Perceived Stress Scale (PSS-10)

Answer 10 questions about the past month to get a stress score from 0–40. Developed by Sheldon Cohen (1983), the PSS-10 is the most widely validated self-report measure of perceived stress.

For each question, choose how often you felt or thought a certain way in the last month.

1. How often have you been upset because of something that happened unexpectedly?

2. How often have you felt unable to control the important things in your life?

3. How often have you felt nervous and stressed?

4. How often have you felt confident about your ability to handle your personal problems?

This question is positively worded — confident answers lower your score.

5. How often have you felt that things were going your way?

This question is positively worded — more often lowers your score.

6. How often have you found that you could not cope with all the things you had to do?

7. How often have you been able to control irritations in your life?

This question is positively worded — being able to control irritations lowers your score.

8. How often have you felt that you were on top of things?

This question is positively worded — feeling on top of things lowers your score.

9. How often have you been angered because of things that were outside of your control?

10. How often have you felt difficulties were piling up so high that you could not overcome them?

Frequently asked questions

What is the PSS-10 and how is this score calculated?

The Perceived Stress Scale (PSS-10) was developed by Sheldon Cohen and colleagues in 1983. It contains 10 questions about feelings and thoughts over the past month, each scored 0 (Never) to 4 (Very Often). Six items are scored directly; four positively-worded items (feeling confident, things going your way, controlling irritations, being on top of things) are reverse-scored so that higher answers lower your total. Scores range from 0 to 40.

What is a normal PSS-10 score?

Population studies report mean scores of 12–14 for community adults. Scores of 0–13 indicate low perceived stress, 14–26 indicate moderate stress, and 27–40 indicate high perceived stress. Scores above 20 have been associated with significantly elevated cortisol levels and increased susceptibility to illness in prospective studies.

Is this a clinical diagnosis?

No. The PSS-10 is a screening and research tool, not a clinical diagnostic instrument. It cannot diagnose anxiety disorders, depression, burnout, or any other condition. A high score means you are perceiving your life as stressful — a valid and important signal — but a mental health professional is needed to assess whether clinical intervention is warranted.

Can my score improve and how quickly?

PSS scores are responsive to intervention. Randomised controlled trials show that 8 weeks of Mindfulness-Based Stress Reduction (MBSR), regular aerobic exercise (3×/week), or cognitive-behavioural techniques each produce clinically meaningful reductions of 4–8 points on average. Even improving sleep consistency by 30–45 minutes can lower PSS scores within 2–4 weeks in people who are sleep-restricted.
