The expected outcomes of drug use figure prominently in models of drug motivation. This report presents the relations between self-generated expected outcomes of smoking and smoking behavior in 674 adolescents. Expected outcomes of smoking were related to current smoking, experimentation, and susceptibility among never-smokers, even after controlling for key correlates of smoking behavior, including gender, grade, ethnicity, and peer smoking. Although more negative than positive smoking outcomes were accessible from memory, more positive than negative expected outcomes were correlated with smoking behavior. Both the content and number of self-generated expected outcomes provided unique associative information. In sum, greater elaboration of smoking-related memory networks, as well as the specific content of those networks, appear to be associated with smoking behavior.
