A hybrid digital intervention combining continuous monitoring with embedded RCTs is feasible for promoting healthy movement behaviors in university students.
This pilot study protocol describes a five-month hybrid design using Apple Watches and iPhones to monitor sleep, physical activity, and screen time in first-year university students, with three embedded RCTs testing ecological momentary interventions. Feasibility outcomes include recruitment, engagement, and user experience, with preliminary effectiveness explored for each movement behavior.

A hybrid digital intervention combining continuous monitoring with embedded RCTs is feasible for promoting healthy movement behaviors in university students. The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).
The Claim
A hybrid digital intervention combining continuous monitoring with embedded RCTs is feasible for promoting healthy movement behaviors in university students.
This conclusion is most relevant to: First-year undergraduates at the National University of Singapore, aged 18-25 years, who own or regularly use an iPhone and an Apple Watch..
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸MOVE@NUS digital intervention cohort: protocol of a pilot study to promote healthy movement in university students. (Journal of activity, sedentary and sleep behaviors, 2026) —
How It Works
The proposed biological pathway:
- ▸Continuous passive monitoring collects real-time movement data
- ▸Ecological momentary interventions delivered via study app based on data or self-reports
- ▸Participants receive standard health messages or personalized reminders
- ▸Result: Potential improvement in sleep, physical activity, or screen time behaviors
Who Might Benefit
Evidence fit by population:
- ▸First-year undergraduates at the National University of Singapore, aged 18-25 years, who own or regularly use an iPhone and an Apple Watch.
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Pilot study with small sample size limits generalizability
- ▸Preliminary effectiveness only explored, not confirmed
- ▸Reliance on Apple Watch and iPhone ownership may introduce selection bias
Frequently Asked Questions
What is the main goal of the MOVE@NUS study?▼
To assess the feasibility and preliminary effectiveness of a hybrid digital intervention combining continuous monitoring with embedded RCTs to promote healthy movement behaviors in university students.
How are participants randomized in this study?▼
For each of the three embedded RCTs (sleep, physical activity, screen time), participants are randomized on a 1:1:1 schedule to control, intervention 1, or intervention 2.
What types of ecological momentary interventions are used?▼
EMIs include standard health messages or personalized reminders based on HealthKit data or participants' self-reported behaviors and preferences, delivered via the study app.
How long does the study last and what are the measurement points?▼
The study lasts 5 months, with online questionnaires at baseline, midway (2.5 months), and endpoint (5 months), plus eight EMA bursts (three-day periods every two weeks).
