Smoking Clinical Trial
Official title:
Messages About Reduced Nicotine in Combusted Tobacco Products: An Online Randomized Controlled Trial
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.
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. In session 2, which will take place 2 weeks after session 1, participants will complete a brief 5-minute survey measuring their recall of the messages and behaviors since message exposure. ;
