I'm looking for the International Trauma Questionnaire (ITQ) as per ICD-11 proposals, but I can not find it. It was previously called the ICD-11 Trauma Questionnaire (ICD-TQ). Can someone help me?

    $\begingroup$ Since it's a proposal, it might not be publicly available. There are some papers about it. One cites it as "Cloitre, M., Roberts, N.P., Bisson, J. I., & Brewin, C. R. (under development). The ICD-11 Trauma Questionnaire (ICD-TQ). Unpublished Measure." $\endgroup$ – Fizz Aug 21 '18 at 2:02

You can find the ITQ at the following site that we've made for the scale:

    $\begingroup$ Also, the site title is Internationally Valid Measures" [plural] yet only 1 measure is provided. What about others? $\endgroup$ – Chris Rogers Sep 30 '18 at 8:28
  • $\begingroup$ Many thanks to Philip Hyland and Chris Rogers (@chris-rogers)! $\endgroup$ – Iurie Malai Oct 1 '18 at 4:55
  • $\begingroup$ @ChrisRogers: Philip Hyland is one of the authors of the paper you've cited in your own answer. That should make "we" obvious. $\endgroup$ – Fizz Oct 4 '18 at 22:20
  • $\begingroup$ @Fizz, ChrisRogers is simply making points about what makes for a good answer on this site. This post is a little sparse... $\endgroup$ – leanne Sep 3 '19 at 17:27

I would suggest going to the source which is Cloitre, et al. (2018)

The ITQ is a brief, simply worded measure of the core features of PTSD and CPTSD. It is consistent with the organizing principles of the ICD‐11 to maximize clinical utility and international applicability through a focus on a limited but central set of symptoms. The measure is freely available and can be found in the body of this paper.


Cloitre, M., Shevlin, M., Brewin, C. R., Bisson, J. I., Roberts, N. P., Maercker, A., ... & Hyland, P. (2018). The International Trauma Questionnaire: development of a self‐report measure of ICD‐11 PTSD and complex PTSD. Acta Psychiatrica Scandinavica. (In Press: September 2018) doi: 10.1111/acps.12956
