Messages About Reduced Nicotine in Combusted Tobacco Products: An Online RCT
Study Details
Study Description
Brief Summary
We 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.

Detailed Description
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.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Reduced Nicotine Messages Participants will receive messages with information about reduced nicotine cigarettes. |
Behavioral: Reduced nicotine message exposure
Participants will be shown two messages about harms of reduced nicotine cigarettes. The two messages will be drawn from a pool of five messages. The messages will communicate that reduced nicotine cigarettes will still have the rest of the harmful chemicals and cause diseases as the regular cigarettes, but they would make it easier to quit.
|
Experimental: Modified Risk Messages Participants will receive messages with information about e-cigarettes. |
Behavioral: Modified risk message exposure
Participants will be shown two messages about electronic cigarettes as an alternative to regular cigarettes. The two messages will be drawn from a pool of five messages. The messages will communicate that electronic cigarettes are less likely than regular cigarettes to cause severe diseases such as lung cancer.
|
Experimental: Combined Message -- Reduced Nicotine + Modified Risk Exposure Participants will receive messages about reduced nicotine cigarettes and about e-cigarettes. |
Behavioral: Combined message exposure (reduced nicotine + modified risk)
Participants will be shown two messages, one from the reduced nicotine message set and one modified risk message set.
|
Other: Control Participants will receive messages about bottled water which should have no impact on the outcomes of interest. |
Behavioral: Control message exposure
Participants will be shown two messages about drinking bottled water. These will be selected from a pool of five message. The messages display specific water products and describe hydration as a healthy activity.
