The Montgomery-Asberg Depression Rating Scale (MADRS) is a ten-item diagnostic questionnaire which psychiatrists use to measure the severity of depressive episodes in patients with mood disorders. It was designed by British and Swedish researchers as an adjunct to the Hamilton Rating Scale for Depression (HAMD), which would be more sensitive to the changes brought on by antidepressants and other forms of treatment. There is, however, a high degree of statistical correlation between scores on the two measures.
The Montgomery-sberg Depression Rating Scale (MADRS) is administered by a trained interviewer, takes 20 minutes to complete and was designed as a measure of change in studies of the treatment of depression. It was developed by taking items from a longer scale. It is widely used in treatment trials, in both young and older patients. Specific instructions are given regarding the ratings and there is a comparative lack of emphasis on somatic symptoms, making it useful for the assessment of depression in people with physical illness. Cut-off scores have been suggested by Snaith:
- 0-6 indicates the absence of depression (or recovery in the setting of a clinical trial);
- 7-19, mild depression;
- 20-34, moderate depression; and
- 35 and above, severe depression.
