Summary

Researchers at a gender clinic in Bari, Italy, checked 118 adults with gender dysphoria for dissociation, which means feeling cut off from your body, yourself or your surroundings. They used a clinical interview and a questionnaire, then checked again after hormone treatment and, for some, surgery. About 3 in 10 met criteria for a dissociative disorder. These patients more often had a history of depression, suicide attempts and childhood trauma. Dissociation was lower after treatment. The authors suggest that some of this "dissociation" may really be part of distress about one's body, and that standard tests struggle to tell the two apart. The high rates point to complex needs when people are first assessed. But the improvement comes from one clinic, with no comparison group and short follow-up, so it cannot show that treatment caused it.

Key findings

  • 118 adultes atteints de dysphorie de genre (82 nés hommes, 36 nées femmes) suivis dans une clinique du genre de Bari, en Italie, ont été évalués.
  • 29,6 % (environ 3 sur 10) répondaient aux critères d'un type de trouble dissociatif lors d'un entretien clinique ; un seul patient (0,8 %) répondait aux critères du trouble de personnalité multiple.
  • 45,8 % avaient connu une dépression majeure à un moment donné, 21,2 % avaient fait une tentative de suicide, et 45,8 % rapportaient un traumatisme dans l'enfance.
  • La dépression, les tentatives de suicide et les traumatismes de l'enfance étaient tous plus fréquents chez les patients ayant un trouble dissociatif.
  • Les patients rapportaient moins de dissociation au suivi après les hormones du sexe opposé et, pour certains, la chirurgie.
  • Les auteurs soutiennent que la détresse face à son corps recoupe la dissociation, si bien que les tests actuels peinent à les distinguer.
  • Les patients faisaient partie du même programme de recherche de Bari qui a produit les articles des auteurs de 2013 et 2014 sur le traitement hormonal.

Abstract

This study evaluated dissociative symptomatology, childhood trauma and body uneasiness in 118 individuals with gender dysphoria, also evaluating dissociative symptoms in follow-up assessments after sex reassignment procedures were performed. We used both clinical interviews (Dissociative Disorders Interview Schedule) and self-reported scales (Dissociative Experiences Scale). A dissociative disorder of any kind seemed to be greatly prevalent (29.6%). Moreover, individuals with gender dysphoria had a high prevalence of lifetime major depressive episode (45.8%), suicide attempts (21.2%) and childhood trauma (45.8%), and all these conditions were more frequent in patients who fulfilled diagnostic criteria for any kind of dissociative disorder. Finally, when treated, patients reported lower dissociative symptoms. Results confirmed previous research about distress in gender dysphoria and improved mental health due to sex reassignment procedures. However, it resulted to be difficult to ascertain dissociation in the context of gender dysphoria, because of the similarities between the two conditions and the possible limited application of clinical instruments which do not provide an adequate differential diagnosis. Therefore, because the body uneasiness is common to dissociative experiences and gender dysphoria, the question is whether dissociation is to be seen not as an expression of pathological dissociative experiences but as a genuine feature of gender dysphoria.

Conclusion

Results confirmed previous research about distress in gender dysphoria and improved mental health due to sex reassignment procedures. However, it resulted to be difficult to ascertain dissociation in the context of gender dysphoria, because of the similarities between the two conditions and the possible limited application of clinical instruments which do not provide an adequate differential diagnosis. Therefore, because the body uneasiness is common to dissociative experiences and gender dysphoria, the question is whether dissociation is to be seen not as an expression of pathological dissociative experiences but as a genuine feature of gender dysphoria.
