title: Delay discounting by depressed and non-depressed adolescent smokers and non-smokers.
abstract: BACKGROUND
  Both delay discounting and depression are risk factors for cigarette smoking during adolescence. However, very little research has explored associations between these variables in adolescent smokers and non-smokers.
  
  
  METHODS
  Eighty adolescents were recruited based on depression status (depressed and non-depressed) and smoking status (smokers and non-smokers) to form four groups (n=20 per group). All participants completed a computerized monetary delay discounting task and a measure of depression.
  
  
  RESULTS
  Delay discounting and depression were significantly correlated. Also, smokers (both depressed and non-depressed) and depressed non-smokers all discounted significantly more than non-smokers who were not depressed. Depressed non-smokers and both groups of smokers did not differ in rate of delay discounting.
  
  
  CONCLUSIONS
  Adolescent non-smokers who are depressed discount similarly to adolescents who smoke and more than non-smokers who are not depressed. Future research should explore the unique versus shared roles of delay discounting and depression as risk factors for smoking during adolescence.
