The present work was conducted using data from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC). The NESARC was designed and supervised by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and conducted by the U.S. Census Bureau Field Representatives from 2001-2002 (Wave 1) (Grant et al., 2004a). NESARC is considered to be a nationally representative sample of the non-institutionalized adult population in the United States, with 43,093 respondents in total. The NESARC sample was first weighted and then adjusted to be representative of the U.S. population for multiple socio-demographic variables, including: region of the country, gender, age, race, and ethnicity. More details on the NESARC’s complex sampling design and methodology, as well as the informed consent process, are available in the Source and Accuracy Statement for Wave 1 of the 2001-2002 NESARC (Grant et al., 2003a).
