Political scientists are paying increasing attention to understanding the role of sexist attitudes on predicting vote choices and opinions on issues. However, the research in this area measures sexist attitudes with a variety of different items and scales. In this paper, I evaluate some of the most prominent contemporary measures of sexism and develop an approach for identifying optimal items based on (1) convergent validity, (2) predictive validity, and (3) distance from politics. I find that a subset of items from the hostile sexism scale exhibit the most desirable measurement properties and I conclude by recommending a simple two- to five-item reduced hostile sexism battery that will allow scholars to efficiently, validly, and consistently measure sexism.
