The McMaster Pediatric Migraine Questionnaire: a prospective validation study.

Objective: Migraine affects approximately 4%-11% of elementary school children; yet reaching a diagnosis in this age group can be challenging. The goal of this study was to develop a screening migraine questionnaire that could be easily implemented by a general pediatrician and validate its use in diagnosing migraine in children 5-12 years old.

Methods: A questionnaire, the McMaster Migraine Tool, was developed using the International Classification of Headache Disorders-II criteria for migraine. The validity of the questionnaire was assessed by comparing the diagnosis based on the results of the questionnaire compared with the diagnosis made by a pediatric neurologist.

Results: The questionnaire was used to assess a cohort of 69 children referred to the Pediatric Neurology Clinic for headache. The sensitivity and specificity of the McMaster Migraine Tool were determined to be 84% and 69%, respectively. Families graded its ease of use to be 9 of 10 (10 being easy to use).

Conclusion: The McMaster Migraine Tool may be useful in diagnosing migraine in 5-12-year-old children, as it is readily completed and regarded as easy to use. Application of this tool could lead to expedited diagnosis and management of migraine.
