Think of the most stressful experience you have been through: the test shows how much it has bothered you over the past month. It is not a diagnosis, only a prompt to decide whether to talk to a professional.
The PCL-5 (PTSD Checklist for DSM-5) comes from the US National Center for PTSD. Its 20 questions follow the DSM-5 symptoms of PTSD: unwanted memories and nightmares, avoidance, negative thoughts and feelings, and being on edge. Each answer scores 0 to 4 points, for a total of 0 to 80.
This is not a diagnosis
A checklist cannot diagnose PTSD. A professional makes a diagnosis after a conversation about what happened and how you are doing now.
