Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* establishing a digital cohort study and continuously monitoring health behaviours and wellbeing (and related factors) for 6 months, and
* rapidly evaluating the effects of ecological momentary interventions (EMIs; small-scale interventions that provide support in real-time, delivered via the smartwatch and app) for promoting healthy movement behaviours via a series of embedded RCTs.
The investigators will enrol up to 150 first-year university students into an innovative hybrid study that combines a digital cohort with embedded randomised controlled trials (RCTs). The digital cohort consists of 6 months of continuous observations of movement behaviours, wellbeing, and related factors via a smartwatch (Apple Watch) and repeated bursts of smartphone-based ecological momentary assessment (EMA) surveys. Throughout the 6-month monitoring period, participants are enrolled in 3 embedded RCTs evaluating the effects of EMIs that, in turn, target sleep, physical activity, and smartphone-based recreational screentime. For each embedded-RCT we assess engagement and acceptability outcomes (e.g., whether a push notification is opened, whether it is responded to), and preliminary efficacy (i.e., whether there is a between group difference in the target behaviour from pre- to post-intervention). Participants also complete traditional questionnaires at baseline, 3-, and 6-month follow-up.
