คำถามที่พบบ่อย

What is a normal PSS-10 score?

The US population average PSS-10 score is approximately 13-16. Scores vary by age (younger adults score higher), gender (women average 1-2 points higher), and socioeconomic status.

How is perceived stress different from anxiety?

Perceived stress measures how overwhelmed you feel by life demands. Anxiety disorders involve persistent, excessive worry with specific diagnostic criteria. High PSS scores often co-occur with anxiety but are not equivalent — stress is situational, while anxiety may be dispositional.
