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. This trial tests memory for health risks immediately or after a six-week delay for US-representative adult smokers, US-representative teen smokers/vulnerable smokers, and Appalachian-representative adult smokers. In addition, the trial tests the effects of different warning label components and the consequences of memory for labels on risk perceptions and quit intentions.

Conditions

Smoking Cessation; Smoking, Cigarette

Keywords

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

Outcome Measures

Primary Outcomes (2)

• graphic warning label recall

  free recall for risk information presented in labels (9 text boxes, 1 for each label; coded for exact or equivalent words)

  immediately following last exposure or after 6-week delay

• smoking risk recognition

  Participants were subsequently shown twenty-six negative health effects and asked "Which of the following health effects were mentioned in the warnings we showed you?" and responded "Yes, I saw this health effect" or "No, I did not see this health effect." Fourteen risks were mentioned in the warnings (e.g., cancer, harms children, emphysema); six were risks of smoking not presented in the warnings (e.g., wrinkles, diabetes), and six were not risks of smoking (e.g., acne, thyroid problems).

  immediately following last exposure or after 6-week delay

Secondary Outcomes (2)

• smoking risk perceptions

  immediately following last exposure or after 6-week delay

• quit intentions

  immediately following last exposure or after 6-week delay
