Evaluating the Validity of the BRFSS Disability Screening Questions

Categorized Under: Business Process Operations + Optimization, Surveys



ICF International helped the Centers for Disease Control and Prevention (CDC) evaluate Behavioral Risk Factor Surveillance System (BRFSS) survey questions 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; provided extensive analysis of existing data, sensitive cognitive interviewing, and detailed comparison of disability questions for a variety of established survey instruments; and developed and tested new questions through a telephone survey. After data collection, ICF conducted analyses to evaluate the test–retest reliability and the validity of the BRFSS and other disability questions.

The results helped the CDC and other agencies streamline the questions used on public surveillance surveys—a Healthy People 2020 Goal.
