This commentary aims to create initial recommendations to guide researchers' decisions on the development and use of mobile technologies for public health research. We recommend that mobile technologies for public health research should be scalable and sustainable; draw on social, psychological and/or behavioral theoretical models; be able to be integrated with multiple communication devices; incorporate social network and/or geographic metrics and take a community-based participatory approach to development and implementation. All of these approaches are discussed.Keywords: Guidelines, Health research, mHealth, New technologies, Use standards Development of mobile technologies and online social networking sites (e.g. Facebook) has created opportunities for researchers to use these technologies in public health research. [1][2][3][4] Scientific, health and engineering standards should inform decision-makers on how and when researchers use mobile technologies for health research and practice, yet few of these guidelines exist. 5 This commentary aims to create initial recommendations to guide researchers' decisions on development and use of mobile technologies for public health research.
Scalable and sustainableResearchers wanting to integrate mobile technologies into public health efforts have numerous technology choices. As capital is limited, focus should be placed on identifying scalable and sustainable technologies. Scalable technologies are typically built on and utilize 'platforms,' such as websites, tablets or phone applications with reusable components. For example, if multiple functions are needed for a mobile health smartphone-based intervention (e.g. a social networking/communication and geo-spatial tracking technology), one can either create each of these components or search for pre-existing and publicly-available technology equivalents. 'Opensource' technologies are platforms that can enable developers to freely build upon each other's efforts, minimizing redundant application development. 6 However, many current mHealth applications do not allow data to be shared with other technologies. We recommend that public health researchers seek to adopt scalable platform technologies to save resources and development time, while increasing longevity and utility of the technology.It is equally important that researchers choose to use technologies that are sustainable, or will maintain user participation and engagement. Although mobile technologies often receive tremendous acclaim upon initial release, many fail to gain a sustainable user base and become obsolete. For example, choosing a technology because it is currently making news headlines and therefore thought to be popular is not an approach that facilitates sustainability. No current data exist on whether to and how to categorize a technology as sustainable, especially as the definition of sustainability in research studies might be different from how sustainability is defined in other settings. This is an important issue that needs to be addressed giv...
