Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The magnitude of this issue and how best to address it can be understood from a socioecological perspective. Researchers suggest developing multi-faceted and multi-tiered approaches that have scope for targeting the individual, interpersonal, organizational, and societal levels. The current research will test the first coach-led body image program for girls in sport. The Body Confident Athletes program was co-created with girls and coaches through an international multi-disciplinary partnership between academics, health professionals, industry, and community organizations. Multi-disciplinary partnerships can create a supportive landscape by upskilling girls and influential community members (e.g., coaches) in dealing with body image concerns, which will likely lead to sustained sports participation and biopsychosocial benefits.
As such, the aim of the present study is to conduct a large-scale randomized controlled trial (RCT) to evaluate the effectiveness of the Body Confident Athletes program. The program consists of three 60-minute sessions delivered by coaches to adolescent girls. Each session tackles a distinct theme related to body image in the sport context. Outcomes will be assessed at pre-intervention, post-intervention (three weeks later), and follow-up (at one and three months). Outcomes will include body image and sport enjoyment (primary outcomes); body appreciation, attuned self-care, resisting objectification, and positive and negative affect (secondary outcomes); and intervention acceptability, fidelity, and adherence (process outcomes). The comparison control arm will be a waitlist control condition.
To undertake this project, sports organizations will be cluster-randomized into the intervention group or the control group, with 800 girls anticipated in each arm. Those in the intervention condition will complete baseline assessments (target outcomes and demographic information), take part in the three-week intervention, and then complete the post-intervention and follow-up assessments (target and process outcomes). Those in the waitlist control condition will complete the baseline assessments (target outcomes and demographic information), a second assessment three weeks later (target outcomes only), and follow-up assessments after one and three months, after which they will get access to the intervention. However, their engagement with the intervention will not be monitored or assessed. At completion of the post-intervention survey, all participants will receive a debrief form, outlining the study aims and objectives, and support resources for body image and eating concerns.
The investigators hypothesize that girls who take part in the Body Confident Athletes intervention will report higher levels of body esteem, sport enjoyment, body appreciation, attuned self-care, resisting objectification, and positive affect and lower levels of negative affect at post-intervention and follow-up, compared to girls who do not take part in the intervention.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Body Confident Athletes
Participants in the intervention condition will take part in an in-person program consisting of three sessions over three weeks.
Body Confident Athletes
The Body Confident Athletes program is a three-session in-person program designed to be delivered by coaches to their athletes. Groups should be of approximately 10-20 girls. The sports organizations will work with the community partner and researchers on how to schedule the intervention over a three-week period. These sessions can replace a regular sport practice each week or an additional session can be organized by the sports organization. Each session will take approximately 60 minutes and will consist of four phases, including The Game Plan (5 mins), The Knowledge (20 mins), The Skills (20 mins), and The Final Score (15 mins). A variety of activity modalities will be utilized to convey learning outcomes, including group and individual activities and discussion-, writing-, and movement-based activities.
Waitlist control
Participants will not be explicitly told their study condition, although they will be made aware of the assessment time points and whether they will receive access to the intervention after the first survey (intervention group) or after follow-up assessments (waitlist control group). Following completion of follow-up assessments, the control condition will get access to the intervention, but they will not be monitored or assessed.
