Description of intervention(s) / exposure
TransformUs All Abilities is a school-based intervention targeting reducing sedentary behaviour and increasing physical activity in children and adolescents with additional needs. The objective of this trial is to test the effectiveness of TransformUs All Abilities in relation to physical activity and sedentary time, on-task behaviour, socio-emotional skills, school attachment/sense of belonging, and engagement/enjoyment in students with disability.

The overall duration of the intervention is 6 months i.e., the follow-up evaluation will be at 6 months for the Effectiveness trial. The intervention will include a repertoire of activities that teachers could choose and implement differently across the day. Some examples of interventions are:
- Active breaks – 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 – 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 conducted before, during (including recess and lunch), and after school. The activity type, frequency and duration depend on the students likes and on the specific characteristics of each school’s environment and timetable. These may include activity incursion (e.g.,circus skills), sports (e.g., Basketball, Soccer, Netball) and other activities (e.g., Ultimate frisbee, Dodge ball, Finska).
- Changes in the school environment – active indoor/outdoor environment, active equipment, teacher encouragement (i.e., champion), active school policies. This may include, for example, a borrowing system for active equipment at lunchtime, the installation and use of standing desks in the classroom, and the 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 teachers and schools will have the option to participate in a teacher professional development session (online or face to face, lasting for 30 minutes to 1 hour in duration), at a suitable time up to a month prior to commencing the trial. All the program resources, including a downloadable version of the teacher training, will be available through the TransformUs website (www.transformus.com.au). 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.

Monitoring of the strategies will include Ecological Momentary Assessment (EMA) (during the intervention period). The EMA's are designed to assess frequency and duration of intervention, these will be sent via text message and take a few minutes to complete. The EMA's will be sent up to 3 times per term for up to 6 terms in total (depending on the commencement date of the trial). EMA's will be sent via text message.

Classroom observations on-task behaviour
Will be assessed by research staff observing students on the following behaviours: Focused on-task behaviour (e.g., reading, writing, asking/answering questions); Passive off-task (e.g., not focused, daydreaming, starring, drinking water); Off-task (e.g., not focused walking around, playing with irrelevant objects, fidgeting); Absent (e.g., went to the toilet). The different categories of off-task behaviour will be presented descriptively to provide contextual information on the type of behaviours students engaged in while off-task. A dichotomous variable (1=on-task, 0=off-task) will be used to test the intervention effects on on-task behaviour in the analysis.

Focus groups with students (18-30 students in total).
- Max n = 6 students per group, with varying levels of support requirements.
- A small group of students will participate in a 45-min focus group session (at the end of the trial) aimed at understanding how students with disability view opportunities for physical activity throughout the school day.
- Questions will relate to students' socio-emotional skills, school attachment/sense of belonging, and engagement/enjoyment .
- Focus groups will take place at the school in a room/space allocated to us by the school contact person (this component will only be possible if COVID-19 related restrictions will allow research staff to visit schools).

Eligibility
Key inclusion criteria
•Schools: Up to 6 special schools located in Victoria, up to 3 schools with students requiring a low to medium level of support, and up to 3 schools with students requiring a medium to high level of support. Categorising students by the level of support they receive will allow the research team to form homogenous groups by the level of support they receive rather than on diagnostic/clinical characteristics. This categorisation is intended to make the results of the trial in relation to the functioning variability easier to understand and more generalisable.
•School staff (leaders): 1 nominated school leader per school (n=6)
•School staff (teachers): Teachers and teacher aides delivering the program (approx. n=20)
•Students (physical activity, on-task behaviour, and life skills): Around 125 students in total with varying levels of support requirements
•Students (focus groups): 18-30 students in total (max n=6 students per group) with varying levels of support requirements.

Statistical methods / analysis
Quantitative data will be analysed using Stata 17 (Stata Corp. LLP). Preliminary analysis will be conducted to describe the sample (demographic characteristics and distribution of the scores on the outcomes of interest [total, by gender, by required level of support]). The assumption of normal distribution will be verified for all continuous variables and appropriate transformations will be applied to make the data normally distributed, if necessary.

The dataset will be stored in long format. Separate linear mixed models will be used to assess the fixed effects of the intervention (i.e., time [1 = baseline; 2 = end of trial]) on each continuous outcome (i.e., physical activity, social-emotional skills, engagement/enjoyment, and school attachment), adjusting for common confounders (i.e., age, sex, and student level of support) and controlling for the random effects of clustering (i.e., students in classrooms). The effects of an interaction term between time and student level of support will also be explored, to see whether different levels of support moderate the intervention effects.

On-task behaviour data (categorical) will be transformed into a dichotomous variable (i.e., 1 = on-task; 0 = off-task) by aggregating the two observable off-task behaviours (passive and disruptive) and removing observations in which a child was not in class (i.e., absent). Data will be stored in a long format to better suit the repeated measurements. Generalized linear mixed models will be used to assess the fixed effects of the intervention on the probability of observing students on-task using the variable time as explanatory (i.e., 1 = baseline; 2 = end of trial). The model will correct for the confounding effects of student’s gender, age, observed movement patterns and contextual factors (delivery mode and position in the classroom) and the random effects of clustering (i.e., multiple observation conducted with the same children who are nested in different classrooms).

Qualitative information collected from the focus groups will be transcribed verbatim and analysed using NVivo software; each quote will be coded and categorised in themes according to common implementation outcomes. Where coded quotes do not apply to any of the preconcerted themes, new themes will be created.

The power calculation for the main outcome of interest (physical activity) for the students participating in the Effectiveness trial is detailed below.
- The fixed effects were estimated with an a priori power calculation using G*Power software. Assuming a moderate effect size (f² = 0.15), an error probability = 0.05, and power (1 – ß error probability) = 0.80, the sample size that would been required to observe statistically significant differences using one predictor was 55 observations, using four predictors (i.e., correcting for three confounders) the required sample size would be 85 observations. Accounting for approximately 30% attrition, we will aim to recruit 125 students for this trial.

Potential confounders (i.e., age, sex, and level of support) will be adjusted in all the main analyses and will also corrected for the clustering at the class level (and the individual level for on-task behaviour).
