Objective

To develop a practical and valid questionnaire that assesses migraine knowledge for use in a future study measuring the efficacy of an educational intervention for patients.

Background

Many neurologists feel caring for migraine patients is too time consuming and migraine is a poorly understood condition among the lay public. First-time clinic visits are lengthy in large part due to the need for patient education. A validated migraine knowledge assessment tool may facilitate previsit education and assessment of migraine patients as a first step in shortening their visits.

Design/Methods We administered twenty multiple-choice questions anonymously online via Google Forms to 117 participants divided into two groups according to previous migraine training. We used Fisher’s exact test to determine the score differences between groups and group differences for each question. One sample proportion test identified answers chosen at random. We used random forest to identify those questions that best discriminated between the two groups. We used Receiving Operating characteristics (ROC) to validate the test.

Results Of the 117 subjects, 42 had migraine training and 75 had no migraine training. We removed five questions with no differentiation value and three questions considered ambiguous and subject to random answers. For the final 12-question test, there was a statistically significant difference in distribution of the total score between the two groups (score difference: 7.37, [95% CI 6.73-8.00], p<0.0001), with the higher scores found in the group with migraine training. ROC analysis determined an AUC of 0.996 with 95% CI (0.991,1), and internal validation resulted in a 100% sensitivity and specificity.

Conclusions The MigKAT-12© is a practical, valid, 12-item questionnaire that takes less than ten minutes to complete and successfully predicts migraine knowledge. Further research is warranted to validate its utility as an assessment tool for patient education.
