INTERNATIONAL TRAUMA QUESTIONNAIRE
A Valid and Reliable Measure of ICD-11 PTSD and Complex PTSD
The International Trauma Questionnaire (ITQ) is a brief, simply-worded measure, focusing only on the core features of PTSD and CPTSD, and employs straightforward diagnostic rules. The ITQ was developed to be consistent with the organizing principles of the ICD-11, as set forth by the World Health Organization, which are to maximize clinical utility and ensure international applicability through a focus on the core symptoms of a given disorder.
The ITQ is freely available in the public domain to all interested parties. Evaluation of the measure continues particularly as it relates to the definition of functional impairment for both PTSD and CPTSD and possibly the content of the items as they might relate to being predictive of differential treatment outcomes.
