Rapid-onset gender dysphoria controversy
Translate to English: Angelo Brandelli Costa was one of the editors of the journal PLOS ONE who participated in the post-publication review of the article by Lisa Littman on the concept of rapid-onset gender dysphoria (ROGD). This concept refers to a supposed phenomenon of sudden or rapid onset of gender dysphoria in adolescents and young adults, who did not show signs of gender incongruence in childhood, and who would be influenced by social and media factors. Littman's article, based on an online survey with parents who reported cases of ROGD in their children, was criticized by clinicians, researchers and transgender activists, who pointed out methodological and ethical problems, as well as potential harms to the trans population. In response to the criticisms, PLOS ONE announced a review of the article, which resulted in its republication with corrections and revisions in March 2019. Costa published a formal comment on Littman's article, in which he questioned the validity of the ROGD concept and the quality of the evidence presented by the author. Costa argued that Littman's study provided only indirect evidence of the role of social and media influence on the gender identity of young people, and that the sample of parents recruited from sites opposed to gender transition could bias the results. Costa also criticized the fact that the study did not include the perspective of the young people themselves who identified as transgender, and suggested that future research on the topic should involve data provided by pro- and anti-transition parents, as well as by young people with gender dysphoria.
