The GAD-7 asks how often seven common symptoms of anxiety — such as feeling nervous, worrying too much and being unable to relax — have bothered you over the last two weeks. Each answer scores from 0 (“Not at all”) to 3 (“Nearly every day”), so the total runs from 0 to 21.
It was first developed to look for generalised anxiety disorder, and it also picks up other common anxiety problems, such as panic disorder, social anxiety and post-traumatic stress. Doctors around the world use it, and it has been studied in Bangladesh too.
