A study published today finds no association between gender social transition and mental health status amongst children and adolescents referred to GIDS.
Is Social Gender Transition Associated with Mental Health Status in Children and Adolescents with Gender Dysphoria?
"We assessed mental health correlates of living in one’s affirmed gender among 288 children and adolescents (208 birth-assigned female; 210 socially transitioned) and of name change in 357 children and adolescents (253 birth-assigned female; 214 name change). The presence or absence of mood and anxiety difficulties and past suicide attempts were clinician rated. "
"Overall, there were no significant effects of social transition or name change on mental health status"
(I think they should avoid the term 'effects' since it implies causation and this is a correlational study).
