(USC TCORS P4)
What this study is about
The purpose of this study is to present social media posts with varying combinations of flavor types and mentions of stealth use, to adolescents and determine whether these message characteristics increase adolescents' perceptions of these products and susceptibility to using these products.
View original scientific description
The purpose of this study is to present social media posts with varying combinations of flavor types and mentions of stealth use, to adolescents and determine whether these message characteristics increase adolescents' perceptions of these products and susceptibility to using these products.
Interventions
BEHAVIORAL
Each intervention will be a picture of a social media post. The posts will vary (in a 3X2 factorial design) the type of flavor described and whether concealability is described.
The researchers are making stimuli that will appear to be social media posts about tobacco products. They will vary on two dimensions in a 3X2 design: Type of flavor portrayed (flavored, unflavored, or concept flavor name) Whether the post portrays the tobacco product as concealable
Primary outcome measures
Tobacco product use: Lifetime and past-month use of tobacco products Perceived harm of product Social norms about product use Susceptibility to tobacco use
Time frame: Immediately after viewing the stimuli
All of these are standard psychosocial measures from the Population Assessment of Tobacco and Health (PATH) survey.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
