HAM-A: Hamilton Anxiety Rating Scale
Fourteen-item clinician-rated scale covering psychic and somatic anxiety. Each item is scored 0 (not present) to 4 (very severe). Widely used as an outcome measure in anxiety trials.
Interpreting the total
| 0–7 | No or minimal anxiety |
| 8–14 | Mild |
| 15–23 | Moderate |
| 24–56 | Severe |
Notes
- Severity bands follow Matza et al. (2010). A commonly quoted older convention is 17 or less mild, 18–24 mild to moderate, and 25–30 moderate to severe.
- Psychic anxiety = items 1–6 and 14; somatic anxiety = items 7–13.
