Sociodemographic and attitudinal correlates of alcohol and other drug use among children and adolescents: analysis of a large-scale attitude tracking study.

Data from the Partnership Attitude Tracking Study are analyzed to provide a greater understanding of the contributing factors to alcohol and other drug use among children and adolescents. The data were collected from children (ages 9 to 12) and teenagers (ages 13 to 17) in central locations (usually shopping malls) located in 100 primary sampling units across the United States. The analysis, which primarily employed stepwise multiple regression for model estimation, reinforced the importance of friends use, perceived risk, and tobacco and alcohol use in predicting marijuana use. An exposure model, which included antidrug advertisements, was a particularly powerful model. Implications of the findings are discussed.
