The current study employed parallel process and discrete time hazard regressions to examine the interplay among exposure to R-rated movies, sensation seeking, and initiation of alcohol use in a national U.S. sample (N=6255) of adolescents, ages 10-14, who were followed over four waves spanning 2 years. There was a short-term reciprocal relation between watching R-rated movies and sensation seeking, but over the 2-year observation period, exposure to R-rated movies was associated with increases in sensation seeking and not vice versa. Sensation seeking also moderated the effect of watching R-rated movies on initiation of alcohol consumption such that exposure was associated with greater increases in initiation of alcohol use among low sensation than among high sensation seeking adolescents. The study provides empirical evidence of an environmental media effect on sensation seeking, and important new information about the relations among sensation seeking, media exposure, and adolescent alcohol use.

Sensation seeking; Alcohol use; MediaThe emergence of transactional models of development and the statistical methods necessary to test them has generated a more complex and nuanced understanding of the dynamic interplay between a child's personality and the environment (cf., Bronfenbrenner 1995;Collins et al. 2000;Deater-Deckard and Cahill 2006). Three related areas of research have formed the foundation of these new models. First, although previous research and theory conceptualized traits as enduring elements of personality that are stable over time and across situations (Buss and Plomin 1984), contemporary research has demonstrated that traits change in response to environmental influences (Caspi and Moffitt 2001;Johnson et al. 2007). For example, one recent longitudinal analysis of traits revealed that 95% of Correspondence to: James D. Sargent, james.d.sargent@dartmouth.edu.

NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript participants showed reliable change in at least one trait in late adolescence and early adulthood: The modal number of changed traits was three or four (Blonigen et al. 2008). These authors concluded that stability in personality traits can be attributed to genetic influences, whereas changes are largely attributable to environmental influences. Second, a related development is the growing evidence that children vary widely with respect to their reactions to specific environments or environmental events; i.e., environmental influences do not exert uniform effects on all children (Rothbart and Bates 1998;Slater 2007;Tarter and Vanyukov 1999). Third, it has been suggested that the relation between personality and environmental influence is reciprocal; i.e., a child's personality influences his/her preferences for specific environments, and environments can influ...
