Mobile health (mHealth) interventions use mobile technology (tablets and smartphones) delivery platforms for interventions to improve health outcomes. Despite growing acceptance, there is little understanding of how consumers engage with and adhere to mHealth interventions. This study analyzes usage data from the intervention arm ( n = 42) of a randomized clinical trial testing the efficacy of the ezPARENT program and provides recommendations for using engagement and adherence metrics. Engagement was measured by parent usage (duration, frequency, and activity) of ezPARENT and adherence using an adherence index (the sum of individual modules completed, number of visits to ezPARENT, and maximum time between visits). Parents spent M = 37.15 min per module and had M = 13.55 program visits in the 3-month intervention period. Parents visited the program over a period of M = 69.5 days and completed 82% of the modules. These data provide support that parents will use intervention programs delivered digitally; engagement and adherence metrics are useful in evaluating program uptake.
