Trajectories of Posttraumatic Stress and Depression in Police and Community Members Following the Violence during Civil Unrest in Ferguson, Missouri.

Longitudinal research following discreet traumatic events reveals distinct symptom trajectories in untreated survivors of trauma. Trajectories within communities exposed to shared, prolonged violence involving subgroups differing in perspectives, and roles during the event have not been studied. This study examined trajectories of posttraumatic stress (PTS) and depressive symptoms secondary to exposure to violence during civil unrest in citizens (n = 311) and law enforcement (n = 255) over 1.5 years following exposure. Latent class growth modeling was used to examine trajectories of PTS and depressive symptoms. Four-class quadratic solutions for both PTS and depressive symptoms demonstrated best fit. Similar patterns emerged for such that most participants were classified as resistant (57% and 67%, respectively), followed by resilience (23.8% and 17.2%), chronic (12.6% and 12.0%), and worsening (6.1% and 4.4%). When all predictors were entered in a single model, race, and membership in citizen or law enforcement groups did not distinguish trajectories of recovery. Higher income and social support emerged as consistent protective factors against PTS and depressive symptoms, while trauma history emerged as a risk factor for PTS. Women were more at risk for depressive symptoms only. Implications for improving police/civilian relations in Ferguson, Missouri, and other communities are discussed.

Exposure to Violence During Ferguson Protests: Mental Health Effects for Law Enforcement and Community Members.

There is little information available on the mental health effects of exposure to shared community violence such as the August 2014 violence that occurred in Ferguson, Missouri. This study sought to examine the relationship between proximity to community violence and mental health in both community members and police officers. We recruited 565 adults (community, n = 304, and police, n = 261) exposed to the violence in Ferguson to complete measures of proximity to violence, posttraumatic stress, depression, and anger. Using structural equation modeling, we assessed aspects of proximity to violence-connectedness, direct exposure, fear from exposure, media exposure, reactions to media, and life interruption-as correlates of posttraumatic stress disorder (PTSD) symptoms, depression, and anger. The final model yielded (n = 432), χ(2) (d = 12) = 7.4, p = .830; comparative fit index = 1.0, root mean square error of approximation = 0 [0, .04]. All aspects of proximity except direct exposure were associated with mental health outcomes. There was no moderation as a function of community versus police. Race moderated the relationship between life interruptions and negative outcomes; interruption was related to distress for White, but not Black community members. Based on group comparisons, community members reported more symptoms of PTSD and depression than law enforcement (ηp (2) = .06 and .02, respectively). Black community members reported more PTSD and depression than White community members (ηp (2) = .05 and .02, respectively). Overall, distress was high, and mental health interventions are likely indicated for some individuals exposed to the Ferguson events.

Effects of Experimenter Contact, Setting, Inquiry Mode, and Race on Women's Self-Report of Sexual Attitudes and Behaviors: An Experimental Study.

Factors related to the research context, such as inquiry mode, setting, and experimenter contact, may affect participants' comfort with and willingness to disclose certain sexual attitudes or admit to engaging in sensitive sexual behaviors. In this study, 255 female undergraduates (42.7 % non-White) completed a survey containing measures of sexual behavior and attitudes. The level of experimenter contact (high vs. low contact), setting (in lab vs. out of lab), and inquiry mode (pencil-and-paper vs. computer) were manipulated and participants were randomly assigned to conditions. We hypothesized that low-contact, out-of-lab, computer conditions would be associated with more liberal sexual attitudes and higher rates of reported sexual behaviors than high-contact, in-lab, and paper-and-pencil conditions, respectively. Further, we hypothesized that effects would be moderated by race, such that differences would be greater for non-White participants because of concerns that reporting socially undesirable behavior might fuel racial stereotypes. For attitudinal measures, White participants endorsed more liberal attitudes toward sex in high-contact conditions and non-White participants endorsed more liberal attitudes in low-contact conditions. For behavioral measures, non-White participants reported more behaviors on pencil-and-paper surveys than on computers. White participants demonstrated no significant mode-related differences or reported more sexual behaviors in computer conditions than paper-and-pencil conditions. Overall, results suggest that experimenter contact and mode significantly impact sexual self-report and this impact is often moderated by race.

