; 142 men, 110 women), we provided a better test of just how sexually exploitive those high on the Dark Triad traits might be by examining how the traits related to rape-enabling attitudes. We examined how each trait may facilitate rape, whether these associations were robust to partialing the variance associated with the Big Five traits and similar in men and women, and showed that one reason why men may be more likely to rape than women is they are characterized by the Dark Triad traits more than women are. In so doing, we test the confluence model of rape that asserts that personality traits similar to the Dark Triad traits act as one pathway to rape.

The Malevolent Side of Revenge Porn Proclivity

This paper presents a novel study, exploring a form of technology facilitated sexual violence (TFSV) known as revenge porn. Despite its emerging prevalence, little is known about the characteristics of revenge porn perpetrators. In the current study, a revenge porn proclivity scale was devised to examine participants' behavioural propensity to engage in revenge porn. One hundred adults, aged 18-54, were recruited online from a community sample. The correlational relationship between revenge porn proclivity and the self-reported endorsement of the Dark Triad, sadism, and ambivalent sexism was examined. Additional proclivity subscales of revenge porn enjoyment and revenge porn approval were also created. The study's main findings revealed a positive correlation between a greater behavioural propensity to engage in revenge porn and higher levels of the Dark Triad and ambivalent sexism. Moreover, endorsement of psychopathy was found to be the only Dark Triad trait that independently predicted revenge porn proclivity. The results suggest that perpetrators of revenge porn may have distinct personality profiles. Limitations and directions for future research are discussed.

Neuroticism and Men's Sexual Coercion as Reported by Both Partners in a Community Sample of Couples

Compared with other forms of intimate partner violence, very little is known about sexual coercion (SC) and its correlates in intact couples from the general population. Among potential dispositional risk factors for SC, neuroticism has been related to various aspects of couple functioning, including psychological and physical partner abuse. Based on theoretical and empirical evidence, we suggest the existence of two maladaptive profiles on the neuroticism dimension and examine the curvilinear association between neuroticism and men's SC. A total of 299 adult couples completed measures of neuroticism and SC perpetrated by the male partner. Descriptive analyses indicated that SC translated mainly into insistence or partner pressure to engage the other in unwanted sexual activities. Results confirmed the hypothesis that both lower and higher levels of men's neuroticism predict higher levels of men's perpetrated SC, while low to moderate levels of neuroticism predict lower levels of men's SC. These findings contribute to the empirical literature on SC in community samples of couples and bear significant clinical implications for the evaluation and treatment of couples experiencing these negative sexual experiences.

The Role of Psychopathy and Exposure to Violence in Rape Myth Acceptance

The main aim of the present study was to specify and test a structural model to examine the relationships between four psychopathy dimensions (Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Antisocial Behavior), childhood exposure to violence, and rape myth acceptance while controlling for gender, age, sample type (prisoner vs. non-prisoner), and relationship status. Participants were a sample of non-offending adults (n = 319) recruited from the University of Security in Poznan, and a sample of prisoners (n = 129) incarcerated in Stargard Szczecinski Prison. Results indicated that the model provided a good fit for the data, and that Callous Affect and childhood exposure to violence had a significant positive effect on attitudes toward rape and rape victims. Theoretical and practical implications of our findings are discussed.

Elaborations on sexual assault on dates among Israeli students: risk, detrimental effect, and resilience factors

The current study of 668 Israeli male and female students examines the prevalence of gendered risk factors for sexual assault (SA) on dates, posttraumatic stress disorder (PTSD) as a detrimental effect of SA, and self-efficacy as resiliency to refuse unwanted sex following SA. Two different sets of risk factors that increased the likelihood of SA on dates emerged from the hierarchical regression. Sexual experience, use of drugs, and private location increased the risk of being SA victims among males, whereas sexual experience, perceived provocative behavior, and alcohol use increased the risk among females. In addition, PTSD and self-efficacy to refuse unwanted sex following SA on dates were predicted by the extent of coercive sexual victimization. PTSD was also predicted by subjective perception of sexual behavior and rape myths, whereas efficacy was predicted by private location. The findings contribute to the literature by showing the contribution of various risk factors to experiencing SA, and by showing SA effect on PTSD and self-efficacy.

Impulsivity and sexual assault in college men

Although impulsivity has been consistently linked to perpetration of sexual aggression, results lack clarity because they do not account for the substantial heterogeneity associated with the construct. The UPPS-P model (Lynam, Smith, Whiteside, & Cyders, 2006), which was proposed to clarify the multidimensional nature of impulsivity, has yet to be applied to sexual aggression. We measured UPPS-P Impulsivity in a sample of male college students who also self-reported on perpetration of sexual aggression. As predicted, impulsivity distinguished perpetrators from nonperpetrators. Perpetrators scored higher than non-perpetrators on Negative Urgency, Positive Urgency, and lack of Premeditation. Results suggest that the impulsivity traits most relevant to sexual aggression are the tendency to act impulsively when experiencing intense emotions (Positive and Negative Urgency) and lack of forethought and planning (lack of Premeditation).
