The goal of this study was to assess the impact of MyMediHealth (MMH) \u2013 a website and a short messaging service (SMS)-based reminder system \u2013 on medication adherence and perceived self-efficacy in adolescents with asthma.<\/jats:p><jats:p>Methods We conducted a block-randomized controlled study in academic pediatric outpatient settings. There were 98 adolescents enrolled. Subjects who were randomized to use MMH were asked to create a medication schedule and receive SMS reminders at designated medication administration times for 3 weeks. Control subjects received action lists as a part of their usual care. Primary outcome measures included MMH usage patterns and self-reports of system usability, medication adherence, asthma control, self-efficacy, and quality of life.<\/jats:p><jats:p>Results Eighty-nine subjects completed the study, of whom 46 were randomized to the intervention arm. Compared to controls, we found improvements in self-reported medication adherence (P\u2009=\u2009.011), quality of life (P\u2009=\u2009.037), and self-efficacy (P\u2009=\u2009.016). Subjects reported high satisfaction with MMH; however, the level of system usage varied widely, with lower use among African American patients.<\/jats:p><jats:p>Conclusions MMH was associated with improved medication adherence, perceived quality of life, and self-efficacy.<\/jats:p><jats:p>Trial Registration This project was registered under http:\/\/clinicaltrials.gov\/ identifier
