Montgomery SA, Åsberg M.

"A new depression scale designed to be sensitive to change"

British Journal of Psychiatry 134 (4): 382–89.


I➜The Montgomery-Åsberg Depression Rating Scale (commonly abbreviated MADRS) is a psychological questionnaire used by clinicians to assess the severity of depression among patients who have a diagnosis of depression.
The MADRS depression test includes 10 items and uses a 0 to 6 severity scale. Higher scores indicate increasing depressive symptoms.
Validity: The MADRS was compared with the Hamilton Rating Scale for Depression on clinical assessments of severity of depression. The correlation for the MADRS was 0.71, slightly higher than for the Hamilton Rating Scale for Depression (0.65).
Reliability: The authors reported inter-rater reliability that ranged from 0.89 to 0.97 for various combinations of raters in small samples of 12 to 30 patients.
