Brief screening instrument for post-traumatic stress disorder

Background Brief screening instruments appear to be a viable way of detecting post-traumatic stress disorder (PTSD) but none has yet been adequately validated. Aims To test and cross-validate a brief instrument that is simple to administer and score. Method Forty-one survivors of a rail crash were administered a questionnaire, followed by a structured clinical interview I week later. Results Excellent prediction of a PTSD diagnosis was provided by respondents endorsing at least six re-experiencing or arousal symptoms, in any combination. The findings were replicated on data from a previous study of 157 crime victims. Conclusions Performance of the new measure was equivalent to agreement achieved between two full clinical interviews. Declaration of interest The study was funded by the NHSE London Regional Office (project no. RDC01702).
