Study Details

Randomized and controlled experimental study to evaluate how influencer food ads on TikTok affect calorie purchases among youth (ages 10-13). Participants will be randomized to one of two conditions: (1) seeing an influencer with food or (2) seeing an influencer without food. Participants will complete a 15-minute survey in which they will be randomized to one of two conditions and view and rate TikTok influencer ads associated with their condition. Then they will complete a food purchasing task in which they will shop in an online store that will display six food items and six beverages. Finally, they will answer demographic questions (e.g., self-reported height and weight) and view a debriefing summary that describes the full purpose of the study.

Arms

  • Experimental: TikTok Influencer Ads with Food
    Participants randomized to view TikTok influencers' posts with food will view 4 ads associated with their condition and 2 filler ads, all of which are presented in counterbalanced order. They will report their reaction to the ads using the icons available on the TikTok platform (i.e. like, comment, or share). After viewing all of the TikTok ads, youth participants will complete the virtual snack selection task where they will see a virtual vending machine. All items will cost $2. Participants will be asked to select one snack and one beverage from the vending machine. After the snack selection task, participants will review the TikTok ads again and complete survey questions.
