Health Communications for Adults Smoking Nondaily

The goal of this study is to develop smoking health risk messaging targeted to adults who smoke some days, but not smoke every day (nondaily). The main purpose is to learn what type of smoking health risk messages will be most likely to encourage adults nondaily to quit completely. Aim 1will iteratively obtain qualitative feedback from adults smoking nondaily on initial message designs, resulting in 12 final messages. Aim 2 will test message properties using a 2 (health vs. social messages) x 2 (positive vs. negative messages) between subjects design to ascertain which messages promote proximal outcomes associated with quitting cigarettes (e.g., new knowledge, risk perceptions, motivation and intentions to quit).
