Development of a text message-based headache diary in adolescents and children

Abstract

Background International guidelines recommend diaries in migraine trials for prospective collection of headache symptoms. Studies in other patient populations suggest higher adherence with electronic diaries instead of pen-and-paper. This study examines the feasibility of a text message-based (texting) diary for children and adolescents with headache. Methods This is a secondary analysis of data from a study validating a pediatric scale of treatment expectancy. We developed a Health Insurance Portability and Accountability Act-compliant texting diary collecting headache characteristics, medication use, and disability with 3–5 core daily questions for 4 or 12 weeks depending on headache treatment. Adherence was incentivized. Results 93 participants consented to the expectancy study. Five participants opted for a paper diary for follow-up. 88 participants chose the texting diary with 28 4-week and 60 12-week participants. Five participants did not complete the enrollment visit. Of those remaining 83, 89% of 4-week and 93% of 12-week participants responded on at least 80% of days. On average, participants fully completed 88% (4-week cohort) and 90% (12-week) of diary entries. Conclusions Text messages are a promising method for collecting patient-reported data. Adherence was similar to that reported for paper diaries in other pediatric migraine trials, but time-stamped entries ensure real-time data collection.
