Perceived Stress Scale score: what your PSS-10 result means

A Perceived Stress Scale (PSS-10) score runs from 0 to 40 and shows how unpredictable, uncontrollable and overloaded life has felt to you over the last month. There are no official cut-offs, so no score is “normal” or “high” by definition. Sprout describes results in rough thirds of the range: 0 to 13 mostly manageable, 14 to 26 some pressure and 27 to 40 a lot of pressure. The most useful way to read your score is against your own earlier ones, and it’s never a diagnosis.

What is the Perceived Stress Scale?

The Perceived Stress Scale is the most widely used questionnaire about how stressed people feel. Psychologist Sheldon Cohen and colleagues at Carnegie Mellon University published the original version in 1983, in the Journal of Health and Social Behavior. The 10-question version, the PSS-10, followed in 1988, when Cohen and Gail Williamson used it in a large sample of adults across the United States.

Unlike earlier stress checklists, it asks how stress feels rather than counting events such as moving house, losing a job or a death in the family. Cohen’s team noticed that the same event weighs very differently on different people. Instead of counting events, the scale asks how often life has felt unpredictable, out of your control or more than you can handle. That’s why it’s called perceived stress.

The stress test on Sprout uses the PSS-10 and takes about three minutes. Taking the test is free; results need Sprout Plus (7 days free).

How is a PSS-10 score worked out?

To calculate a PSS-10 score, score each answer, reverse the four coping questions and add all ten scores. Each question asks about the last month, with answers from 0 to 4: Never (0), Almost never (1), Sometimes (2), Fairly often (3), Very often (4).

Six questions are about feeling stressed. They ask how often you’ve been upset by something unexpected, felt unable to control the important things in your life, felt nervous and stressed, found you couldn’t cope with everything you had to do, been angered by things outside your control, and felt difficulties were piling up too high to overcome.

Four questions are about coping well. They ask how often you’ve felt confident about handling your personal problems, felt things were going your way, been able to handle the things that irritate you, and felt on top of things. For these four, the scoring is reversed, because answering “very often” is a good sign:

Then all ten scores are added up, for a total from 0 to 40. Higher means life has felt more stressful. If you score a paper version yourself, the reversed questions are where mistakes usually happen: forgetting to flip them can move a total by many points.

Why doesn’t the Perceived Stress Scale have official cut-offs?

Because it was built to compare levels of stress, not to sort people into groups. Cohen and colleagues designed it as a measure on a continuous scale, for research on how stress relates to health. They never published a line above which someone counts as “highly stressed”, and the scale isn’t a test for any condition.

That matters, because many websites show PSS bands of 0 to 13 as low stress, 14 to 26 as moderate and 27 to 40 as high. Those bands are simply the range cut into thirds. They didn’t come from Cohen’s papers, and they don’t compare you with anyone. Sprout uses the same thirds, but names them by what the answers describe rather than as low or high.

These descriptions are a rough guide to where your score sits in the range, not norms. A 26 and a 27 are almost the same experience, even though they land in different rows.

What do the PSS-10 result descriptions mean?

Sprout’s three descriptions range from feeling able to cope to feeling that difficulties are piling up. They describe your answers for the last month, rather than assigning a clinical level of stress.

0 to 13: mostly manageable

Life has mostly felt manageable. You seem to have felt able to handle what came up, even if there were some bumps along the way. It’s worth noticing what’s helping you feel on top of things, such as sleep, people you can talk to or a workload that fits, so you can lean on it when life gets busier.

14 to 26: some pressure

You’ve had a fair amount of pressure. Some things may have felt unpredictable or harder to keep on top of, alongside times when you felt more in control. This is a very common place to be. Looking at what’s piling up, asking for help with some of it and making room for rest can take the edge off. Retaking it next month shows whether things are easing.

27 to 40: a lot of pressure

Life seems to have felt stressful and hard to control much of the time. You may have felt things piling up faster than you could deal with them. That’s tiring, and it’s not a sign that you’re doing anything wrong. It may help to talk it through with someone you trust and look for anything you can put down for now.

What is an average Perceived Stress Scale score?

