Perceived Stress Scale
The Perceived Stress Scale is a specific operational definition utilized to quantify the abstract concept of stress. It serves as a self-report questionnaire where individuals provide scores that correspond to their level of perceived stress, thus transforming a theoretical variable into an observable and measurable format.
