Researchers are conducting this quality-improvement MRT aiming to promote weight maintenance through increased activity and improved diet among people who received bariatric surgery. At the time it was developed, this project was novel in that it implemented separate randomizations at the start of the study, on a daily basis, and five times throughout the day.

This project tests the feasibility and effectiveness of providing, via a smartphone, just-in-time tailored physical activity suggestions as well as evening prompts to plan the following day’s physical activity so as to help sedentary individuals increase their activity. The resulting data will be used to inform the development of a JITAI for increasing physical activity.

This study seeks to examine the time-varying, contextual factors that influence daily oral chemotherapy adherence in adolescents and young adults with leukemia.

This study employs an MRT to test different strategies for promoting adherence to oral chemotherapy in adolescents and young adults with leukemia. It delivers individually-tailored content, including messages targeting disease self-management and preferred app engagement strategies.

The current study seeks to investigate whether, what type, and under what conditions prompts should be provided in the context of a weight-loss program that uses a mobile app as minimal support for obese/overweight adults.

JOOL is a behavioral health and well?being app that is designed to help people monitor and improve their sleep, presence, activity, creativity, and eating, with the ultimate goal of helping people move closer to fulfilling their life’s purpose. This MRT aims to understand whether push notifications of tailored health messages are useful in promoting engagement with the JOOL app; and, if so, when and under what circumstances they are most effective.

This project tests the feasibility of conducting an MRT aiming to investigate whether real-time sensor-based assessments of stress are useful in optimizing the provision of just-in-time prompts to support stress-management in chronic smokers attempting to quit. The resulting data will be used to inform the development of a JITAI for smoking cessation.

The smartphone addiction recovery coach (SARC) project tests the feasibility and effectiveness of providing, via smartphone, messages designed to encourage use of the ecological momentary interventions (EMIs) to support young adults enrolled in an outpatient substance-use program as they recover from disordered substance use.

The Substance Abuse Research Assistance (SARA) is an app for gathering data about substance use in high-risk populations. App developers are using an MRT to improve engagement with completion of the self-report data collection measures. At the time this summary was written, this MRT is unique in that it has an engagement component, but not a treatment one.
