Methods: A systematic review of existing literature was conducted to examine the primary functions, strengths, and limitations of mobile apps to increase the access of underserved populations, such as Chinese migrant workers, to information and services. Through categories and keyword searches, relevant apps on Apple’s App Store and Google Play were identified, analyzed and compared to the research literature. In particular, seven apps with different functions were selected and analyzed to assess their strengths and limitations.
Results: In Western countries, related apps, many of which were first designed for usage in medical purposes, serve one or more of the following functions: resource location, reference tools, and self-assessment and symptom management. The functions have different degrees of connection between individual users and service providers, ranging from passive, information only to active, dynamic interaction. A systematic survey of existing literature and apps has found the strengths of apps in facilitating social and behavioral health services to include accessibility, functionality, engagement, social networking, and privacy. Challenges include high cost of app development, user research, data security, ongoing maintenance, and difficulty in finding a specific app. A prototype of mobile apps for the delivery and provision of health and social services in the context of Chinese migrant workers is developed.
Conclusions and Implications: Results highlight the potential of apps to increase the access of difficult-to-reach population such as Chinese migrant workers to information and services in the social and behavioral health fields. However, service awareness by accessing to information should only be seen as an initial step, future studies should evaluate the effectiveness of various functions in service engagement, usage and outcomes within the population.
