The NHSDA is anjannual survey of the civilian noninstitutionalized population of the United States, 12 years old or older.sIn 1999, the NHSDA underwent a major redesign. The method of data collection was changed from a paper questionnaireadministration to a computer-assisted administration. In addition, the sample design was changed from a strictly national designvto a state-based sampling plan. These important changes to the NHSDA have a major impact on the data that are producedzfrom the survey. The expanded sample makes it possible to produce, each year, substance use prevalence estimates for every~state and the District of Columbia. It also allows more detailed analyses of national patterns of use. However, because of thexdifferences in methodology and impact of the new design on data collection, only limited comparisons can be made betweensdata from the redesigned surveys (1999 onward) and data obtained from surveys prior to 1999. Therefore, this reportzaddresses primarily the changes in rates of use between 1999 and 2000 and the differences in patterns of use among various<demographic and geographic subgroups of the U.S. population.!1.1. Summary of NHSDA MethodologywThe NHSDA is the primary source of statistical information on the use of illegal drugs by the United States population.|Conducted by the Federal Government since 1971, the survey collects data by administering questionnaires to a representative~sample of the population through face-to-face interviews at their place of residence. The survey is sponsored by the SubstanceqAbuse and Mental Health Services Administration (SAMHSA), and data collection is carried out by Research TriangleInstitute. The project is planned and managed by the Office of Applied Studies. This section contains a brief description of theJsurvey methodology. A more complete description is provided in Appendix A.}The NHSDA collects information from residents of households, noninstitutional group quarters (e.g., shelters, rooming houses,zdormitories), and civilians living on military bases. Persons excluded from the survey include the homeless who do not use{shelters, active military personnel, and residents of institutional group quarters, such as jails and hospitals. Appendix CWdescribes surveys that cover populations that are not part of the NHSDA sampling frame.sPrior to 1999, the NHSDA was conducted as a paper-and-pencil interview (PAPI) lasting about an hour. The NHSDA PAPIinstrumentation consisted of a questionnaire booklet that was completed by the interviewer and a set of individual answer sheetswthat were completed by the respondent. All substance use questions and other sensitive questions appeared on the answerxsheets so that the interviewer was not aware of the respondent's answers. Less sensitive questions such as demographics,yoccupational status, household size and composition were asked aloud by the interviewer and recorded in the questionnairebooklet.rBeginning in 1999 the NHSDA interview has been carried out by computer-assisted interview (CAI). The survey uses avcombination of computer-assisted personal interview (CAPI) conducted by the interviewer and an audio computer-assisted{self-interview (ACASI). For the most part, questions previously administered by the interviewer are now administered by thevinterviewer using CAPI. Questions previously administered using answer sheets are now administered using ACASI. Use ofzACASI is designed to provide the respondent with a highly private and confidential means of responding to questions and toYincrease the level of honest reporting of illicit drug use and other sensitive behaviors.qConsistent with the 1999 NHSDA, the 2000 NHSDA sample employed a 50-state design with an independent, multi-stage|area probability sample for each of the 50 States and the District of Columbia. The eight states with the largest population}(which together account for 48 percent of the total U.S. population aged 12 and older) were designated as large sample statesz(California, Florida, Illinois, Michigan, New York, Ohio, Pennsylvania and Texas). For these states, the design provided a}sample large enough to support direct state estimates. For the remaining 42 states and the District of Columbia, smaller, butxadequate, samples were selected to support state estimates using small area estimation (SAE) techniques. The design also|oversampled youths and young adults, so that each state's sample was approximately equally distributed among three major agezgroups: 12 to 17 years, 18 to 25 years, and 26 years and older. To enhance the precision of trend measurement, half of thezfirst-stage sampling units (area segments) in the 1999 sample were also in the 2000 sample. However, all of the households%included in the 2000 sample were new.wNationally, 169,769 addresses were screened for the 2000 survey and 71,764 persons were interviewed within the screenednaddresses. The survey was conducted from January through December, 2000. Weighted response rates for householdPscreening and for interviewing were 92.8 percent and 73.9 percent, respectively.
