18 questions about the experience that troubles you most. The topic is sensitive: you do not need to describe the event, and you may stop at any time. The result is a profile of symptom clusters and a screening indicator, not a diagnosis.
The International Trauma Questionnaire by Cloitre and colleagues (2018) measures the core symptoms of post-traumatic stress disorder and complex PTSD as defined in ICD-11. PTSD includes re-experiencing, avoidance and a sense of current threat; complex PTSD adds disturbances in self-organisation: affective dysregulation, negative self-concept and disturbances in relationships.
How scoring works
Answers score 0–4. Each of the six clusters is the sum of two items, 0–8; the PTSD and self-organisation totals are 0–24. The screening indicator follows the official ITQ algorithm: a cluster is met when at least one of its two items scores 2 or more, and impact is met when at least one of three impact items scores 2 or more. Complex PTSD takes precedence over PTSD.
