The PASStudy is a Randomized Controlled Trial in which adolescents who smoke cigarettes will be randomized to receive either Motivational Interviewing (MI) or Structured Brief Advice (SBA). MI is an empirically supported, client-centered, directive method for matching counseling to an individual's readiness to change. Based on the principles of motivational psychology, client-centered therapy, and the Transtheoretical Model, MI represents a general and practical approach for changing behaviors by enhancing and facilitating an individual's own internally motivated change process.
