Summary

Portion size measurement aids (PSMAs) are tools that facilitate the estimation of food servings. The objectives of this study are to determine (a) if food portion size estimation accuracy differs when using a two dimensional (2D) PSMA (actual-size photos called Portion Size Cards) compared to a 3D PSMA (Portion Size Kit) and (b) whether differences exist in the short-term usefulness of and satisfaction with these PSMAs in a sample of parents of overweight children and youth. We hypothesize that the group that receives the 3D PSMAs will be more accurate in food portion size estimation and will be more satisfied with the tool compared to the group that receives the 2D PSMAs.

Interventions

BEHAVIORAL

Portion Size Measurement Aids (PSMAs)

Subjects are randomly assigned to receive either 2D or 3D PSMAs to examine accuracy, acceptability and usefulness of the models. Both groups receive brief instructions on the use of the respective PSMAs, complete an accuracy estimation task, and are given the 2D or 3D PSMAs to take home with them to use for 2-4 weeks, after which the researchers telephone parents to complete a brief satisfaction and usefulness survey.
