Construction of Smoking-Relevant Risk Perceptions Among College Students: The Influence of Need for Cognition and Message Content.

Changing smokers' health-risk perceptions has been difficult. This study tested whether need for cognition (NC)—a factor within Petty & Cacioppo's (1986) elaboration likelihood model that reflects the preference for effortful cognitive information processing—moderated responses to a smoking risk message intervention. College smokers ( n=227) evaluated a fact-based or emotion-based smoking risk pamphlet or a control pamphlet. Among occasional but not daily smokers, NC interacted as hypothesized with type of message to moderate risk perceptions. Among participants with higher NC, the fact-based message produced the greatest increase in risk perception; whereas among participants with lower NC, the emotion-based message produced the greatest change. Findings demonstrate that individual differences in cognitive processing can influence the potency of health-risk messages. [ABSTRACT FROM AUTHOR]