Consenting to sexual activity: the development and psychometric assessment of dual measures of consent.

Sexual assault prevention efforts have focused on educating students to obtain consent as a mechanism to reduce sexual assault, yet little is known about how college students consent to sex. Additionally, there are currently no measures available to assess students' consent to sex. The current study aimed to better understand college students consent by using a systematic approach to develop validated measures of sexual consent. This study integrated mixed methods via three phases and two waves of data collection to develop two measures of consent. In Phase 1, qualitative data were collected from college students (n = 185) to inform the design of quantitative measures aimed at assessing sexual consent at last sexual intercourse. In Phase 2, items were written for the closed-ended quantitative instrument and reviewed by a team of experts, educators, and clinicians. In Phase 3, a quantitative survey was administered to college students (n = 660) which included the measures of consent developed from the Phase 1 data; the measures were assessed for their psychometric properties. Exploratory factor analyses were utilized to assess the measures and resulted in five factors each for both consent scales. Both scales had high internal consistency reliability, showed gender differences, and showed differences across relationship status (single vs. in a relationship). The two newly developed measures assess unique constructs of consent and demonstrate assessments of specific concepts. Our findings provide an important contribution to the field of sexuality as these measures can be used in future research to better understand sexual consent.

Physiological reactivity in a community sample of sexually aggressive young men: a test of competing hypotheses.

Men's sexually aggressive behavior potentially could relate to either physiological hyporeactivity or hyperreactivity, and these two different physiological profiles could be associated with different underlying causes of sexual aggression. Thus, measurement of physiological reactivity could provide insight into mechanisms relevant to the etiology of sexual aggression. The relationship between sexual aggression and physiological reactivity was investigated in 78 community men (38 sexually aggressive and 40 non-aggressive men). In a laboratory protocol, the men were exposed to neutral, negative-affect-inducing, and positive-affect-inducing stimuli. Men's salivary cortisol concentrations and electrodermal activity (EDA) were measured throughout the laboratory procedure. Sexually aggressive men demonstrated (1) lower overall cortisol levels and (2) lower EDA reactivity in some conditions as compared to non-aggressive men. Results of this study were consistent with the idea that men's sexual aggression is associated with physiological hyporeactivity, a physiological profile that has been found to be associated with externalizing behaviors and psychopathic traits.

Women's Experiences of Sexual Harassment in Online Gaming.

To better understand the types of sexual harassment women experience in online gaming, their labeling of such experiences, and the relationship between the perpetrator and the victim, we surveyed women gamers to inquire about their experiences. Participants were 182 women from North America who played online video games. Overall, 56.6% of participants reported experiencing one or more types of sexual harassment during online gaming. Additionally, 45.6% of participants reported witnessing one or more types of sexual harassment perpetrated against other women. About half (50.5%) of participants who had experienced harassment labeled their own experiences as "sexual harassment," and 42.2% labeled the behaviors that they witnessed against someone else as "sexual harassment." Results speak to the need for prevention interventions to protect women gamers.

Preliminary Prevalence Estimates of Sexual Exploitation as Measured by the Sexual Experiences Survey-Victimization (SES-V) in a National US Sample.

The new Sexual Experiences Survey-Victimization (SES-V) was designed to capture a larger range of sexual exploitation and to be applicable to more diverse populations than prior measures. This study represents the first administration of the SES-V in a national sample of adults (N = 347). Participants were recruited from a crowdsourcing platform and selected to reflect the national distribution in terms of age, sex, and race/ethnicity. Rates of sexual exploitation since age 14 were very high in this sample (90%), providing evidence that the SES-V was successful in capturing experiences on the low end of the severity continuum. Using the items corresponding to the FBI definition of rape, 60% of women and 29% of men endorsed rape on the SES-V. Compared to men, women reported higher rates of sexual exploitation overall, and higher rates of every type of sexual exploitation except technology-facilitated. The new SES-V also asks participants to estimate the number of separate instances of four types of sexual exploitation that they have experienced; results provided support for the value of these incident estimates in understanding the scope of sexual exploitation. Finally, this study evaluated new sexual acts and exploitative tactics that were added to the SES-V and found that they demonstrated utility and validity. These findings offer preliminary support for the validity and functionality of the SES-V, although the high prevalence of sexual exploitation on the SES-V is discussed as both a strength and limitation. Future research should evaluate prevalence and demographic differences in a larger national sample.

