What is Perceived Stress Scale (PSS)

The Perceived Stress Scale (PSS) is a trusted tool for measuring the perception of stress. It helps clinicians understand how overloaded or unpredictable a client feels. Developed by Cohen, this questionnaire asks about feelings and thoughts during the last month. It focuses on general stress levels and current overload rather than specific events. The scale uses a simple format where respondents rate items from zero to four. Questions explore how often things seem uncontrollable. Some items are positively phrased to measure the ability to cope, so you will need to reverse score them for the final total. Taking only a few minutes to complete, the PSS is popular in research and clinical settings. It is great for tracking changes in stress over time. Since the questions are general, it works well across different groups and gives a clear snapshot of how someone is handling daily pressure.

PSS Scoring

The Perceived Stress Scale can be scored using a straightforward summation approach. For the common 10 item version, patients rate how often they felt stressed on a 0 to 4 scale. Before calculating the final number, you'll need to reverse scores for the four positive items asking about control and confidence. This means a 0 becomes a 4, and a 4 becomes a 0. Once that's sorted, simply sum all responses to get a total ranging from 0 to 40. Higher scores point to greater perceived stress, helping clinicians spot who might need extra mental health support.
