Summary

Our goal in this study is to further refine StandUPTV, an application designed to reduce SST in adults in our first study (ASU IRB # STUDY00012109), for the StandUPTV Habits program. This program aims to establish a non-sedentary habit triggered by an alert from the StandUPTV application after participants engage in approximately 30 minutes of SST in the evening.

Detailed description

This mobile health (mHealth) pilot study aims to develop and test an intervention designed to maintain reductions in evening sedentary screen time (eSST) over a 12-month period. The study will target a nationally recruited sample of adults at risk for type 2 diabetes and will employ a novel habit formation strategy to address individual barriers to sustained behavior change. As a Phase II pilot study within the ORBIT Model framework, this research seeks to provide critical insights into the relationship between maintained reductions in eSST and metabolic health. The intervention combines theory- and evidence-based approaches, leveraging commercially available screen time monitoring tools to scale the StandUPTV application. This pilot study will lay the groundwork for a subsequent Phase III fully-powered randomized clinical trial, aiming to evaluate the impact of sustained eSST reduction on diabetes and cardiovascular disease risk in a national sample.

Interventions

Type	Name	Description
BEHAVIORAL	Non-Sedentary Behavior Habit Formation	Action Plans Addition to the StandUPTV platform: The StandUPTV mHealth platform will be used to assess SST and deliver behavior change components. Participants will receive a technology kit including a Fitbit Charge 4+ and Wi-Fi-enabled smart plugs. The Fitbit and smart plugs will need to be used for the entire duration of the study participation. Participants will also be assisted with establishing an action plan for a non-sedentary break from evening sedentary screen time, which will be trigger by a StandUPTV alert delivered after performing 30 minutes of evening sedentary screen time.
BEHAVIORAL	Sedentary Screen Time Reduction Smartphone App	The StandUPTV application is used to monitor and reduce sedentary screen time (SST). The StandUPTV app has three components: LOCKOUT: Electronic lockout turns off screens when a predetermined limit is reached (50% of baseline value of weekly sedentary screen time). The app also includes planning tools and personalized strategies to limit SST. TEXT: Push notification prompts provide reminders, coaching, and personalized feedback (up to 2 per day). EARN: Opportunities to earn SST by engaging in MVPA, measured in 10-minute bouts.
