Students from marginalized religious backgrounds face myriad challenges on college and university campuses, and negative effects are especially pronounced for Muslim students. Wearing hijab can put college students at a greater risk of marginalization amidst a climate of Islamophobia. Although there is a growing body of research on Muslim college student experiences, there is a more limited exploration of hijabi students' experiences. In this exploratory online survey study (n=41), we sought to understand experiences of belonging and Islamophobia among hijabi Muslim students across the United States. We adopted a critical quantitative approach, specifically interested in the connection of hijabi students' sense of belonging, social adjustment, and experiences of microaggressions to their adherence to the Islamic dress code, membership in a Muslim student organization (MSA), and identifying with a minoritized racial group. We found that more modest dress was associated with lower perceived support from peers and faculty, while reported microaggressions were negatively related to faculty empathy. The strongest effects were involvement in MSA on social adjustment, and having a white identity on perceived faculty support. This study contributes to our understanding of the role of student affairs professionals, faculty, and higher education administrators in supporting hijabi students to succeed as their whole authentic selves.
