The aim of this multi-site study is to evaluate the effectiveness of mHealth intervention strategies for improving anti-epileptic drug adherence in caregivers of young children with epilepsy. A 2-month baseline period will be followed by two stages. In Stage 1 (3-months), caregivers will received either 1) a mHealth education module and automated digital reminders or 2) the mHealth education module, automated digital reminders, and individualized adherence feedback based. In Stage 2 (2-months), caregivers will either receive 1) continued individualized adherence feedback or 2) individualized adherence feedback and a mHealth problem-solving module. The primary outcome is electronically-monitored adherence. Secondary outcomes include seizure severity/frequency, quality of life and healthcare utilization.
