Do Young Adults Perceive That Cigarette Graphic Warnings Provide New Knowledge About the Harms of Smoking?

BACKGROUND: Although much research on graphic cigarette warnings has focused on motivational responses, little focus has been given to how much individuals learn from these labels. PURPOSE: This study aims to investigate whether graphic warnings provide greater perceived new knowledge of smoking consequences compared to text-only warnings, and to test a mediational model whereby perceived new knowledge promotes discouragement from smoking through its impact on worry. METHODS: In two studies, young adult smokers and nonsmokers (ages 18-25) evaluated graphic + text and corresponding text-only labels on perceived knowledge, worry about the harms addressed by the warning, and discouragement from smoking. RESULTS: Compared to text-only labels, graphic + text labels were rated as providing better understanding, more new knowledge, and being more worrisome and discouraging. Perceived new knowledge predicted greater discouragement from smoking directly and through worry. CONCLUSIONS: Graphic warnings may be more efficacious than text-based warnings in increasing knowledge and worry about harms, and discouragement from smoking.
