Brief summary

We aim to assess the feasibility and acceptability of the BT80 recruitment strategy, intervention (including intervention fidelity), and accompanying outcome evaluation. In addition, we aim to explore how BT80 could be optimised through a mixed methods process evaluation. BT80 will be a 8-week single-arm feasibility study aiming to recruit 20 families from South-Western Sydney. The findings will provide insight into the feasibility and acceptability of BT80, which will be used to inform a future randomised controlled pilot trial.

Interventions

BT80 will be a 8-week single-arm family-based feasibility study. Approximately, 20 families will be recruited from Western Sydney and will be eligible to participate if at least one female child aged 7–11 years and at least one adult responsible for their care and living in their main household provide consent/assent. Participants must be able to partake in light-intensity physical activity (e.g., walking), have a sufficient understanding of the English language, and willing to commute to Wester

BT80 will be a 8-week single-arm family-based feasibility study. Approximately, 20 families will be recruited from Western Sydney and will be eligible to participate if at least one female child aged 7–11 years and at least one adult responsible for their care and living in their main household provide consent/assent. Participants must be able to partake in light-intensity physical activity (e.g., walking), have a sufficient understanding of the English language, and willing to commute to Western Sydney University – Campbelltown Campus weekly over the intervention period (tentatively March-May, 2024). No restrictions will be placed on family type (e.g., single parent, blended family). All other family members living in the index child’s main household will be invited to participate but their participation is not required. Each week, for 8 weeks, families will attend Western Sydney University – Campbelltown Campus and they will receive themed education sessions and interactive activities based on building healthy family routines and improving key risk factors affecting young people (i.e., physical activity, muscle-strengthening activity, diet, screen time/sedentary behaviour, sleep). Each week, participants will also participate in rugby league focused physical activity sessions. Sessions will be approximately 80-90 mins each week (split between the education and physical activity sessions). Each week there will be variation in the delivery of the educations sessions where some education and interactive activities will be delivered to parents only or children only, or whole families together. All sessions will be mainly delivered by the research team. Intervention adherence will be monitored through attendance checklists. All outcomes will be assessed twice, at baseline (prior to intervention delivery) and intervention end (i.e., 8-weeks post-baseline), except for the process evaluation outcomes which will only be measured once at intervention end.
