The Pennsylvania Adolescent Smoking Study (PASStudy) will evaluate the effectiveness of Motivational Interviewing (MI) compared to Structured Brief Advice (SBA) to reduce cigarette smoking among adolescents who smoke. MI is a brief 5 session client-centered psychotherapeutic style intended to increase "the probability that a person will enter into, continue and adhere to a specific change strategy." This will be compared with SBA, which implements Best Practice Guidelines (i.e., 5 A's and 5 R's) and assists participants in accessing the best available resources for smoking cessation.
