Data from Wave 1 and Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were analyzed in this study (Grant et al. 2007). NESARC used a complex survey design to yield population-representative estimates of United States adults living in noninstitutionalized settings in 2000. Interviews for Wave 2 were conducted from 2004-2005 and included 34,653 respondents, reflecting an 86.7% follow-up rate among Wave 1 participants who were eligible for re-interview. Response at Wave 2 was not associated with age, race/ethnicity, gender, socioeconomic status, or lifetime AUD (Grant et al. 2009). The methodology and participants of NESARC have been described in prior studies (Grant et al. 2004; Grant et al. 2009).
