Brief Summary:
Young adults (N = 1,500) will participate in the online survey-based experiment. They will be randomly shown 10 videos, featuring influencers promoting e-cigarettes alongside healthy lifestyle activities (experimental group), or a healthy lifestyle activity alone (control). After watching each video, participants will rate perceptions of influencer credibility (i.e., honesty, trustworthiness, knowledge, attractiveness, intelligence, and popularity) on the scale of 0 (e.g., dishonest) to 100 (honest).
Among all participants, harm perceptions of e-cigarettes will be assessed. Susceptibility to use e-cigarettes will be assessed among never users. These outcomes will then be compared among participants who perceived influencers as credible and those who perceived influencers as non-credible.

Detailed Description:
Young adults (18-24 years of age) living in California were recruited by YouGov marketing research panel to participate in a survey on tobacco-related attitudes and behaviors. YouGov, a research panel agency, has been used in prior research to survey young adults about their tobacco-related attitudes and behaviors. Respondents (N=1,500) were matched to a sampling frame based on gender, age, race, and education. The sampling frame was a politically representative modeled frame of United States (U.S.) adults based on the American Community Survey. The matched cases were weighted to the sampling frame using a propensity score matching procedure. Participants were provided with a survey URL link. After completing informed consent, participants completed the survey online. The study was approved by the University of Southern California Institutional Review Board (UP-21-00135). Respondents were randomly assigned to watch 10 10-second long TikTok videos in either experimental (influencers promoting e-cigarettes alongside healthy lifestyle activities ) or control group (influencers showing healthy lifestyle activity alone).
