Psychotraumatology: rich in international and cross-cultural collaboration.

Although European countries differ widely in their approach to psychotrauma and its consequences, with 20 years of European psychotraumatology in the form of the European Society for Traumatic Studies (ESTSS) there is now increasing dissemination of evidence-based care reaching more and more professionals and scholars in Europe. The society has moved forward to become a European umbrella organization serving many different European countries and cultures. This article describes the process of the restructuring and how ESTSS has grown from collaboration with other traumatic stress partners inside and outside Europe. The knowledge generated by The European Network for Traumatic Stress (TENTS) project has helped this process as well as the creation of an international open-access journal, the European Journal of Psychotraumatology (EJPT), for optimal dissemination of knowledge.
