Sexism has implications for people’s physical and mental health. Thus, understanding sexism and its prevalence is key to understanding the phenomenon. In the current study, 717 Colombian men and women completed the brief scales of Ambivalent Sexism toward women and men and the Gender Identity Scale. The assessment was conducted using a web-based method. Both scales, as expected, were two-dimensional. Reliability ranged from .83 to .88. Moderate and high correlations were observed with the Gender Identity Scale. Men showed higher levels of hostile and benevolent sexism toward women and benevolent sexism toward men. It was also found that the higher the level of education, the lower the rates of sexism toward men and women. The brief scales were valid and reliable for measuring hostile and benevolent sexism in Colombia.
