Shining Star mHealth App for Preschoolers' Movement Guidelines
This study is testing a mobile app called "Shining Star mHealth App" to help preschool children (ages 3-4) meet recommended guidelines for physical activity, screen time, and sleep. The app is designed for parents to use at home over 12 weeks. Researchers want to see if the app can help children who currently meet 0 or 1 of these guidelines to meet all three. They also want to know if parents find the app easy to use. About 80 children are expected to join this study. The study is currently unclear on its recruitment status.
- Study design
- This is a randomized controlled trial comparing an intervention group using the app to a waitlist control group. It plans to enroll 80 participants.
- What's involved
- Participants will be randomly assigned to a group. If in the intervention group, you will use the Shining Star mobile app for 12 weeks. Physical activity, sleep, and screen time will be measured at the start, week 6, and week 12.
- Compensation
- Not stated in the trial record.
- Follow-up
- Measurements will be taken at baseline, week 6, and week 12, indicating a follow-up period of at least 12 weeks.

What this trial measures
- Physical Activity (ActiGraph GT3X+ accelerometer)Baseline, Week 6, and Week 12
Physical activity will be device-measured using an ActiGraph GT3X+ accelerometer. Participants will wear the accelerometer on their wrist with a Velcro band for 14 consecutive days after their baseline visit, Week 6 visit, and Week 12 visit, removing it only for water-based activities (e.g., bathing).
- Sleep (ActiGraph GT3X+ accelerometer)Baseline, Week 6, and Week 12
Sleep will be device-measured using an ActiGraph GT3X+ accelerometer. Participants will wear the accelerometer on their wrist with a Velcro band for 14 consecutive nights after their baseline visit, Week 6 visit, and Week 12 visit.
- Screen TimeBaseline, Week 6, and Week 12
Parents will report the average amount of time per day their child spent viewing screens (television, tablet, video game, cellphone, and other) while sitting or lying down, considering the past 30 days.
- Feasibility and Acceptability of the Mobile App (Weekly Surveys)Weekly
Participant's randomized to the intervention will receive weekly surveys within the app to evaluate the feasibility and acceptability of the mobile health application. Parents will report how easy or difficult it was to achieve specific goals using a Likert scale ranging from 1 to 5, where 1 indicates a poor outcome and 5 indicates a better outcome.
- Usability of the Mobile App (System Usability Scale)Week 6 and Week 12
Participants assigned to the intervention will rate their satisfaction with the app's design, appeal, and functionality using a 5-point Likert scale, which ranges from "Strongly Disagree" to "Strongly Agree." They will also complete the System Usability Scale (SUS), which also employs this 5-point Likert scale, at Week 6 and Week 12.
