Validez de las categorías relacionadas con la identidad de genero en la CIE-11 y el DSM-5 entre personas transgenero que buscan procedimientos medicos que afirmen su genero

BACKGROUND/OBJECTIVE : The most recent versions of the two main mental disorders classifications-the World Health Organization's ICD-11 and the American Psychiatric Association's DSM-5-differ substantially in their diagnostic categories related to transgender identity. ICD-11 gender incongruence (GI), in contrast to DSM-5 gender dysphoria (GD), is explicitly not a mental disorder; neither distress nor dysfunction is a required feature. The objective was compared ICD-11 and DSM-5 diagnostic requirements in terms of their sensitivity, specificity, discriminability and ability to predict the use of gender-affirming medical procedures. METHOD : A total of 649 of transgender adults in six countries completed a retrospective structured interview. RESULTS : Using ROC analysis, sensitivity of the diagnostic requirements was equivalent for both systems, but ICD-11 showed greater specificity than DSM-5. Regression analyses indicated that history of hormones and/or surgery was predicted by variables that are an intrinsic aspect of GI/GD more than by distress and dysfunction. IRT analyses showed that the ICD-11 diagnostic formulation was more parsimonious and contained more information about caseness than the DSM-5 model. CONCLUSIONS : This study supports the ICD-11 position that GI/GD is not a mental disorder; additional diagnostic requirements of distress and/or dysfunction in DSM-5 reduce the predictive power of the diagnostic model.Partially funded by unrestricted grants by the World Health Organization Department of Mental Health and Substance Abuse to participating institutions in Brazil, India, Lebanon, Mexico, and South Africa for the development and implementation of ICD-11 field studies. Financial support for the French study was provided by the Direction Générale de la Santé (DGS), Ministry of Health, France.http://www.elsevier.es/ijchpam2023Psychiatr
