Brief Summary

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, adult smokers are repeatedly exposed to text-only vs. low arousal graphic vs. high arousal graphic warning labels paired with numeric risk information. This study will allow the investigators to assess the extent to which reactions to warnings remain consistent over time and influence smoking risk perceptions and quit intentions. The investigators will also assess the impact of graphic images on memory for smoking risk information presented in absolute (a smoker's lifetime risk of getting a smoking related disease) versus relative (a smoker's risk of getting a smoking related disease, compared to the risk of non-smokers) formats.

Conditions

Smoking Cessation; Smoking, Cigarette

Keywords

pictorial warning labels; risk knowledge; emotion; memory; risk perceptions; quit intentions

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (13)

• numeric risk recognition

  measured after 6-week delay

• relative risk recognition

  measured immediately following last exposure

• relative risk recognition

  measured after 6-week delay

• smoking risk perceptions

  measured immediately following last exposure

• smoking risk perceptions

  measured after 6-week delay
