The goal of this investigation was to examine psychiatric symptoms as predictors of the frequency and severity of sexually aggressive behaviors that had been perpetrated by college-aged men in the past year. Over 400 undergraduate males completed an assessment of sexual aggression, athletic involvement, fraternity affiliation, alcohol and drug use, mistrust of women, depression, and social anxiety. More than 40% of the undergraduate men reported having participated in some form of sexual aggression within the past 12 months, 6% of whom reported having attempted or completed rape. Sexually aggressive behavior (both frequency and severity) was predicted by alcohol use, mistrust of women, and social anxiety. Results are the first to indicate that psychiatric symptoms might contribute to sexual aggression among college men.
