Dynamic Presentation of Calorie Information

Study Overview
=================
Brief Summary
-----------------
Participants will be asked to select a hypothetical lunch from a menu that features entrees, sides, and drinks. Participants will be able to select a maximum of 1 item from each category. Following this meal selection, participants will complete a short survey about their demographics, their estimates of information about the meal and about recommended eating habits.

Detailed Description
-----------------
The presence or absence of calorie labels on the hypothetical lunch menu will be randomly assigned to participants. Participants will first be randomly assigned to either the numeric label survey or the light label survey, and then within that survey, participants will be randomly assigned to either a control (no label), an item-level label, or an item-level and meal-level label condition. Participants will select a hypothetical lunch from a menu that features entrees, sides, and drinks. Participants will be able to select a maximum of 1 item from each category. Following this meal selection, participants will complete a short survey about their demographics, their estimates of information about the meal and about recommended eating habits.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control 1<br>Participants in this group will see a menu labeled with prices, but will not observe calorie information. Used as a comparator for numeric labeling conditions. | |
| Experimental: Numeric individual<br>Features Item-Level Calorie information. Numeric calorie labels will be featured on individual items, along with prices. | Other: Item-Level Calorie information<br>* Information identifying the calorie content of individual items will be provided, as would be done on a restaurant menu board.<br>|
| Experimental: Numeric individual + aggregate<br>Features Item-Level Calorie information and Meal-Level Calorie information. Numeric calorie labels will be featured on individual items, along with prices. Additionally, an aggregated numeric calorie count for the entire meal will be dynamically updated as items are added or removed from the meal. | Other: Item-Level Calorie information<br>* Information identifying the calorie content of individual items will be provided, as would be done on a restaurant menu board.<br>Other: Meal-Level Calorie information<br>* Information from the calorie content of individual items that have been selected by the participant will be dynamically aggregated and presented as a Total Calories label on the menu screen.<br>|
| No Intervention: Control 2<br>Participants in this group will see a menu labeled with prices, but will not observe calorie information. Used as a comparator for light labeling conditions. | |
| Experimental: Light individual<br>Features Item-Level Calorie information. Traffic light calorie labels will be featured on individual items, along with prices. | Other: Item-Level Calorie information<br>* Information identifying the calorie content of individual items will be provided, as would be done on a restaurant menu board.<br>|
| Experimental: Light individual + aggregate<br>Features Item-Level Calorie information and Meal-Level Calorie information. Traffic light calorie labels will be featured on individual items, along with prices. Additionally, an aggregated traffic light label for the entire meal will be dynamically updated as items are added or removed from the meal. | Other: Item-Level Calorie information<br>* Information identifying the calorie content of individual items will be provided, as would be done on a restaurant menu board.<br>Other: Meal-Level Calorie information<br>* Information from the calorie content of individual items that have been selected by the participant will be dynamically aggregated and presented as a Total Calories label on the menu screen.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Calories ordered | Single survey presentation, measure of calories ordered collected as people select meal | 5 minutes after presentation of information | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Light category ordered | Single survey presentation, measure of what aggregated light the calories ordered would have qualified for. Collected as people select meal | 5 minutes after presentation of information | 
| Calories per category | Single survey presentation, measure of calories per entree, calories per side, and calories per drink selected, collected as people select meal | 5 minutes after presentation of information |
