Enhancing Source Credibility in Tobacco Regulatory Communications

Summary

This study will assess the impact of cigarette constituent messages with and without FDA source and quit information in a randomized controlled trial. The investigators hypothesize that cigarette constituent messages will increase intention to quit compared to messages about littering cigarettes (the control). The investigators also hypothesize that constituent messages that include FDA source and quit information will increase intention to quit compared to messages without that information.

Conditions

• Cigarette Smoking Behavior

Interventions

BEHAVIORAL

Constituent message with FDA and quitline

Messages about the chemical constituents of cigarette smoke will include text about chemicals in cigarette smoke and health effects of the chemicals, and an image of a person related to the health effect. This arm will also include an FDA logo, and information about the benefits of quitting smoking and the quitline. Each condition has 5 messages that will be repeated 3 times in a counterbalanced order. Study investigators used text developed by investigators associated with our Center for Regulatory Research on Tobacco Communication. Design of these messages was developed by our team.

BEHAVIORAL

Constituent message without FDA and quitline

Messages about the chemical constituents of cigarette smoke will include text about chemicals in cigarette smoke and health effects of the chemicals, and an image of a person related to the health effect. This arm is identical to the arm above, except that it does not include FDA source or quit information. Each condition has 5 messages that will be repeated 3 times in a counterbalanced order. Study investigators used text developed by investigators associated with our Center for Regulatory Research on Tobacco Communication. Design of these messages was developed by our team.

BEHAVIORAL

Littering message (Control)

Messages about littering cigarettes will include text designed to discourage people from littering their cigarette butts, and an image related to the message. Each condition has 5 messages that will be repeated 3 times in a counterbalanced order. Study investigators used text developed by investigators associated with our Center for Regulatory Research on Tobacco Communication. Design of these messages was developed by our team.
