Overview

This is a Master ClinicalTrials.gov Protocol for study 20-01796: Aim 1: Examining Influence of Social Media Ads on Black and White Adolescents' Food Choices - Study 1 (NCT05380505) Aim 2: A Randomized Trial to Examine the Influence of "Likes" in Social Media Food Ads on Black and White Adolescents' Food Purchases - Study 2 (NCT06969638) Aim 3: Comparing the Effects of Racial Congruence, "Likes," and Food Images in Social Media Ads on Adolescents' Caloric Intake - Study 3 (NCT06969651)

Detailed description

The overall objective is to determine the extent to which racially congruent Facebook food ads influence adolescents' food purchases and actual caloric intake. The investigators are conducting three randomized controlled trials (RCTs). The first two aims involve 15-minute online surveys in which participants (Black and White adolescents) rate ads then complete a "food purchasing" task through a virtual vending machine. The third trial will involve an in-person, hour long lab study where participants will be shown ads while investigators covertly monitor their eye movements.
