The Healthy People 2010 Objectives address the importance of smoking cessation during pregnancy and the importance of reducing ETS exposure among children and adults. This study will use a new combination of existing technologies to maximize the appropriateness of prenatal and postpartum education concerning ETS exposure in an innovative, inexpensive, and widely applicable approach. The use of tailored DVDs is practical, feasible, and inexpensive enough to be attractive to clinics serving low-income and minority women. A large number of video segments will be produced utilizing live actors, animation, and word slates. About 10 segments will be computer-selected for the videos for each woman based on her responses to four self-assessments. No studies to date have included multiple doses of tailored video education, or used DVDs in this way.
