Unacknowledged and missed cases of sexual victimization: A comparison of responses to broad versus behaviorally specific questions

Evaluating a Theory-Based Online Program for Preventing Sexual Aggression: An Experimental-Longitudinal Study With German University Students

This pre-registered study evaluated an intervention designed to reduce sexual aggression perpetration and victimization by changing risky scripts for consensual sexual interactions and corresponding risky sexual behavior, and by improving sexual self-esteem, refusal assertiveness, and initiation assertiveness. In a four-wave longitudinal study covering 23 months, 1181 university students in Germany (762 female) were randomly assigned to an intervention and a no-intervention control group. The intervention group completed six weekly modules addressing the targeted theory-based risk and vulnerability factors of sexual aggression perpetration and victimization. Controlling for baseline levels (T1), the intervention group showed less risky sexual scripts one week post-intervention (T2), which predicted less risky sexual behavior nine months later (T3), which predicted lower odds of sexual aggression perpetration and victimization 12 months later (T4). No direct intervention effects on rates of sexual aggression perpetration and victimization at T3 and T4 were found. No indirect intervention effect on sexual aggression was found via sexual self-esteem and sexual assertiveness. However, sexual self-esteem at T2, which was higher in the intervention group, predicted lower odds of sexual aggression victimization at T3 via higher initiation assertiveness at T3. Implications for reducing sexual aggression and conceptualizing risk and vulnerability factors of sexual aggression are discussed.

Pathways from childhood sexual abuse to sexual aggression victimization and perpetration in adolescence and young adulthood: a three-wave longitudinal study

BACKGROUND

Childhood sexual abuse (CSA) has been identified as a risk factor for later sexual aggression perpetration and vulnerability factor for sexual victimization. However, the use of cross-sectional designs, the focus on female victimization and male perpetration, and the lack of evidence from outside North America limit the existing knowledge base.

OBJECTIVE

The study was designed to examine pathways from CSA to sexual revictimization and sexual aggression perpetration after the age of consent.

METHOD

A total of 588 university students in Germany (308 female) took part in a three-wave longitudinal study covering 23 months. At each wave (T1-T3), all participants completed measures of sexual aggression victimization and perpetration. Experiences of CSA were measured at T1.

RESULTS

The rate of CSA was significantly higher for women (20.8%) than for men (12.4%). Rates of sexual victimization for women were 60.9% at Time 1 (since age 14), 22.3% at Time 2 (since T1), and 17.4% at Time 3 (since T2). For men, the rates were 39.2% at Time 1, 15.9% at Time 2, and 14.1% at Time 3. Rates of sexual aggression perpetration for women were 10.6% at Time 1 (since age 14), 3.5% at Time 2 (since T1), and 3.6% at Time 3 (since T2). For men, the rates were 18.0% at Time 1, 6.2% at Time 2, and 3.8% at Time 3. The gender differences in victimization and perpetration were significant only at T1. CSA predicted higher odds of sexual aggression victimization and perpetration cross-sectionally at T1 and indirectly at T2 and T3 via T1. Gender did not moderate the associations.

CONCLUSION

The results confirm previous findings of elevated rates of sexual aggression victimization and perpetration in adolescence and young adulthood in victims of CSA. The implications for understanding and preventing adverse sexuality-related outcomes of CSA are discussed.

Measuring sexual violence perpetration acknowledgment: Testing the effects of label and response format

Individual acknowledgment of sexual assault and rape perpetration is extraordinarily low in prior research. Only about 1% of individuals report perpetrating rape, in contrast to the 6% perpetrating rape as estimated by using behaviorally specific items that exclude stigmatized words such as rape. The goal of this study was to examine two possible measurement mechanisms for increasing perpetration acknowledgment: label choice and response format. In Sample 1 (N = 291), participants completed two acknowledgment items which varied in label choice. One item used the term rape; one used the term sexual assault. Acknowledgment of perpetration using the label sexual assault was significantly higher than when using the term rape (6.38%-1.71%, p = .01, Cohen's d = 0.44). In Sample 2 (N = 438), participants were presented with a scaled and a dichotomous sexual assault item at different parts of the overall survey. Sexual assault acknowledgment was higher on the scaled item compared to the dichotomous item (15.75% vs. 3.2%, p < .0001, Cohen's d = 0.64). Rates of sexual perpetration as measured behaviorally were higher for ambiguous acknowledgment types ("might or might not," "probably not") than for those reporting "definitely not," (76.81% vs. 29.0%, p < .0001, Cohen's d = 0.59). The two different measurement strategies tested here, using a less stigmatized label such as sexual assault and using a scaled response format, both increased rates of perpetration acknowledgment 3-15x greater than rates documented in prior research.

Scripts for consensual sex as risk factors for sexual aggression: A three-wave longitudinal study with university students in Germany

BACKGROUND

Sexual aggression is a major problem among young adults. Sexual scripts are cognitive schemata representing typical elements of sexual interactions and serve as guidelines for sexual behavior. They may be linked to the risk of sexual aggression if they contain elements known to be associated with the perpetration of sexual aggression, such as alcohol use, sex with casual partners, and ambiguous communication of sexual intentions.

OBJECTIVES

The study was designed to examine pathways from risky sexual scripts for consensual sex to risky sexual behavior and sexual aggression perpetration in men and women.

DESIGN

The study employed a three-wave longitudinal design with 12-month intervals. Participants were 2425 university students in Germany (58% female).

METHODS

At each wave (Time 1-Time 3), participants completed measures of risky sexual scripts and risky sexual behavior, defined by three aspects: Casual sex, alcohol consumption, and ambiguous communication of sexual intentions. Reports of sexual aggression perpetration were collected since the age of consent (14 years; Time 1) or in the past 12 months (Time 2 and Time 3) using the Sexual Aggression and Victimization Scale.

RESULTS

Perpetration rates for men were 9.8% at Time 1, 12.2% at Time 2, and 9.5% at Time 3. For female participants, the corresponding rates were 6.0% at Time 1, 6.3% at Time 2, and 5.1% at Time 3. The gender difference was significant at Time 1 and Time 2, but not at Time 3. As hypothesized, more risky sexual scripts prospectively predicted more risky sexual behavior, which predicted a higher risk of sexual aggression perpetration. The findings held for men and women and for participants with exclusively opposite-sex and with both opposite- and same-sex contacts.

CONCLUSION

Scripts for consensual sex may be risk factors for sexual aggression among men and women if they contain elements identified as risk factors for sexual aggression. The findings suggest that changing risky sexual scripts for consensual sex may be a promising strategy for preventing sexual aggression perpetration.
