The Perceived Stress Scale (PSS) is the most widely used psychological instrument for measuring the perception of stress. It is a measure of the degree to which situations in one’s life are appraised as stressful. Items were designed to assess how unpredictable, uncontrollable, and overloaded respondents find their lives to be. The scale also includes a number of direct queries about current levels of experienced stress. Moreover, the questions are of a general nature and hence are relatively free of content specific to any sub-population group. The questions in the PSS ask about feelings and thoughts during the last month. In each case, respondents are asked how often they felt a certain way.

From the PSS
"...a psychometrically sound global measure of perceived stress could provide valuable additional information about the relationship between stress and pathology.... the Perceived Stress Scale (PSS) [was] developed in response to these issues. The PSS measures the degree to which situations in one's life are appraised as stressful."
