Professors right the paper on the psychological advantages of "gender-affirming" operations
Two professors who published an article last year on the psychological benefits of "gender-affirming" surgery have revised their original findings.
The population study, published in the American Journal of Psychiatry last October, was conducted by John Pachankis, Associate Professor at the Yale School of Public Health, and Richard Bränström, Associate Professor at the Karolinska Institute in Sweden.
They analyzed the mental health of 1,018 Swedes who were diagnosed with "gender incongruence" between 2005 and 2015 and who had surgery to remove their genitals or make other physical changes to their appearance.
The professors concluded that patients who subsequently underwent "gender-affirming" surgery saw an 8% decrease in mood and anxiety disorders year over year.
This led the researchers to conclude that public policy should support such operations.
"In this first overall population study of transgender people diagnosed with gender incongruity, the longitudinal cut between gender-affirming surgery and decreased likelihood of psychiatric treatment supports the decision to offer gender-affirming surgery to transgender people who are looking for them." they claimed.
However, the researchers were forced to re-examine their original conclusions after the journal received letters questioning the statistical methodology used in the study.
In the correction, they now come to the conclusion that their recommendation on public order was "too strong".
"Upon request, the authors reanalyzed the data to compare outcomes between people diagnosed with gender incongruity who had received gender-affirming surgery and those diagnosed with gender incongruity who had not," the correction says.
"While this comparison was done retrospectively and was not part of the original research question because various other factors may differ between groups, the results showed no benefit of surgery in terms of subsequent visits or prescriptions related to mood or anxiety disorders health care or hospital stays after suicide attempts in this comparison.
"Given that neither a prospective cohort design nor a randomized controlled trial design was used in the study, the conclusion that the longitudinal association between gender-affirming surgery and reduced use of psychiatric treatments supports the decision to perform gender-affirming surgery for transgender people support people who are looking for them are too strong.
