The investigators will use a between-subjects randomized experiment to assess the primary outcome. Participants will be randomized to one of five label conditions modeled after the U.S. Food and Drug Administration's draft \"High In\" FOPL designs: 1) No Icon; 2) Magnifying Glass; 3) Exclamation Mark; 4) Exclamation Mark with multiple labels; 5) Exclamation Mark with Black Background.\n\nThe primary outcome is correct identification of the healthiest product, defined as the product that is high in the fewest nutrients of concern, including added sugars, sodium, and saturated fat (percent correct for each condition). Secondary outcomes include correct identification of which product is least healthy; which product(s) are high in added sugars, saturated fat, and sodium (3 separate questions); and perceived message effectiveness (PME) of the different labels.\n\nLogit models will be used to compare proportions in each condition that correctly identified the items (each condition compared to every other condition). For continuous outcomes (e.g., knowledge, PME scale), the investigators will use linear regression models regressing the outcome on an indicator for experimental condition. A critical alpha 0.05 will be used, and statistical tests will be two-tailed. The Bonferroni Holm correction will be used for analyses comparing conditions 2-5 to each other for each outcome (6 comparisons).\n\nThe investigators will also measure nutrition literacy, and assess moderation on the primary outcome by nutrition literacy (continuous) and highest education attainment (Bachelor's Degree or higher vs. less than Bachelor's Degree)."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "maximumAge"=>"99 years", "minimumAge"=>"18 years", "healthyVolunteers"=>true, "eligibilityCriteria"=>"Inclusion Criteria:\n\n* Equal or greater than 18 years of age\n* Less than 100 years of age\n* English-speaking\n* U.S. residents\n* Participants will reflect the U.S. Census Bureau's 2021 American Community Survey 5-year estimates for gender, race/ethnicity, educational attainment, and age\n\nExclusion Criteria:\n\n* Failing the attention check question\n* Completing the survey in less than 33% of the median completion time"}, "identificationModule"=>{"nctId"=>"NCT06227507", "briefTitle"=>"High in Front-of-package Label Pretest", "organization"=>{"class"=>"OTHER", "fullName"=>"University of California, Davis"}, "officialTitle"=>"FDA Front-of-package Pretest: High In Labels", "orgStudyIdInfo"=>{"id"=>"1641776-7"}}, "armsInterventionsModule"=>{"armGroups"=>[{"type"=>"EXPERIMENTAL", "label"=>"No icon", "description"=>"Participants will be shown 3 frozen meals at once; each product will be high in 1, 2, or 3 nutrients of concern (added sugar, sodium, and/or saturated fat) and will be labeled as such with a rectangular \"high in\" front-of-package label.
