How stressed have you felt this month?

1)What is the Perceived Stress Scale?

The Perceived Stress Scale, or PSS, is a brief questionnaire that measures how unpredictable, uncontrollable, and overloaded you have found your life over the last month. It was developed by Sheldon Cohen and colleagues in 1983 and has since become one of the most widely used stress measures in psychology and health research around the world. The 10-item version, the PSS-10, is the one most people use today.

What sets it apart is the word perceived. It does not count the stressful events in your life; it asks how stressful they felt to you. Two people can face the same hard month and rate it very differently, and it is that felt sense, not the raw event count, that tends to track with how stress affects sleep, mood, and health. Because it is short and easy to repeat, you can take it again a few weeks later to see whether anything has shifted.

2)Signs and symptoms of stress

Stress is not only a feeling of pressure in your head; it shows up across the mind, body, and behaviour, which is part of why it can be so hard to place. The PSS focuses on the sense of being overwhelmed and out of control, but the full picture is broader.

• Mind: constant worry, racing thoughts, trouble concentrating, feeling overwhelmed, and a sense that things are piling up.
• Body: tension headaches, tight or aching muscles, a racing heart, stomach trouble, tiredness, and disrupted sleep.
• Behaviour: snapping at people, withdrawing, procrastinating, relying more on caffeine or alcohol, and letting habits slip.

Everyone experiences some of these at times; that is normal, and a certain amount of stress sharpens focus and helps you meet a deadline. What the test is really probing is how often, over the last month, you have felt stretched beyond what you can handle, because that persistent, uncontrollable feeling is what separates ordinary pressure from something worth a closer look.

3)How the scoring works

Each of the ten questions scores from 0 (never) to 4 (very often), so your total runs from 0 to 40. A higher total points to more perceived stress. Four of the questions are positively worded, asking how often things went your way or you felt on top of things, and these are reverse-scored, so a confident answer lowers your total rather than raising it. The commonly used bands are:

The reverse-scored items are there to catch not just how much strain you feel, but how much control and confidence you feel alongside it. Someone can be busy and pressed yet still feel on top of things, and the scale is built to tell those two states apart. A raised score is an invitation to look closer, not a verdict.

4)What your score means, and what it doesn't

A single score is a snapshot of the last month, not a label and not a diagnosis. Stress naturally rises and falls with sleep, workload, relationships, and life events, so the direction it moves over time matters far more than any one number. Two people can both score 20 and be in completely different places: one climbing into a hard stretch, the other coming out of one.

It is also worth being clear about what the test is and is not. Stress is not itself a mental-health disorder, and a high PSS score does not mean you have one. The scale measures perception, how in or out of control you have felt, rather than counting events or diagnosing anything. And because it looks back over a single month, a rough four weeks can push it up and a calm four weeks can flatter it. This is exactly why retaking it and watching the trend is more informative than fixating on a single result.

5)What to do next

• Low: simple daily habits, steady sleep, regular movement, paced breathing, and brief check-ins, often keep stress from building.
• Moderate: put the basics in place, protect your sleep and downtime, and consider trimming what you can from your load if it holds or climbs over the coming weeks.
• High: it is worth taking seriously. Alongside the basics, consider talking with a doctor or therapist, especially if stress is affecting your sleep, health, or daily life. A screen is a prompt to look after yourself, not a diagnosis.
• In every case, retake the test every couple of weeks. The trend line tells you far more than any single reading.

If you are struggling to cope, or you are having thoughts of harming yourself or feel in immediate danger, please contact local emergency services or a crisis line you trust right now. You do not have to manage this alone, and reaching out is a sign of strength, not weakness.

6)Why tracking stress over time helps

A test taken once tells you where you are today. A test taken regularly tells you where you are heading, and direction is what you can actually act on. Tracking your stress alongside everyday factors like sleep, exercise, and stressful events tends to surface patterns that are invisible from the inside, that your worst stretches follow short nights, say, or that things reliably lift after a couple of calm days. Those patterns are where change becomes possible, because they turn a vague sense of being stressed into specific, addressable causes. Andy is built around exactly this loop: a quick daily check-in, and a clear view of how your mood and stress move over the weeks.

7)About this test

The PSS is free to use for non-profit research and education, without a fee. This page follows the original 10-item scoring, including the four reverse-scored items, and is intended for screening and education only. It does not store your answers and is not a substitute for professional care or diagnosis.
