Clinical Trial Summary

This is a 2-arm, randomized controlled, population based trial to test the impact of multiple exposures to brief nicotine corrective messages among adult tobacco cigarette smokers and non-smokers followed in waves over 12 weeks. The primary outcome, assessed at wave 1 (baseline), wave 2 (weeks 5-6), and wave 4 (weeks 11-13) is nicotine beliefs. Secondary outcomes assessed at the same time points include intention to use nicotine/tobacco products and nicotine/tobacco use.

Description:

This is a 2-arm, randomized controlled, population based trial to test the impact of multiple exposures to brief nicotine corrective messages among adult tobacco cigarette smokers and non-smokers followed for 12 weeks. The primary outcome, assessed at wave 1 (baseline), wave 2 (weeks 5-6), and wave 4 (weeks 11-13) is nicotine beliefs. Secondary outcomes assessed at the same time points include intention to use nicotine/tobacco products and nicotine/tobacco use. All participants will be recruited from a US national consumer research panel. Eligible participants will be U.S. adults ages 18+ who are enrolled members of the partnering consumer research panel. The sample will include non-smokers and smokers, oversampling current smokers (defined as smoking 100+ lifetime cigarettes and now smoking all or some days) to ensure the proportion of smokers in the sample reflects the ~15 % population smoking prevalence among adults. Panel members will be contacted by email with a brief study description and link to an eligibility screener and online informed consent form. Eligible and interested participants will complete the baseline (Wave 1) survey measures of nicotine beliefs and intentions/use of nicotine and tobacco products, after which they will be randomly assigned in equal numbers to the nicotine corrective message (NCM) intervention condition or the delayed message control condition. After completing the baseline survey, participants in the NCM condition will receive their first exposure to the corrective messages. In the Wave 2 survey, all participants will complete measures of nicotine beliefs and intentions/use of nicotine and tobacco products. Participants in the NCM condition will then receive their second exposure to study messages. Only participants in the NCM condition will receive the Wave 3 survey, which involves the third exposure to study messages. The Wave 4 survey will include the fourth exposure to study messages for those in the NCM condition and the final assessment of nicotine beliefs and intentions/use of nicotine and tobacco products for all participants. Upon completion of the final assessment, participants in the control condition will be exposed to the nicotine corrective messages and all participants will be directed to resources on quitting smoking.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Attitudes About Nicotine	Three items on nicotine-related attitudes using semantic differentials across five-point Likert scales. 'Using Nicotine is:' Safe (1) - Dangerous (5); Positive (1) - Negative (5); Good (1) - Bad (5).	Wave 4 (weeks 11-13)
Other	Nicotine Related Norms	Two items: "How would you describe most people's opinion of using nicotine?" and "Thinking about the people who are important to you, how would you describe their opinion on using nicotine?" with five-point Likert scale responses ranging from "very negative" (1) to "very positive" (5). Higher scores indicate positive norms of using nicotine.	Wave 4 (weeks 11-13)
Other	Behavioral Control	One item assessing confidence to resist smoking cigarettes when others are smoking (1=not at all confident to 4=very confident).	Wave 4 (weeks 11-13)
Primary	Nicotine Beliefs	3 items assessing nicotine false beliefs (range 3-11), 6 items assessing nicotine replacement therapy (NRT) false beliefs (range 4-20), 4 items assessing e-cigarette false beliefs (range 2-14), 11 items assessing reduced nicotine content (RNC) cigarette false beliefs (range 14-45), and two items assessing beliefs about additive-free and organic tobacco products. Higher scale scores indicate a higher number of false beliefs.	Wave 4 (weeks 11-13)
Secondary	Intention to Use Nicotine/Tobacco Products	Four items assessing intention to use tobacco cigarettes, e-cigarettes, NRT, and RNC cigarettes during the next 12 months. Adapted from PhenX Toolkit- Susceptibility to Tobacco Products, response options Definitely Yes; Probably Yes; Probably Not; Definitely Not. Outcomes reported for participants reporting Definitely Yes or Probably Yes to each item.	Wave 4 (weeks 11-13)
Secondary	Tobacco Use	Number of days used tobacco in the past 30 days. Days used summed across eight different nicotine/tobacco products (e.g., tobacco cigarettes, e-cigarettes, cigars, NRT, RNC cigarettes).	Wave 4 (weeks 11-13)
