Measurement invariance of the LGBT People of Color Microaggressions Scale among LGBTQ+ 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.
