In the present paper the construct of Neosexism, as one of the new forms of sexism, and the Spanish version of the Neosexism scale (Tougas, Brown, Beaton & Joly,(1995) are presented. Using a sample of 1191 men, we tested the psychometric properties of the scale and the relationship between Neosexism and some other sociodemographic characteristics and with old-fashioned sexism, attitudes toward affirmative action and men's collective interest. Ours results show that Neosexism, a construct created in a cultural and economic context different to Spain, could be applied to a Spanish context. We also found that the Neosexism scale can be an appropriate instrument to measure modern forms of sexism, specially in organizational and work settings. A mediational analysis performed on the data suggest that, among men, neosexist beliefs influence subjective threat to collective interests, this perceived threat triggering an opposition to affirmative action programs.
