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

  • Trauma scales were normed on a sample of more than 400 respondents from the general population who reported exposure to at least one DSM-IV-level trauma in the past.
  • Validity scales help to identify individuals who, for whatever reason, over or underreport psychological symptoms.
  • Measures trauma exposure in detail. It not only evaluates the respondent’s cumulative lifetime history of DSM-IV traumatic 7 events (including experiences of childhood sexual abuse), but it also assesses his or her immediate dissociative, cognitive, and emotional responses at the time of whatever trauma is specified for evaluation.
  • Evaluates each of the three PTSD symptom clusters (reexperiencing, avoidance, and hyperarousal) in detail.
  • Generates a probable diagnosis of PTSD, in addition to measuring symptom severity.
  • Includes specific scales for three associated features of PTSD: trauma-specific dissociation, suicidality, and substance abuse. Additional information on these comorbid symptoms contributes to a more complete psychological assessment and often has direct clinical implications for the treatment of traumatized individuals.

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.
  • Do you need to screen a client or a group?  Derived from the DAPS, the PSS screens individuals for posttraumatic stress disorder (PTSD) and suicidality in under 5 minutes.
