Inclusion Criteria:
- This research focused on food choices of middle school students, grades 6-8, which generally range in ages 11-14. In addition, since we are interested in learning about the types of cafeteria foods children select and what they throw away, we focus on students who receive a school lunch meal.
Exclusion Criteria:
- We exclude students who do not receive a school lunch meal.

Kein Eingriff: Control
In this school, we collected data throughout the entire study without implementing any intervention.

Experimental: 5-week Intervention with Post-intervention Data Collection
In this school, we collected baseline data for 5 weeks, implemented the intervention for five weeks, then removed the intervention and collected post-intervention data for five weeks.
|
The intervention consists of three components: 1) serving fresh fruit in attractive bowls in at least two locations on the lunch line; 2) providing descriptive names for the vegetables; and 3) increasing amount of plain milk availability by 10% and placing it in front of the chocolate milk.
For the vegetable naming intervention, researchers first developed, printed, and laminated descriptive vegetable name cards (2"x4").
Some examples included "Savory Collard Greens," and "[School Mascot] Salad."
Cafeteria staff affixed name cards to the serving line sneeze-guards in front of the vegetables for the day.
For the fruit intervention, we purchased and delivered two ceramic bowls to the intervention school.
The cafeteria staff filled the bowls and put them in different locations on the lunch line.
For the milk intervention, cafeteria staff increased the amount of plain milk available by 10% and placed plain in front of chocolate milk in the coolers.

Experimental: Implement intervention for 15 weeks
In this school, we implemented the intervention on January 11, 2016, the day the study began.

Percentage of students that took a serving of fruit
Zeitfenster: 30 days
|
To determine whether or not a student took a serving of fruit, we will rely on tray waste records that we collected twice a week (repeated measures) for the duration of the study.
Based on these records, if a student selected a serving of fruit, she will receive a value of one.
Otherwise, she will receive a value of zero.
We will use this binary measure to estimate the proportion of students who took a serving of fruit.

Percentage of fidelity assessments that returned positive marks
Zeitfenster: 36 days
|
Throughout the study, researchers conducted fidelity assessments to make sure the schools maintained the interventions.
These process control measures are the ratio of successful fidelity checks to the total number.
Researchers conducted these assessments during each day they collected tray waste measures and during a randomly selected non-tray waste collection date once a month.
