About the DASS-21
The DASS-21 (Depression, Anxiety and Stress Scale) is a short questionnaire used to reflect on current mood states over the past week. It looks at three areas – depression, anxiety and stress.
Each subscale is scored by adding its items and multiplying by two. The bands below are a general guide clinicians use:
| Subscale | Normal | Mild | Moderate | Severe | Extremely severe |
|---|---|---|---|---|---|
| Depression | 0–9 | 10–13 | 14–20 | 21–27 | 28+ |
| Anxiety | 0–7 | 8–9 | 10–14 | 15–19 | 20+ |
| Stress | 0–14 | 15–18 | 19–25 | 26–33 | 34+ |
The DASS was developed by Lovibond & Lovibond (1995) and is freely available for non-commercial use.
