The Gender Minority Youth Study: Overview of Methods and Social Media Recruitment of a Nationwide Sample of U.S. Cisgender and Transgender Adolescents.

Recent research has documented significant mental health disparities for transgender adolescents. However, the extant literature is hindered by vague operationalizations of gender identity and limited measurement of trans-specific stressors. In this article, we (1) introduce and describe the Gender Minority Youth (GMY) Study, a large-scale study of transgender youth disparities; and (2) provide evidence of the feasibility of using social media to recruit a diverse sample of U.S. transgender and cisgender youth. Facebook and Instagram advertisements targeted 14-18-year-old adolescents to complete an online survey. Participants (N = 3318) self-reported gender assigned at birth and current gender identity, mental health symptoms, and transgender-specific stressors and milestones. Adolescents included 1369 cisgender (n = 982 cisgender female; n = 387 cisgender male), 1938 transgender (n = 986 transgender male; n = 132 transgender female; n = 639 nonbinary assigned female at birth; n = 84 nonbinary assigned male at birth; n = 84 questioning gender identity assigned female at birth; n = 13 questioning gender identity assigned male at birth), and 11 intersex youth. The GMY Study is the first nationwide sample of U.S. adolescents recruited specifically for a study of mental health disparities between transgender and cisgender youth. We demonstrate the feasibility of using social media advertisements and a waiver of parental permission to recruit a large sample of adolescents, including subsamples of gender minority youth. We remedied limitations in the existing literature by including appropriate measures of gender assigned at birth, current gender identity, and detailed questions about transgender-specific stressors and transition milestones.
