Overview

Methodological study demonstrates the validity and reliability of the Turkish MTOQ-4 in adults with migraine, suggesting its utility for evaluating acute treatment effectiveness in primary care.

Key Points

  • To evaluate the validity and reliability of the Turkish adaptation of the Migraine Treatment Optimization Questionnaire-4 (MTOQ-4) for assessing acute migraine therapy outcomes.
  • Conducted a methodological study involving forward-backward translation, expert panel review, and pilot testing between May and November 2025.
  • Administered the Turkish MTOQ-4 face-to-face to adult migraine patients at a family medicine outpatient clinic.
  • Evaluated content validity (S-CVI/Ave), internal consistency (Cronbach's alpha), and construct validity (exploratory factor analysis with KMO and Bartlett's tests).
  • Achieved high content validity with a scale-level index (S-CVI/Ave) of 0.95 and strong internal consistency with a Cronbach's alpha of 0.829.
  • Demonstrated adequate sample structure and validity with a KMO value of 0.7887, significant Bartlett's test (p < 0.001), and all exploratory factor loadings exceeding 0.60.
