Colorado Tobacco Attitudes and Behaviors Survey (COTABS)

At the height of tobacco culture in America, marketers led massively influential campaigns to introduce tobacco products into every household. ICF conducts research to identify the most widespread, influential and changeable risk factors to reverse harmful behaviors, such as tobacco use.

The Tobacco Attitudes and Behaviors Surveys (TABS) collects information from people 18 years of age and older who speak English or Spanish and reside in a household with a telephone or possess a cell phone. In 2008, ICF conducted over 14,000 phone interviews in Colorado to collect detailed information about individual, community, social, and environmental factors. In 2012, ICF collected 15,000 surveys in Colorado and over 3,000 nationally. For the Colorado surveys, we stratified the sample based on county and 21 Health Statistical Regions, and oversampled African Americans and Hispanic respondents. For both Colorado and the national sample, TABS was based on a dual-frame sampling design including:

  • A two-stage stratified, list-assisted, random digit dialing (RDD) sample of adults in landline telephone households
  • A stratified RDD sample of cell phone users

To target completions with minorities in Colorado, we identified Arapahoe and Denver as counties with disproportionately larger African American and Hispanic populations. To further augment the sample yields for African Americans, ICF used cell samples matched to ZIP codes to oversample areas with high densities of African American households.

ICF provided the University of Colorado, Denver Cancer Center with sophisticated data needed to paint a more detailed picture of Colorado residents’ public health characteristics.
