Perceived Stress Scale

What Is the Perceived Stress Scale?

The Perceived Stress Scale (PSS) is the most widely used psychological scale for measuring the perception of stress. Developed by Sheldon Cohen, Tom Kamarck, and Robin Mermelstein in 1983, it assesses how unpredictable, uncontrollable, and overloaded respondents find their lives during the past month.

The PSS-10 is a 10-item version that captures two core dimensions: perceived helplessness (inability to control or cope) and perceived self-efficacy (confidence in managing stress). It does not ask about specific stressors, instead it measures your subjective appraisal of stress across all life domains.

The PSS-10 is used in clinical research, employee wellness programs, health psychology studies, and population-level stress surveillance. It has been translated into over 30 languages and validated across diverse adult populations.

For each item, choose how often you felt or thought this way in the last month.

PSS-10 Score Interpretation

Population norms from Cohen et al. (1983) and replicated cross-cultural studies. Percentages are approximate and vary by sample.

Two Dimensions of Perceived Stress

The PSS-10 maps onto two underlying factors that predict different health outcomes:

Perceived Helplessness

Items 1, 2, 3, 6, 9, 10, feelings of uncontrollability, unpredictability, and being overwhelmed

Strongly predicts psychological distress, depression, and cardiovascular risk markers.

Perceived Self-Efficacy

Items 4, 5, 7, 8, confidence in handling problems, coping ability, and sense of control

Protective factor; higher self-efficacy buffers the helplessness dimension's health impact.

What High PSS Scores Predict
