  1. Section B ASSIST Evaluation

  2. Measures • Strength of tobacco control index • Index to measure state capacity and infrastructure • Initial outcomes index • Measure of policy change • Media advocacy • Assessed change in newspaper coverage of tobacco policy issue

  3. Measures • Final outcomes • Smoking prevalence (number of people who smoke) • Adults 18+ • Tobacco Use Supplement to the Current Population Survey (TUS-CPS), an NCI-sponsored survey that was part of the U.S. Census Bureau’s Current Population Survey in 1992, 1993, 1998, and 1999 • Per capita cigarette consumption • Calculated every two months for each state • Sales data for the total number of cigarette packs moved from wholesale warehouses, divided by the state’s adult population

  4. What Is the TUS-CPS? http://riskfactor.cancer.gov/studies/tus-cps/ Source: http://riskfactor.cancer.gov/studies/tus-cps/

  5. NCI State Cancer Legislative Database http://www.scld-nci.net/scld_tobaccoratings.cfml Image source: U.S. National Cancer Institute. (2007).

  6. Strength of Tobacco Control Index (SoTC) • SoTC summarizes the multiple components of tobacco control efforts • Provides information on which components of ASSIST or ASSIST-like programs might be related to lower smoking prevalence or cigarette consumption • SoTC is a multi-element measurement • Assesses the effects of three variables in each state: • Tobacco control resources (funding) • Capacity and infrastructure • Program efforts focused on policy and environmental change

  7. SoTC Conceptual Framework

  8. Initial Outcome Index (IOI) • Cigarette price • NCI Cancer Legislative Database • Smoke-free work environment • TUS-CPS • Clean indoor air (CIA) legislative rating • NCI Cancer Legislative Database

  12. Newspaper Tracking System • Content analysis of all daily newspapers in all states (n = 1,767) • Continuous tracking from October 1993 to December 2000 • Selective extraction of tobacco control policy coverage • Clean indoor air • Access to minors • Economic disincentives • Advertising and promotion • Miscellaneous Image source: Daily Freeman. (May 11, 2002).

  13. Variables Collected by the Newspaper Tracking System • Coverage of tobacco issues • Volume • Placement • Type of articles • Slant Image sources: The Palm Beach Post. (May 9, 2002); New York Post. (May 12, 2002).

  15. Overall Challenges for the ASSIST Evaluation • Evaluate NCI non-randomized study and understand tobacco control as conducted within states across the United States • Address the complex, independent, and non-linear forces occurring • Many state-level factors • Test a process for reducing tobacco use on a population-wide level • Multiple experiments are occurring with slightly different approaches in each state

  16. Overall Challenges for the ASSIST Evaluation • Lack of consistent measurement data • Gaps in linking exposures to outcomes • Lack methods to measure quality, fidelity, and rate of implementation • Need better methods to model dynamic hierarchical and time series data

  17. Data Challenges • Limited baseline data • No measure of intervention dose or exposure • Diffusion of intervention strategies to non-ASSIST states; variation between ASSIST states in implementation of interventions • Lack of data to assess tobacco industry’s strength of counter efforts

  18. Framing the Results • “The small but significant differences in the reduction of adult smoking prevalence in ASSIST, when applied on a population basis, could be expected to have a large impact on the public’s health” • “If all 50 states and the District of Columbia had implemented ASSIST, there would have been approximately 1,213,000 fewer smokers nationally” Source: Stillman, F., et al. (2003).

  19. Summary • ASSIST evaluation established the effectiveness of the ASSIST interventions • Lower adult smoking prevalence in ASSIST states • Lower consumption rates in states with higher levels of SoTC, especially related to capacity • Lower prevalence and consumption in states with stronger policies • Results from ASSIST provided evidence that the investment in state tobacco control programs that focused on policy interventions was an effective strategy to reduce tobacco use
