Understanding the Hospital Anxiety and Depression Scale (HADS)
What Is the HADS?
The Hospital Anxiety and Depression Scale (HADS) is a brief, reliable, and valid self-report questionnaire developed by Zigmond and Snaith in 1983. It is specifically designed to identify states of anxiety and depression among patients in non-psychiatric hospital clinics. Unlike other mental health screening tools, HADS minimizes the influence of somatic symptoms that could be confounded with physical illness, making it especially suitable for patients with chronic or acute medical conditions.
Structure and Content of the HADS
The HADS consists of 14 items divided into two subscales:
- Anxiety (HADS-A): 7 items
- Depression (HADS-D): 7 items
Each item is scored on a 4-point Likert scale ranging from 0 to 3, leading to a maximum score of 21 for each subscale. The total scores help clinicians categorize the severity of anxiety and depression symptoms:
- 0-7: Normal
- 8-10: Borderline or mild
- 11-21: Moderate to severe anxiety/depression
This straightforward scoring system makes HADS an accessible tool for routine screening.

Implementing HADS in Clinical Practice
Preparing to Use the HADS
Before administering the scale:
- Explain the purpose to patients, emphasizing confidentiality.
- Ensure a quiet environment to facilitate honest responses.
- Clarify that there are no right or wrong answers, and they should answer based on their current feelings.
Administering the Scale
The HADS can be administered:
- In paper form, using the printed PDF.
- Digitally, by converting the PDF into a digital questionnaire.
- During routine check-ups or as part of a comprehensive assessment battery.
It usually takes about 2-5 minutes to complete, making it suitable for busy clinical settings.
Scoring and Interpretation
After collecting responses:
- Sum the scores for each subscale.
- Use the thresholds to determine if further assessment or intervention is needed.
- Keep in mind that HADS is a screening tool, not a diagnostic instrument; positive screens should be followed by comprehensive psychiatric evaluation.
