What it measures
The ITQ was developed by an international group of trauma researchers for the ICD-11. It has 18 questions: six about PTSD symptoms (upsetting memories and dreams, avoidance, feeling on guard), six about the difficulties that go with complex PTSD (strong emotions, a negative view of yourself, trouble staying close to people) and six about how these problems affect your life. Before you start, bring to mind the experience that troubles you most; you do not need to write it down. There is no total score: the authors advise using their own algorithm, so the result shows whether your answers match the pattern of PTSD or complex PTSD.
This is not a diagnosis
The ITQ shows whether your answers match the pattern of PTSD or complex PTSD. Only a specialist can say what is behind them, after a conversation and an assessment. Many reactions to trauma are treatable.
