Objectives: Meditation-based interventions (MBIs) hold promise for enhancing health and well-being. However, substantial barriers impede engagement in traditional forms of these interventions. Innovations in mobile health offer an avenue for overcoming barriers associated with traditional MBIs. This paper examines the potential of a particular mobile health innovation – Ecological Momentary Interventions (EMIs) – as a strategy to enhance the accessibility, acceptability, and efficacy of MBIs. Methods: We discuss the historical context, conceptual foundations, motivation for adoption, and empirical evidence supporting the potential of EMIs. Additionally, we explore the conceptual intersections between EMIs and both traditional contemplative sources and contemporary secular MBIs. Furthermore, we describe empirical studies integrating EMIs into MBIs (i.e., meditation-based [MB]-EMIs). Results: Studies have demonstrated diverse approaches to integrating EMIs into MBIs. These studies exhibit variability in key dimensions, including the MBI with which the EMI is integrated and the characteristics of the EMI itself. MB-EMIs have therapeutic potential, but there are many important scientific questions about them that have not yet been answered. Discussion: Future studies should continue to examine the impact and safety of meditation-based EMIs, leverage innovations in passive data collection, explore user experiences, develop these interventions for and with marginalized populations, and emphasize informal meditation practice.
