Anxiety and Depression Optional Module—Behavioral Risk Factor Surveillance System (BRFSS)
The BRFSS is an annual state-based telephone survey of the U.S. civilian, non-institutionalized adult population. The core questionnaire contains questions asked of all respondents, while states may choose to also include optional modules addressing various topics. The optional Anxiety and Depression Module assesses the prevalence of anxiety and depressive disorders in the general population at the state level. This module is composed of the Patient Health Questionnaire (PHQ-8) which has been validated against the nine diagnostic criteria for a depressive disorder in the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV).
