This study assesses how variations in heteronormative culture in high schools affect the well-being of same-sex-attracted youth. The authors focus on the stigmatization of same-sex attraction to better understand how heteronormativity may marginalize a wide range of youth. Specifically, the authors use data from the National Longitudinal Study of Adolescent Health to examine how variation across schools in football participation, religious attendance, and urban locale affects same-sex-attracted adolescents' depressive symptoms, self-esteem, fighting, and academic failure. The results suggest that though same-sex-attracted (...) youth are at greater risk for decreased well-being, these youth are at higher risk in nonurban schools and in schools where football and religion have a larger presence. Results vary for boys and girls: The urban locale of a school has a larger impact for boys, while school religiosity has a greater impact for girls. (shrink)
