Outcome Measures

Primary Outcomes (2)

  • Noticing and recall of added-sugar nutrient label - dichotomous variable "Correct" (Answered "Yes" to noticing, answered "Added sugars" to recall, and answered "high" for high low recall question) or "Incorrect" (otherwise)

    Noticing a nutrition label - Measured with "Think back to the beginning of this survey when you imagined you were ordering dinner from restaurant menus. Did you notice any nutrition labels (other than the calories) next to any of the menu items?" Response options are "Yes", "No", and "Don't know". Recalling the label's meaning - \[If answered "Yes"\] Measured with "What did the nutrition label tell you about?" Response options are (displayed in survey in a random order) "Sodium", "Added sugars", "Trans fats", "Fiber", "Calcium", "Healthy items", "Unhealthy items", "Vegetarian", "Organic", "Gluten-free", "Sustainable", "None of these", "Not sure". High/low - \[If answered "Added sugars"\] "What did the label tell you about added sugars?" Response options are "High in added sugars", "Low in added sugars", "Something else", "I don't know". There is no formal name for this measure/scale.

    up to approximately 1 minute

  • Recognition of label - dichotomous variable "Correct" (selected the label they were assigned to" or "Incorrect" (any other option).

    Measured with "Please look at the following labels and select which label (if any) you saw on the menus while selecting your food and beverage items." Response options will include images of 7 labels with the designs based on the participant's assigned color (black vs red) and label type (icon-only vs. boxed-icon vs, boxed icon-plus-text label) and the options, "Not sure" and "None of these". There is no formal name for this measure/scale. It was developed for this study.

    up to approximately 1 minute

Secondary Outcomes (2)

  • Knowledge of menu items high in added sugar - continuous variable using the percent of 8 items correctly classified

    up to approximately 2 minutes

  • Perceived Message Effectiveness of label - continuous variable based on a 3-item scale in which each item uses a 1-5 response scale

    up to approximately 2 minutes

Other Outcomes (4)

  • Selection of at least one item high in added sugar

    up to approximately 2 minutes

  • Grams of sugar ordered

    up to approximately 2 minutes

  • Perception that the labels grabbed attention

    up to approximately 1 minute

  • +1 more other outcomes
