Clinician judgment in the diagnosis of gender identity disorder in children.

Clinician judgment methodology was used to explore the influence of gender nonconformity and gender dysphoria on the diagnosis of children with Gender Identity Disorder (GID). A convenience sample of 73 licensed psychologists randomly received a vignette to diagnose. Vignettes varied across sex of child, gender conforming behavior, and gender dysphoria (including all possible permutations). Eight percent of respondents given a vignette involving a child who met purely behavioral criteria for GID diagnosed the child with GID. When additional information was provided, which in addition to gender nonconforming behavior the child also self-reported a cross-gender identity, this increased to 27% (significant at 5%).
