T1  - Correlates of victim-perpetrator overlap in sexual aggression among men and women
BT  - a conceptual replication and extension
JF  - Psychology of violence
N2  - Objective: The study replicated and extended a study by Peterson, Beagley, McCallum, and Artime (2019), who studied differences in sexual attitudes and behaviors in men who were both victims and perpetrators of sexual assault, only victims, only perpetrators, or neither. They found a heightened rate of childhood sexual abuse (CSA) and some evidence of greater traumatic sexualization in men who were both victims and perpetrators. 
Method: Our sample consisted of 2,149 college students (39.6% male) in Germany. We measured sexual aggression perpetration and victimization, CSA, sexual self-esteem, depressive symptoms, risky sexual scripts, and risky sexual behavior. 
Results: Perpetration rates were significantly higher among victims than among nonvictims, and the victim-perpetrator group scored highest on CSA. A significant effect of group membership was found on measures of depressive symptoms, risky sexual scripts, and risky sexual behavior in both sex groups, mainly due to differences of the victim-only, perpetrator-only, and victim-perpetrator groups from the nonvictim-nonperpetrator group. The effect on sexual self-esteem was found for women only. Few differences emerged between the victim-only, perpetrator-only, and victim-perpetrator groups. Most associations remained significant when controlling for CSA.
Conclusion: We found a substantial overlap between victimization and perpetration but no evidence for a special vulnerability of the victim-perpetrator group. Instead, experiences of victimization, perpetration, or both were linked to more negative correlates compared with individuals who were neither victims nor perpetrators. The findings need to be interpreted with caution due to the small number of individuals in the perpetrator-only and victim-perpetrator groups.

T1  - Changing cognitive risk factors for sexual aggression
BT  - Risky sexual scripts, low sexual self-esteem, perception of pornography, and acceptance of sexual coercion
JF  - Journal of interpersonal violence
N2  - Sexual aggression is a problem among college students worldwide, and a growing body of research has identified variables associated with an increased risk of victimization and perpetration. Among these, sexuality-related cognitions, such as sexual scripts, sexual self-esteem, perceived realism of pornography, and acceptance of sexual coercion, play a major role. The current experimental study aimed to show that these cognitive risk factors of sexual aggression victimization and perpetration are amenable to change, which is a critical condition for evidence-based intervention efforts. College students in Germany (N = 324) were randomly assigned to one of three groups: a treatment group designed to change participants' sexual scripts for consensual sex with regard to the role of alcohol consumption, casual sex, and ambiguous communication of sexual intentions as risk factors for sexual aggression (EG1), a treatment group designed to promote sexual self-esteem, challenge the perceived realism of pornography, and reduce the acceptance of sexual coercion (EG2), and a non-treatment control group (CG). Baseline (T1), post-experimental (T2), and follow-up (T3) measures were taken across an eight-week period. Sexual scripts contained fewer risk factors for sexual aggression in EG1 than in EG2 and CG at T3. Sexual self-esteem was enhanced in EG2 at T2 relative to the other two groups. Acceptance of sexual coercion was lower in EG2 than in EG1 and CG at T2 and T3. No effect was found for perceived realism of pornography. The findings are discussed in terms of targeting cognitive risk factors as a basis for intervention programs.
