Project Adapt: Optimizing Just-in-Time Adaptive Intervention to Improve Dietary Adherence in Behavioral Obesity Treatment: A Micro-randomized Trial
Project Adapt aims to promote adherence to dietary recommendations provided during lifestyle interventions focused on weight management. The research team has developed a smartphone-based “just-in-time” adaptive intervention that monitors risk for potential "lapses" from a program's dietary recommendations, uses machine learning to determine if risk for lapse is high, and provides in-the-moment suggestions to help a person prevent lapse when necessary. The finalized tool aims to personalize suggestions and prevent lapses during high-risk times by analyzing which intervention strategies are effective for different individuals.
The FUEL Program: Using Multimodal Real-Time Assessment to Phenotype Dietary Non-Adherence Behaviors that Contribute to Poor Outcomes in Behavioral Obesity Treatment
The FUEL Program uses digital health tools such as smartphones and wearable sensors to understand different types of lapses from the recommended diet during lifestyle interventions for weight management. Dietary lapses may involve different sets of behaviors, such as overeating or consuming foods outside of someone's planned diet. This project seeks to identify which types of lapse behaviors are associated with different outcomes—such as weight change and caloric intake—to determine which kinds of lapses could have the most clinical impact (and therefore warrant intervention). The results will allow for the development of targeted interventions for the most impactful behaviors instead of trying to prevent any and all lapses from an eating plan.
The WATCH Study: Validating Sensor-based Approaches for Monitoring Eating Behavior and Energy Intake by Accounting for Real-World Factors that Impact Accuracy and Acceptability
The WATCH Study aims to improve measurement of caloric intake by investigating the potential of smartwatches and smart rings to detect eating gestures (“bites” of food or “sips” of drinks) during mealtimes. The researchers are evaluating whether bites and sips measured via a smartwatch or smart ring can be used to estimate how many calories a person consumes during a meal. The study aims to create a reliable method for estimating calorie intake during meals, a valuable tool for researchers and clinicians to monitor dietary behaviors in various contexts.

Self-E
Summary: Self-E is an app that helps individuals run randomized experiments on themselves to better understand their own behaviors that affect their health, well-being, and productivity.
Sochiatrist
Sochiatrist Social Data Extractor is an app that can help researchers understand how social messaging impacts mental health. The team is interested in understanding how private messaging (texts, direct messages, group chats) impacts a person’s emotional well-being and feeling of social support. The application can be used by researchers to collect anonymized messaging data for studies on mental health.

iENDURE: a combined web and text message-delivered intervention designed to support engagement in medication-based treatments for opioid use disorder.
Designing an initial test of whether iENDURE improves clinical outcomes of medication-based treatments for opioid use disorder. The pilot randomized clinical trial has concluded, and data analysis is currently in progress.
Project STAR (Supporting Transitions and Recovery)
This study aims to assess the effectiveness of a mobile peer recovery support app for individuals receiving medication-based treatment for opioid use disorder while incarcerated. The research will investigate whether using the mobile app after release from jail enhances social connectedness and support and if this leads to improved treatment engagement and a reduced likelihood of relapse into substance use. Data collection for this study is currently in progress.

Exploring Patient Acceptance: A Qualitative Study of a Digital Pill System for Medication Adherence Monitoring
Dr. Rosen conducts qualitative health research. Her current work includes investigating the acceptability of a digital pill system. Pills are labeled with an RFID tag that activates when swallowed and captures medication adherence. The data will allow clinicians to know when patients take their medications.

Equitable Pulse Oximetry
The COVID-19 pandemic exacerbated existing limitations in the healthcare delivery system and, in particular, highlighted longstanding health-related disparities. The rise of digital-health technologies (DHTs), ranging from advanced, wearable health-monitoring sensors to customized apps that facilitate novel health-intervention strategies, provides a unique opportunity to mitigate gaps in the delivery system and extend the reach of the healthcare system for both clinicians and clients alike. However, continued development and eventual implementation of DHTs must be done in a manner that incorporates input from a range of stakeholders with complementary areas of expertise, including but not limited to technologists, medical professionals, public health experts, health insurers, data scientists, and privacy experts. Equally important is to incorporate feedback from diverse communities for all stages of the DHT pipeline, especially from vulnerable populations that are subject to health disparities and adverse health outcomes. The mission of the Brown-Lifespan Center for Digital Health (CDH) is to facilitate the development, validation, and implementation of digital health technologies that advance health equitably. We aim to achieve this by:
(1) Establishing a framework for which digital health technology development and implementation can be carried out through the lens of diversity, equity, and inclusion and with input from Rhode Island stakeholder communities.
(2) Seeding collaborations between digital health researchers, technologists, medical professionals, and public health experts.
(3) Identifying pathways to clinical or commercial translation for the Brown-Lifespan digital health innovation community.
(4) Developing a clinically relevant platform for digital health innovators to simulate and test their technologies and strategies.
By achieving these goals and keeping to our mission, the CDH will realize its vision to advance the future of healthcare by bringing digital health technologies to everyone, anywhere
