Stress is a normal part of life, but chronic high levels of stress can negatively impact both mental and physical health. The Perceived Stress Scale (PSS) is a classic psychological tool designed to measure the degree to which situations in one's life are appraised as stressful. This calculator uses the questions from the PSS to help you get an idea of your current stress level. Answering these questions honestly can be a valuable first step in recognizing and managing your stress.
