简要总结
The investigators will conduct a message-exposure experiment with nationally representative samples of smokers, dual-users (cigarettes and e-cigarettes), and young adult non-smokers (aged 18-29).
Experimental messages will address the reduction of nicotine in cigarettes. Participants will also complete a follow-up survey after 2 weeks, measuring their recall of the messages and behaviors since message exposure.
详细描述
A national probability-based sample will be recruited to include 900 current exclusive smokers, 450 dual users, and 450 young adult (18-29) non-smokers, evenly split between men and women.
The study will be conducted using a self-administered, online questionnaire via proprietary, web-assisted interviewing software.
Participants are randomized to one of four conditions:
- reduced nicotine messages
- modified risk messages
- a combination of reduced nicotine message and modified risk message
- control messages with no cigarette-related content
Participants will take part in two sessions: in session 1 (estimated at about 15 min) participants will see the messages and report immediate outcomes including risk perceptions.

结局指标
主要结局
Perceived Health Risk of VLNCs (Absolute)
时间窗: Immediately after exposure
Measured with a single item, assesses participant's perception of own risk of overall harm to health under conditions of smoking reduced nicotine cigarettes every day. Response options range from 1 (Not at all likely) to 5 (Extremely likely), with higher scores representing a better outcome. An additional option, "Don't know", is also provided.
次要结局
