Hamilton Depression Rating Scale (HDRS)
Hamilton, M. (1960). A Rating Scale for Depression. J Neurol Neurosurg Psychiatry, 23: 56-62.
The variables are measured either on five-point or three-point scales, the latter being used where quantification of the variable is either difficult or impossible. No distinction is made between intensity and frequency of symptom, the rater having to give due weight to both of them in making his judgment.
0-4 scale: 0= absent, 1= mild or trivial, 2&3= moderate, 4= severe 0-2 scale: 0= absent, 1= slightly or doubtful, 2=clearly present
