Clinical Trial Summary

A four-arm randomised pilot trial involving:

1. Physical activity programme only - live exercise sessions, social support, standardised text messages

2. Individual behaviour change support only - regular one-to-one video calls with an activity mentor

3. Combined - Physical activity provision and individual behaviour change support

4. Usual care control All groups will be provided with a menu of physical activities.

Objectives.

To conduct a RE-AIM evaluation of a 6-month multi-component PA intervention for adolescent girls, through investigating:

• Who the intervention reaches, how representative they are for the population (Reach, Adoption) and who is most likely to benefit from the intervention (Reach);

• The extent to which the intervention is delivered as intended (Implementation), and factors that affect this (Adoption);

• Preliminary impact on participants' PA, sedentary behaviour, cardiovascular fitness and psychological wellbeing at 3, 6 and 12 months (Effectiveness, Maintenance);

• The qualitatively examine the acceptability of the intervention for adolescent girls, and identify necessary refinements;

• To gather data to inform a sample size calculation for a main trail

Description:

Procedures. Following written informed assent of participants and consent of parents/guardians, the researcher will have a short introductory video call with the participant and parent to talk through the next steps, give instructions on how to complete fitness tests and answer any questions. After this introduction, participants can carry out their fitness testing at home remotely under the supervision of the researcher (via Zoom) or their parent. Following written consent, participants will complete all questionnaires online (approximately 15 minutes) - self-reported physical activity, sociodemographic and psychosocial measures (behavioural regulation in exercise questionnaire, body-appreciation scale and self-esteem scale - details of each listed below). Participants will then complete the fitness measures using the Resistance Training for Teens (RTFT) app (30 minutes) - 20m shuttle run tests, long jump and push up test. Participants will wear an Actigraph accelerometer on their don-dominant wrist continuously, as outlined in the study protocol, for 9 days before starting their 12-week physical activity programme. In total, assessments should take approximately one hour and will be conducted at baseline (week 0), post-intervention (week 12) and follow up (week 24).

Randomisation. Participants will be randomly allocated to one of the four intervention arms following baseline measures. 40 participants will be allocated to each arm using block randomisation on Microsoft Excel.

Intervention group - The goals of this physical activity intervention are to 1) increase adolescent girls total physical activity levels and 2) improve adolescent girls health behaviours, including body appreciation and motivation. This study hopes to build on our prior feasibility work to help us to understand which components of the intervention are most effective, i.e. a physical activity programme, individual behaviour change support or a combination. To achieve these goals the following elements will be implemented:

• Menu of physical activity options: Participants in all four groups will be given a booklet with suggestions of ways to be physically active, e.g. YouTube workouts, cycling or jogging, sports, or design their own using a home-based exercise booklet. They are asked to do 3 sessions of 30 minutes per week. Participants are asked to record what activity they did and the duration of the session using a method most convenient for them, e.g. notes on their phone, wall calendar or using an activity log template which the investigators will provide.

• Physical activity programme: Participants in groups 1 and 3 will receive -

• Non Reply SMS: Sent to the participant mobile three times per week by the primary researcher, Emma Cowley PhD candidate, from an online non-reply messaging service. This service is password protected. All messages will be standardised (not personally tailored) and will be focused on behaviour change techniques or reminders.

• Live exercise sessions: The researcher (with personal training and physical education teaching qualifications) will host two online group fitness classes each week which participants are also invited to join. This option is to allow participants the potential to engage with the other participants on the programme from the comfort of their own homes. It is also thought that having a scheduled set time to join a class on line may increase motivation and improve adherence, however the choice to join the class is optional. From previous feasibility work, these sessions were a highlight of the programme and often times parents and siblings would join in too. Participants are invited to turn their cameras on for the intro and warm up, however this is not mandatory.

• Access to a social media group: With participant and parental consent, participants are invited to join a private group community online where they can access additional resources provided by the research team, ask questions in an informal setting and communicate with the other participants in the programme. It is well researched that social connection is a facilitator to adolescent girls participation in physical activity and as participants will be exercising from home the investigators feel giving them access to a social, safe and virtual community can help give them this social connectedness to other adolescent girls of the same age. This is not compulsory and participants are free to join the group, leave the group or decline being added to the group without it affecting their participation in the rest of the programme.

