Squire's Quest: intervention changes occurred at lunch and snack meals.

This study identified fruit, 100% juice and vegetables (FJV) consumption changes by meal among fourth grade students participating in Squire's Quest!, a 10-session individually focused psychoeducational multimedia game with many meal/environment specific behavioral change techniques incorporated into the programming. Participants in 26 elementary schools were randomly assigned to treatment or control groups. Four days of dietary intake were assessed before and after the intervention to determine FJV servings consumed by meal. Overall, students receiving the intervention consumed 1.0 serving FJV more per day compared with control condition students. Using mixed model analysis of covariance, significant increases were found for servings of fruit and 100% fruit juice at snacks, and regular vegetables at lunch for intervention school children compared with children in control condition schools. These meals and snacks were targeted by the intervention activities and appear to represent eating occasions for which the children might have had more control. Interventions need to incorporate new procedures to more directly target intake at breakfast and dinner.
