Sexual aggression within the UK and western societies is wide-spread and has extremely negative consequences for its victims. The aim of the current research was to explore rejection sensitivity as an independent risk factor for sexual aggression. Additionally, adversarial sexual beliefs (ASB) is a particularly salient risk factor that has been included in some of the most prominent models of sexual aggression. Therefore, this study also furthered research in the area by investigating a possible moderating effect of ASB on the relationship between rejection sensitivity and sexual aggression. The association between ASB and sexual aggression was also looked at independently. Forty-nine male participants aged between 18 and 30 were gathered using opportunity sampling. Participants were required to answer three questionnaires; sexual experiences survey, adversarial sexual beliefs scale and the interpersonal sensitivity measure. Results showed no significant correlation between ASB and sexual aggression or rejection sensitivity and sexual aggression and no moderating effect of ASB. Very low levels of ASB and sexual aggression were found in the sample and there was very little variation between participants’ scores on both ASB and sexual aggression as well. This study’s findings do not support ASB as an established risk factor, nor do they support rejection sensitivity as a new risk factor for sexual aggression. It is concluded that a possible explanation for not finding a correlation between ASB and sexual aggression is because ASB is an outdated belief systems that is no longer prevalent within young samples, this would also account for the lack of moderating effect of ASB on rejection sensitivity as a risk factor. Future research should re-examine whether ASB is still a commonly held belief in young populations to answer the questions raised by this study about its salience with a modern-day sample.
