Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research is to study how the price of foods affects food buying choices at the grocery store. The researchers are interested in this topic because the price of foods can have a big impact on what people choose to buy and prices change over time. The researchers are doing this study to see how changes in food prices affect what foods mothers choose for their families.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is well known that the price of a given food affects the amount of that food an individual purchases. However, little is known about how specific groups, such as overweight/obese and those with lower incomes, change their food purchasing decisions depending on food price changes. Evidence has shown that these groups have lower quality diets and worse health outcomes than their normal weight and higher income counterparts. Therefore, it is important to gain a better understanding of how food price changes affect purchasing decisions among these populations in order to develop targeted nutrition interventions to improve their diet quality. To investigate this, the researchers will create a laboratory-based grocery store, in which pictures of foods will be used to substitute actual food. Food prices will be indicated on each picture. Participants will be given play money and a budget, and ask them to "purchase" foods in the mock grocery store. The price of food will be changed throughout the study to investigate how participants change their purchasing decisions based on these price changes.

Allocation Method

RANDOMIZED

Intervention Model

FACTORIAL

This study will utilize a three factor design, with one between-subject factor and two within-subject factors. The between-subject factor is participation in a federal food assistance program. The within-subject factors are price change condition and price change scenario.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Own-Price Elasticity

The price of fruit will vary (own-price elasticity) while the price of all other foods in the "mock" grocery store will remain constant.

Group Type EXPERIMENTAL

Own-Price Elasticity

Intervention Type OTHER

The price of fruit will be 75%, 100%, or 125% of the reference price, but the price of other foods will remain the same.

Cross-Price Elasticity

The price of fruit will remain constant while the price of other foods in the "mock" grocery store will vary (cross-price elasticity).

Group Type EXPERIMENTAL

Cross-Price Elasticity

Intervention Type OTHER

The price of fruit will remain the same, but the price of other foods will be 75%, 100%, or 125% of the reference price.
