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

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.

A Mobile App to Improve 24-Hour Movement Guideline Adherence in Preschoolers

The goal of this clinical trial is to evaluate whether a home-based mHealth intervention can improve adherence to the 24-Hour Movement Guidelines in preschool-aged children (3-4 years old) who currently meet 0 or 1 of the guidelines for physical activity, sedentary behavior, and sleep. The main questions it aims to answer are: * Can the intervention increase the proportion of children meeting all three 24-Hour Movement Guidelines (physical activity, screen-time, and sleep)? * Is the intervention feasible for parents to implement, as measured by a parent feedback survey? Researchers will compare an intervention group to a waitlist control group to assess whether the intervention leads to increased guideline adherence. Parents and Participants: * Children will wear an accelerometer to track physical activity and sleep patterns. * Parents will use a mobile app that delivers weekly lessons and behavior-related goals to encourage healthy movement behaviors in their children. * Parents will complete questionnaires on their child's movement behaviors and development at baseline, 6 weeks, and 12 weeks. * Additionally, children will undergo motor skills assessments, and parents will provide feedback on cognitive development and behavioral changes.