Quantifying Criminal Sexual Acts: The Illegal Sexual Exploitation Module of the Revised Sexual Experiences Survey-Victimization (SES-V) Measure.

Since the initial development of the Sexual Experiences Survey (SES) four decades ago, the SES has been designed to measure a range of forms of sexual exploitation, including acts that are coercive but not legally sanctioned as well as acts that legally qualify as crimes. That feature was retained in the revised Sexual Experiences Survey-Victimization (SES-V) measure. This article reviews the theoretical and empirical literature that guided the development of the Illegal Sexual Exploitation module of the SES-V, which measures experiences of nonconsensual exploitation resulting in sexual contact and which is designed to correspond to legal definitions across multiple jurisdictions. This article addresses research and applied contexts in which the distinction between legal and illegal sexual exploitation is important and the challenges and limitations involved in writing survey items that correspond to legal definitions. It also discusses revisions made to the items that make up the Illegal Sexual Exploitation module of the SES-V as compared to the illegal items in prior versions of the SES, including a new operationalization of non-consent and an expansion of the sexual acts and exploitative tactics that are included. Finally, the article discusses directions for future research on the Illegal Sexual Exploitation module of the SES-V.

Different Components of Sexual Narcissism Are Differentially Associated With Specific Sexual Aggression Strategies: An Exploratory Study Among Male and Female College Students.

Objectives: This study investigated whether components of sexual narcissism are associated with different types of sexual aggression (e.g., verbal pressure or force) among students because this is a prevalent problem on college campuses. Methods: College students (N = 508) were recruited for a cross-sectional online study. Results: Results showed that components of sexual narcissism were related to different strategies of sexual aggression, with sexual entitlement being associated with not providing the victim an opportunity to object and exploiting intoxication. Gender moderated some of the associations, with women showing a stronger relationship than men. Conclusions: These findings suggest that sexual narcissism represents a risk factor for sexual aggression in men and women and highlight the need for gender-inclusive and tailored interventions to prevent sexual aggression.

Preliminary Evidence of Validity for the Verbally Pressured and Illegal Sexual Exploitation Modules of the Sexual Experiences Survey-Victimization.

The Sexual Experiences Survey-Victimization (SES-V; see Koss et al., 2024) revises the prior 2007 Sexual Experiences Survey-Short Form Victimization (SES-SFV) in many ways, including expanded measurement of verbally pressured and illegal sexual exploitation, as well as the addition of items that assess being made to perform a sexual act or to penetrate another person sexually. The current article describes two initial validity studies of the SES-V. Study 1 compared rates of self-reported verbal pressure and illegal sexual exploitation (e.g. rape) on a preliminary version of the SES-V and the SES-SFV in a sample of higher education students who completed both questionnaires online in a randomized order (N = 460). As expected, the preliminary SES-V produced higher rates than the SES-SFV, and continuous scores were strongly correlated. Responses to the made-to-penetrate (MTP) items suggested that some cisgender men and women may have misunderstood those items. Study 2 explored responses to the MTP items further by randomly assigning participants to complete items with either the Study 1 MTP language (n = 269) or revised language (n = 245). The revised language produced fewer implausible responses and was adopted in the final version of the SES-V. These findings provide initial support for the validity of the SES-V and the value of expanding the conceptualization of victimization to include a wider range of sexual exploitation. A research agenda for future validity research is suggested.

Words Can Hurt: A Taxonomy of Verbally Pressured Sexual Exploitation in the SES-V.

