title: Using a cessation-related outcome index to assess California's cessation progress at the population level.
abstract: BACKGROUND
  The California Tobacco Control Program (CTCP) has employed strategies to change social norms around smoking in order to decrease the prevalence of smoking and tobacco-related diseases. Research is scarce on CTCP's impact on overall smoking cessation in California.
  
  
  METHODS
  Tobacco Use Supplement to the Current Population Survey (TUS-CPS) data from 1992-1993 to 2006-2007 was used to create a cessation-related outcome index (CROI), which was a summarised z score of the following determinants: plan to quit, quit attempt and recent quit rate for each of the 50 US states. CROI trends over the period of six separate TUS-CPSs were plotted for California and other comparison states, for 18-34 year olds and for those 35 years or older separately in the context of historical cigarette price z score trend.
  
  
  RESULTS
  California had a consistently high CROI for both age groups. The CROI trend line increased moderately in California for both age groups despite a declining cigarette price z score trend. In contrast, other selected states with a declining cigarette price z score trend had a declining CROI trend for both age groups.
  
  
  CONCLUSIONS
  The increase of CROI in California while cigarette price z score trend declined suggests that the implementation of CTCP, even without a significant direct cessation component, has had a profound impact on cessation outcomes.
