Delaware BRFS: Changing To Meet New Challenges

Technological and cultural changes are posing significant challenges to telephone survey research. One of the most significant challenges has been the rapid increase in households in which telephone service is primarily or only by cell phones.

Starting with reporting of our 2011 data, the BRFS has become a multi-mode survey, including landline telephone and cell phone interviews.The BRFS is now also using a new method for weighting data that more accurately reflects the actual population of each state.

The 2011 data will break trend lines and become a new baseline for future analyses. The end result will be improved scientific validity of BRFS data. These improvements will ensure that the BRFSS continues to be the leading source of essential behavioral data for public health planning, program development, education, and evaluation.
