简要总结
This study aims to develop a restaurant menu label to indicate foods and beverage items on restaurant menus that contain high amounts of added sugars and to test its perceived effectiveness.
详细描述
Objectives and hypotheses:
The goal of this study is to examine how added sugar restaurant menu labels influence U.S. adults' perceptions and reactions. Predictions:
In a between-subjects experiment with 3 arms (control label, icon-only added sugars label, and icon plus text added sugars label):
- Added sugar labels will be perceived as more effective than the control label.
- The text plus icon label will be perceived as more effective than the icon-only label.
- A larger proportion of participants who see the added sugar labels will report learning something new than those who see the control label.
- Added sugar labels will lead participants to more accurately identify restaurant menu items high in added sugars compared to the control label, and the text plus icon label will outperform the icon-only label on this outcome.
Additionally, using a within-subjects design:

研究组 & 干预措施
Control label
Participant will see a QR code and footnote saying, "Scan the QR code for more menu information." The label will be applied to all menu items displayed.
干预措施: Menu label (Other)
Icon plus text added sugars label
Participant will see a label containing an icon plus text label with an explanatory footnote. The label will be applied to items high in added sugars (exceeding half the daily value). Participants will randomly view one of 18 variations of icons and text in this arm.
干预措施: Menu label (Other)
Icon only added sugars label
Participant will see a label containing an icon only with an explanatory footnote. The label will be applied to items high in added sugars (exceeding half the daily value). Participants will randomly view one of 6 variations of icons in this arm.
干预措施: Menu label (Other)
结局指标
主要结局
Perception of how discouraging the label is for wanting to consume items high in added sugars
时间窗: Up to approximately 7 minutes
Based on a single item adapted from Baig et al. (2018): "This label discourages me from wanting to consume menu items high in added sugar" (scale 1-5). This outcome is the within-subjects objectives.
Perception of knowledge gain
时间窗: Up to approximately 1 minute
Dichotomous response (yes/no) to the question, "Did you learn something new from this label?" This outcome is for the between-subjects experiment.
Perceived message effectiveness (PME)
时间窗: Up to approximately 5 minutes
Measured using 3 items adapted from Baig et al. (2018): scale 1-5, "This label makes me concerned about the health effects of consuming menu items high in added sugars", "This label makes consuming menu items high in added sugars seem unpleasant", "This label discourages me from wanting to consume menu items high in added sugars." This outcome is for the between-subjects experiment.
Correct identification of items high in added sugars
时间窗: Up to approximately 2 minutes
"Now please look at the menu items below, and select all the ones you think have more than half the daily value for added sugars" with 8 possible responses. A dichotomous outcome variable based on the distribution of correct answers in the sample will be created. This outcome is for the between-subjects experiment.
