Notes when administering the tool This tool is intended to be used with Turkish populations who have experienced trauma. The tool was culturally adapted and validated among populations who were affected by the Izmit earthquake in 1999. Anyone who speaks and writes in Turkish is able to administer the tool.

Excerpted from an online guide on scoring with the tool, “There are 4 columns in the scale. The first column denoted ‘not at all’ is scored as 0, the second ‘slightly’ as 1, the third ‘fairly’ as 2, and the forth ‘very much’ as 3. The first 17 symptoms of the scale represent PTSD. A score of 25 or more on this part means that the person is likely to have PTSD. The remaining 6 symptoms are depression symptoms and a
score of 38 or more on all items – all 23 – means that the survivor is likely to have
depression co-morbid to PTSD. Please note that with this scoring method it is not
possible to make a diagnosis of depression without PTSD.”
