Dear all, Mobiile Media and Communication is issuing a call for papers for: *mHealth Use and Interventions: * *How Far Have We Come, and Where Are We Heading? * Guest editors are Constanze Rossmann, Holley Wilkin, and Komathi Ale, Along with the increasing penetration of mobile media and smart devices, the use of mobile media for health information and services (mHealth) has gained considerable relevance, both in developed and developing countries. A decade of developments, interventions, and evaluations has not only guided the design and application of mHealth, but also points towards future directions in mobile media research. mHealth can be applied to several areas, such as health promotion and disease prevention, disease monitoring and self-monitoring, diagnostic and treatment support, communication and training between healthcare workers, and disease and epidemic outbreak tracking. mHealth apps and interventions embrace a wide range of technological features, ranging from mobile telecommunication and text messaging and the use of features such as cameras, GPS, and accelerometers to multimedia applications, games, and connections to other devices such as glucometers, pedometers, and smartwatches. The potentials and limitations of mHealth are evolving as studies increasingly disseminate evidence of use and impact globally. For instance, mhealth offers the opportunity to reach certain target groups easily, to contact them repeatedly, to address people individually and at relatively low costs, and to offer interactive and tailored health communication. On the other hand, in spite of the growing ubiquity of mobile media technologies, certain groups remain disadvantaged in access to basic healthcare (e.g., hard-to-reach, resource-poor populations). Further problems arise around the value of mHealth apps, data security, actual adoption, and a general lack of attention to nuances in mHealth deployments. Despite the fact that there has been considerable research in this area, many questions continue to remain unsolved. Bringing these problems and gaps to light will lead us into the next decade of relevant and quality mHealth research. This calls for theoretically sound, methodologically deliberate and sustainable evidence for scalability, informed by realities of both the developed and developing regions. Essentially, this special section on mHealth use and interventions puts forth the question: How far have we come, and where are we heading?
