[Factor analysis of 2 sex role inventories: a sample of Mexican workers].

Separate factor analyses of a Spanish version of the Bem Sex Role Inventory and of New Sex Role Scales (Positive and Negative Masculinity and Femininity), for 82 Mexican workers, yielded four interpretable factors for the BSRI, two related to feminine aspects and two to masculine ones. For the New Scales, three factors could be interpreted: a negative masculine, a negative feminine and a positive masculine-feminine. These results provide evidence which gives substantial support to the construct validity of both instruments. The present results are further compared with previous findings related to Mexican, and foreign samples as well, and discussed in relation to the concepts of masculinity and femininity.
