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.

Primary | numeric risk recognition | Participants answered one multiple choice question about the numeric risk for smokers for each label (e.g., ____% of smokers die before age 85). For each question, there were four decoy responses. | measured immediately following last exposure | |
Secondary | numeric risk recognition | Participants answered one multiple choice question about the numeric risk for smokers for each label (e.g., ____% of smokers die before age 85). For each question, there were four decoy responses. | measured after 6-week delay | |
Secondary | relative risk recognition | 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"). | measured immediately following last exposure | |

Secondary | smoking risk perceptions | Participants completed several scale items about how much risk they perceived smoking posed to them (e.g., "If a person smokes at your age, how likely are they to get a life-threatening illness from smoking someday ?" [1=very unlikely; 5=extremely likely]) | measured immediately following last exposure | |

Secondary | quit intentions (for next 30 days) | Participants intentions to quit smoking; self-reported likelihood of smoking "within the next 30 days" (-3 = very unlikely, 3 = very likely) (only for those teens who currently smoked) |

Secondary | feelings about smoking | Participants completed several scale items about their feelings towards smoking (e.g., "How good or bad do you feel about smoking?" -2=very bad; +2=very good; "How much do you feel confused about the harms vs. benefits of smoking?" 0=not at all confused; 4=very confused) | measured immediately following last exposure | |
