Core Components of Survey

The BRFSS survey is composed of three main sections:

  • Core Component
  • Optional Module
  • State-Added Questions

All states must ask the core component questions without modification.

States may choose to add any, all, or none of the optional modules and state-added questions after asking the core component questions.

Behavioral Risk Factor Surveillance System (BRFSS)

Nearly year-round, the South Carolina Department of Public Health (DPH) participates in the Behavioral Risk Factor Surveillance System (BRFSS) — the world's largest continuously conducted health survey system in the world. The BRFSS is a random telephone survey of non-institutionalized individuals aged 18 or older that is used to track health risks, behaviors and preventative health practices in the United States.
