The Appetite Toolbox is a programme developed for use in preschools and designed to promote children's appetite awareness and eating regulation skills through a series of books, classroom activities and mealtime routines developed with curriculum specialists and aligned to the Centre's core curriculum competencies (e.g. Language and Literacy, and Social and Emotional Development).~Using a Hybrid Type I cluster-controlled pilot design, the Appetite Toolbox for preschools study aims to:~i) Characterise the effectiveness of the Appetite Toolbox delivered over to increase children's awareness of appetite and eating regulation skills over a six-week period.~ii) Assess implementation of the Appetite Toolbox in preschool centers, with a focus on acceptability, appropriateness, fidelity, and feasibility of Appetite Toolbox as delivered by preschool educators.~The research team will also explore whether differences in home feeding practices and implementation factors moderated the effectiveness of the Appetite Toolbox in preschools.~Children will be recruited from N2, K1 and K2 classrooms across six preschools from the same anchor operator and three locations (18 classrooms in total, three per school). At each location, preschools will be randomised to complete the Appetite Toolbox programme over a period of six weeks, either immediately (intervention group) or later in the school year (waitlist-control group).~Effectiveness will be characterised by changes in children's ability to communicate meaningful changes in appetite, portion selections and tendency to snack in the absence of hunger. While implementation measures will assess the utility of training provisions alongside fidelity, acceptability, and appropriateness of the Appetite Toolbox programme in both the intervention and waitlist schools, captured through a series of questionnaires, in-class observations and interviews with teaching staff, central curriculum leaders and specialists.~The research results will provide important evidence for the impact and application of the Appetite Toolbox materials as a low-cost means to improve childhood eating behaviours via preschools and early years education, and inform the design of a larger-scale definitive trial.
This study uses a Hybrid research design to assess the effectiveness and implementation of a preschool-based programme - the Appetite Toolbox - delivered by Early Childhood Educators to promote children's appetite awareness and eating regulation skills. Children, their caregivers and classroom teachers will be recruited across 18 classrooms from preschool childcare centers. Preschool educators will deliver the Appetite Toolbox over a period of six weeks. Using a waitlist-control design we will measure changes in children's appetite awareness and eating regulation skills in school and describe implementation outcomes, such as fidelity, acceptability, and feasibility of the programme.
