• 1 other identifier: NUS-IRB-2023-800
• Study Type: interventional

Brief Summary

The aim of the Move@NUS pilot study is to determine the feasibility of establishing a digital intervention cohort to monitor and improve the health and wellbeing of students by encouraging them to engage in healthy movement behaviours (i.e., physical activity, sleep, and limiting smartphone-based recreational screentime). The digital intervention cohort consists of:

• 6-months of continuous monitoring of movement behaviours, wellbeing and related factors via an Apple Watch and repeated bursts of ecological momentary assessments (EMAs).
• 3x embedded randomised controlled trials (RCTs) evaluating the efficacy of small-scale smartphone-based interventions designed to nudge participants toward participating in healthier movement behaviours.

Conditions

Physical Inactivity; Sedentary Behavior; Sleep Insufficiency; Well-Being, Psychological

Outcome Measures

Primary Outcomes (6)

• RCT 1. Sleep

  Sleep duration, as assessed via Apple Watch

  week 1 (pre-intervention), week 3 (intervention midpoint), week 5 (post-intervention), and continuously throughout the 6-month study

• RCT 2. Physical activity

  Step counts, as assessed via Apple Watch

  week 6 (pre-intervention), week 8 (intervention midpoint), week 10 (post-intervention), and continuously throughout the 6-month study

• RCT 2. Physical activity

  Flights of stairs climbed, as assessed via Apple Watch

  week 6 (pre-intervention), week 8 (intervention midpoint), week 10 (post-intervention), and continuously throughout the 6-month study

• RCT 2. Physical activity

  Moderate-to-vigorous physical activity, as assessed via Apple Watch

  week 6 (pre-intervention), week 8 (intervention midpoint), week 10 (post-intervention), and continuously throughout the 6-month study

• RCT 3. Screentime

  Screenshots of passively captured smartphone screentime data

  week 6 (pre-intervention), week 8 (intervention midpoint), week 10 (post-intervention), and continuously throughout the 6-month study

• Wellbeing

  Mental wellbeing, WHO-5 Well-Being Index (WHO-5; World Health Organisation). Min value 0, max value 100; higher scores indicate greater wellbeing.

  Continuously over 6-months
