The Recipe for Response: Data Collection Methodologies of a National Food Diary Survey

Thomas M. Menino Convention & Exhibition Center 

The National Household Food Acquisition and Purchase Survey (FoodAPS) is a complex data collection initiative with high respondent burden. The survey begins with a primary household respondent but then, where applicable, expands to invite additional household members. Historically, the survey captures seven days of food acquisition data from all members of a household, in addition to extensive demographics of the household and a debriefing survey.
To optimize data collection, we experimentally implemented an alternative incentive structure and a shorter reporting period. Our analyses assess the causal impact of these interventions on response rates, data completeness and quality, and survey cost. Additionally, we examine the impacts of the non-experimental use of proxy reporting throughout the survey design. This research aims to provide practical guidance for survey methodologists on optimizing incentive strategies, determining ideal reporting length, and effectively utilizing proxy reporting to enhance data quality and participation in complex diary surveys.
