Effects of Experiential Learning on Vegetable Intake in Preschool Children

Status Completed

Clinical Trial Summary

The aim of this cluster randomized control trial is to test the efficacy of providing experience of a target novel vegetable within the context of an interactive story time to increase intake of the target novel vegetable in preschool aged children (aged 2-5 years).

Clinical Trial Description

The aim of this study is to test the efficacy of providing experience of a target novel vegetable within the context of an interactive story time to increase intake of the target novel vegetable in preschool aged children (aged 2-5 years). In particular, the study will assess whether these strategies are effective to encourage intake of an unfamiliar vegetable in children who are fussy eaters.

There are two manipulations in this study - the provision of a story which features either a target vegetable (celeriac) or a control vegetable (carrot) and the presence of experiential learning (smelling, touching, looking at the vegetable) with either the target vegetable or the control vegetable.

Baseline consumption and familiarity of the target veg will be assessed for all children, before the intervention. The intervention consists of two familiarization trials, and 2-weeks of access to a story book featuring vegetables. Following the final familiarization trial, consumption and familiarity will be assessed again. Each familiarization trial consists of a story in class, and depending on condition, an experiential learning episode in class. During the 2 week interval between familiarization sessions nurseries will be requested to ready the story book 5 times in the preschool room (at times convenient to them).

Participants will be cluster randomized into 4 groups (2X2 between subjects design): 1) target vegetable narrative, 2) target vegetable narrative + experiential, 3) control vegetable narrative 4) control vegetable narrative + experiential

Child's food fussiness data will be collected by parents using the Food Fussiness sub scale of the Child Eating Behaviour Questionnaire. Their usual consumption of the target vegetable will also be measured using parent report.

Nursery staff will be requested to provide feedback to evaluate intervention feasibility, barriers and efficacy.

It is predicted that children's intake of the novel vegetable will vary by intervention. The primary hypothesis to be tested is that providing experience of a target novel vegetable within the context of an interactive story time will encourage preschoolers to taste, try and eat the target vegetable. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
