Answer

In contrast to the above self-report scales, the Hamilton Depression Rating Scale (HDRS) is performed by a trained professional, not the patient. The HDRS has 17 or 21 items, scored from 0-2 or 0-4; a total score of 0-7 is considered normal, while scores of 20 or higher indicate moderately severe depression.
