What is the PSS-SR5?
The PTSD Symptom Scale – Self-Report for DSM-5 (PSS-SR5) was developed by Professor Edna Foa and colleagues at the University of Pennsylvania. It measures the symptoms of post-traumatic stress disorder (PTSD) as described in DSM-5, the diagnostic manual used by mental health professionals.
Its 20 questions cover the four groups of PTSD symptoms: re-experiencing (unwanted memories, nightmares, flashbacks), avoidance of reminders, negative changes in thoughts and mood, and changes in arousal and reactivity such as irritability, poor sleep and feeling on guard. Each is rated from 0 to 4, giving a total from 0 to 80. A total of 28 or more is the research cut-off suggesting probable PTSD.
Who should take it?
The PSS-SR5 is for adults who have lived through, witnessed or been repeatedly exposed to a frightening or distressing event — for example an accident, assault, abuse, war, a serious illness or a disaster — and who are still affected by it.
How to take it
Before you start, bring to mind the one traumatic event that bothers you most now. Then, for each statement, choose how often it has happened and how much it has bothered you during the past month. Take your time and pause if you need to — it takes about ten minutes.
Frequently asked questions
Does this test diagnose PTSD?
No. It is a screening and severity measure. Only a qualified professional can diagnose PTSD after a full assessment, which also considers how long symptoms have lasted and how they affect your life.
What if answering the questions upsets me?
That is a common reaction. You can stop at any time, take a break, and come back later. If you feel overwhelmed, reach out to someone you trust or one of our therapists.
Can PTSD be treated?
Yes. Trauma-focused therapies, such as prolonged exposure and cognitive processing therapy, are effective for many people, even years after the event.
