Over two years, eight high schools will be recruited to randomize all 9th grade health classrooms to receive either the 3-session media literacy anti-smoking curriculum or a currently accepted anti-smoking program of equivalent length. This recruitment will occur via two prominent community organizations responsible for anti-tobacco programming in 50 local school districts. Experienced health educators will be trained in implementation of both experimental and control curricula. Outcome measures, demographic data, and other important covariates will be collected by a questionnaire given three times: at baseline, immediately post-intervention, and after one year. Questionnaire items are reliable, valid, and pilot-tested. Process evaluation will be conducted to assess implementation fidelity, to confirm or refute the findings of the quantitative assessment, to help explain outcome data, to refine the intervention, and to inform future replications of the curriculum.
