Abstract
Bases for the elaboration of social indicators model of sex gender stereotypes. Three ways of approaching the elaboration of gender-stereotypes indicators are proposed. The first points to role-stereotypes, drawing upon a modification of Moya and colls. Questionnaire of Sex-Role Ideology (1990). The second is based on trait-stereotypes, using the results of research by López (1991). Finally, Implicit Theories about women are considered, along the lines developed by Rodríguez and González (1987). These implicit theories summarize the reasons for the maintenance and change of this kind of stereotypes.
