Pictorial cigarette warning labels (PWLs) are thought to increase risk knowledge, but experimental research has not examined PWLs' longer term effects on memory for health risks. In this study, teens who have experimented with smoking or are considered vulnerable to smoking are repeatedly exposed to text-only vs. graphic warning labels paired with numeric risk information. This study will allow us to assess the extent to which reactions to warnings remain consistent over time and influence future smoking intentions. We will also assess the impact of graphic images on memory for smoking risk information presented in absolute and (a smokers lifetime risk of getting a smoking related disease), or relative (a smokers risk of getting a smoking related disease, compared to the risk of non-smokers) formats.

Participants answered one multiple choice question about the numeric risk for smokers vs. nonsmokers for each health risk (e.g., a smoker is ____ as likely to die from heart disease as a nonsmoker). For each question, there were three decoy responses (e.g., for heart disease, response options were: "about as likely," "1.75 times," "4.1 times," "10.4 times"). |
