Change in overall score of the healthfulness of foods purchased, weighting the proportion of red, yellow, and green foods. To calculate the score, red foods are weighted 0, yellow are weighted 0.5, and green foods are weighted 1.0. Weighted scores are multiplied x 100, and the range is from 0 (least healthy cafeteria purchases, i.e. all red) to 100 (healthiest cafeteria purchases, i.e. all green).
