Summary

Adolescents (N = 664) participated in the online survey-based experiment. They were randomly shown 10 videos, featuring influencers promoting e-cigarettes alongside healthy lifestyle activities (experimental group), or e-cigarette promotion alone (control). After watching each video, participants rated perceptions of influencer credibility (i.e., honesty, trustworthiness, knowledge) on the scale of 0 (e.g., dishonest) to 100 (honest). Among all participants, harm perceptions and appeal of e-cigarettes was assessed. Susceptibility to use e-cigarettes was assessed among never users of e-cigarettes. These outcomes were then compared among participants who perceived influencers as credible and those who perceived influencers as non-credible.
