Factors predictive of sexual violence: Testing the four pillars of the Confluence Model in a large diverse sample of college men

The Relevance of Hypersexuality and Impulsivity in Different Groups of Treatment-Seekers With and Without (Exclusive) Pedophilia

Hypersexuality and impulsivity are regarded as risk factors for sexual offending against children. Studies exploring these factors in undetected men who offended or are at risk of offending are rare. This study aims to investigate hypersexuality and impulsivity in treatment-seeking men with and without a diagnosis of (exclusive) pedophilia who committed child sexual abuse (CSA), consumed child sexual abuse images (CSAI), or feel at risk of offending sexually. Data were obtained from three child abuse prevention projects in Bamberg, Germany. We employed self-report (BIS-11, HBI), objective measures (TSO), and risk assessment tools (STABLE-2007). We computed Bayesian ordinal logit and binomial generalized linear models to explore differences between groups and to predict lifetime CSA and CSAI. Hypersexuality scores were particularly pronounced in patients with exclusive and non-exclusive pedophilia. Patients without pedophilia scored similarly to nonclinical samples. Impulsivity measures did not consistently differ between groups. We could not predict lifetime CSA and CSAI using impulsivity and hypersexuality measures. Sexual rather than general impulsivity seems to be an issue in men with pedophilia. The motivation to offend in patients without pedophilia is discussed.

Motives for Sex and Sexual Perpetration in College Men: An Exploratory Study

OBJECTIVE

Prior research has rarely focused on sexual motives (e.g., motives for having sex) when studying sexual violence perpetration prevention. The current study examined the role of sexual motives alongside other risk factors like alcohol expectancies in predicting sexual violence.

METHOD

We analyzed data from 205 male college students; 36% reported sexual perpetration of some type. Participants completed a series of questionnaires in a randomized order, including: measures of prior sexual perpetration, sexual motives, rape myth acceptance, alcohol expectancies, and a measure of social desirability. Data were analyzed using a series of T-tests and logistic regressions.

RESULTS

With one exception (coping motives), all sexual motives (intimacy, enhancement, self-affirmation, peer approval, and partner approval) were endorsed at higher levels by individuals who perpetrated sexual violence than those who did not (p < .05, Cohen's d = .25-.56). The partner approval motive significantly predicted sexual violence perpetration on its own. The enhancement motive, both independently and in interaction with alcohol expectancies for aggression, predicted sexual violence perpetration. Two other motives, intimacy and self-affirmation, were only significant in interaction with alcohol expectancies for aggression.

CONCLUSION

All sexual motives were endorsed more frequently by those who perpetrated sexual violence than those who did not. Sexual motives had a complex interaction with alcohol expectancies in predicting sexual violence perpetration. The results suggest that intervention programs should emphasize healthy, consensual sexual relationships that do not involve alcohol.

Developmental Trajectories Leading to Hostility Toward Women: A Structural Equation Modeling Study

Hostility toward women is frequently examined as a risk factor for violence against women, but research on its antecedents is sparse. The aim of this study was to explore the developmental and psychological antecedents associated with hostility toward women in a Canadian sample of sexual aggressors of women. Drawing on Malamuth's confluence model of sexual aggression, we developed a multifactorial model of hostility toward women, using structural equation modeling. The results indicate the presence of three trajectories, all starting from childhood victimization and leading to hostility toward women, involving antisocial characteristics, emotional negativity, anxiety, and depression.

