Take 17 items of this Hamilton depression scale, if the total score is less than 7 points is normal, the total score in the 7-17 points, may be depressed, the total score in the 17-24 points, then certainly have depression, the total score is greater than 24 points, often suggests that there is serious depression. Clinically, it is mostly used for the evaluation of depressive symptoms in depression, bipolar disorder, neurosis, and so on.
