NCT04766372

Brief Summary

A four-arm randomised pilot trial involving:

  • 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

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (8)

  • Aerobic capacity

    week 0, week 12, week 24

  • Upper body strength

    week 0, week 12, week 24

  • Strength/ Power

    week 0, week 12, week 24

  • Change in Physical Activity Motivation

    week 0, week 12, week 24

  • Change in Body Appreciation

    week 0, week 12, week 24

  • +3 more secondary outcomes

Other Outcomes (1)

  • Process Evaluation

Study Arms (4)

Menu of physical activity options

EXPERIMENTAL

Participants in all 4 groups will receive this 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. Participants are asked to do 3 exercise 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 we will provide. .

Other: Behaviour change

Physical activity programme

EXPERIMENTAL

Participants in the second group with receive the activity menu (as described above) as well as a detailed physical activity programme. This programme includes supportive weekly text messages, access to live workouts and access to an online social community.

Other: Behaviour change

Individual behaviour change support

EXPERIMENTAL

Participants in the third group with receive the activity menu (as described above) as well as individual behaviour change support. Each participant is partnered with a trainee sport psychology ("Activity Mentor") who they have weekly video calls with to support their health behaviour change.

Other: Behaviour change

Activity Programme & Behaviour Change Support

EXPERIMENTAL

Participants in the fourth group will receive all of the above (exercise menu, live workouts, social community, support texts and weekly calls with an Activity Mentor).

Other: Behaviour change

Interventions

Using needs supportive, self-determination theory-based, components to improve the physical activity behaviours of adolescent girls.

Masking Details
Due to the nature of the study, it will not be possible to blind participants to their study condition (as they will know whether they are engaging the physical activity programme or not). As the researchers will be doing the data collection and conducting the behaviour change support calls, it will also not be possible to blind the researcher to the study.
