The aims of this project are to determine if a theory-driven, school-based, 3-session anti-smoking media literacy curriculum delivered to 9th grade students can affect clinically relevant factors mediating adolescent smoking according to the widely accepted Theory of Reasoned Action: intention to smoke, smoking behavior, attitude toward smoking, and norms involving smoking. It is hypothesized that, compared with those exposed to a currently accepted school-based smoking prevention program, students exposed to the media literacy program will develop more negative attitudes toward smoking, a more negative sense of smoking norms, less intention to smoke, and less smoking. We also expect that the curriculum will improve smoking media literacy scores as measured by a reliable, valid scale.
