Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
TransformUs is a school-based intervention targeting reducing sedentary behaviour and increasing physical activity that will be rolled out across Australian secondary schools.
Overall duration of the intervention is 6 months i.e., the follow-up evaluation will be at 6 months for both the Effectiveness Trial and Implementation Trial. The effectiveness and implementation trials will run parallel to one another. Schools can only be involved in one trial, not both. Frequency and duration of each strategy will vary between the schools, teachers and students. Each of these components will include a repertoire of activities that teachers could choose and implement differently across the day. However, we are expecting that:
- Active breaks are short (up to 2-minutes) activities that interrupt prolonged periods (e.g., 20-30 minutes) of sitting in class. They can be incorporated into any class lesson. At least one active break should be planned for and delivered in each core lesson. For example: Active bingo, active grammar, chair yoga).
- Active lessons are longer sessions (e.g., 30 minutes) directly linked to the curriculum and involve integrating movement into the student learning experience. For example: times table teams (Maths), relay story (English).
- Active recreation (active play and recreation activities, before school, during school [recess and lunch included], after school) will depend on the length of each school breaks. Organised or non-organised activities frequency and length will also depend on the students likes, for example: Organised lunchtime Sports/activities could include Activity incursion: circus skills; Cross year level: Sports/activities (e.g. Basketball, Soccer, Netball); Year level activity: Activity (e.g. Ultimate frisbee, Dodge ball, Finska).
- Changes in the school environment (i.e., active indoor/outdoor environment, active equipment, teacher encouragement [champion], active school policies). For example: Borrowing system for active equipment at lunchtime; standing desks; use of sport uniform during whole week.
Teachers will be encouraged to implement the strategies as much as possible into their lessons. They also will be asked to encourage students to participate in the activities outside the classroom. The teacher will participate in a teacher development session (online or face to face, lasting for 30 minutes to 1 hour in duration). All the program resources, including a downloadable version of the teacher training, will be available through the TransformUs website. We will provide continuous communication and support from the TransformUs Team and a ‘champion teacher’ within the school to encourage engagement with the TransformUs resources.
For both the Effectiveness and Implementation Trials, the monitoring of the strategies will be including Ecological Momentary Assessment (during the intervention period) and the teacher survey. Both trials will also utilise interviews (at the end of the intervention – i.e., after 6 months).

Comparator / control treatment
It is not feasible to have a true control group from another state/territory as the program will be accessible nationwide on our website, and therefore we will use a waitlist control. The recruitment of the effectiveness trial schools will be staggered, i.e., as every 2 schools are recruited, they will be randomly assigned (using a computer-generated randomisation tool) to either receive the intervention (physical activity strategies) or to be put on a 6-month waitlist. The waitlisted schools will act as the comparator. Waitlisted schools will receive full access to the intervention and program after the final data collection has occurred (6 months after registration).

Eligibility
Key inclusion criteria
IMPLEMENTATION TRIAL
•As this is a real-world trial, all Australian secondary schools and school staff are eligible to register.
•TransformUs will be available to all secondary school staff in Australia, however, the research component will only be offered to secondary staff at Government and Independent schools (*). In 2020 there were 113,084 secondary school staff at Government and Independent schools across the country (ABS, 2020). Based on uptake of the TransformUs Primary program (ACTRN12617000204347), it is likely that no more than 5% of eligible staff will participate, which equates to approx. n=5654 staff. Only teachers registered to TransformUs who work in Government/Independent schools will be invited to take part in the research (surveys, EMAs and interviews). Based on response rates from TransformUs Primary, this is likely to be no more than 40% of registrants.

*Note: ethical approval will be sought from each State/Territory’s equivalent of the Victorian Department of Education and Training for the research component.

EFFECTIVENESS TRIAL
•Schools: Victorian and Tasmanian Government and Independent secondary schools (urban or rural), as well as Catholic secondary schools in the Archdiocese of Melbourne or Archdiocese of Hobart (as these are the two largest dioceses in each state). We aim to recruit a diverse range of schools from urban and regional areas, SES, type (Government, Independent, Catholic) and size. (n=Up to 10 schools).
•School staff (leaders): 1 nominated school leader per school (n=10)
•Year 7-10 teaching school staff at the Effectiveness trial schools will be invited to test the effectiveness of the program. *may be targeted depending on which teachers are delivering the intervention e.g. if maths is selected maths teachers (n=80)
•All year 7-10 students from Effectiveness trial schools will be invited to participate in the evaluation of the intervention (n=600)
Minimum age
11 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
IMPLEMENTATION TRIAL
•Any registrant working at a Catholic school will not be invited to take part in the research component (surveys, EMA’s or interviews). This is an operational decision as it would require applications to conduct research in these schools to approx. 25 separate dioceses across the country.
EFFECTIVENESS TRIAL
•Teachers who only teach years 11 or 12 and students in year 11 and 12 will not be recruited into the Effectiveness Trial. This is due to the timing of follow-up assessments coinciding with when end-of-year exams are likely to take place.

Efficacy
Statistical methods / analysis
Descriptive statistics will be used to describe the sample and percentage of participants who provided valid data for each time point. Linear mixed models will be used ((where the unit of the analysis (students) will be nested within cluster (class)) to examine the intervention effects of different level of implementation on key outcomes variables among adolescents. Separate models will be evaluated for each assessment point (i.e. at 6 months for the effectiveness trial and the implementation trial); adjusting for baseline levels of the outcome.

The level of implementation will be assessed using an implementation index. Data on aspects of implementation of each intervention component (i.e. active classroom, active recreation and school environment) will be scored, summed and collapsed into tertiles (low, middle and high implementation), using the implementation information that will be gathered from surveys and schools’ audit.

For the Environmental changes (SPACES data) an ICC and percent agreement will be calculated to assess reliability between virtual and physical audit tools. For the Adolescents’ activity levels in different areas (SOPLAY data): Data will be aggregated across scans. Differences in activity levels will be analyses using multilevel analyses to examine intervention effects.

All models will be adjusted for measured confounders age, gender, baseline values and accounted for clustering by school.
