Sugary Drink Labeling Study

Amount of added sugars purchased from sugary drinks

Measured using purchase data for sugary drinks, defined as drinks that contain at least 20% of the daily value for added sugar. The total amount of added sugars (in grams) in all sugary drinks purchased will be calculated.

Amount of total sugars purchased from all beverages

Measured using purchase data for all drinks. The total amount of total sugars (in grams) in all drinks purchased will be calculated.

Volume of sugary drinks consumed in the past 7 days

Measured using survey items adapted from the 15-item beverage intake questionnaire (BEV-Q 15) measure. The survey items assess frequency of consumption of sugary drinks and typical volume of sugary drinks consumed in the past 7 days. Researchers will multiply frequency by typical volume to estimate the total volume of sugary drinks consumed in the past 7 days, reported in fluid ounces.

Intentions to reduce sugary drink consumption

Measured using 3 survey items: 1) "How interested are you in drinking fewer sugary drinks in the next week?" 2) "How much do you plan to drink fewer sugary drinks in the next week?" and 3) "How likely are you to drink fewer sugary drinks in the next week?". Response options are on a 5-point scale with lowest endorsement coded as 1 and highest endorsement coded as 5. Researchers will average responses to the 3 items to create a scale score. Higher scores indicate greater intentions to reduce sugary drink consumption.

Forgoing sugary drinks

Measured using 5 survey items asking participants how often they chose to forgo sugary drinks during the study (e.g., "In the last 7 days, how often have you stopped yourself from having sugary drinks because you wanted to cut back?"). Response options are on a 5-point scale ranging from "Never" coded as 0, to "10 or more times", coded as 10. Researchers will average responses to the 5 items. Higher scores indicate greater frequency of forgoing sugary drinks.
