The International Trauma Questionnaire: development of a self‐report measure of ICD‐11 PTSD and complex PTSD
Open accessAbstract
Objective: The purpose of this study was to finalize the development of the International Trauma Questionnaire ( ITQ ), a self‐report diagnostic measure of post‐traumatic stress disorder ( PTSD ) and complex PTSD ( CPTSD ), as defined in the 11th version of the International Classification of Diseases ( ICD ‐11). Method: The optimal symptom indicators of PTSD and CPTSD were identified by applying item response theory ( IRT ) analysis to data from a trauma‐exposed community sample ( n = 1051) and a trauma‐exposed clinical sample ( n = 247) from the United Kingdom. The validity of the optimized 12‐item ITQ was assessed with confirmatory factor analyses. Diagnostic rates were estimated and compared to previous validation studies. Results: The latent structure of the 12‐item, optimized ITQ was consistent with prior findings, and diagnostic rates of PTSD and CPTSD were in line with previous estimates. Conclusion: 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.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