This article describes the development of the Verbally Pressured Sexual Exploitation module of the Sexual Experiences Survey (SES)-Victimization (introduced by Koss et al., 2024). This module assesses the use of verbal or nonphysical, paraverbal pressure to obtain sexual acts without freely given permission. An interdisciplinary team of seven sexual exploitation researchers collaborated to create this module, with consultation from the full 15 member SES-V revision collaboration team. In this paper, we describe our process for developing this module. We briefly review empirical literature and theoretical frameworks (e.g., rape scripts, normative sexual scripts, intersectionality, and sex-positivity) that informed this work. Summary tables compare the SES-V items to verbal pressure items in prior versions of the SES and to other existing measures of violence. The comprehensive taxonomy developed herein includes six domains of Verbally Pressured sexual exploitation across 11 item stems. The components of the taxonomy include: positive verbal pressure, neutral verbal pressure, negative verbal pressure, substance-related pressure, postural violence, and threats to critical resources. The paper concludes with suggestions for future research, with priority on intersectional research that can illuminate the phenomenology and contexts of sexual exploitation against marginalized groups.

The Revised Sexual Experiences Survey Victimization Version (SES-V): Conceptualization, Modifications, Items and Scoring.

The Sexual Experiences Survey [SES] is considered the gold standard measure of non-consensual sexual experiences. This article introduces a new victimization version [SES-V] developed by a multidisciplinary collaboration, the first revision since 2007. The 2024 SES-V is designed to measure the construct of sexual exploitation since the 14th birthday. Notable revisions are adoption of a freely given permission standard for non-consent, introduction of new tactics and acts, including made to perform or to penetrate another person's body, tactics-first wording order, and emphasis on gender and sexual orientation inclusivity. The SES-V is modularized to allow whole or partial administration. Modules include Non-contact, Technology-facilitated, Illegal (largely penetrative), and Verbally pressured sexual exploitation. Tables provide item text, multiple scoring approaches, module follow-up, specific incident description and demographics. Future plans include developing a scoring algorithm based on weighting our hypothesized dimensions of sexual exploitation severity: invasiveness, pressure, and norm violation combined with frequency. This article is the first in a special issue on the SES-V. Subsequent articles focus on the taxonomies and literature that informed each module. The issue concludes with two empirical papers demonstrating the feasibility and validity of the SES-V: (1) psychometric comparison with the 2007 SES-SFV; and (2) prevalence data from a census-matched adult community sample.

Examining the Psychometric Properties of the Sexual Initiation Strategies Scale (SISS): A New Self-Report Measure of Sexual Aggression Perpetration History.

Psychometrically-sound measures of sexual aggression are essential for identifying risk factors for perpetration and examining the behavioral impact of prevention interventions. This project reports on the psychometric evaluation of a new measure of sexual perpetration-the Sexual Initiation Strategies Scale (SISS)-which was designed to correct for weaknesses in prior measures. In Study 1, scores on the SISS demonstrated reasonable convergent and divergent validity and test-rest reliability among a sample of mixed gender college students (N = 575). Participants were more likely to endorse having engaged in sexually aggressive behavior on the SISS than on two other measures of sexual aggression. In Study 2, rates of endorsement on the SISS also were higher than on the most commonly-used measure of perpetration in a community sample of men and women (N = 551) in which gay, lesbian, and bisexual participants were oversampled. In general, the SISS seemed to perform well as a measure of sexual aggression perpetration in both men and women and in those reporting both same- and other-gender sexual aggression. Advantages and disadvantages of the SISS as compared to other measures are discussed.

"I Can Tell You Wanna F***": A Content Analysis of Sexual Communication in Popular Song Lyrics.

