Toward inclusive and equitable LGBTIQ+ measurement: Assessing gender and sexual orientation measures and scale validity in national surveys across 21 countries

Abstract

Abstract Despite growing global interest in lesbian, gay, bisexual, trans, intersex, and queer/questioning (LGBTIQ+) research, variations in measurement practices across countries have remained underexplored. In this work, we focused on two fundamental aspects of measurement vital to understanding the experiences of LGBTIQ+ people. Specifically, we documented current measures of sex, gender, and sexual orientation used in national mental well‐being‐related surveys and reviewed whether the mental well‐being scales in those surveys have been validated for LGBTIQ+ people. We employed a stratified sampling strategy and evaluated national surveys from a list of randomly selected countries representing 10% of global nations ( N = 21). Fewer than half of the countries measured sexual orientation and fewer than one‐third measured gender beyond the binary in their national surveys. Among the countries that measured gender or sexual orientation, the response options and question phrasing were often not inclusive. In addition, most of the mental well‐being scales lacked validity evidence for LGBTIQ+ populations. Finally, we outline recommendations for the future of reimagining LGBTIQ+ research in terms of measurement, highlighting the importance of research engagement with the global LGBTIQ+ community.
