Fast Food Photo Study

Not Applicable

Completed

• Conditions: Obesity
• Interventions: Other: Menu edited

• Registration Number: NCT02267954
• Lead Sponsor: Carnegie Mellon University

Brief Summary

The investigators aim to discover if people of different demographic levels are more or less attentive to changes in calorie information vs. changes in price information on a restaurant menu. The investigators will record whether the calorie/price change was noticed or not, as well as how quickly the calorie/price change was noticed, depending on condition and individual differences.

Detailed Description

Participants complete a short study regarding their ability to detect "mistakes" in a printed version of a fast food restaurant menu. We ask participants to identify the differences between the menu board and a typical menu board at that location. Individuals list the differences that they find and have a chance to win a prize if they identify the most mistakes among participants recruited that day. The differences created will remain constant (e.g., featuring Pepsi products instead of the typical Coca-Cola offerings, including items from other restaurants on the menu), including changes to calorie labels and price labels. Additionally, we recruit participants in a variety of locations to test for differences between demographics (e.g., income groups, education levels, and BMI levels).

Arm && Interventions

Group	Intervention	Description
50% Prices/50% Calories	Menu edited	The participant is exposed to the baseline menu, but the prices are edited to be at 50% of the actual price (e.g., a $1 coffee is listed as costing $.50) and the calorie labels are edited to be at 50% of the actual content (e.g., a 500 calorie Large Fries is listed as having 250 calories). In addition, the baseline mistakes are still included. This is the "Menu edited" intervention.

Primary Outcome Measures

Name	Time	Method
Calorie and Price Mistakes Noticed	10 minutes	Did participants indicate that a mistake was present in the calorie labels or price labels?

Secondary Outcome Measures

Name	Time	Method
Time until Calorie and Price Mistakes Noticed	10 minutes	How long in seconds did it take before participants indicated that a mistake was present in the calorie labels or price labels?
Mistake Number for Calorie and Price Mistakes Noticed	10 minutes	How many other mistakes were noticed before calorie/price mistake was noticed?
