About This Assessment

Peritraumatic Dissociative Experiences Questionnaire Test

dissociation psychopathology ptsd

This self-report measure assesses dissociative experiences occurring during or immediately after a traumatic event. The Peritraumatic Dissociative Experiences Questionnaire is commonly used in early post-trauma assessment to characterize acute alterations in awareness, perception, and memory related to the event.

It consists of 9 items and typically takes about 2 minutes to complete. Items ask respondents to rate the extent to which specific dissociative reactions were present at the time of the stressor, supporting clinical documentation and risk formulation.

In clinical and research settings, the Peritraumatic Dissociative Experiences Questionnaire may be used to inform follow-up monitoring and to support evaluation of vulnerability to later trauma-related symptoms. The measure is attributed to Charles R. Marmar and John H. Briere.
