简要总结
Tobacco use is the leading preventable cause of cancer and cancer deaths in the US. While most (69%) smokers want to quit, only 6% succeed in doing so each year. For many smokers, the addictiveness of nicotine makes quitting very difficult. To reduce cigarette smoking and resulting harms, FDA has announced a comprehensive approach to tobacco and nicotine regulation that includes moving toward a very low nicotine content (VLNC) standard for cigarettes. Greatly reduced nicotine levels would facilitate smoking cessation. However, the maximal success of the policy may require public understanding that, although these new cigarettes are less addictive, their high toxicity and carcinogenicity are unchanged. Yet, nearly half of adult smokers incorrectly think smoking VLNC cigarettes is less harmful than smoking current cigarettes (the VLNC misperception). Additionally, 24% of smokers said they would be less likely to quit if a VLNC regulation is enacted. Thus, the VLNC misperception may partially undermine a nicotine reduction policy. Although communication research suggests it is challenging to change people's incorrect understanding, new communication techniques may help reduce the VLNC misperception. In this randomized trial we will examine whether messages about the harm of VLNC cigarettes can reduce the VLNC misperception and increase intention to quit in a nicotine reduction scenario.
详细描述
In this study we will assess whether messages about the harm of VLNC cigarettes reduce the misperception that they are less harmful than regular cigarettes.
Recruitment:
We will enroll participants from an existing nationally representative panel.
Informed Consent:
Potential participants are part of an existing nationally representative panel and have already consented to participate in the panel. Before enrolling, participants will also be asked to consent to participate in this study via a consent form included in the study survey.

结局指标
主要结局
Percentage of Participants With Very Low Nicotine Content (VLNC) Misperception About Harm (Dichotomized)
时间窗: During one day survey
Very low nicotine content (VLNC) Misperception of Harm was measured with 1 question, on a scale of 1 to 5, where 1 indicates a perception that VLNC are much more harmful than other cigarettes, and 5 indicates a perception that VLNC are much less harmful than other cigarettes, and 3 is a perception that VLNC are as harmful as other cigarettes. The results were dichotomized to indicate the percentage of people who hold the misperception. Specifically, responses of "much less likely" (5) or "less likely" (4) were recoded as 1 (having the misperception), and responses of "Much more likely" (1), "More likely" (2), or "As likely" (3) were recoded as 0 (not having the misperception).
Percentage of Participants With Very Low Nicotine Content (VLNC) Misperception About Cancer (Dichotomized)
时间窗: During one day survey
Very low nicotine content (VLNC) Misperception of Risk of Cancer was measured with 1 question, on a scale of 1 to 5, where 1 indicates a perception that VLNC are much more likely to cause cancer than other cigarettes, and 5 indicates a perception that VLNC are much less likely to cause cancer than other cigarettes, and 3 is a perception that VLNC are as likely to cause cancer as other cigarettes. The results were dichotomized to indicate the percentage of people who hold the misperception. Specifically, responses of "much less likely" (5) or "less likely" (4) were recoded as 1 (having the misperception), and responses of "Much more likely" (1), "More likely" (2), or "As likely" (3) were recoded as 0 (not having the misperception).
Very Low Nicotine Content (VLNC) Misperception
时间窗: During one day survey
Measured by a 3 item scale. Very low nicotine content (VLNC) Misperception measured with 3 questions, the final VLNC misperception score is a mean of the response to the 3 questions, on a scale of 1 to 5, where 1 indicates a perception that VLNC are much more harmful than other cigarettes, and 5 indicates a perception that VLNC are much less harmful than other cigarettes, and 3 is a perception that VLNC are as harmful as other cigarettes.
Percentage of Participants With Very Low Nicotine Content (VLNC) Misperception About Death (Dichotomized)
时间窗: During one day survey
Very low nicotine content (VLNC) Misperception of Risk of Death was measured with 1 question, on a scale of 1 to 5, where 1 indicates a perception that VLNC are much more likely to cause death than other cigarettes, and 5 indicates a perception that VLNC are much less likely to cause death than other cigarettes, and 3 is a perception that VLNC are as likely to cause death as other cigarettes. The results were dichotomized to indicate the percentage of people who hold the misperception. Specifically, responses of "much less likely" (5) or "less likely" (4) were recoded as 1 (having the misperception), and responses of "Much more likely" (1), "More likely" (2), or "As likely" (3) were recoded as 0 (not having the misperception).
