Abstract:

The BRFSS is an RDD telephone survey conducted by state and territorial health departments and sponsored by the Centers for Disease Control. Sample and questionnaire design are similar in all states in any year. In recent years, the number of respondents has been about 2,000--6,000, totaling 200,000--300,000 from all states. The BRFSS reports several indicators of the quality of survey execution for each state, including cooperation rates, response rates, and call disposition codes. A public-use data file includes item-specific missing data codes for refused and don't know/not sure. Respondents who complete partial surveys may be identified from the data. Variation among the indicators of survey quality exceeds chance across states and years and is identified with both state and personal characteristics that relate to survey quality.
