Adolescent sex-role orientation and ego identity.

This study investigated the relationship between sex-role development and ego development in a sample of 9th-12th grade Anglo-American and Mexican-American students attending high school in a southwestern state. All students were administered: (a) the Extended Objective Measure of Ego Identity Status (Grotevant and Adams, 1984) as a measure of ego development (i.e., diffusion, foreclosure, moratorium, and identity achievement), and (b) the Personal Attributes Questionnaire Short Form (Spence, Helmreich and Stapp, 1975) as a measure of masculinity and femininity. Results indicated no ethnic differences in the relationship between ego identity and masculinity/femininity. Adolescents who were identity achieved on ideological identity formation had significantly higher levels of masculinity than did moratorium, foreclosed, and diffused individuals. For interpersonal identity, identity achieved adolescents had higher levels of both masculinity and femininity than did individuals who were foreclosed, diffused, or in moratorium. Discussion centered on these results in light of the additional finding that there was little shared variance (eta2) between masculinity, femininity and ego identity.
