Hamilton Depression Rating Scale (HAM-D)

Hamilton Depression Rating Scale (HAM-D)


How to Use

The Hamilton Depression Rating Scale (HAM-D) has proven useful for many years as a way of determining a patient’s level of depression before, during, and after treatment.  It should be administered by a clinician experienced in working with psychiatric patients.


How to Score

Although the HAM-D form lists 21 items, the scoring is based on the first 17. It generally takes 15-20 minutes to complete the interview and score the results. Eight items are scored on a 5-point scale, ranging from 0 = not present to 4 = severe. Nine are scored from 0-2.

Sensitivity:  86.4%
Specificity:  92.2%
