Anxiety disorders
GAD-7
Extended assessment of generalized anxiety differentiated across 7 criteria. Used for clarification after HADS-A ≥8.
Coming soonThe Hospital Anxiety and Depression Scale (HADS) is a 14-item self-report questionnaire developed by Zigmond and Snaith in 1983 to detect anxiety and depression in patients in non-psychiatric hospital settings. Two subscales — anxiety (HADS-A) and depression (HADS-D) — are scored independently, each with 7 items.
A distinctive feature of the scale is that it deliberately excludes somatic symptoms (fatigue, sleep and appetite disturbance) that may stem from physical illness. This makes HADS suitable for assessing emotional state even in patients with significant physical comorbidity.
| Score range | Level | Clinical meaning |
|---|---|---|
| 0–7 | Normal | No clinically significant anxiety detected |
| 8–10 | Borderline | Subclinical symptoms; re-assessment recommended |
| 11–21 | Clinically significant | High likelihood of an anxiety disorder; extended assessment indicated |
| Score range | Level | Clinical meaning |
|---|---|---|
| 0–7 | Normal | No clinically significant depression detected |
| 8–10 | Borderline | Subclinical signs of depression; monitoring recommended |
| 11–21 | Clinically significant | High likelihood of a depressive disorder; comprehensive assessment required |
HADS is used for initial screening, monitoring the course of a condition, and assessing treatment response. Its brevity (2–5 minutes) makes it convenient for repeated administration.
A cut-off of 8 on either subscale is traditionally used as a signal for in-depth assessment. Sensitivity and specificity at this cut-off are around 0.8 for both subscales.
For longitudinal follow-up, a change of 2 points or more on a subscale is considered clinically meaningful (Deary et al., 2003). Smaller fluctuations usually fall within measurement error.
