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)

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.