Attitudes, Emotions, and Emotion Regulation as Underlying and In-The-Moment Predictors of Men's Intentions to Perpetrate Sexual Assault: An Application of the I3 Model

Sexual assault is a significant problem among young men, and several underlying and in-the-moment factors are associated with this behavior. However, research has not examined how underlying factors may influence men's in-the-moment use of emotion regulation (ER) strategies, emotional experience during sexual situations, or intentions to perpetrate sexual assault. 187 young, single men from the United States who had sex with a woman in the past year completed questionnaires, projected themselves into hypothetical sexual scenarios, and indicated how they would behave when their partner withdrew consent during these scenarios. Participants were grouped into profiles of ER strategy use, which was used as part of a model predicting sexual assault perpetration. Specifically, men with greater hostility toward women were especially likely to use a "low acting with awareness, low resignation" profile, which was associated with greater anger, impulsivity, and intentions to perpetrate. This could be attributed to the increased cognitive load, increased rumination on their partner's refusal, or increased drive to obtain sex associated with this profile. Future research should replicate these results in a more diverse sample, and examine the efficacy of interventions redirecting participants away from a "low acting with awareness, low resignation" profile on sexual assault prevention.

Preventing Sexual Violence: A Behavioral Problem Without a Behaviorally Informed Solution

What solutions can we find in the research literature for preventing sexual violence, and what psychological theories have guided these efforts? We gather all primary prevention efforts to reduce sexual violence from 1985 to 2018 and provide a bird's-eye view of the literature. We first review predominant theoretical approaches to sexual-violence perpetration prevention by highlighting three interventions that exemplify the zeitgeist of primary prevention efforts at various points during this time period. We find a throughline in primary prevention interventions: They aim to change attitudes, beliefs, and knowledge (i.e., ideas) to reduce sexual-violence perpetration and victimization. Our meta-analysis of these studies tests the efficacy of this approach directly and finds that although many interventions are successful at changing ideas, behavior change does not follow. There is little to no relationship between changing attitudes, beliefs, and knowledge and reducing victimization or perpetration. We also observe trends over time, including a shift from targeting a reduction in perpetration to targeting an increase in bystander intervention. We conclude by highlighting promising new strategies for measuring victimization and perpetration and calling for interventions that are informed by theories of behavior change and that center sexually violent behavior as the key outcome of interest.

Links between Aggressive Sexual Fantasies and Sexual Coercion: A Replication and Extension of a Multifactorial Model

Current research indicates that aggressive sexual fantasies (ASF) are related to sexual aggression, above and beyond other risk factors for this behavior. There have, however, rarely been explicitly considered in multifactor models aiming to explain sexual aggression. One exception is the multifactorial Revised Confluence Model of Sexual Aggression that was replicated in two samples of male individuals who were convicted of sexual offenses and a small sample of men from the general population and evidenced a high relevance of ASF, respectively. There were, however, no further attempts to replicate the model in larger samples from the general population. We, therefore, used a subsample from the Finnish Genetics of Sexuality and Aggression project including 3269 men (age: M = 26.17 years, SD = 4.76) to do so. Cross-sectional latent structural equation models corroborated previous research and the assumption that ASF are a central component in multifactor models that aim to explain sexual aggression: ASF and antisocial behavior/aggression were equally important associates of sexual coercion when also considering adverse childhood experiences, hypersexuality, and callous-unemotional traits. Additionally, ASF mediated the links between hypersexuality, callous-unemotional traits, as well as childhood sexual abuse and sexual coercion. These links held stable when entering further risk factors, that is, distorted perceptions, rape-supportive attitudes, and violent pornography consumption into the model. Contrasting assumptions, alcohol consumption and antisocial behavior/aggression did not interact. These results illustrate the potential importance of ASF for sexual aggression. They indicate that ASF require consideration by research on sexual aggression as well as in the treatment and risk assessment of sexual perpetrators.

When Kinks Come to Life: An Exploration of Paraphilic Behaviors and Underlying Predictors

