"Brief screening instrument for post-traumatic stress disorder."
I➜The Trauma Screening Questionnaire is a brief self-report trauma screening tool, simple to administer and score, designed for trauma victims in general. The TSQ is a 10-items scale, all derived from the DSM-IV2 criteria and describes either a reexperiencing symptom of post-traumatic stress disorder (items 1 through 5) or an arousal symptom of PTSD (items 6 through 10).
The result of the original study indicate that an excellent prediction of a PTSD diagnosis was provided by respondents endorsing at least 6x re-experiencing or arousal symptoms, for each sample of patients (rail crash survivors and crime victims).
