Validation of Two Measures of Gender Dysphoria/Incongruence in Transgender and Cisgender Populations in China.

This study examined gender dysphoria (GD) in transgender and cisgender populations in China and aimed to provide validity evidence for two dimensional measures of GD. A total of 293 transgender people (170 transmen, 65 transwomen, and 58 non-binary trans people; mean age, 21.3 years) and 538 cisgender people (296 ciswomen and 242 cismen; mean age, 23.5 years) completed the Utrecht Gender Dysphoria Scale (UGDS), the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA), and demographic information online. The UGDS and the GIDYQ-AA had good reliability and validity for the Chinese population. Transgender people reported higher intensity of GD than cisgender people. Cisgender women reported higher intensity of GD than cisgender men. Non-binary transgender people reported lower intensity than binary transgender people. However, transmen reported higher intensity than transwomen for the UGDS but not for the GIDYQ-AA. Transgender people with gender-affirming hormonal treatment experience reported higher intensity of GD than those without treatment. Moreover, transgender people coming out to parents reported higher intensity than those who did not. The cutoff values of the UGDS and the GIDYQ-AA in the original version show high sensitivity for transgender people and specificity for cisgender people. Our findings indicate that the UGDS and the GIDYQ-AA are validated measures of GD in China.
