Previous research studies have indicated that intergroup contact between heterosexuals and lesbian, gay, and bisexual (LGB) individuals has been associated with more positive feelings about and understanding of the LGB community. The current study examined how closeness of that intergroup contact between heterosexual, cisgender students and lesbian, gay, bisexual, transgender, and queer (LGBTQ) peers would relate with LGB ally identity and behaviors. Three hundred fifty-three heterosexual, cisgender college students answered questions about their ally identity, knowledge, and behaviors. Close friendships but not coworker-acquaintance relationships with LGBTQ individuals were associated with higher LGB ally identity and behavior measure scores when compared with students who had no such relationships. In the long term, ally relationships can contribute to making the environment safer for LGBTQ people, including students, who may then feel more comfortable to come out. With more out LGBTQ people, close friendships may develop between LGBTQ people and heterosexuals, which could contribute to allyhood.
