The National Survey on Drug Use and Health (NSDUH)1 is an ongoing cross-sectional face-to-face household survey of approximately 150,000 households and 67,500 persons each year. It collects data through audio computer-assisted self-interviewing (ACASI) and covers the U.S. civilian noninstitutionalized population age 12 and older. Response rates traditionally have been highest among the youngest respondents and lowest among the oldest, with the lowest rates found in the 50 and older (50+) age group. The introduction in 2002 of a series of methodological enhancements to the study appeared to improve the response rates for most age groups but had only a small impact on the 50+ age group (Kennet Gfroerer, Bowman, Martin, & Cunningham, 2003).
