title: Differential effects of depression on smoking cessation in a diverse sample of smokers in treatment.
abstract: BACKGROUND
  Recent cross-sectional evidence suggests that the effect of depression on smoking prevalence and quit ratios differs by race/ethnicity.
  
  
  OBJECTIVE
  This study prospectively examined the main and interactive effects of race/ethnicity and depressive symptoms on smoking cessation during a specific quit attempt among smokers receiving cessation treatment.
  
  
  METHODS
  Data from a longitudinal study of smokers in treatment were examined using continuation ratio logit modeling. Continuous abstinence across Weeks 1, 2, and 4 post-quit was the outcome variable. Data were collected between March 2005 and November 2007, and the current study analyses were conducted in April 2010.
  
  
  RESULTS
  Depressive symptoms predicted significantly lower cessation rates for whites and African Americans. In contrast, among Latinos there was no relationship between depression and cessation.
  
  
  CONCLUSIONS
  This research is the first to prospectively demonstrate a racially/ethnically differentiated effect of depressive symptoms on smoking cessation, and it has implications for targeted smoking-cessation treatments as it indicates that depression may not be a key treatment target for Latinos.
