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, or for numeric risks (e.g., percentage risk for developing lung cancer). This trial tests memory for numeric health risks immediately or after a six-week delay for US adult smokers. In addition, the trial tests the effects of different warning label components (e.g., whether the numeric risks are percentage or frequency), participants' level of numeric ability, and the consequences of memory for numeric risks on participant risk perceptions and quit intentions.
