The Hamilton depression rating scale (HDRS) is a widely used and validated instrument for assessing the severity of depression in clinical and research settings. It consists of 17 items, each rated on a scale of 0 to 4, with a total possible score ranging from 0 (no depression) to 52 (severe depression). The items cover a range of symptoms and behaviours related to depression, such as depressed mood, guilt, insomnia, and psychomotor agitation.
