Summary

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

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.