Given that exposure to sexual messages in song lyrics can influence sociocultural norms and expectations surrounding consent communication between partners, we sought to understand the types of messages regarding sexual initiation and consent language that are available to media consumers. Through the lens of sexual script theory, we conducted a quantitative content analysis of sexual consent in pop (n = 197), hip-hop (n = 193), and country songs (n = 194) from 2016 to 2019. Differences in these messages were examined across singer gender, music genre, and time (pre- vs. post-#MeToo). Results indicated that references to sexual demands (e.g., "Strip that down") and sexual preferences (e.g., "I want it slow") were the most common types of sexual communication, appearing in approximately one-third of the singing parts included in the sample. Sexual suggestions (e.g., "Let's get nasty") and sexual requests (e.g., "Can I hit it?"), on the other hand, were the least common. References to inferred consent (e.g., "I can tell you wanna f***") appeared in approximately one-fifth of the singing parts. Both sexual demands and sexual preferences were more likely to appear in pop compared to hip-hop and country songs; however, these sexual communication messages did not significantly differ by male and female singers. Sexual requests were significantly more likely to appear in pre-#MeToo song lyrics. The messages embedded in popular songs may help to reinforce problematic scripts around sexual consent.

An Exploratory Study of Sexual Aggression Tactics as a Function of Perpetrator Gender and Victim Gender.

Objectives: This study sought to examine the association between perpetrator gender and victim gender and the use of sexually aggressive tactics (e.g., persistent enticement, verbal pressure, taking advantage of the inability to consent, and ignoring explicit non-consent). Methods: Participants were recruited from research panels to complete an online survey. They were asked to indicate which, if any, of 39 sexually aggressive tactics-representing four categories and nine subcategories-they had used to obtain sex, answering based on the gender with whom they most often have sex. Participants included 132 men who answered based on experiences with men (MSM), 131 men who answered based on experiences with women (MSW), 232 women who answered based on experiences with men (WSM), and 56 women who answered based on experiences with women (WSW). Results: MSM were more likely than all other groups to use enticement and more likely than WSM to engage in explicitly nonconsensual sex. WSM were more likely than MSW and WSW to take advantage of their partner's impaired ability to consent. There was no difference among groups in use of verbal pressure. Conclusions: Gendered sexual stereotypes may contribute to the types of tactics used by men and women against men and women.

Psychological Symptoms Associated with Sexual Victimization Experiences: Differences as a Function of the Type and Number of Sexual Acts and Aggressive Tactics.

Different types of sexual victimization are associated with different outcomes; for example, on average, physically forced sex is associated with worse psychological outcomes than verbally coerced sex. This study evaluated outcomes associated with sexual victimization as a function of sexual act and aggressive tactic, expanding upon the acts and tactics examined in prior studies. Participants who had experienced sexual victimization (N = 402) completed a survey about their most upsetting victimization experience, identifying the sexual act(s) and aggressive tactic(s) that occurred. They completed measures of PTSD, depression, anger, and trauma-related cognitions. Relationships between symptom severity and most upsetting act and tactic, as well as the number of acts and tactics, were analyzed. Related to the sexual act, non-penetrative sexual acts were associated with the lowest symptom severity on several measures. Related to the aggressive tactic, sex obtained through anger/criticism and physical force were associated with the greatest symptom severity on some measures. A larger number of tactics were associated with more severe symptoms on all measures, whereas number of acts only explained unique variance in PTSD symptom severity. The pattern of severity for outcomes differed from previous conceptualizations, suggesting that current hierarchies of victimization severity may require revision.

The Impact of Sexual Arousal and Emotion Regulation on Men's Sexual Aggression Proclivity.

Extant literature supports a relationship between sexual arousal and increased likelihood of sexually coercive behavior in men. The present study investigated the impact of sexual arousal on sexual coercion proclivity and the degree to which emotion regulation moderated this relationship in the context of two separate affect inductions. We predicted that sexual arousal would more strongly predict sexual coercion likelihood for men scoring lower on emotion regulation ability compared with men with above average emotion regulation abilities. Male participants with (n = 38) and without (n = 40) self-reported histories of sexual coercion were recruited from urban sexually transmitted infection testing clinics. Participants completed a measure of emotion regulation, underwent a positive and negative affect induction, viewed an erotic video, and reported on their level of sexual arousal immediately prior to completing a hypothetical sexual coercion likelihood laboratory task. Relationships between emotion regulation, sexual arousal, and sexual coercion likelihood were examined using moderation analyses. Sexual arousal was associated with greater reported sexual coercion likelihood. For men with poorer emotion regulation, sexual arousal significantly and positively predicted sexual coercion likelihood in the positive affect condition. Sexual arousal did not significantly predict sexual coercion for men with above average emotion regulation. Findings may have implications for the assessment of individual risk for coercive sexual behavior as well as primary prevention efforts.

