The self-confidence and sex role identities of 437 American female and male managers were examined by using three subscales of the Adjective Check List. Results showed that, contrary to stereotypes and older research, female and male managers were strikingly similar. Women and men with cross-sex role identities showed lower levels of self-confidence than those did with androgynous orientations; high self-confidence was linked with masculine and androgynous orientations. The managers were not significantly different in self-confidence when demographic variables and sex role identity were held constant. Sex role identity (but not gender) was a major factor in the level of self-confidence.
