Test for PTSD or Acute Stress Disorder in Less Time


The DAPS is a self-report instrument that assesses peri- and posttraumatic symptoms and associated features related to a specific traumatic event. It provides a detailed assessment of PTSD in a short amount of time.

Features and benefits

  • A 104-item measure, the DAPS generates a tentative diagnosis of PTSD or acute stress disorder in considerably less time than is required for a structured diagnostic interview. This diagnosis can then be confirmed by a clinical interview.
  • Assesses both current and lifetime history of DSM-IV-TR trauma exposure and the severity and clinical significance of the client’s posttraumatic symptoms, including dissociative, cognitive, and emotional responses.
