Abstract
Evidence supports the use of graphic warnings to educate the public about the health harms of smoking and suggests warnings eliciting negative emotional responses may be more effective. This study aimed to replicate a preliminary theory-based model whereby perceived new knowledge promotes discouragement from smoking through its impact on worry about smoking with a different sample and using a new set of cigarette graphic warnings. We explored if the pattern extended to encouragement to use e-cigarettes, and if age and user group moderated the indirect effects of these models. Exclusive smokers, dual/e-cigarette users and nonusers (N = 412) evaluated graphic cigarette warnings on perceived new knowledge and worry about health harms of smoking, discouragement to smoke, and encouragement to use e-cigarettes. Perceived new knowledge was both directly and indirectly associated with discouragement to smoke through worry about health harms of smoking, and did not vary as a function of age or user group. In contrast, perceived new knowledge was not directly or indirectly associated with encouragement to use e-cigarettes, and this pattern largely did not vary as a function of age or user group. Graphic cigarette warnings that enhance knowledge may discourage smoking both directly and indirectly through worry elicited by them, and may have less impact on encouraging e-cigarette use. These findings replicate prior work and generalize to different user groups and new warnings planned for implementation in the U.S.