Paraphilia is defined as a condition in which sexual excitement relies on fantasizing about and/or participating in unusual sexual behavior. Although recent studies have assessed the concordance between paraphilic interests and paraphilic behaviors, few studies have studied which individual traits and demographics predict engaging in paraphilic behaviors, or the level of concordance between arousal and behavior. The current study replicated and expanded Joyal and Carpentier's 2022 study. We assessed concordance between paraphilic arousal and behavior. Further, we assessed the impact of Dark Tetrad traits, impulsivity, social desirability and demographic variables on engaging in paraphilic behaviors using self-report questionnaires in a sample from the general population and FetLife. Finally, we were interested in whether these individual differences moderated the concordance between arousal and behavior. Results indicated high concordance between paraphilic arousal and behavior for all paraphilias except pedophilia and hebephilia. Younger, male participants were more likely to engage in various paraphilias than women and older participants. Machiavellianism was linked with lower paraphilic behavior, particularly impulsive or risky ones. Psychopathy predicted engaging in more deviant or illegal paraphilias, whereas sadism only showed an association for engaging in frotteurism and narcissism was not a predictor for engaging in any paraphilia. For several paraphilias, individual traits moderated the effect of arousal on behavior. Implications of these findings and future directions are discussed.

Revisiting the Role of Pornography Use in the Confluence Model Theory of Sexual Aggression

This research tested Confluence Model reasoning that pornography use should be related to sexual aggression among men who are high but not low in the predisposing risk factors of hostile masculinity (HM) and impersonal sexuality (IS). This hypothesis was examined with three online surveys of young adult males, including an American Mechanical Turk sample (N1 = 1,528, Mage = 22.46 years); a national sample of Canadian students (N2 = 1,049, Mage = 20.89 years); and a national sample of Canadian non-students (N3 = 905, Mage = 21.66 years). As expected, synergistic interactions between HM and IS reliably predicted self-reported sexual aggression across samples. Results with respect to interactions with pornography use were more complex. The Confluence Model hypothesis was supported when pornography use was operationalized as the use of nine specific magazines but it was not supported when pornography use was operationalized with a contemporary inclusive approach that included use of internet materials. These discrepant findings are difficult to account for with Confluence Model theorizing and highlight the non-equivalence of pornography use measures in survey research.

Empirically-based dynamic risk and protective factors for sexual offending

This review provides an overview and update of empirical evidence for psychologically meaningful dynamic risk factors and protective factors for sexual offending. Using the review by Mann et al. (2010) as a starting point, we reviewed relevant literature that has appeared since this publication, focusing on meta-analyses, systematic and scoping reviews of dynamic risk factors, recent evaluations of commonly used dynamic assessment tools, and studies of dynamic risk and protective factors in community samples in addition to clinical or forensic samples. Two risk factors previously deemed promising by Mann et al. (2010), hostility towards women and dysfunctional coping (conceptualized as hostile masculinity and emotional regulation deficits, respectively, in this review), could now be considered supported using this review's criteria of three or more studies demonstrating an effect size of 0.15 or greater. No new risk factors were identified. We conducted a broader search of protective factors in recognition of the relative newness of this literature: Positive social support was the only protective factor identified as empirically supported. We also discuss situational risk and protective factors.

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.

Risk factors for perpetrating sexual aggression among adolescents: Differences by gender and sexual orientation

Although anyone-regardless of gender or sexual orientation-can perpetrate sexual aggression, most studies examining risk factors for engaging in sexual aggression include samples of boys and men, and do not consider the sexual orientation of the respondent. The current study addresses this gap in the literature by examining how risk factors for sexual aggression vary as a function of gender and sexual orientation in a sample of 1782 high school youth. Participants completed surveys evaluating engagement in consent behaviors, rape myth acceptance, perception of peer rape myth acceptance, perceived peer engagement in violence, and perceived peer support for violence. A one-way MANOVA found that constructs varied as a function of gender and sexual orientation. Specifically, heterosexual boys reported lower engagement in consent behaviors, higher rape myth acceptance, and higher perceived peer support for violence compared to heterosexual girls and sexual minority girls. The results highlight the importance of considering gender and sexual orientation when designing sexual aggression prevention programs.

Predictors of sexual aggression among gay men and lesbian women: An application of Malamuth's confluence model

The present study investigated whether the core constructs of Malamuth's confluence model (i.e., hostility against individuals of the same sex and sexual orientation [HASSO], impersonal sexuality [IS], and high dominance/low nurturance [HDLN]) could predict sexual aggressive behavior (SA) of gay men against other gay men and of lesbian women against other lesbian women. For both gay men (N = 226) and lesbian women (N = 190) regression analysis showed that IS, HDLN, and especially HASSO proved to be important predictors for sexual aggression. The confluence of all three risk factors in terms of a three-way interaction added to the prediction of SA in lesbian women but not in gay men. Overall, the three predictors explained 30% of the variance in SA among men and 62% of the variance in SA among women.

