Clinical Trial Summary

The aim of this study is to compare different sugary drink labels to see which most influence knowledge, beliefs, purchase intentions and choices. Parents of children ages 6-11 will shop in a virtual convenience store after being randomized to 1 of 4 conditions: 1) calorie labels; 2) text warning labels; 3) graphic sugar warning labels; or 4) graphic health warning. This study will provide data comparing the influence of sugary drink text warning labels and two kinds of graphic warning labels.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hypothetical beverage choice	Participants will select a beverage to purchase in the virtual store. Our outcome will be the percentage of parents choosing a 20-ounce sugary drink for their child	The survey will take up to 20 minutes
Secondary	Likely to serve or buy these beverages:	Item: "How likely are you to serve or buy this product for your child in the next 4 weeks?" This will be answered on a 7-point Likert scale.	The survey will take up to 20 minutes
Secondary	Parent feels good serving the beverages	Item: "Serving this product to my child would make me feel like I am doing something good for my child." This will be measured on a 7-point likert scale.	The survey will take up to 20 minutes
Secondary	Child enjoyment of beverages	Item: "How much do you think your child would enjoy this product?" This will be answered on a 7-point likert scale.	The survey will take up to 20 minutes
Secondary	Health beliefs and risk perceptions index	We will create this outcome by summing responses to the following 7 health perception questions 6 prompted with the statement "Drinking this product often would…". The statements end with the following health belief and risk perception language: "lead my child to gain weight," "increase my child's risk of heart disease," "increase my child's risk of diabetes," "make my child feel energized," "help my child focus at school", and "help my child live a healthy life." The other item is: "How healthy do you think this product is for your child?" Responses to questions about weight gain, heart disease, and diabetes will be reverse coded, so higher scores on the index will indicate a stronger positive health perception of the beverages. These will be scored on 7-point likert scales.	The survey will take up to 20 minutes
Secondary	Estimate of how many teaspoons of added sugar are in the beverages	This variable will be measured continuously based on a text box provided to participants.	The survey will take up to 20 minutes
Secondary	Perceived amount of added sugar in beverages	This variable will be measured on a 3-point Likert scale ranging from "too little for my child" to "too much for my child".	The survey will take up to 20 minutes
Secondary	Noticing the label	Participants will respond "yes," "no," or "I don't know" to the item: "When you selected a beverage to buy for your child at the beginning of this survey, did you notice any labels on the beverages other than calorie information?"	The survey will take up to 20 minutes
Secondary	Perceived label influence	Participants will respond: "yes", "no," or "I did not notice any labels" in response to the question of whether the label influenced their purchase.	The survey will take up to 20 minutes
Secondary	Favor or oppose sugary drink warning label policy	We will compare the percentage of participants in favor of (combining somewhat favor and strongly favor), opposed to (combining somewhat oppose and strongly oppose), or neutral about the policy based on the following question: "Would you favor or oppose a government policy requiring a warning label to be placed on beverages with added sugars?" Ratings will be from -2 to 2.	The survey will take up to 20 minutes
Secondary	Likelihood of label changing thoughts	Item: "If this government warning label were on a beverage, how much would it change your thoughts about the healthiness of that beverage for your child?" This will be measured on a 5-point Likert scale.	The survey will take up to 20 minutes
Secondary	Encourage you to give fewer beverages to your child	Item: "If you saw this government warning label on a beverage, would the label encourage you to serve your child that beverage less often?" The responses will be measured on a 5-point Likert scale.	The survey will take up to 20 minutes
Secondary	How much do you trust the information on this label	Item: "How much do you trust the information on this label?". Responses will be measured on a 7-point Likert scale.	The survey will take up to 20 minutes
Secondary	Negative reactions to the label	We will examine the average negative emotional response to the label (said the warning label made them feel worried, fearful, guilty, or disgusted or grossed out). Each emotion will be scored on a 5-pt likert scale.	The survey will take up to 20 minutes
