Mainly because it was a poorly done study that appears politically motivated and in line with other bigotry disguised as legitimate scientific studies produced in the past by people like Paul McHugh and Janice Raymond.

Recent study uses parental surveys to examine ‘rapid-onset gender dysphoria’ in transgender youth

On Aug. 22, the University published a press release on the first-ever research study to investigate “rapid-onset gender dysphoria,” which was authored by Lisa Littman, assistant professor of the practice of behavioral and social sciences in the School of Public Health. Littman’s study proposed that online forums and social media have allowed transgender identities to spread among adolescents in a manner dubbed “social contagion.” Five days later, PloS ONE, the peer-reviewed journal which published the study, posted a comment on the online paper indicating that the journal would “seek further expert assessment on the study’s methodology and analyses.” The same day, Aug. 27, Brown removed the press release highlighting Littman’s findings from its website and news distribution.
The following day, Dean of the School of Public Health Bess Marcus issued a letter affirming the School’s commitment to both academic freedom and the well-being of sexual and gender minority populations. A recent petition supporting Littman’s research and calling on both Brown and PloS ONE to “resist ideologically-based attempts to squelch controversial research evidence” has garnered 3,926 signatures, as of press time.
Methodology and data collection
Gender dysphoria is defined by the American Psychiatric Association as a conflict between a person’s physical or assigned gender and the gender with which they identify. Littman’s study defined a new form of this phenomenon, “rapid-onset gender dysphoria,” which takes place when “gender dysphoria is observed to begin suddenly during or after puberty in an adolescent or young adult who would not have met criteria for gender dysphoria in childhood.” In the study, Littman gathered data by posting a survey that asked parents about their transgender teens on three parenting websites focused on transgender adolescents.
Littman declined a request for comment.
“The three websites (that Littman posted to) all have ties (to) organizations and people that promote conversion therapy and reject gender identity,” wrote Brynn Tannehill, who has written widely about transgender experiences, including her own, in a follow-up email to The Herald. “The fact that she did not acknowledge the bias of these websites, and the effects that this would have on the data, clearly distorts whatever conclusions you may find. That’s flat-out bad research,” she said.
Multiple other experts interviewed for this article agreed with Tannehill, adding that it was unfair to draw conclusions about transgender adolescents and their experiences based on parent experiences.
