Description of intervention(s) / exposure
This study involves participants who undertake shiftwork for a Western Australian mining company. Participants are assigned to one of three intervention groups. Intervention group 1 will attend a 2-hour face to face group sleep education session; intervention group 2 will receive daily feedback on sleep via a wrist-activity monitor mobile app; and intervention group 3 will attend a 2-hour face to face group sleep education session and receive daily feedback on sleep via a wrist-activity monitor mobile app. The sleep education sessions will be delivered onsite by the researcher who has worked in the area of fatigue risk management for the past 7 years and holds a Post Graduate Diploma in Health and Safety, a Graduate Certificate in Public Health and a Bachelor of Science in Health Promotion.

Sleep Education Sessions - Interactive group sessions that include powerpoint presentation, videos, and discussion that address the following:
• What fatigue is and the importance of sleep in maintaining good health.
• The science of sleep, our biological clock and circadian rhythms.
• Common sleep disorders.
• Sleep deprivation and the dangers associated with micro-sleeps.
• How to recognise the signs of fatigue in yourself and others.
• Lifestyle and environmental factors that contribute to good quality and quantity sleep.
• Strategies to prepare for shift work.
• Strategies to manage fatigue and increase alertness during your shift.

Wrist-activity monitors - participants will wear a wrist-activity monitor 24 hrs a day (unless required to remove for safety reasons whilst at work) for the duration of 2 roster cycles (approx 42 days): pre-intervention, 21-days and post-intervention 21-day roster cycle.
The intervention group with access to the mobile app will receive daily info on their sleep quality, quantity and performance ie: sleep duration, sleep fragmentation, alertness levels. This intervention group will be required to sync their data daily with the mobile app allowing the researcher to monitor adherence to the intervention through a overall web app. The researcher will send text message reminders if participants aren't syncing their data.

Outcomes
Primary outcome [1] 322192 0
Sleep quantity. Measured by wrist-activity monitors.
Timepoint [1] 322192 0
The primary outcomes will be assessed for every day of the study (i.e. across multiple time points). The primary outcomes will be assessed across the pre-intervention phase (21-days) and across the post-intervention phase (21-days).
Primary outcome [2] 322270 0
Sleep Quality (as indicated by wake after sleep onset, fragmentation index, sleep efficiency and time in bed). Measured by wrist-activity monitors.
Timepoint [2] 322270 0
The primary outcomes will be assessed for every day of the study (i.e. across multiple time points). The primary outcomes will be assessed across the pre-intervention phase (21-days) and across the post-intervention phase (21-days).
Primary outcome [3] 322271 0
Cognitive performance. Cognitive performance will be predicted using scientifically validated biomathematical modelling. Biomathematical modelling allows for an objective assessment of fatigue by using scientific data to analyse the relationship between sleep, work and cognitive performance. The Sleep, Activity, Fatigue, and Task Effectiveness Model (SAFTE) model has been selected to conduct biomathematical modelling to predict cognitive performance for this research project
Timepoint [3] 322271 0
Biomathematical models will be run pre-intervention and post-intervention for each of the study groups using sleep data collected from the wrist-activity monitors as inputs (e.g. average sleep onset time, wake time and sleep duration).
Secondary outcome [1] 377653 0
Sleep Apnoea - A positive response to two or more of the categories in the Berlin Questionnaire indicates high risk for sleep apnoea.

Timepoint [4] 377934 0
The secondary outcomes will be assessed at the commencement of the pre-intervention data collection phase using the survey instrument.
Secondary outcome [5] 377935 0
Alcohol use. The Alcohol Use Disorders Identification Test (AUDIT). This survey was developed by the World Health Organization (WHO) as a simple method of screening for excessive drinking
Timepoint [5] 377935 0
The secondary outcomes will be assessed at the commencement of the pre-intervention data collection phase using the survey instrument.

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)
Participant identification (ID) numbers will be randomly assigned to a letter.
As each new person enters the study (i.e. meets the criteria and has signed the consent form) the next ID number and the predetermined group is assigned.
An independent person will assign the groups to A, B, C, D, to ensure the allocation is random. Allocation will involve contacting the holder of the allocation schedule who is “off-site”.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation will be used to randomly and evenly assigned to either the control group or one of the three intervention groups
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s

Sample size
Statistical power analysis was conducted using G*Power version 3.0.10 and indicated that a minimum total sample of 68 participants would be needed to detect a medium effect (Cohen’s f2=0.25) with 80% power and 1% level of significance (a) based on a repeated measures ANOVA design. The specified a is corrected to account for multiple outcomes, i.e. sleep onset latency, sleep duration, wake after sleep onset, fragmentation index and sleep efficiency.
Assuming an estimated 20% attrition, a total sample of 85 participants will be recruited for this study. This equates to 22 participants (rounded up) across each of the four study groups.

Statistical analysis
This study will test the effect of the independent variables, sleep education and the daily feedback on sleep via the mobile app on the dependent variables, sleep duration, sleep onset latency, wake after sleep onset, fragmentation index, sleep efficiency, sleep onset and time in bed.
Descriptive statistics in the form of mean, standard deviation and frequency will be used to summarise the data. A repeated measures ANOVA analysis will be utilised and the Group×Time interaction effect will be tested to assesses (pre-post) changes in (a) the dependent sleep variables within each of the study group, and whether these changes (if any) (b) are the same across all study groups. All analyses will be performed using SPSS v25. Due to multiple outcomes, Benjamini-Hochberg procedure will be used to correct the ensuing p-values to ensure Type I error is not unduly inflated. Significance is achieved if the corrected p<0.05 . Effect sizes, i.e. Cohen’s d and partial eta-squared will be presented where appropriate.

Summary
Brief summary
A multi-armed randomised control trial to assess the effectiveness of sleep education and wrist-activity monitors that provide daily feedback on sleep . These interventions were selected as they are frequently used by shiftwork organisations as part of a systematic approach to manage fatigue risk. However, the effectiveness of these interventions is somewhat unknown. An assessment of sleep quality, quantity, and cognitive performance will follow these interventions using both subjective and objective measures.
