About this study

Official title: Graphic Messages to Prevent E-Cigarette Use Among Latino and African American Adolescents: A Randomized Controlled Trial

What is being measured

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

  1. Change in Percentage of Participants Susceptible to Future Vaping

    Susceptibility to future vaping was assessed before and after exposure to the graphic messages. Informed by prior foundational research on youth electronic cigarette use, susceptibility was measured with three items assessing curiosity, intent, and social influence. Participants were asked, "Have you ever been curious about using e-cigarettes/vaping?", "Do you think that you will use e-cigarettes/vape in the next 12 months?", and "If one of your best friends were to offer you an e-cigarette/electronic vapor product, would you use it?" (1 = "Definitely not" to 4 = "Definitely yes"). Responses were dichotomized: participants were categorized as susceptible if they answered anything other than "Definitely not" to at least one item. The percentage of susceptible participants was calculated before and after exposure; change in percentage reflects the difference.

    Measured: baseline to post-intervention, approximately 1 day

Secondary outcomes (2)
  1. Percentage of Participants Satisfied or Very Satisfied With the Graphic Message

    Satisfaction with the assigned vaping prevention graphic message was assessed using the item: "How satisfied are you with the image?" Responses were recorded on a 5-point Likert scale from 1 = "Extremely unsatisfied" to 5 = "Extremely satisfied." Participants selecting 5 ("Extremely satisfied") were categorized as satisfied. The percentage of satisfied participants was calculated per group. Higher percentages indicate greater satisfaction with the message.

    Measured: Day 1

  2. Percent of Participants Who Would Recommend the Graphic Message to a Friend

    participants were asked, "Would you recommend this picture to a friend?" with response options of Yes or No. The percentage of participants who responded "Yes" was calculated per group. Higher percentages indicate greater endorsement of the message.

    Measured: Day 1
