Aims of the study

Feasibility study

• To assess the feasibility and acceptability of the FRESH recruitment strategy, intervention (including intervention fidelity), and accompanying outcome evaluation and;
• to explore how FRESH could be optimised through a mixed-methods process evaluation.

Pilot study

• To assess the feasibility and acceptability of the revised recruitment strategy, long-term retention, FRESH intervention and outcome evaluation (after feasibility testing) and;
• to explore further intervention optimisation and preliminary effectiveness.

Design

Feasibility study

A 6-week two-armed, parallel-group, randomised feasibility study, using a 1:1 allocation ratio, aiming to recruit 20 families with an index child aged 8-10 years. Following baseline assessment, families were randomly allocated to one of two intervention arms. In the child only arm, the index child was the focus of the intervention, with family members simply providing support. In contrast, in the family arm all participating family members received the FRESH intervention. Families in both arms received pedometers and access to the intervention website, enabling participants to select step challenges, log steps, and track progress as they virtually ‘walk’ around the world.

Pilot study

FRESH was an 8-week three-armed, parallel-group, randomised controlled pilot trial, using a 1:1:1 allocation ratio and long-term follow-up (52 weeks post-baseline). Following baseline assessment, families were randomly allocated to one of three arms: (1) FRESH arm, (2) pedometer-only arm, or (3) no-intervention control arm. All family members in the pedometer-only and FRESH arms received pedometers and generic family physical activity promotion information. FRESH families additionally received access to the intervention website, enabling participants to select step challenges, log steps, and track progress as they virtually globetrot. Control families were asked to carry on as normal.
