2.3.2. Perceived Stress Scale (PSS)

This scale is widely used to measure stress perception [27]; it aims to understand how participants perceive their lives as unpredictable, uncontrollable and overloaded, and includes questions about their levels of experienced stress. The 10 items of the PSS ask about feelings and thoughts over the past month; respondents are asked how often they feel in a particular way and all responses are on a five-point answer scale from "never" (0) to "very often" (4).
