Abstract

AIM:

The aim of this article is to compare 90-day and 30-day recall of Pediatric Migraine Disability Assessment (PedMIDAS) elements and headache frequency against daily entries from an Internet headache diary among pediatric patients and their parents.

METHODS:

In a prospective cohort study, patients aged 10-18 years with episodic migraine or probable migraine completed a 90-day Internet-based headache diary that incorporated PedMIDAS questions. Following the 90-day diary period, patients and parents completed modified PedMIDAS instruments to assess 90-day and 30-day recall. Intraclass correlation coefficients (ICC) were calculated to measure recall reliability. The Kruskal-Wallis and Jonckheere-Terpstra tests were used to explore recall accuracy as it relates to each participant's self-reported confidence in recall and to patient age.

RESULTS:

Fifty-two subjects completed 90 consecutive diary entries. Comparing 30-day to 90-day recall of PedMIDAS elements, ICC scores improved by 26.2% (patients) and 17.5% (parents). Patients had better recall than their parents for all study measures. Self-reported confidence in recall and patient age had limited and inconsistent effects on recall accuracy.

CONCLUSION:

The optimal recall interval to assess migraine disability must balance recall accuracy with generalizability across a range of headache frequencies. When compared to daily diary entries, recall accuracy of PedMIDAS elements and headache frequency improves at 30 days compared to 90 days. Parent report of migraine disability should not be used as a replacement for patient report.
