Measure your perceived stress level with the PSS-10, the most widely used stress assessment tool. 10 questions about how you have felt over the past month.
This is a screening tool, not a diagnostic instrument. It does not replace professional evaluation. Your responses are not stored or transmitted — all processing happens locally in your browser.
The Perceived Stress Scale (PSS-10) was developed by Sheldon Cohen, Tom Kamarck, and Robin Mermelstein in 1983. It measures the degree to which life situations are appraised as stressful — how unpredictable, uncontrollable, and overloaded you find your life.
You will be asked 10 questions about your feelings and thoughts during the last month. For each, indicate how often you felt or thought a certain way.
This assessment takes approximately 3 minutes to complete.
Stress is the body's response to any demand or challenge. While acute stress can be beneficial (motivating performance and focus), chronic stress has significant negative effects on physical and mental health. The PSS-10 measures perceived stress — how stressful you appraise your life to be — rather than counting specific stressful events.
Research links chronic stress to cardiovascular disease, immune dysfunction, digestive problems, sleep disorders, anxiety, and depression. The good news is that stress is highly modifiable through evidence-based interventions including regular exercise, mindfulness meditation, cognitive-behavioural techniques, social support, and adequate sleep. Understanding your stress level is the first step toward effective management.

While stress and anxiety share similar symptoms (racing thoughts, tension, irritability), they have different causes. Stress is typically a response to an external trigger (work deadline, relationship conflict) and tends to resolve when the trigger is removed. Anxiety can persist without a clear external cause and involves excessive worry about future events. Chronic stress can lead to anxiety disorders if not managed effectively.
Evidence-based stress reduction strategies include regular physical exercise (at least 150 minutes per week), mindfulness meditation, adequate sleep (7-9 hours), social connection, time in nature, limiting caffeine and alcohol, setting healthy boundaries, and cognitive restructuring techniques. For persistent high stress, professional support through therapy (particularly CBT) has strong evidence for effectiveness.
