Clinical Trial Summary

The goal of this study is to examine attention elicited by icon, text-only, and control front-of-package food labels. The study also aims to explore whether English language proficiency moderates the impact of icon vs. text-only labels on attention.

Description:

In this study, participants will attend one in-person visit, lasting approximately 15 minutes after signing informed consent. First participants will complete an eye tracking task where their attention to study stimuli is measured objectively via an eye tracker (i.e., eye tracking task). The eye tracking task will take ~5 minutes. Then, participants will complete a brief ~10 minute self-administered survey on a computer.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Amount of time spent looking at the front-of-package sodium label (i.e., dwell time)	This outcome will be measured using eye tracking technology.	During ~5-minute eye tracking task, as part of a one-time study visit lasting ~15 minutes
Secondary	Number of times looking at the front-of-package sodium label (i.e., fixation count)	This outcome will be measured using eye tracking technology.	During ~5-minute eye tracking task, as part of a one-time study visit lasting ~15 minutes
Secondary	Time to first fixation on the front-of-package sodium label	This outcome will be measured using eye tracking technology.	During ~5-minute eye tracking task, as part of a one-time study visit lasting ~15 minutes
Secondary	Dwell time on "natural" claim	This outcome will be measured using eye tracking technology.	During ~5-minute eye tracking task, as part of a one-time study visit lasting ~15 minutes
Secondary	Self-reported attention to the front-of-package sodium label	Assessed with 1 item for each label type. Response options will range from 1 to 5. Higher scores indicate more attention.	During ~10 minute online survey, as part of one-time study visit lasting ~15 minutes
Secondary	Perceived message effectiveness of the front-of-package sodium label	Assessed with 3 items for each label type. Response options will range from 1 to 5. Higher scores indicate greater perceived message effectiveness.	During ~10 minute online survey, as part of one-time study visit lasting ~15 minutes
Secondary	Understandability of front-of-package sodium label	1 item for each label type. Response options will range from 1 to 5. Higher scores indicate more understandability.	During ~10 minute online survey, as part of one-time study visit lasting ~15 minutes
