Gender dysphoria according to wikipedia is
[T]he distress a person experiences as a result of the sex and gender they were assigned at birth. In these cases, the assigned sex and gender do not match the person's gender identity, and the person is transgender.
Other sources, such as WebMD and the APA basically agree that people with gender dysphoria
[F]eel strongly that their gender does not match their biology.
Is there a test that measures gender dysphoria? I am interested in making an adaptation to such a test into Spanish.
