Using the MMPI, this study investigates the extent to which sex lines are diffused among college students who tend to represent the middle class. In a comparison of MMPI scores, male college students scored higher than females on all ten clinical scales with seven of these significant, indicating better adjustment in general for women. In regard to the personality traits, the men tended toward less virile characteristics--sensitive, worrisome, insecure, easily embarrassed; women tended toward more masculine characteristics--ambitious, aggressive, confident--indicating overlap of traditional sex characteristics.
