Using Reinforcement Schedules to Increase Fruit&Vegetable Intake, Reduce Waste, and Increase School Lunch Participation

Using small monetary rewards to reinforce healthy behaviors, such as the consumption of fruits and vegetables (F&V), the investigators tested fixed and variable reinforcement schedules in three middle schools.

The investigators measured carotenoid levels, as a biomarker of F&V intake, and F&V waste over the intervention time frame. The investigators also tracked the school lunch participation rates over time.
