What Are the Strengths and Limitations of the PSS?

One of the main strengths of the PSS is its simplicity and ease of use, making it accessible for large-scale epidemiological studies. It has been validated in various populations and languages, enhancing its applicability in diverse settings. However, the PSS also has some limitations. As a subjective measure, it relies on self-reporting, which can introduce bias and affect the accuracy of the data. Additionally, the PSS assesses stress over the past month, which may not capture long-term stress exposure.
