The Migraine Disability Assessment Score (MIDAS)

 

Questionnaire - 5 items

 

(A) number of days in the last 3 months with any headache (If a headache lasted more than one day, count each day.)

(B) average headache pain on a scale of 0 – 10

 

MIDAS score =

= (work days lost) + (work days reduced) + (chore days lost) + (chore days reduced) + (leisure days missed)

 

Interpretation:

• minimum score: 0

• maximum score: 180 or 270

• The mean score in patients with migraine is around 20, with a few patients having scores of 60 or more.

 

Performance:

• The accuracy of the score would be greater for a person who keeps a headache diary.

• In a study for the score the Cronbach alpha was 0.73-0.76 and the test-retest Pearson correlation was 0.80-0.83.
