Summary
The Migraine Therapy Assessment Questionnaire (MTAQ) reliably and validly identifies patients with suboptimal migraine management in primary care settings. This tool aids in assessing migraine control and treatment effectiveness.
Area of Science:
- Neurology
- Clinical Research
- Psychometrics
Background:
- Migraine management requires effective tools for assessing patient outcomes.
- The Migraine Therapy Assessment Questionnaire (MTAQ) was developed to evaluate migraine treatment effectiveness.
Purpose of the Study:
- To determine the reliability and validity of the Migraine Therapy Assessment Questionnaire (MTAQ).
Main Methods:
- Adult patients (18-65) with monthly migraines were recruited.
- Participants completed MTAQ, SF-36, MIDAS, Beck Depression Inventory, and other surveys.
- Test-retest reliability, construct, and predictive validity of MTAQ were assessed.
Main Results:
- MTAQ demonstrated high reliability with kappa statistics ≥0.5 and agreement ≥76%.
- MTAQ scores correlated significantly with SF-36 and MIDAS, indicating construct and predictive validity.
- Suboptimal migraine management was linked to specific MTAQ item responses.
Conclusions:
- The MTAQ is a reliable and valid instrument for identifying patients with suboptimal migraine management.
- It is suitable for use in primary care settings to guide treatment adjustments.