The Role of Pornography Use in Intimate Partner Violence in Different-Sex Couples: A Prospective Longitudinal Study

Pornography use and intimate partner violence (IPV) are both prevalent in romantic relationships. However, information is lacking about whether pornography use predicts IPV. This study examined the relation between frequency of pornography use (FPU) and IPV across a span of 4 months in a sample of 132 different-sex couple dyads. At least one partner in each couple was attending a Canadian university. Participants (N = 264) completed online measures of pornography use, IPV, and social desirability at baseline and at a 4-month follow-up. Two longitudinal actor-partner interdependence models using a structural equation framework to conduct path analyses demonstrated that (a) higher FPU among men at baseline predicted increases in IPV perpetration and victimization from baseline to 4-month follow-up for both men and women and (b) women's baseline FPU did not predict change in IPV over time for themselves or their partners. These findings suggest that frequent pornography use among male partners in different-sex romantic relationships may represent an under-recognized risk factor for IPV, and further research is needed to identify latent factors that may be contributing to this relation. Although women's baseline FPU did not predict changes in IPV over time, this may be because women used pornography less frequently than men.

Understanding Sexual Aggression in UK Male University Students: An Empirical Assessment of Prevalence and Psychological Risk Factors

University-based sexual aggression is an international public health issue; however, to date, there have been no formal assessments of the prevalence or psychological indicators associated with the proabuse behaviors of the most common perpetrators at UK universities: heterosexual male students. To facilitate the development of effective primary prevention interventions for domestic students who have sexually harmed, we assess across two empirical studies (Ns = 259 and 295) the psychological risk factors associated with recent sexual aggression amongst two distinct samples of UK male university students. Cumulatively, results highlighted that one in nine participants (11.4%) self-reported recent sexual aggression. These participants could be statistically differentiated from their non-offending peers on various established indicators of general sexual offending, of which logistic regression analyses highlighted atypical sexual fantasies, general aggression, hostility toward women, and rape myth acceptance as being the most reliable predictors. Our data extend the international evidence base by providing the first detailed overview of sexual aggression amongst UK male university students, as well as the psychological risk factors associated with their proabuse behaviors. We discuss the importance of our findings for the development of more effective evidence-based reduction strategies and primary prevention interventions for male students who have sexually harmed.

Sexual Aggression among Women and Men in an Iranian Sample: Prevalence and Correlates

This pre-registered study examined the prevalence and correlates of sexual aggression in a sample of 530 Iranians (322 women, 208 men) with a behaviorally specific questionnaire distinguishing between different coercive strategies, victim-perpetrator relationships, and sexual acts. Significantly more women (63.0%) than men (51.0%) experienced at least one incident of sexual aggression victimization since the age of 15 years, and significantly more men (37.0%) than women (13.4%) reported at least one incident of sexual aggression perpetration. In women and men, the experience of child sexual abuse predicted sexual victimization and sexual aggression perpetration after the age of 15 years, both directly and indirectly through higher engagement in risky sexual behavior. Greater endorsement of hostile masculinity among men explained additional variance in the prediction of sexual aggression perpetration. This research is a first step towards documenting and explaining high rates of sexual aggression victimization and perpetration among Iranian women and men, providing important information for sex education as well for the prevention of sexual aggression. However, to achieve these goals, we highlight the need for systematic actions in all educational, social, and legal sectors of Iranian society.

