Sugary Drink Labeling Study

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

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.

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.

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.

Measured using 1 survey item: "Did you learn something new from the labels?" where response options are "Yes" (coded as 1) and "No" (coded as 0).

The survey will show 6 drinks in random order, asking participants "Is this product high in sugar?" with response options of "No", "Yes", and "Don't know." 4 of the drinks will be high in added sugar and 2 will not be high in added sugar. Participants will be coded as "yes" (coded as 1) for correctly identifying beverages high in added sugar if they answer all 6 questions correctly.

Measured using 1 survey item: "How much did the labels make you think about the health problems caused by sugary drinks?" The 5-point response scale ranges from "Not at all" (coded as 1) to "A great deal" (coded as 5). Higher scores indicate greater thinking about harms of sugary drinks.

Measured using 1 survey item: "How healthy or unhealthy are sugary drinks?" The 5-point response scale ranges from "Very unhealthy" (coded as 1) to "Very healthy" (coded as 5). Higher scores indicate greater perceived healthfulness of sugary drinks.
