Measuring LGBTQ Microaggressions: The Sexual Orientation Microaggressions Scale (SOMS) and the Gender Identity Microaggressions Scale (GIMS).

Microaggressions are brief and commonplace daily verbal, behavioral, or environmental indignities, intentional or unintentional, that demonstrate bias toward members of historically marginalized groups. While numerous quantitative studies on racial microaggressions have emerged in recent years, studies on sexual orientation and gender identity microaggressions have been mostly qualitative-likely due to limited measures of anti-LGBTQ microaggressions. In this three-part study, the Sexual Orientation Microaggressions Scale (SOMS) and the Gender Identity Microaggressions Scale (GIMS) are introduced to empirically explore the multifaceted experiences of microaggressions toward lesbian, gay, bisexual, and queer (LGBQ) people and transgender and gender nonconforming (TGNC) people. In Study 1 (N = 260), a principal components analysis yielded a five-factor structure of sexual orientation microaggressions; in Study 2, a new sample (N = 140) is used to confirm the utility of the SOMS. In Study 3, the GIMS is piloted with a sample of TGNC participants (N = 160). Implications for future studies are discussed.
