• Conditions: Vaping Behavior

• Registration Number: NCT06704295
• Lead Sponsor: Rutgers, The State University of New Jersey

Brief Summary

This randomized controlled trial aims to examine the effects of high-impact e-cigarette advertisement features among young adults of various tobacco-use statuses. Previous research on examining the effects of e-cigarette advertisement features found that flavor-related features (e.g., flavor-associated product color, name and image, flavor sensation descriptor, and flavor choice claim) may have the largest impact on shaping young adults' perceptions and use intentions of e-cigarettes. No research so far has solely focused on examining the effects of those high-impact flavor-related advertisement features. The present study assessed the effects of high-impact flavor-related advertisement features, including flavor descriptor name, e-cigarette product color (which indicates flavors), flavor-related image, flavor sensation descriptor, and flavor choice claim on perceptions and behavioral intentions among a large online sample of young adults aged 18-30 who either smoke cigarettes or do not use tobacco products. The study is a six-group RCT with parallel assignments that will be delivered through an online self-administered questionnaire consisting of one session. Participants will be randomly assigned to one of six trial arms: 1) dark gray product with tobacco flavor name, 2) dark gray product with strawberry flavor name, 3) colorful (strawberry color) product with strawberry flavor name, 4) colorful (strawberry color) product with strawberry flavor name and strawberry image, 5) colorful (strawberry color) product with strawberry flavor name, strawberry image, strawberry flavor sensation descriptor, and 6) colorful (strawberry color) product with strawberry flavor name, strawberry image, strawberry flavor sensation descriptor, and flavor choice claim. Participants will be exposed to one advertisement corresponding to the assigned condition, and answer survey questions immediately after message exposure.

Detailed Description

The FDA considers the marketing plans of new e-cigarette products for premarket tobacco product application approval. Flavor-related advertisement features may entice young adults who do not use tobacco products to use the products but may also generate complete product switching interests among young adults who smoke cigarettes. This study tested the effects of several high-impact e-cigarette advertisement features related to flavors to inform the FDA's policymaking and public health preventive messages.

Setting: The trial will be an experiment delivered through an online self-administered questionnaire consisting of one session over 20 minutes.

Recruitment: Participants will be recruited from the research company Qualtrics from its research panels.

Informed Consent: Participants will provide online consent prior to taking the survey.

Randomization: After providing informed consent and answering pre-exposure questions, the investigator will use Qualtrics programming to randomize participants into one of the six trial conditions. The randomization will use least fill for the allocation of conditions where if the counts for the conditions were equal, the survey would assign the condition sequentially.

Assessment: Participants will take part in one session (estimated at about 20 mins): participants will answer questions assessing tobacco use status, cigarette smoking quit intentions and attempts (only asked young adults who smoke cigarettes), e-cigarette use, and other tobacco product use. They will then view one e-cigarette advertisement for at least 12 seconds and report immediate outcomes, including perceptions and behavioral intentions related to the e-cigarette product they see in the advertisement.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 3083

Inclusion Criteria

• Three groups of young adult subjects will be included in the study. The first group is those who are exclusive cigarette smokers (n=1000), defined as those who have smoked at least 100 cigarettes in their lifetime and have smoked at least one cigarette in the past 30 days but have not used e-cigarettes in the past 30 days. The second group is those who are dual users of cigarettes and e-cigarettes (n=1000). Those in this group have smoked more than 100 cigarettes in their lifetime and have smoked a cigarette and also used an e-cigarette in the past 30 days. The third group is those who are non-tobacco users (n=1000), defined as those who have never used any tobacco product before or have never "regularly" used tobacco products before and are currently not using any tobacco products (in the past 30 days).

Exclusion Criteria

• Any subjects not meeting the inclusion criteria will be excluded from the study. Individuals will be further excluded if they do not provide consent to participate in the study.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Intentions of using the e-cigarette	Immediately after exposure	A single item measuring the intentions of using the e-cigarette shown in the ad. Response options are from 0 (Extremely unlikely ) to 10 (Extremely likely).
Intentions of switching completely to the e-cigarette	Immediately after exposure	A single item measuring participants' intentions of switching completely to the e-cigarette shown in the ad. Response options are from 0 (Extremely unlikely ) to 10 (Extremely likely). This question is only asked among those who smoke cigarettes.

Secondary Outcome Measures

Name	Time	Method
Intentions of using the e-cigarette compared to cigarettes	Immediately after exposure	A single item measuring the intentions of using the e-cigarette shown in the ad compared to smoking cigarettes. Response options are from 0 (Much less likely ) to 10 (Much more likely).
Intentions of using the e-cigarette compared to other e-cigarettes	Immediately after exposure	A single item measuring the intentions of using the e-cigarette shown in the ad compared to using other e-cigarette products. Response options are from 0 (Much less likely ) to 10 (Much more likely).
Ad appeal	Immediately after exposure	A 3-item scale for those who do not use tobacco, measuring to what extent participants perceive the ad they saw to be appealing, including liking the ad, curious about the product shown in the ad, and interest in using the product shown in the ad. Response options are from 0 (Dislike very much ) to 10 (Like very much) for ad liking and 0 (Strongly disagree) to 10 (Strongly agree) for the other two items. A 4-item scale for those who smoke cigarettes, including the same 3-item scale and an additional single item measuring the agreement on whether the ad makes them want to completely switch to the e-cigarette shown in the ad. Response options are from 0 (Strongly disagree) to 10 (Strongly agree).
Perceived absolute harm of using the e-cigarette	Immediately after exposure	A single item measuring the participants' perception of having health problems from using the e-cigarette shown in the ad. Response options are from 0 (Extremely unlikely ) to 10 (Extremely likely).
Perceived absolute addictiveness of using the e-cigarette	Immediately after exposure	A single item measuring the participants' perception of becoming addicted to using the e-cigarette shown in the ad. Response options are from 0 (Extremely unlikely ) to 10 (Extremely likely).
