Nudging for Behavior Change in School Cafeterias

Status Completed

Clinical Trial Summary

The main purpose of this research is to look at a school lunchroom intervention that is known to improve fruit, vegetable, and milk consumption and see how it changes in the long run and if it affects the child's behavior permanently. The intervention will include the giving the vegetables descriptive names, moving the fruit to right next to the register and in attractive bowls, and increasing the amount of white milk served by 10%. The main forms of analyzing these results are through food preparation records, lunch sales records, and tray waste records. The first focus of this study is to see if there is a specific point in an intervention when improvement stops and therefore the intervention needs to be updated. This procedure involves looking at five similar middle schools with this same intervention over a 15 week period. The time of intervention implementation will vary by three week intervals, so the first will start the first week of school, the next school will start after three weeks of school, the next will start after six weeks of school, and the next will start after nine weeks of school, and the last will be a control school where there will be no intervention implementation. These intervals will help eliminate bias dealing with the beginning of the year excitement and seasonal effects. Food preparation records and lunch sales records will be collected from the school for the 15 week period. Tray waste will be recorded by having 200 randomly selected trays measured and collected twice a week over the 15 week period. This focus will help schools manage when they need to change their intervention so that improvements will not stop. The second focus of this study is to see if the children's improvement is kept when the intervention has stopped. This procedure will involve looking at a similar school to the other 5 schools. But unlike the other schools, this one will have the first 5 weeks without the intervention, then 5 weeks with the intervention, and then another 5 weeks without the intervention. Food preparation records and lunch sales records will be collected from the school for the 15 week period. Tray waste will be recorded by having 200 randomly selected trays measured and collected twice a week over the 15 week period. This second focus will help identify how effective this intervention is in permanently changing dietary habits.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
