Abstract

Background: The importance of assessing “food literacy” since youth has been highlightedand, to this purpose, valid and consistent instruments are needed. This study aimed to assess thevalidity and internal consistency of the preschool-FLAT (Food Literacy Assessment Tool). Methods.505 children from 21 kindergartens, recruited within the Training-to-Health Project in Palermo(Italy), underwent oral sessions and activities on food-related aspects. Their knowledge/skillswere recorded in the preschool-FLAT. The following scale measures were assessed: Contentvalidity; internal consistency (Chronbach’s alpha coefficients); construct validity (Structural EquationModeling—SEM); discriminant validity (intervention subgroup of 100 children vs. control groupof 27 children). Results. Acceptable content validity of a 16-items scale and overall adequateinternal consistency were revealed: Content validity index (CVI) 0.94, content validity ratio(CVR) 0.88, Chronbach’s alpha 0.76. The SEM revealed a 4-factor model fitting the data well(comparative fit index 0.939, root mean square error of approximation 0.033). Discriminant validitywas good (intervention group scoring higher than control, p < 0.001, unpaired Student’s t-test).Conclusion. The preschool-FLAT revealed good psychometric properties, adequate validity andinternal consistency. This is the only instrument in the literature specifically targeted to 3–6 years oldchildren that could be effectively used to assess food literacy.
