What it measures
The PSS-10 measures perceived stress, meaning how stressful people find their lives rather than which stressful events happened. Its questions ask how often in the last month someone felt upset by something unexpected, unable to control important things, or that difficulties were piling up, and how often they felt confident and on top of things.
Who it’s for
It was designed for adults and is widely used with secondary and university students. Schools use it for staff wellbeing surveys, sixth form and exam-stress projects, and to evaluate interventions such as mindfulness programmes. It is not a diagnostic tool. For younger children, the Perceived Stress Scale for Children (PSS-C) is a better fit.
SAMPLE QUESTION
In the last month, how often have you felt that things were piling up too much?
Never · Almost never · Sometimes · Fairly often · Very often
Paraphrased example for illustration. The original wording is available from Cohen's lab at Carnegie Mellon.
How it’s scored
Each question is answered from 0 (never) to 4 (very often). The four positively worded questions are reverse scored, then all ten are added for a total from 0 to 40, where higher means more perceived stress. There are no official cut-offs. Informal bands are sometimes used (0 to 13 low, 14 to 26 moderate, 27 to 40 high), but the scale works best for comparing groups and tracking change.
Validation and source
Sheldon Cohen and colleagues published the original 14-item Perceived Stress Scale in 1983, and the 10-item version followed in 1988. It is one of the most cited psychological measures, with good reliability and links to health outcomes in many studies, and it has been translated into dozens of languages. Cohen's lab describes it as free to use for research and education. Requests to use it can be submitted free through the MAPI Research Trust; commercial use may need permission.
WHERE YOUHQ FITS
Validated scales measure. youHQ helps you act on what they show.
The PSS-10 gives you a monthly snapshot of how stressed people feel. Around exams and deadlines, stress can change week to week. youHQ gives pupils a quick daily check-in on how they're feeling, so staff can see pressure building and step in early. Use the PSS-10 to measure the bigger picture, and youHQ to know who needs support right now.
Frequently asked questions
Is the Perceived Stress Scale free to use?
Cohen's lab describes the PSS as free for research and education. Permission requests are free through the MAPI Research Trust, and commercial use may need specific permission.
What is a normal PSS-10 score?
There is no official normal range. Informal bands put 0 to 13 as low and 27 to 40 as high, but scores are best compared with similar groups or over time.
Can the PSS-10 be used with children?
It is designed for adults and older teenagers. For primary-age children, use a child-friendly version such as the Perceived Stress Scale for Children (PSS-C).
