While data from a sample of fourth-grade children indicate that both self-efficacy (masculinity) and relationality (femininity) are strongly associated with self-esteem for both girls and boys, results from a comparable sample of adolescents aged 14-18 and a subsample of the fourth graders when they were in twelfth grade indicate that only self-efficacy is generally associated with self- esteem. An association between relationality and self-esteem is found in adolescents only for a small, high-achieving, high-SES subset of ‘androgynous’ males.
