About this screener — evidence, source, alternatives
The self-report measure of ICD-11 post-traumatic stress disorder and complex PTSD, developed with the WHO ICD-11 working group's principles. Six items cover the three PTSD clusters (re-experiencing, avoidance, sense of threat) and six cover disturbances in self-organisation (affective dysregulation, negative self-concept, relationship problems), each with three functional-impairment items.
Evidence · validated
Item response theory analysis in a UK trauma-exposed community sample (n = 1051) and clinical sample (n = 247) identified the 12 optimal symptom items; CFA supported the ICD-11 latent structure, and PTSD/CPTSD rates were in line with previous estimates (Cloitre et al., 2018).
