Adapting, refining and expanding a validated questionnaire to measure food waste in U.S. households.

ABSTRACT: The Household Food Waste Questionnaire (van Herpen et al. 2019a) was developed and validated as an effective instrument to identify statistically significant differences between households and to distinguish trends in household food waste over time. The original instrument was validated using consumers sampled from several European countries. We conduct a pilot study with U.S. consumers using the revised questionnaire. We find that a sample of 150 online panelists provided sufficient statistical power to replicate standard findings from the literature that smaller households and older respondents generate less food waste, but not enough statistical power to identify a statistically significant week-to-week reduction in reported food waste among households who received a food waste message
