Participants (n = 215, Mage = 20.20 years; 62% female) were asked to rate their perceived similarity to both own- and other-gender peers. They also completed questionnaires assessing sexist attitudes, internalized sexualization (females), adherence to male-typed behaviors in the context of interpersonal relationships (males; adherence to physical toughness and restrictive emotional expressivity), gender-based relationship efficacy, friendships, self-esteem, social self-efficacy, and social anxiety. Results indicated that self-perceived gender typicality involves comparisons to both gender groups, and that meaningful typologies can be created based on similarity to own- and other-gender groups. As with children, results indicated that identifying with one¡¯s own gender was advantageous in terms of low social anxiety and relationships with own-gender peers. For adults who identified with both own- and other-gender peers, we identified additional social benefits (i.e., efficacy and friendships with other-gender peers). Further, we identified a downside to own-gender typicality: individuals who identified only with their own gender had more sexist attitudes than those who identified with the other gender. Findings support the viability of the dual-identity approach in young adults, and have implications for researchers assessing gender typicality across development %K Gender typicality %K gender typicality %K young adults %K social adjustment %U https://journals.sagepub.com/doi/full/10.1177/0165025418811125
