PURPOSE: To assess the effectiveness of a large-scale, national smoking cessation media campaign, the EX campaign, across racial/ethnic and educational subgroups. DESIGN: A longitudinal random-digit-dial panel study conducted prior to and 6 months following the national launch of the campaign. SETTING: The sample was drawn from eight designated media markets in the United States. SUBJECTS: The baseline survey was conducted on 5616 current smokers, aged 18 to 49 years, and 4067 (73% follow-up response rate) were resurveyed at the 6-month follow-up. MEASURES: The primary independent variable is confirmed awareness of the campaign advertising, and the outcome variables are follow-up cessation-related cognitions index score and quit attempts. ANALYSIS: Multivariable logistic and linear regression analyses were conducted within racial/ethnic and educational strata to assess the strength of association between confirmed awareness of campaign advertising and cessation-related outcomes. RESULTS: Confirmed awareness of campaign advertising increased favorable cessation-related cognitions among Hispanics and quit attempts among non-Hispanic blacks, and increased favorable cessation-related cognitions and quit attempts among smokers with less than a high school education. CONCLUSIONS: These results suggest that the EX campaign may be effective in promoting cessation-related cognitions and behaviors among minority and disadvantaged smokers who experience a disproportionate burden of tobacco-related illness and mortality.
