PC Science: A newly released study is angering the transgender community for concluding that most young people who ‘come out’ as trans have at least one mental disorder. In the study, which was published at PLoS ONE and focused primarily on female teens, assistant professor of behavioral and social sciences at Brown University Lisa Littman found that 87 percent of young people were reported by their parents to have come out as trans after an increased amount of time spent on social media and the Internet and after “cluster outbreaks” of gender dysphoria among groups of friends.
