PTSD Test (PCL-5)

PTSD is diagnosed by a qualified professional, such as a clinical psychologist or psychiatrist, through a clinical interview. They look at whether you went through a traumatic event and whether symptoms such as intrusive memories, avoidance and feeling on edge have lasted more than a month and affect daily life.

This usually refers to the original PTSD Checklist (PCL), which had 17 questions based on an older version of the diagnostic manual. The PCL-5 used on this page is the updated version with 20 questions, matched to the current DSM-5 criteria.

The DSM-5 groups PTSD symptoms into four areas: reliving the event through memories, nightmares or flashbacks; avoiding reminders of it; negative changes in thoughts and mood; and changes in arousal, such as feeling on guard or being easily startled.

Yes. Trauma-focused therapies have good evidence for reducing PTSD symptoms, and many people improve a great deal. Speaking to a professional trained in trauma is the best place to start.

Scores range from 0 to 80. A score of 31 to 33 or higher is often used to suggest that a full assessment for PTSD may be helpful. A score is not a diagnosis, and you can stop the test at any point if it feels like too much.
