Effect of sensation seeking on the effect of exposure to movie smoking. The black line reflects the established smoking hazard ratio (risk of becoming an established smoker during the study) as sensation seeking varies. Sensation seeking is scaled so that 0 equals the 5th percentile and 1 equals the 95th percentile for the distribution. The hazard ratio is adjusted for other media variables (movie-viewing venues, movies viewed in the past week, movies viewed with parents), social and other environmental influences (friend smoking, sibling smoking, parent smoking, poor school performance, parental style, extracurricular activities), and characteristics of the adolescent (age, sex, parent education, race, tried smoking at baseline, and rebelliousness).