Social Cognitive Processes Underlying Normative Misperception of Sexual Judgments

Acquaintance-initiated sexually aggressive behavior (SAB) is a widespread problem on college campuses, and intervention strategies thus far have not produced sustained reductions in SAB. Peer-related social norms and cognitive processes underlying sexual decision-making have separately been implicated in SAB. The present study integrates this work by examining the effect of perspective (self vs. typical college male referent) on college men's judgments of the justifiability of unwanted sexual advances, determining the cognitive processes underlying men's misperceptions, and evaluating rape-supportive attitudes (RSA) as a correlate of the implicated processes. College men attracted to women (n = 217) completed the Heterosocial Perception Survey-Revised, in which they judged the justifiability of a man's increasingly intimate sexual advances as a woman responds increasingly negatively. Participants completed the Heterosocial Perception Survey-Revised from their own perspective and from the typical college male perspective. Participants also completed questionnaires assessing RSA and demographics. Undergraduate men, and particularly those endorsing more RSA, greatly overestimated how much the typical college male perceives increasingly nonconsensual behavior as justified. Three cognitive processes were strongly implicated in this misperception. When responding from the self-perspective, RSA correlated significantly with all cognitive processes. These findings illustrate the utility of integrating work on social norms and cognitive processing to document the global effect of perspective on average justifiability ratings and the perspective effect on cognitive processes underlying the ratings. Future work should evaluate personalized normative feedback and cognitive-training approaches to target misperceptions of peers' sexual judgments, given the well-established relation between sexual misperception and SAB risk.

The Scope of Rape Victimization and Perpetration Among National Samples of College Students Across 30 years

Research Questions: Rape prevention practice and policy have roots in data from 1985. This study uses 2015 national data to project recent prevalence, assesses whether rates now differ from those of 30 years ago, and disaggregates 2015 prevalence into rape of alcohol incapacitated victims, rapes combining both alcohol and physical tactics, and violent rape. Methods: Cross-sectional analyses were conducted comparing two national samples. The first was collected in 1984-85 (Koss, Gidycz, & Wisniewski, 1987); the second was collected 30 years later in 2014-2015. Both surveys used in-person administration and measurement by the most current version at the time of the Sexual Experiences Survey (SES). Prevalence rates were compared using Bayesian binomial tests. Results: In 2015, 33.4% (1 in 3) of women reported experiencing rape or attempted rape and 12.7% of men reported perpetration (1 in 8). Using Jeffreys' label for effect size of the Bayes binomial (1961), both results are "decisively" greater than expected given the 1985 benchmarks of 27.9% for victimization and 7.7% for perpetration. Victimization when incapacitated characterized approximately 75% of incidents in 2015 up from 50% in 1985. Cautions apply as cross-sectional data does not establish causality and the recent data set involved the revised SES. Conclusions: Across 30 years, neither containment nor reduction of rape was demonstrated and the increasingly prominent association with alcohol was apparent. Among the men who disclosed raping, 9 of 10 incidents were alcohol-involved. Prevention focus might profitably be directed to constraining alcohol environments and policies that facilitate rape of incapacitated persons and on misconduct responses that are proportional to the harm caused to rape victims, thereby raising the perceived risks of perpetration.

Pornography, impersonal sex, and sexual aggression: A test of the confluence model in a national probability sample of men in the U.S

This paper reports findings on men's exposure to extreme pornography, impersonal sexuality, and sexual aggression from the National Survey of Porn Use, Relationships, and Sexual Socialization, a U.S. population-based probability study. Despite Malamuth's confluence model (CM) of sexual aggression positing that an impersonal approach to sex interacts with exposure to pornography to predict the likelihood of committing sexual assault, only a few studies have actually tested this prediction. Additionally, the data from the only previous nationally representative study were gathered more than 30 years ago. Results of the present study generally supported the CM. Extreme pornography exposure and impersonal sexuality were both associated with a higher probability of sexual aggression. Although impersonal sex was a robust predictor in and of itself, men who were more exposed to pornography and impersonal in their approach to sex were more likely to be sexually aggressive than men who were impersonal in their approach to sex but less exposed to pornography. Results maintained when indicators of sex drive were included in analyses. The only finding inconsistent with the CM was that the association between pornography exposure and sexual aggression was stronger among men lower rather than higher in impersonal sex.
