Based on Erikson's view of the importance of "inner space" in feminine identity, researchers have added an interview on premarital sex to the standard ego identity interview on occupation, religion, and politics used for males. This study was designed to investigate the relative importance of premarital sexual ideology for males and females, as well as sex differences in identity status on occupation, religion, and politics. Marcia's semi-structured ego identity status interview was given to 70 male and 70 female college students, with premarital sex questions included for both sexes. Consistent with Erikson's theory, females were more likely than males to have experienced a sexual identity crisis, whereas males were very likely to be foreclosed in this area. Males as well as females were more likely to be committed about sex than about any other area. In all areas except sex, female identity followed basically the same pattern as male identity.
