“…The assessment of sexual orientation has changed significantly across the different NCHA surveys. In the original NCHA-I (Spring 2000–Spring 2008), participants were asked “Which of the following best describes you?” Response options included “heterosexual,” “gay/lesbian,” “bisexual,” “transgendered,” and “unsure.” Due to the conflation of sexual orientation and transgender identity in the sexual orientation item from the NCHA-I, as well as the unique experiences of structural stigma and minority stress among gender minorities compared with sexual minorities (Hendricks & Testa, 2012; Williams et al, 2020), participants who responded “transgendered” were excluded from all analyses. In the NCHA-IIa/IIb (Fall 2008–Spring 2015), participants were asked “What is your sexual orientation?” Response options included “heterosexual,” “gay/lesbian,” “bisexual,” and “unsure.” In the NCHA-IIc (Fall 2015–Spring 2019), participants were asked “Which term best describes your sexual orientation?” Response options included “asexual,” “bisexual,” “gay,” “lesbian,” “pansexual,” “queer,” “questioning,” “same gender loving,” “straight/heterosexual,” and “another identity (please specify).” Because a substantial proportion of those who identified as “another identity” provided nonserious, mocking, or prejudicial responses, these participants were excluded from all analyses.…”
