Study type
Interventional
Description of intervention(s) / exposure
The aim of this intervention is to evaluate the effectiveness of the Fitbit Flex (and accompanying app) combined with digital behaviour change resources to promote physical activity in inactive adolescents. The intervention is grounded in Social Cognitive Theory and Behaviour Choice Theory. Following the completion of baseline measures, schools will be randomised to either the intervention or wait-list control group. The 12-week intervention will include a Fitbit Flex and accompanying app, weekly individual and/or team missions to complete, and digital behaviour change resources accessed via social media (e.g. infographics, social forums, short videos etc.). Alerts to new ‘missions’ and content will be delivered via email or text message 2-3 times per week. Participants will be asked to wear the monitor as much as possible throughout the 12 weeks. Adolescents will access the resources and be encouraged to participate in 12 missions (delivered at the start of each week) in their own time. Examples of weekly missions include ‘Break it up’, where adolescents will be asked to identify share ideas on how to move more and sit less, ‘Buddy up’, where participants will try to identify and implement ways to help others (e.g. family) to be more active, and ‘Build it up’, where participants will be asked to think about changing one thing that could help them to be more active. The accompanying resources match the weekly themes (e.g. how to set SMARTER goals), will step participants through the behaviour change process and target behaviour change techniques in an interactive, flexible way. The focus of the intervention is the accumulation of physical activity across the day.

Adherence to the intervention will be monitored by documenting engagement with the intervention elements (e.g. numbers reporting engagement with resources, social media contributions etc.).

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will not be concealed. Schools are eligible to participate if they are located within a socioeconomically disadvantaged area of Melbourne. Voluntary, written informed organisational consent will be obtained for schools to participate. Participants (students and teachers) will then be recruited through schools. Year 8 students who meet the minimum age criteria will receive a recruitment pack containing Plain Language Statements and Consent Forms to take home to their parents, In order to participate, students will be required to return signed parental consent forms, which will also include student assent to participate, to their school for collection by the research team. Once baseline assessments have been completed, schools will be randomised into either the intervention or wait-list control group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The project will use a group randomised controlled trial design. Schools will be randomly allocated to intervention or wait-list control groups for the duration of the study.

Schools will be match-paired based on their size and then randomly allocated to either the intervention or control using a computer-based random number generator. Participants attending schools in the intervention group will receive the 12 week physical activity program. Participants attending schools in the wait-list control group will not receive the physical activity program during the study period. However, at the conclusion of the final assessments, participants will receive the information and resources.
