StandUPTV Habits: Feasibility Trial for Maintaining Reductions in Sedentary Screen Time

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.
