This is the basic protocol used to determine whether someone has gender dysphoria (that is, distress related to being transgender). It's excerpted from WPATH's Standards of Care
, pp. 23-24.
Mental health professionals assess clients' gender dysphoria in the context of an evaluation of their psychosocial adjustment (Bocktin et al., 2006; Lev, 2004, 2009). The evaluation includes, at a minimum, assessment of gender identity and gender dysphoria, history and development of gender dysphoric feelings, the impact of stigma attached to gender nonconformity on mental health, and the availability of support from family, friends, and peers (for example, in person or online contact with other transsexual, transgender, or gender nonconforming individuals or groups). The evaluation may result in no diagnosis, in a formal diagnosis related to gender dysphoria, and/or in other diagnoses that describe aspects of the client's health and psychosocial adjustment. The role of mental health professionals includes making reasonably sure that gender dysphoria is not secondary to or better accounted for by other diagnoses.
