The mHealth Shared Resource (mHealth SR) developed the InsightTM mHealth Platform to offer incredible opportunities to design, evaluate, rapidly implement and disseminate studies. The InsightTM Platform enables researchers to create innovative mobile applications that: 1) identify proximal and distal antecedents to imminent health risk behaviors using self-report surveys (i.e., ecological momentary assessments [EMAs]), wearable sensors and geolocation data; and 2) conduct Just-in-Time Adaptive Interventions (JITAI) that tailor intervention content in real-time based upon location, survey responses, and sensor data. InsightTM is customizable for each research project, utilizes a web-based content management system (CMS) for easy access across multiple browsers, and uses architecture that enables the incorporation of new features. Users of this service log into a web-based CMS and follow step-by-step guidance to create and manage research studies, enroll and monitor study participants, create EMA items, create different types of EMAs (e.g., random, daily, participant-initiated, sensor-initiated) and create specific assessment rules (e.g., two vs. four random assessments per day). Once study parameters and content have been created in the CMS, researchers transfer their study materials into the smartphone application shell. The customized smartphone application can be made available on the Android app store, and will soon be available on the Apple app store. Data are encrypted within the smartphone application and automatically and securely uploaded into mHealth servers. Encrypted data can be downloaded from the server by users at any time. Given that 85% of Americans now own smartphones, smartphone-based interventions are highly scalable and disseminable.