In the 1988 study by Cohen and Williamson, the average PSS-10 score in a sample of more than 2,000 American adults was about 13, with women scoring a little higher on average than men. That’s the figure most often quoted as a reference point.

That reference comes from one country, decades ago; later studies in other places and years have found different averages. Averages also vary with age, work and life circumstances. Knowing that the 1988 average was about 13 can be interesting, but it doesn’t tell you whether your own 18 is a problem. Your own score three months ago is a more useful comparison.

What does a high stress score actually tell you?

A high PSS-10 score tells you that, over the last month, life has often felt out of your control and more than you could handle. It doesn’t tell you why, how much is really going on, or whether you have a mental health condition.

The scale has some clear limits:

• It isn’t a count of events. Two people with the same busy month can score 10 and 30. The scale measures the felt side, which is often what matters most for health and mood.
• Stress, anxiety or low mood? The scale doesn’t separate them. Feeling nervous, irritable and unable to cope can come from any of them. If you’d like to see stress, anxiety and low mood side by side, the three DASS-21 scales show how a questionnaire measures all three. The post on telling stress from anxiety covers the difference in plain words.
• The source of stress. It doesn’t say where the stress comes from. Work, caring for someone, money, health and relationships all show up the same way in the score.
• It isn’t a diagnosis. There’s no condition called “high perceived stress”. The score points to whether it’s worth doing something about the pressure, and whether talking to someone might help.

Is a high stress score the same as burnout?

Not quite. Stress is the feeling of too much pressure, usually tied to what’s happening now. Burnout is what can follow when that pressure, mostly from work, goes on for a long time: an exhaustion that rest doesn’t fix, along with feeling detached or cynical about work and less effective at it.

The two often go together, and a high PSS score over several months can be an early warning. But someone can score high on stress during one hard month and recover fully when it ends, which isn’t burnout.

If work has drained you for a long time, the burnout test looks at how worn out you feel in general, from your work, and from the people you look after. The post on early burnout signs describes what to watch for, and recovering from long-term burnout covers what helps once it has set in.

Why might your PSS-10 score change?

Changes in demands, sleep, support and your sense of control can move your PSS-10 score. Because the questions cover the last month, each result describes a particular period.

• A demanding month. Exams, a deadline, a move, an illness in the family or a break-up can lift the score for a while.
• Sleep. A run of poor nights makes everything feel harder to cope with, and several questions pick that up. If your sleep has been suffering, the seven PSQI components offer a fuller sleep check.
• Support. Having someone to share the load with often lowers how out of control things feel, even when the load stays the same.
• Sense of control. Small changes that give you more say over your time, such as saying no to one thing or asking for a deadline to move, can lower the score more than you’d expect.
• How you answer. Answer for the month as a whole, not for today. A bad morning can tempt you to rate everything “very often”.

What should you do with your stress score?

Record your score with the date, then look for pressure you can reduce, share or postpone. Whatever the number, use it to choose a practical next step:

• Write it down with the date. Add a line about what’s been going on. Next month, you’ll have something real to compare against.
• Look at what’s piling up. Make a list, then ask which items you could drop, delay, share or do less well. Stress eases when the load does, not only when you cope better.
• Protect the basics. Sleep, regular meals and some movement are the first things to go under pressure and the quickest to make things feel worse.
• Give your body a break. Slow breathing calms the body’s stress response, and the guided breathing practice takes a few minutes.
• Talk to someone. A friend, a manager or a counsellor. Saying it out loud often makes the load clearer.

When stress is worth taking to a doctor

If stress is affecting your sleep, your health or your mood, a doctor or counsellor can help you find ways to ease it. That’s especially true if a score in the upper third has lasted more than a month or two, if you’re relying on alcohol or anything else to get through the day, or if you’ve felt low, hopeless or unable to enjoy anything for a couple of weeks. If you ever feel unsafe, contact your local emergency number straight away.

How often should you retake the Perceived Stress Scale?

About once a month, because the questions ask about the last month. Since there are no official cut-offs, your own results over time are the most telling thing the scale gives you.

A run of monthly scores shows patterns that a single one can’t: stress that rises every year before a busy season, a slow climb during a period of caring for someone, or a drop after a change at work. A score that keeps climbing is a sign to act before it turns into exhaustion.
