Measurement invariance of the LGBT People of Color Microaggressions Scale among LGBTQ plus youth

The LGBT People of Color Microaggressions Scale (LGBT-PCMS) is a widely used measure of intersectional microaggression experiences among sexual and gender minority people of color. Although it is widely used-and increasingly used in adolescent and young adult samples-it is unknown whether the LGBT-PCMS demonstrates similar measurement properties across subgroups of sexual and gender minority youth of color (SGMYOC). Among 4142 SGMYOC (ages 13-17) we found evidence for either partial or full scalar invariance (item loadings and intercepts were generally equal) across sexual orientation, race-ethnicity, and gender identity groups for all three subscales. Specific patterns of invariance and noninvariance across groups, as well as implications for the use of the LGBT-PCMS and its subscales among SGMYOC are discussed.
