Instruments published by Foundation Centrum ’45

Foundation Centrum '45, partner in the Arq Psychotrauma Expert Group, publishes different resources and instruments that are relevant for trauma research and the psychological evaluation of people with (complex) psychotrauma symptoms as a result of experiencing shocking events.

A part of these instruments is aimed at assessing the experienced (possibly traumatic) events and posttraumatic stress responses (including dissociative symptoms and traumatic grief) and at determining the diagnosis of Posttraumatic Stress Disorder (PTSD) in adults.

Another part of the instruments focusses on the inventory of stressful life events, posttraumatic stress responses and symptoms in unaccompanied minor asylum seekers (AMAs) who are living in the Netherlands and other refugee populations.

In addition, you will find several other measurement instruments that are relevant for research and the routine outcome monitoring (ROM) of adults.

The available translations of the instruments are shown.


It is important that only experts use these instruments in order to ensure the integrity of the person who administers them. For this reason, we ask users (administrators) of the questionnaires to register with us. Once you have registered, you will receive an e-mail stating your user name and password. These can be used to log in to the instruments and additional documentation in Adobe Acrobat Reader (*.pdf) format.
