Abstract

We investigated associations between gender segregation and the two traditions of gender identity identified by Wood and Eagly (2015): gender-typed personality traits and gender reference group identity. We also investigated whether one of these traditions was associated with gender segregation to a greater extent than the other. Our sample consisted of 73 male (and 93 female undergraduate students aged 18–24 attending a university in the northeastern United States of America. In support of our hypotheses we found that male and female college students reported a greater proportion of same-gender than cross-gender friends and that gender segregation was negatively associated with femininity for male college students and positively associated with gender reference group identity for male and female college students. In addition, as hypothesized, we found that gender reference group identity was associated with gender segregation to a greater extent than gender-typed personality traits. That gender segregation is associated with gender reference group identity to a greater extent than gender-typed personality traits supports a multifaceted model of gender, and it highlights the importance of considering different traditions of gender identity in gender research (Mehta 2015; Wood and Eagly 2015).
