ESTD - AFTD Conference 2023

When Attachment Meets Trauma:
Disorganization and Dissociation From Childhood to Adulthood.

Preconference Workshops and Conference

DoubleTree Brussels Hotel, 9 - 11 March 2023 - Brussels


The European Society for Trauma and Dissociation was founded in April 2006. This followed a period of active planning and collaboration with professional colleagues from over 17 countries in Europe as well as with the Executive Council of the International Society for the Study of Trauma and Dissociation (ISSTD).The establishment of the European Society for Trauma and Dissociation (ESTD) was strongly supported by the ISSTD with whom we have close ties.


From the simplest to the most complex, the theme of psychic trauma has invaded many social spaces: media, professionals, scientists and of course clinics. This is why in 2015, a handful of Swiss, French and Belgian psychotherapists and researchers who are passionate about and committed to this specific clinical field created the Association Francophone du Trauma et de la Dissociation in order to meet these challenges and meet three fundamental objectives: to create links between professionals, to disseminate the most advanced and recent knowledge in the field of psychotrauma and dissociation, and promote the clinical advances related to it
