Unhealthy eating in children is a global problem, associated with poor long-term health outcomes
and evidence indicates that unhealthy eating habits developed early in life may track into adulthood.
Increasingly, description of behaviour change intervention development is encouraged. This paper describes the development and refinement of an online intervention designed to improve family eating behaviours.
Part 1 describes three pilot studies designed to collect quantitative and qualitative feedback about the
intervention to inform its development. This is followed by Part 2, which describes an additional study
covering other formative work involved in developing the intervention, including theoretical approaches,
evidence-base review and stakeholder input. The resulting, robustly refined intervention is described, the efficacy of which is being evaluated by a randomised controlled trial
