PTSD and DSO each have a continuous 0–24 score without severity bands. The ITQ is a self-screening tool. Results, including the algorithm's criteria check, are for reference only and do not constitute a medical diagnosis — if you have concerns, please consult a clinical psychologist or doctor. In a crisis, call The Samaritans Hong Kong 24-hour hotline at 2896 0000. The ITQ is in the public domain (International Trauma Consortium, Cloitre et al. 2018). Item wording and scoring are retained; the web format omits the paper questionnaire's free-text trauma-description prompt.
