About

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.

Full 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.

48 participants in 2 patient groups

StandUPTV only

Experimental group

Description:

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.

Treatment:

Behavioral: Non-Sedentary Behavior Habit Formation

StandUPTV + Action Plans

Experimental group

Description:

Combining the StandUPTV application with personalized action plans to enhance the maintenance of reduced eSST. At baseline, participants will receive Action Planning Education, action planning worksheet, and weekly personalized text messages reinforcing the action plan. Participant will then receive a daily StandUPTV alert after performing 30 minutes of eSST, and they have 60 minutes after the alert to engage in their active chosen non-sedentary behavior. Financial Incentives: Participants can earn up to $30 per month during the 4-month intervention by starting 10 minutes of their non-sedentary replacement behavior within 60 minutes of the alert. Participants start with $30 in their account and lose $2 for each day they do not perform the behavior. Notifications will be sent via SMS and the StandUPTV app.

Behavioral: Non-Sedentary Behavior Habit Formation
