Evaluating the Validity of the BRFSS Disability Screening Questions

Categorized Under: Business Process Operations + Optimization, Surveys

 

 

The CDC enlisted ICF’s help to evaluate survey questions in the nationwide Behavioral Risk Factor Surveillance System (BRFSS) that are designed to identify people with disabilities.

Researchers and policy-makers make heavy use of the data collected from BRFSS to determine what the ideal question set would measure. ICF defined disability for the BRFSS measurement; analyzed existing data to determine what sorts of people are, and are not, identified by different disability question sets currently in use on other surveys; and developed and tested new questions through a telephone survey. The telephone survey included landline and cell phone users in baseline and follow-up interviews.

After data collection, ICF conducted analyses to evaluate the test-retest reliability and the validity of the BRFSS and other disability questions.
