Updated: Brown statements on gender dysphoria study

The revised study by Lisa Littman, assistant professor of the practice of behavioral and social sciences at Brown University, is now retitled "Parent reports of adolescents and young adults perceived to show signs of a rapid onset of gender dysphoria." It includes revisions and updates to multiple sections of the study, including the title, abstract, introduction, materials and methods, discussion and conclusion sections.

PLOS ONE published the revised study on Tuesday, March 19. In addition to the updated study, the journal included a correction / notice of republication and a separate formal comment from researcher Angelo Brandelli Costa, associate professor of social psychology at the Pontifical Catholic University of Rio Grande do Sul, Brazil.

The notice of republication from PLOS ONE states: "After publication of this article... questions were raised that prompted the journal to conduct a post-publication reassessment... involving senior members of the journal's editorial team, two Academic Editors, a statistics reviewer, and an external expert reviewer. The post-publication review identified issues that needed to be addressed to ensure the article meets PLOS ONE's publication criteria. Given the nature of the issues in this case, the PLOS ONE Editors decided to republish the article, replacing the original version of record with a revised version."
