Global Psychotrauma Screen (GPS)

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. It consists of 22 items to be answered in a yes/no format.
 
The GPS was constructed by 1) reaching consensus on the domains, including trauma-related problems but also risk and protective factors. 2) Selecting scales or items (as much as possible) from existing valid and reliable measures that were available without barriers to access.

The domains are:

  • 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 GPS is currently available in 18 languages.
