Summary

The purpose of this study is to test the use of a smartphone app as a way to measure food waste.

Investigators propose to improve the accuracy and convenience of household food waste measurement so that consumer food waste program evaluations yield more power, less bias, less measurement error, and greater representation of targeted populations.

Conditions

  • Food Habits

Interventions

OTHER

Natural Environment/Stress Management

Participants will use the FoodImage app to capture data on food purchases, food waste that occurs during food preparation, food waste that is present after eating, and food waste from food purges in free-living conditions. Participants will capture baseline data for 4-7 days. After a 1-week break, participants will use the app to record food waste for approximately 4-7 days over the subsequent week. They will also receive information on stress management

BEHAVIORAL

Natural Environment/Reduce Food Waste

Participants will use the FoodImage app to capture data on food purchases, food waste that occurs during food preparation, food waste that is present after eating, and food waste from food purges in free-living conditions. Participants will use the app to record food waste for approximately 4-7 days over the subsequent week. They will also be provided with the following: 1. Feedback on the amount of food waste their household created during the first week, 2. A goal to reduce the next week's food waste by 20% or more, and 3. Tips on how to reduce household food waste adapted from current consumer campaigns
