The development of reliable and valid measures is a major challenge for gender-related research. Nonetheless, it is a necessary effort to undertake in order to assess gender inequalities accurately and pinpoint explanatory variables. Drawing on a social-psychological perspective that underscores the role of attitude, identity, and individual experience in examining gender issues, the present paper provides a brief review of the measures most commonly used to assess sexism, gender identity, and perceived gender-based discrimination. In addition, we offer suggestions for short measurement scales with the hope that sexism, gender identity, and gender discrimination can be included more extensively in large-scale opinion surveys.
