This study sought to identify cognitively structured belief systems of men that are associated with sexual aggression. The structures of narcissism and Machiavellianism were tested among other variables in order to determine if certain entitling belief systems had a relationship with sexual violence.
Established instruments that measured narcissism, Machiavellianism and sexual aggression were administered to a sample of 308 male students. The subjects were also asked if they participated in collegiate athletics or fraternities, as well as their ages, sexual experience and number of credits earned in college. The results were analyzed via descriptive statistics, comparison of means, correlations, and regression. These results indicated that high sexual aggressors tended to be high in narcissism, Machiavellianism and sexual experience. Age was also positively correlated with sexual aggression. However, these variables did not contribute or explain sexual aggression, they were merely associated with it. The other variables were unrelated to sexual aggression.
This study indicates that certain personality structures might be associated with sexual aggression, and that these should be further investigated to develop a greater understanding of the causes of this criminal activity. Men who report high sexual experience may also tend to be more sexually aggressive because of their self-serving cognitions.
