This study was approved by the University of Delaware's IRB. Data were drawn from a community sample of adolescents and their parents. Survey data were collected from seven public high schools in the Mid-Atlantic United States by trained research staff in schools. Parent consent forms were mailed to parents prior to data collection. Parents who did not wish to have their adolescent participate were asked to contact the research project staff. Adolescents were asked to sign assent forms prior to participation. Participants were told that their information would be kept confidential and they could withdraw from the study at any time. The survey took approximately 40 minutes to complete and adolescents were compensated for their time with a movie pass.
