Primary use / Purpose: 

The WillTry was designed to measure children’s willingness to try fruits and vegetables.


Childhood obesity has become a worldwide epidemic. The American Academy of Pediatrics’ recommendations for the assessment, treatment, and prevention of childhood obesity highlight the importance of encouraging children to eat the recommended servings of fruit and vegetables. However, this can be a difficult task and factors such as socioeconomic status, preference, parental intake, nutritional knowledge, self-efficacy, and shared family meals have been found to influence a child’s consumption of fruit and vegetables. The WillTry was designed to measure self-reported willingness to try fruits and vegetables (both novel and common) in children aged 5-14 years. The WillTry is interviewer administered and consists of 22 items. The child must indicate whether they would try, would maybe try, or wouldn’t try the fruit or vegetable mentioned in each item. A total scale score can be computed, along with subscale scores for the willingness to try fruit and the willingness to try vegetables. The instrument may be of use in developing interventions to increase children’s consumption of fruit and vegetable or weight loss interventions. 


The psychometric properties of the instrument were evaluated by Thomson and colleagues (2010).
