Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main purpose of this trial is to identify effective quit smoking ads for people who smoke menthol cigarettes. Investigators will conduct an online randomized trial with a nationally representative sample of \~1,400 US adults (ages 21+) who smoke menthol cigarettes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This trial will evaluate the effectiveness of efficacy-based quit smoking ads in a 5 (theme) x 6 (ad) mixed factorial randomized design.

Recruitment: A survey company will recruit \~1,400 participants. Participants will complete a screener to confirm that they are US adults (ages 21+), currently smoke menthol cigarettes, and are able to read and speak English. A portion of the sample will be nationally representative, and a portion will be a convenience sample.

Informed Consent: The consent form will appear on the first page of the survey. Participants will provide their consent to be in the trial by clicking on a button that forwards to the next page of the survey.

Randomization: After consent, the survey software will randomize participants to 1 of 5 themes between-subjects. The design will include 3 intervention ad themes about quitting smoking (self-efficacy ads, response efficacy ads, or motivation ads) and 2 control ad themes about neutral non-smoking related topics (reading or password safety).

Each participant will view 6 ads on their assigned theme, presented in a random order.

Assessment: Participants will complete a \~15 minute online survey one time.
