What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Message acceptance	Message acceptance will be measured by five-item perceived message effectiveness questionnaire, such as the extent to which the message was worth remembering, grabbed their attention, powerful, convincing, and meaningful on a scale from 1 (Strongly disagree) to 5 (Strongly agree).	20 minutes
Harm perceptions	Harm perceptions will be measured by four-item e-cigarette harm perceptions questionnaire, such as the extent to which vaping is safe, contain flavors that are safe to use, contain dangerous chemicals, and harmful to health on a scale from 1 (Strongly disagree) to 5 (Strongly agree).	20 minutes

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Psychological reactance	Psychological reactance will be measured by six-item reactance questionnaire, such as perceptions of messages being manipulative, misleading, distorted, overblown, exaggerated, and overstated on a scale from 1 (Strongly disagree) to 5 (Strongly agree), and a four-item anger scale, measuring the extent to which the messages made participants feel irritated, angry, annoyed, and aggravated on a scale from 1 (not at all) to 5 (very much).	20 minutes
Message liking	Message liking will be measured by a single-item liking of the message on scale from 1 (Dislike very much) to 5 (Like very much).	20 minutes
Source trust	Source trust will be measured by a single-item trust in health information source questionnaire, such as trust in source about vaping information on a scale from 1(Not at all) to 5 (Very much so).	20 minutes
Attitudes	Attitudes will be measured by seven-item vaping attitudes questionnaire, such as vaping is unenjoyable/enjoyable, unhealthy/healthy, dangerous/safe, boring/fun, stupid/smart, not cool/cool, and not attractive/attractive on a five-point bipolar scale.	20 minutes
Behavioral intentions to vape or try vaping	Behavioral intentions to vape will be measured by a three-item behavioral intentions questionnaire, such as intentions to vape (for vapers)/try vaping (for non-vapers) soon, anytime during the next year, would use offered by one of their best friends on a scale from 1 (Definitely not) to 5 (Definitely yes).	20 minutes
