Abstract:
Mental health disparities exist for sexual minority populations globally. Microaggressions and microaffirmations related to sexual orientation may negatively or positively impact well-being. Culturally validated tools are needed to assess these constructs among LGBQ+ (lesbian, gay, bisexual, queer/questioning) individuals in Thailand's high-context culture. This study aimed to develop and validate the Thai Sexual Orientation Microaggressions Scale (T-SOMG) and the Thai Sexual Orientation Microaffirmations Scale (T-SOMF) to quantify experiences among LGBQ+ Thais. A mixed-methods approach was utilized. Initial scale items were derived from a literature review, expert consultation, and interviews with LGBQ+ Thais. Exploratory factor analysis (n = 164) refined the item pools. Confirmatory factor analysis (n = 200) confirmed the factor structures. Reliability and validity were examined. The final 18-item T-SOMG contained two subscales-Interpersonal and Environmental Microaggressions. The 13-item T-SOMF contained Interpersonal and Environmental Microaffirmations subscales. All scales demonstrated good model fit, reliability, convergent validity, and discriminant validity. The T-SOMG and T-SOMF are culturally valid tools for assessing microaggressions and microaffirmations among LGBQ+ Thais. These localized scales can enable research on factors impacting LGBQ+ well-being. Further validation in diverse samples is warranted.
