Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will access the intervention through the online survey platform (likely Qualtrics). The video will become accessible to intervention group participants immediately following completion of the baseline data collection (survey). The intervention video will be embedded into the platform. Participants will be randomly allocated to the intervention or control group using the platforms random allocation function.

The intervention will include an engaging multi-media explainer video designed for young adults. It will use a narrative approach, featuring a main character who represents our target population. Guided by a narrator (spoken by either one of the investigators or a computer-generated voiceover), the viewers are guided on an animated journey exploring some of the key dimensions of sleep health (e.g., regularity, alertness, timing, efficiency, duration), including norms and common challenges experiences by young adults. This content will be developed based on the National Sleep Foundations Sleep Duration and Quality Guidelines and recent relevant empirical research. There will also be information on basic sleep physiology. The intervention video will be approximately 10 minutes in duration.

Adherence of the intervention will be monitored through analytics from the online survey platform that displays how long participants stayed on the intervention video/page.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed as done centrally by computer (specifically the online survey platform).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created
by computer software (i.e. computerised sequence
generation) - Randomisation performed by survey platform (e.g. Qualtrics XM 'randomizer').
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
Intervention assignment
Parallel
Other design features
Phase

Type of endpoint/s
Efficacy
Statistical methods / analysis
An a priori calculation, with d = .30, a = .05, and power = .80 indicated minimum number of participants as n = 24 in each group. Accounting for ~20% attrition for follow-up, n = 29. Thus, ~29 participants per group, and 58 participants in total.

Descriptive statistics will be used to summarise demographic information and baseline characteristics of the participants. To evaluate the efficacy of the intervention, a generalized linear mixed model will be employed for categorical outcomes, while a repeated measures ANOVA will be used for continuous outcomes. The group x time interaction will be used to determine intervention efficacy. Significance level of all statistical analysis will be set at p < .05.