Self-Persuasion: An Experimental Evaluation of a Sexual Aggression Preventive Intervention for U.S. College Men.

Grounded in the self-persuasion paradigm (an indirect persuasion approach, which places people in situations that motivate them to change their behavior), this study evaluated a brief, online intervention to reduce sexual aggression perpetration and increase prosocial bystander behaviors among heterosexual male college students (N = 241) in the United States. Students were randomly assigned to three conditions: (a) a self-persuasion intervention, (b) a social norms control condition, and (c) a control condition focusing on sense of belongingness. The self-persuasion intervention integrated three social psychological theoretical perspectives on attitudinal and behavioral change-cognitive dissonance (e.g., creating a personalized video message for incoming male college freshmen to explain the importance of consent in sexual contact), self-affirmation (e.g., reflecting on one's core values and how they are congruent with sexual consent), and personal relevance (e.g., writing about personally relevant reasons to always seek consent when having sexual contact). Participants in the self-persuasion condition reported greater prosocial bystander behaviors (e.g., intervening in situations to prevent sexual aggression) 6 months after the intervention as compared with those in the other two conditions; however, there were no significant difference in the rate of self-reported sexual aggression perpetration across conditions. The positive effect of the self-persuasion intervention on prosocial bystander behaviors was mediated by reduced self-perceived likelihood to commit sexual aggression and moderated by in-group solidarity with other college students. That is, the intervention had the most positive effect on prosocial bystander behaviors among participants with a lower sense of in-group solidarity. These findings are discussed in light of the promise of self-persuasion for future sexual aggression prevention work.

Female sexual self-schema after interpersonal trauma: relationship to psychiatric and cognitive functioning in a clinical treatment-seeking sample.

This study assessed the relationship between sexual self-schema and posttraumatic functioning in a clinical sample of 112 female sexual assault survivors. Contrary to hypotheses, posttraumatic stress disorder and depressive symptom severity were unrelated to the valence of sexual self-schema. Yet, negative posttraumatic cognitions were related to sexual self-schemas. Specifically, less positive self-views were associated with more negative schema (r = -.35). In a multivariate analysis, the measure of negative views of the world and others was associated with more positive schema. Results indicate that intervening to improve survivors' postassault appraisals of the self may help to reduce the impact of interpersonal trauma on women's sexual functioning.

Negative Cognitions Following Distressing Unwanted Sex: The Role of Coercion Severity and Perceived Consent.

Findings from past research suggest that unwanted sex (i.e., sex that is not fully desired) can result in a variety of outcomes, ranging from positive to negative. Some research has demonstrated that more severe coercion within unwanted sex is associated with more negative cognitions (particularly self-blame) following the unwanted sex, but findings are inconsistent. Previous research also has demonstrated that individuals' perceptions of how much they consented to sex-regardless of the level of coercion-are associated with negative cognitions. In this study, we aimed to explore the potential moderating role of perceived consent in the relationship between sexual coercion severity and negative cognitions following unwanted sex. Participants (N = 196) who had had a distressing unwanted sexual experience provided descriptions of their most distressing experience, rated their perceptions of how much they consented to this experience, and completed a questionnaire measuring the amount and content of negative cognitions they experienced following this experience. Two independent raters coded descriptions to determine coercion severity. Results demonstrated that perceived consent significantly moderated the relationship between coercion severity and two types of negative cognitions: characterological self-blame and negative thoughts about the world. This suggests that individuals' perceptions of their consent are often as important as the level of coercion involved in predicting cognitive outcomes of unwanted sex.
