The same emergency crisis unit have been activated for the terrorist attack in London, 2017 june 3, terrorist attack in Barcelone 2017 august 17-18, terrorist attack in Strasbourg 2018 December 11 The purpose of this observational study is to document the evolution of psychiatric symptoms among subjects who called the CUMP and to collect information about the type of medical or non-medical care they were seeking for.

The care of the victims of natural disasters or mass disasters such as terrorist attacks is now better structured and organized. The efficacy of debriefing or of defusing has been and is still debated, sometimes bitterly. The aim of the present study is not to demonstrate utility or futility of such approaches, but to i) evaluate their global improvement over the past three years. ii) to list the type of support that the victims were seeking in their attempt to get rid of the symptoms which appeared after the terrorist attack of November 2015 in Paris.
