National Epidemiologic Survey on Alcohol and Related Conditions (NESARC)—Wave 1 (2001–2002), and Wave 2 (2004–2005)

National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) was designed to assess the prevalence of alcohol use disorders (AUD) and their associated disabilities in the general population. The survey is the largest ever comorbidity study of multiple mental health disorders among U.S. adults, including alcohol and other substance use disorders, personality disorders, and anxiety and mood disorders. NESARC is designed to be a longitudinal survey with the first wave fielded in 2001–2002. The second wave of interviews was completed in 2004–2005 and used the same sample of respondents.

NESARC is a nationwide household survey with a probability sample representative of US adults. The final sample for Wave 1 was 43,093 respondents; Wave 2 was 34,653 of the Wave 1 respondents.

Data are not publicly available; however, researchers may request specific analyses via Census.
