The Perceived Stress Scale (PSS-10) is a validated psychological questionnaire developed by Sheldon Cohen (1983) that measures the degree to which situations in life are appraised as stressful. It assesses perceived unpredictability, uncontrollability, and overload during the past month. It is the most widely used psychological instrument for measuring the perception of stress.
Tip: The PSS-10 is a screening tool, not a diagnostic instrument. It measures perception of stress, which may differ from objective stressors. High scores warrant discussion with a healthcare professional.
