Measurement Invariance of Psychological Distress, Substance Use, and Adult Social Support Across Race/Ethnicity and Sex Among Sexual Minority Youth

Research on intersectional differences among sexual minority youth (SMY) relies on population-level datasets to ensure sufficiently large samples to explore between-group differences and assess the influence of axes of oppression/privilege. I argue that a structural equation modeling framework for investigating intersectional differences among SMY increases the nuance with which we understand heterogeneity and provides tools for ensuring that variables measure comparable constructs across diverse populations - an assumption of traditional univariate methods that is rarely empirically verified. Using a subset of SMY that identified as either White or Hispanic/Latino and male or female from the New Mexico Youth Risk and Resiliency Survey (N = 3,654), this study tested invariance of three latent constructs: psychological distress, substance use, and adult support across sexual orientation, race/ethnicity, sex, and three-way intersections of those identities. Analyses established invariance across race/ethnicity and sex of all constructs among gay/lesbian youth. Partial invariance models were required to account for intersectional differences in substance use among bisexual youth and in psychological distress among questioning youth. This study models a novel strategy for examining how social location at the intersection of multiple axes of oppression/privilege shape behavioral health and social support and paves the way for significant advances in research on SMY.
