A Scoping Review on the Role of Sexual Orientation and Gender Identity Microaggressions in Substance Use

Measuring Propensity to Perpetrate Microaggressions Toward LGBTQ Individuals: Sexual Orientation Microaggression Scale (SOMS-P) and Gender Identity Microaggression Scale (GIMS-P) Perpetration Version

This study is an initial psychometric evaluation of the Sexual Orientation Microaggression Perpetration Scale (SOMS-P) and Gender Identity Microaggression Perpetration Scale (GIMS-P). Using data from 2,059 undergraduate students (Mage = 21.37, SD = 4.98; Range 18-68; 78.6% assigned female at birth, 13.3% self-identified as sexual minority person), item factor analysis for binary indicators and model comparisons indicated that a correlated four- and five-factor solution for the SOMS-P and GIMS-P, respectively, outperformed a one-factor and higher-order solutions. SOMS-P and GIMS-P scores were positively associated with self-reports of bullying, violence perpetration, and hostile attitudes toward individuals who self-identify as sexual or gender minorities. They were negatively associated with attitudes supportive of sexual or gender minority persons. Reliability of .80 and higher was observed only for theta values between + 0.40 to + 2.60 SD. The psychometric evaluation showed that, while there remain to be opportunities to examine their validity across diverse contexts, SOMS-P and GIMS-P are sound measures of the propensity for SOGI microaggression.

Homonegativity, binegativity, and transnegativity among substance use treatment practitioners in the United States

Lesbian, gay, bisexual, and transgender (LGBT) people have an elevated risk for substance use disorder relative to heterosexual and cisgender people. Scholars have predominantly explained this disparity as resulting from LGBT people's chronic exposure to interpersonal and structural stigma and discrimination. Despite their front-line role in serving LGBT people with substance use disorder, investigations of homonegativity, binegativity, and transnegativity among substance use treatment practitioners have been limited. An online survey of 225 practitioners examined levels of homonegativity, binegativity, and transnegativity and their demographic and socio-political correlates. Levels of homonegativity were lower than those of binegativity and transnegativity. Educational attainment, connectedness to LGBT people, and having a liberal political identity were associated with lower homonegativity, binegativity and transnegativity, while religiosity was associated with higher scores in all categories. Addressing substance use treatment practitioners' stigma toward LGBT people, particularly bisexual and transgender people, should be prioritized. Substance use treatment organizations are recommended to examine how their policies and practices may perpetuate structural stigma toward LGBT people.
