Protocol - Migraine - Children
The Pediatric Migraine Disability Assessment (PedMIDAS) headache disability questionnaire is completed by the patient and his/her parent and is reviewed with the clinician or study staff. It captures the impact of headaches on school performance (three questions), activities at home (one question on homework or chores), and social and/or sports functions (two questions). The PedMIDAS is scored by summing the answers across the six questions. If a range is provided as an answer, either use the high end of the range or prompt for a single answer. The frequency and severity are not scored but can be used for clinical reference.
Pediatric Migraine Disability Assessment (PedMIDAS)
The following questions try to assess how much the headaches are affecting day-to-day activity. Your answers should be based on the last three months. There are no "right" or "wrong" answers so please put down your best guess.
1. How many full school days of school were missed in the last 3 months due to headaches?
2. How many partial days of school were missed in the last 3 months due to headaches (do not include full days counted in the first question)?
3. How many days in the last 3 months did you function at less than half your ability in school because of a headache (do not include days counted in the first two questions)?
4. How many days were you not able to do things at home (i.e., chores, homework, etc.) due to a headache?
5. How many days did you not participate in other activities due to headaches (i.e., play, go out, sports, etc.)?
6. How many days did you participate in these activities, but functioned at less than half your ability (do not include days counted in the 5th question)?
Total PedMIDAS Score
The PedMIDAS is scored by summing the answers across the 6 questions. If a range is provided as an answer, either use the high end of the range or prompt for a single answer. The frequency and severity are not scored but can be used for clinical reference.
