Brief Summary

Food insecurity is associated with an increased risk of obesity. The availability of a default option (i.e., option a consumer selects if no active choice is made) has been shown to effectively nudge consumer behavior. An online default option (i.e., prefilled grocery shopping cart) was previously shown to positively impact the food purchases of individuals with food insecurity.The present study aims to extend these findings bye examining efficacy of an online default option in enhancing the nutritional quality of online grocery purchases in individuals with food insecurity over the course of a month.

Default Intervention

EXPERIMENTAL

Participants in the default condition were presented with a pre-filled online shopping cart containing a combination of groceries that meet macro- and micronutrient requirements for their gender and age, and told that they are free to delete, add, and exchange any item they wish to finalize their selections.

Behavioral: Default Option

Nutrition Education

ACTIVE COMPARATOR

Participants in the nutrition education condition were instructed to read brief nutrition education handouts before online grocery shopping.

Behavioral: Nutrition Education

Interventions

Default OptionBEHAVIORAL

The default option is a behavioral economics construct that refers to the option a consumer selects if no active choice is made (e.g. opt-out 401K plans, which significantly increase enrollment, compared to active sign up). Participants in the default condition were presented with a prefilled online shopping cart containing groceries that met nutritional requirements based on participants' gender and age.

Default Intervention
Nutrition EducationBEHAVIORAL

The nutrition education materials were adapted from materials currently utilized by the Supplemental Nutrition Assistance Education Program
