Adolescent psychological and social predictors of young adult smoking acquisition and cessation: A 10-year longitudinal study.

Objective: A 10-year follow-up study to test the extent to which theory-based adolescent psychological and social factors directly predict and moderate the prediction of young adult smoking acquisition and cessation.
