IntroductionAlthough awareness of mass-media smoking cessation campaigns is hypothesized to affect quit behavior through changes in cessation-related attitudes, intentions, and motivation (cognitions), this has yet to be formally tested.MethodsStructural equation modeling was used to examine whether changes in cessation-related cognitions mediate the relationship between awareness of a national mass-media smoking cessation campaign, the EX campaign, and quit attempts in a cohort of 3,571 current smokers drawn from eight U.S. Designated Market Areas and followed over an approximate six-month period. Models were examined in the total sample and within racial/ethnic, gender, age, and educational strata.ResultsData suggest that there are both a direct effect of confirmed awareness of EX on quit attempts as well as an indirect effect mediated by positive changes in cessation-related cognitions. Results are not uniform across subgroups; stratified analyses reveal that awareness of EX is significantly associated with positive changes in cessation-related cognitions and quit attempts only in Blacks, males, and those with less than a high-school education.ConclusionsThose developing health communication mass-media campaigns need to consider how media messages might differentially impact U.S. subpopulations in order to elicit desired behavioral change across target subgroups.
