Pilot Study: The Effectiveness of a Mobile Application in Increasing Vegetable Acceptance

The parents filled in a questionnaire listing 25 vegetables and fruits and inquiring whether these had been offered to the child during the past 4 weeks and how the child reacted to those that had been served. All the listed vegetables and fruits were introduced in the app. The answer options were 0=was not offered during the past four weeks, 1=refused to touch food, 2=touched food but did not put in/near mouth, 3=put food to lips but not in mouth, 4=put food in mouth but spat out/did not eat, and 5=ate food. For each participant, we calculated an fruit and vegetable acceptance score by summing the answers to each of the 25 vegetable and fruit items, with higher scores indicating a higher fruit and vegetable acceptance (theoretical range 0-125).

Using the same questionnaire, we calculated the number of fruits and vegetables served during the past 4 weeks (range 0-25) and used this information to create a relative fruits and vegetable acceptance score (range 0-5) by dividing the fruits and vegetable acceptance score by the number of fruits and vegetables served.

The parents filled in a questionnaire describing the emotionality of the children using a Likert scale (1-5). The questionnaire covered four emotions. An average of two items per emotion were used to calculate the variables (scale 1-5).
