The role of dominant personality traits in multiple perpetrator rape proclivity

Abstract

Background/Aim Multiple perpetrator sexual assaults (MPSA) often involve more severe forms of sexual violation and result in a host of impairments for the victim. To further investigate the characteristics of MPSA, researchers have taken an interest in personality traits, varying group dynamics, and the role a leader may play. This study examines the possible linkage between dominant personality characteristics and the propensity to engage in multiple perpetrator sexual assault. Method Using anonymous online surveys, university student participants were assessed on The Personality Scale for Dominance and the Multiple Perpetrator Rape Proclivity Scale (M-PRIS). We hypothesized that dominant personality traits would predict M-PRIS proclivity score. Results Of 176 respondents, 84 heterosexual males completed both measures. Dominance scores did not significantly predict total M-PRIS score, F(1,82) = 1.1, p = .296, the Enjoyment subscale score, F(1,82) = .66, p = .420, the Likelihood subscale score, F(1,86) = 1.13, p = .292, or the Arousal subscale score, F(1,82) = 0.66, p = .419. Conclusion In this study, dominance was not associated with a proclivity for multiple perpetrator sexual violence. Other important factors, such as psychopathy or deviant sexual interests, may mediate the relationship between dominant personality traits and the tendency to initiate a multiple perpetrator sexual assault. Future studies should examine alternative relationships in hopes of gaining a clearer picture of individuals who exhibit a proclivity for sexual violence with the aim to inform prevention and practice.
