Plain English summary of protocol
Background and study aims
The study aims to test whether the Tiny Tastes intervention is associated with increased liking for, and consumption of, the target vegetable after 14 daily tastings in a home setting, and to evaluate the acceptability of the mailed version of Tiny Tastes as a stand-alone intervention in a home setting.
Who can participate?
Participants are families with pre-school twins who are taking part in the Gemini study.
What does the study involve?
All families in the Gemini study will be sent a questionnaire which will include information about the Tiny Tastes intervention. Parents will have the opportunity to opt-in to the study by ticking a box at the end of the questionnaire booklet. Families who have responded positively to the invitation by March 2011 will be randomly allocated to either the intervention or the control group. Parents in both groups will be sent an information sheet, test instructions and a study plan. They will be asked to select a vegetable that both of their twins dislike and then to carry out three taste tests with each twin (two pre-tests and one post-test). The tests will each be completed 15 days apart. Parents will be sent clear instructions on how to conduct the tests and will receive a study diary to help them remember the study schedule. The outcome measures of the tests will be the childs intake (number of pieces) of the target vegetable and the childs liking (maternal rating) of the test food. The intervention group will also receive a sealed envelope containing an information letter and a Tiny Tastes pack, with instructions to open this after they have completed pre-test test 2. The Tiny Tastes pack will explain how to complete 15 days of tiny tastes with each twin, including information on the importance of repeated exposure, techniques of exposure feeding with repeated tiny tastes, the need for patience and persistence, and parenting techniques and suggestions for praise. Parents will also be directed to a website where they can view a video demonstrating the Tiny Tastes procedures. Participants in the control group will receive no additional intervention materials in the first instance. They will complete the three tests 15 days apart with no change to normal feeding habits in the intervening period. Control group families will be sent the Tiny Tastes materials and information following completion of the third test. The remaining families in the Gemini study will also be sent the Tiny Tastes materials to maintain consistency of treatment across the whole sample.
What are the possible benefits and risks of participating?
We do not expect any risks for participants completing this study.

| Scientific title | Tiny Tastes in Gemini - a postal intervention to increase vegetable acceptance in a cohort of pre-school twins: a randomised study |
| Study objectives | Compared with those in the no treatment control group, 3-5 year old twins in the intervention group will show increased liking for and consumption of a previously disliked vegetable after 14 daily tastings combined with rewards. |
| Ethics approval(s) | NHS Research Ethics Committee, 01/01/2008, ref: 07/H0714/116. Amendments accepted 26/01/2011 |
| Health condition(s) or problem(s) studied | Children's nutrition |
| Intervention | 1. All children will participate in two pre-intervention and one post-intervention assessments conducted in their home by their caregiver (following detailed instructions provided by the research team) 2. Families will be randomly assigned to one of two conditions: 2.1. Intervention condition: daily offer of target vegetable for 14 days with a sticker reward given for tasting 2.3. Control: no tasting between assessment sessions 3. All caregivers will be sent a follow-up questionnaire following the completion of the assessments |
| Intervention type | Other |
| Primary outcome measure | 1. Children's liking of their target vegetable (assessed by caregivers on a 9-point scale) 2. Consumption of the target vegetable in pieces 3. Both measures taken twice pre-intervention and once post-intervention |
| Secondary outcome measures | 1. Acceptability of Intervention measured by a follow-up questionnaire 2. Heritability of response to intervention |
