Unfortunately, few studies have examined the impact of this climate on female athletes with minoritized sexual identities. Most research pertaining to this population has been qualitative and largely focused on lesbian athletes (Fynes & Fisher, 2016; Stoelting, 2011). Consequently, more generalizable conclusions about queer female athlete experiences has been limited. The present study was an attempt to address this research gap, by assessing the internalized heterosexism, outness, athletic identity, and perceived stress of queer women competing at the college level. Two mediation models were proposed. The first situated internalized heterosexism as a mediator of the relationship between athletic identity and perceived stress. The second situated internalized heterosexism as a mediator between outness and perceived stress. Participants were recruited via online webpages and email advertisement. Only cisgender women over 18, competing in the National Collegiate Athletic Association (NCAA), and identifying with a minoritized sexual identity were eligible to participate.
