Scoring/Interpretation: Higher scores indicate increasing depressive symptoms. Ratings can be added to form an overall score (range 0 to 50); no weights are used. Cut-off points include: 0 to 6 – symptom absent, 7 to 19 – mild depression, 30 to 34 – moderate, 35 to 60 – severe depression.

Quantitative/Qualitative: Quantitative

 

Validity (Quantitative): Concurrent validity determined by correlating scores to the Cornell Scale for Depression in Dementia (range r = 0.74-0.93, P < 0.0001). 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 (Quantitative):  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. Intraclass coefficients for this test fell between 0.66 and 0.82.
