Hospital Anxiety and Depression Scale

The Hospital Anxiety and Depression Scale or HADS is a questionnaire used to screen medically ill patients for anxiety and depression. It consists of 14 questions, seven for anxiety and 7 for depression. It does not contain all the necessary questions to make a firm diagnosis of anxiety or depression.

ME/CFS
The Hospital Anxiety and Depression Scale has been validated in many different patient populations, including cancer patients, but has not been validated for use in patients with ME/CFS.

HADS in research
HADS is sometimes used in research studies to approximate levels is anxiety or depression in patients who are physically ill. It has been heavily used by British paediatrician Esther Crawley.
