Feasibility of a Developmentally-tailored Mobile App for Tracking Mood and Pain in Children With Migraine

The Happyr App is a mobile app to support children and young people with primary headaches in tracking their mood and symptoms. The app was developed in close collaboration with patients, their parents, and clinicians (pediatric neurologists, pediatric pain psychologists). In the 'Happyr Tracking' study, we recruit 15 CYP aged 10-16 from the neurology department at Leeds Teaching Hospitals NHS Trust. Participants experience at least three primary headache attacks per month. After receiving information on the study via the Principal Investigator (PI), those interested can contact the research team to receive access to the Happyr App. In the app, participants and their parents/legal caregivers review information on the study and give their assent/consent. A copy of their signed assent/consent document will be sent to them as well as the research team and sponsor via email. After creating their account, participants receive a survey in the app. As soon as completed, they can access the app's features. Participants are asked to make an entry to their mood diary at least once per day and to their pain diary only on days they experienced a pain attack. Participants are asked to send a PDF of their pain diary data (which they can export in the app) to the PI at the end of the intervention period (8 weeks). After 8 weeks of using the app, participants will automatically receive another survey in the app to complete their participation. The pain diary export can be discussed with their clinician at their next appointment. Outcomes of the study will be analyzed from the two in-app survey at beginning and end of the intervention period as well as usage data from the app analytics. The study objective is to understand the acceptability and feasibility of the Happyr App.
