Validity and reliability of the Turkish version of the mig-scog scale in migraine patients

Objectives: This study assesses the validity and reliability of the Turkish version of the Mig-SCog scale used to determine and monitor the cognitive functions of migraine patients during attacks. Methods: After completion of the translation process, for this validity and reliability study the Mig-SCog was administered to a total of 154 migraine patients (91 without aura, 32 with aura, and 31 chronic migraine patients) presenting to the Neurology Clinic of Istanbul Medipol University University. Internal consistency of the factors and the instrument as a whole were evaluated using Cronbach's alpha coefficient and an alpha value >0.60 was considered acceptable. Results: As in the original, the result of factor analysis found a good fit for a 4-factor structure of the Turkish version (KMO = 0.82 and Chi-square P = 0.409), and the factor structure was similar to the original. The factors of the instrument were evaluated as consistent (Cronbach's alpha >0.60), and an overall Cronbach's alpha of 0.8485 was calculated. Conclusions: The Mig-SCog showed sufficient validity and reliability to be used in Turkish society.