• Individual behaviour change support:

• Participants in group 2 and 3 will be partnered with an 'activity mentor' whom they will work with for the duration of the intervention. These activity mentors are postgraduate students either studying for an MSc in sport and exercise psychology, or post-MSc and undertaking professional training. Their role is to support the participants with improving their health behaviours, autonomy and motivation. Participants will receive weekly calls from week 0-6 and then calls on week 9 and

12. Calls will be via phone call, FaceTime or Teams video call. Behaviour change support will be based on self-determination theory principles (autonomy, competence and relatedness; Ryan & Deci, 2000). Each call will be based on a pre-planned session outline and will be goal orientated, participant centred and focused on physical activity. Calls are expected to last 10-20 minutes per participant. A sub-sample of calls will be audio recorded to assess intervention fidelity.

Control: menu of physical activity options only. As this project runs for 6 months it will not be possible to provide the control group with the full physical activity programme (this is part of a PhD study). However, it is intended to provide the control group participants with intervention materials (home-HIIT booklets, field-based testing instructions) so that participants can implement the physical activity programme without the direct oversight of the research team. At the end of the intervention, control participants will also be offered to do a group behaviour change psychology session with an activity mentor.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Process Evaluation	Using a mixed methods approach, this study aims to conduct an evaluation of this physical activity intervention across five different domains (R-reach, E-effectiveness, A-adoption, I-implementation and M-maintenance).	week 0, week 12, week 24
Primary	Change in objective physical activity levels	Participants objective PA will be monitored continuously (i.e. 24 h/day) over a nine-day period using an accelerometer (actigraph GT9x software). This device will be worn on their non-dominant wrist and uses the same validated MEMS sensor as the Actigraph GT3X+ model which has been validated (Hanggi et al., 2013) and used extensively with adolescents (Corder et al., 2016). Using the Actigraph, total daily PA, moderate-to-vigorous PA and sedentary time can be assessed.	Baseline to post-intervention (week 12)
Secondary	Aerobic capacity	Measured by the 20m shuttle run test which has been validated as an effective instrument for adolescent aerobic capacity (Boreham et al., 1990). Participants will require 20m space e.g. garden or green space. Using the Resistance Training for Teens mobile app, participants will be given written and visual instructions of how to set up and perform the test. Participants are required to run back and forth between two markers (20m distance) on the sound of a beep. The audio can be played through the app.	week 0, week 12, week 24
Secondary	Upper body strength	Participants will do a push up test to the cadence of an audio recording. As above, written and visual instructions on how to set up and perform the test are provided on the app, as well as the audio file which sets the push up cadence. Should participants not be able to do a full push up (starting in high plank on hands and toes), they can lower onto their knees. It is important that the push up variation they choose is the same for baseline and post-intervention for fair comparison. No equipment is needed.	week 0, week 12, week 24
Secondary	Strength/ Power	Participants will do a long jump to assess their strength/power. They will start from one marker and just as far as they can and mark where they land. They will use a measuring tape to record this distance. If they do not have a measuring tape they can use their feet to measure and do this again for the post-intervention assessment for consistency. Again, the Resistance Training for Teens app provides visual and written instructions on set up and how to perform.	week 0, week 12, week 24
Secondary	Change in Physical Activity Motivation	measured by the 19-item Behavioural Regulation in Exercise Questionnaire (BREQ3) (Markland and Tobin, 2004) plus an additional five-items (Wilson et al., 2006). Using a 5 point Likert scale, the maximum score is 5 which indicates a high level of that particular sub-scale of motivation, e.g. intrinsic motivation rr amotivation.	week 0, week 12, week 24
Secondary	Change in Body Appreciation	measured by the 10-item Body Appreciation Scale (Avalos et al., 2005). Using a 5-point Likert scale, the maximum score is 5 which indicates a high level of body appreciation.	week 0, week 12, week 24
Secondary	Change in Physical Activity Competence	measured by the 4-item Perceived Competence Scale (Matsui & Muratas, 1997). Using a 7-point Likert scale, the maximum score is 7 which indicates a high level of competence towards physical activity.	week 0, week 12, week 24
Secondary	Change in Self-esteeem	measured by the 12-item Adolescent Self-Esteem Questionnaire (Hafekost et al., 2017). Using a 5-point Likert scale, the maximum score is 5 which indicates a high level of self-esteem	week 0, week 12, week 24
Secondary	Change in objective physical activity levels	Participants objective PA will be monitored continuously (i.e. 24 h/day) over a nine-day period using an accelerometer (actigraph GT9x software). This device will be worn on their non-dominant wrist and uses the same validated MEMS sensor as the Actigraph GT3X+ model which has been validated (Hanggi et al., 2013) and used extensively with adolescents (Corder et al., 2016). Using the Actigraph, total daily PA, moderate-to-vigorous PA and sedentary time can be assessed.	Baseline to follow-up (week 24)
