Human-centered design approach to building a transition readiness mHealth intervention for early adolescents.

Objective: Mobile health (mHealth) interventions may be an efficacious strategy for promoting health behaviors among pediatric populations, but their success at the implementation stage has proven challenging. The purpose of this article is to provide a blueprint for using human-centered design (HCD) methods to maximize the potential for implementation, by sharing the example of a youth-, family-, and clinician-engaged process of creating an mHealth intervention aimed at promoting healthcare transition readiness.

Method: Following HCD methods in partnership with three advisory councils, we conducted semistructured interviews with 13- to 15-year-old patients and their caregivers in two phases. In Phase 1, participants described challenges during the transition journey, and generated ideas regarding the format, content, and other qualities of the mHealth tool. For Phase 2, early adolescents and caregivers provided iterative feedback on two sequential intervention prototypes. Data were analyzed using thematic analysis in Phase 1 and the rapid assessment process for Phase 2.

Results: We interviewed 11 youth and 8 caregivers. The sample included adolescents with a range of chronic health conditions. In Phase 1, participants supported the idea of developing an autonomy-building tool, delivering transition readiness education via social media style videos. In Phase 2, participants responded positively to the successive prototypes and provided suggestions to make information accessible, relatable, and engaging.

Conclusions: The procedures shared in this article could inform other researchers' plans to apply HCD in collaboration with implementation partners to develop mHealth interventions. Our future directions include iteratively developing more videos to promote transition readiness and implementing the intervention in clinical care.
