Introduction: The Genderqueer Identity Scale (GQI; McGuire et al., this issue)–a newly developed and validated measure–assesses genderqueer identity via four subscales: challenging the gender binary, the extent to which participants actively work to dismantle gender binaries in identity and expression); social construction of gender, or the degree to which participants interpret their gender identity as something that develops versus an innate essentialist phenomenon; theoretical awareness of gender, the degree of social and political intention attached to gender identity; and gender fluidity, or repeated shifting of gender expression across periods of time. Aim: This descriptive study examined the predictive validity of the GQI and group differences in genderqueer identity with a sample of transgender, genderqueer and nonbinary spectrum, and cisgender sexual minority adults (N = 510). Methods: We hypothesized that Genderqueer Non-binary (GQNB) participants would score higher on GQI subscale scores compared to transgender participants who identify within the gender binary. Results: Results from ANOVA models indicated a statistically significant difference in intrapersonal subscales across sexual minority and transgender binary or genderqueer groups. For the interpersonal subscales there were differences across all three groups. Cisgender sexual minority participants reported the lowest levels on all scales, while genderqueer participants reported the highest, and transgender binary were in-between. Discussion: The GQI demonstrates strong predictive validity in distinguishing binary transpersons from GQNB and cisgender sexual minority persons. Findings reveal that these three subgroups who might otherwise be similarly categorized (i.e., LGBTQ) show significant differences on challenging the binary, social construction, theoretical awareness, and gender fluidity constructs.
