Expectancies and mental models as determinants of adolescents' smoking decisions

Cigarette smoking has been identified as the single most preventable source of mortality and morbidity in the United States. Experimentation with tobacco typically begins in adolescence, and smoking during this period is one of the strongest and most consistent predictors of adult smoking status. In the present paper, we review several prominent decision models that have been applied to adolescent smoking, and point out important limitations of these models. We then propose a new process-oriented framework of decision-making based on the concept of mental models, and discuss the implications of this framework for developing effective smoking prevention and cessation interventions for adolescents.
