Short Description of Instrument
The nine-item Mig-SCog covers two domains: executive functions and language. The Mig-SCog was developed to measure attack-related cognitive complaints in migraine attacks.
 
The assessment has good psychometric properties (internal consistency reliability and test–retest reliability). The Mig-SCog is is inexpensive and very simple to complete.
Scoring
The nine questions of the Mig-SCog have three possible answers that indicate the absence of the symptom, the symptom occurring sometimes during headache attacks, and/or symptoms occurring often during headache attacks.
 
Questions asked on the Mig-SCog correspond to the following domains:
 
  • Questions 1-3 – executive functioning (attention, processing speed and orientation)

  • Questions 4-5 – planning and attention

  • Questions 6-7 – language (comprehension and speech production)

  • Questions 8-9 – ability to name

The total Mig-SCog score is computed by adding up the scores of the nine scale items.
