A diagnosis of gender dysphoria remains the primary requirement for transgender people to receive medical and legal gender affirmation services. Three focus groups conducted in 2018 with transgender and gender diverse (TGD) adolescents were assessed to understand how they define and use the term dysphoria and how the clinical discourse of gender dysphoria relates to their sense of self and overall wellness. The 21 participants (age 12-18) were primarily White (n = 19, 90%; Hispanic n = 2, 10%). Thirteen adolescents had a masculine identity, 2 feminine, and 6 genderqueer/nonbinary. TGD youth understood the clinical definition of gender dysphoria but expanded its use; reported stigma as the cause of some of their dysphoria; and used their conceptualization of dysphoria to find self-acceptance. This study highlights the perceived harm and potential limitations of using diagnostic language to define identity. However, through rescripting and self-definition, TGD youth exercise personal agency and reject stigma.
