Transcultural Validation of the Global Psychotrauma Screen

Study Information
Purpose of Study
The Global Psychotrauma Screen (GPS) was developed by an international group of experts representing traumatic stress societies worldwide, called the Global Collaboration on Traumatic Stress (Olff et al., 2020; Schnyder et al., 2017) with the aim to address the need for a brief instrument that would tap potential (long term) consequences of (child) trauma, broader than Posttraumatic Stress Disorder symptoms. It can be applied to tap the consequences of all types of trauma including more recent events. We are currently recruiting Canadian participants to validate the GPS with Canadians and develop Canadian norms.

What You'll Be Asked to Do:
The Global Psychotrauma Screen (GPS) consists of 22 items, each to be answered in a yes/no format. The GPS is currently available in 23 languages. Participants will be invited to complete this questionnaire (approx. 5 minutes). For the purpose of collecting norm data, participants' anonymous responses will be saved to a secure server. If the results are published, only group-averaged results will be published; participants' personal results or any identifying information will not be published. Results will be kept for a minimum of 15 years. Participants may leave the survey at any time simply by exiting the computer application, and may also refuse to answer any question you do not want to answer. The questionnaire should take approximately 5 minutes.
