Global Psychotrauma Screen

The Global Psychotrauma Screen (GPS) was developed by an international group of experts representing traumatic stress societies worldwide (initiated by ISTSS) called the “Global Collaboration on Traumatic Stress” (Schnyder et al., 2017).

The GPS is a brief instrument meant to screen for a range of trauma-related psychological problems, as well as for risk and protective factors. 

Please find the GPS here or go here to to participate in a cross-cultural project related to COVID-19.

The GPS is currently available in 27 languages and covers the following domains with 22 yes/no questions:

  • PTSD
  • Complex PTSD
  • Anxiety
  • Depression
  • Sleep problems
  • Self-injurious behavior
  • Dissociation
  • Other physical, emotional or social problems
  • Substance abuse
  • Other stressful events
  • Childhood trauma
  • History of mental illness
  • Social support
  • Psychological resilience

The first data show that the GPS is a reliable and valid instrument (Olff et al., 2020). Normscores will be published on the Global Collaboration on Traumatic Stress website.

Get more information or participate in research with the GPS.
