- Qi
- Item Score (points (0-4)) — Response to each item: 0=Never, 1=Almost never, 2=Sometimes, 3=Fairly often, 4=Very often
- SL
- Stress Level (category) — Low (0-13), Moderate (14-26), or High (27-40) perceived stress

Esempi risolti
Errori comuni da evitare
- ✕Forgetting to reverse-score items 4, 5, 7, and 8 which are positively worded (feeling confident, on top of things)
- ✕Using PSS scores for diagnostic purposes — the PSS measures subjective stress perception, not psychiatric diagnosis
- ✕Not recognizing that PSS scores are heavily influenced by current circumstances and should be interpreted in context

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.
