研究组 & 干预措施
Snackability app
This app allows user to search for a snack (scan barcode or type snack name), add a portion size consumed based on a portion size guide, and then provide a snack score and breakdown scores with a specific feedback message about the score.25 A score ranging from 0-10 points was designed taking into account the first ingredient, the nutrient standard by portion size, and the processing of foods (score ranging from -1 to 1 was subtracted or added depend on processed food classification). The final score ranged from -1 to 11 points. The higher the score, the more compliant it is to the guideline; therefore, the healthier the snack is. The app also provides gamification features as self-motivation (level up and achievement gained) and reporting features as goal-setting and self-monitoring (average daily score and consumed snack history).
干预措施: Snackability app (Behavioral)
Control group
The control group received a 1-page with information on what is a healthy snack from the USDA: https://www.fns.usda.gov/cn/tools-schools-focusing-smart-snacks. They were given access to the app after the 12-week study period.
