About this study

Official title: Examining Influence of Social Media Ads on Black and White Adolescents' Food Choices: Master ClinicalTrials.Gov Protocol for Aim 1 (NCT05380505), Aim 2 (NCT06969638) and Aim 3 (NCT06969651).

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)

Read the 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.

Study groupRoleWhat they receive
(Aim 1) Condition 1: Race Congruent AdsExperimentalParticipants will complete a 15-minute survey in which they will be randomized to view and rate Facebook food 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Calories Purchased

    Aim 1 Participants only.

    Measured: Day 0 (approximately 15 minutes )

  2. Number of Calories Purchased

    Aim 2 Participants only.

    Measured: Day 0 (approximately 5 minutes)

  3. Caloric Intake

    Aim 3 Participants only. Number of calories consumed during the study protocol.

    Measured: Day 0 (approximately 60 minutes)

  4. Visual Attention to Ad Features - First Fixation

    Aim 3 Participants only. Measured as time to first fixation to the advertisement.

    Measured: Day 0 (approximately 60 minutes)

  5. Visual Attention to Ad Features - Gaze Duration

    Aim 3 Participants only. Measured as the gaze duration during the advertisement.

    Measured: Day 0 (approximately 60 minutes)

  6. Visual Attention to Ad Features - Number of Fixations

    Aim 3 Participants only. Measured as the number of fixations on ad features.

    Measured: Day 0 (approximately 60 minutes)

Secondary outcomes (4)

  1. Attitude Toward Ad

    Aim 1 Participants only. Attitude will be reported on a Likert scale of 1 to 100 (1 = likeable, 100 = unlikeable). The higher the score, the less likeable the ad is to the participant.

    Measured: Day 0 (approximately 15 minutes )

  2. Time Spent Viewing Ad

    Aim 1 Participants only.

    Measured: Day 0 (approximately 15 minutes )

  3. Attitude Toward Ad

    Aim 2 Participants only. Attitude will be reported on a Likert scale of 1 to 100 (1 = likeable, 100 = unlikeable). The higher the score, the less likeable the ad is to the participant.

    Measured: Day 0 (approximately 5 minutes)

  4. Engagement with Ads

    Aim 2 Participants only. Participants indicate in which ways, if any, they would engage with each ad by answering the following question: "How you would respond if you saw this ad on social media"? [Select all that apply: "Like" [heart icon and other emojis], comment, tag a friend, direct message a friend, re-post, none of the above]). The outcome is measured as the number of participants who indicate they would engage with ads.

    Measured: Day 0 (approximately 5 minutes)
