Unit of Observation:
The noninstitutionalized civilian population of the United
States, aged 12 and older.
Data Collection Notes:
Data were collected by Research Triangle
Institute, Research Triangle Park, NC, and prepared for release by
National Opinion Research Center, Chicago, IL.
variables, statistical imputation was performed following logical
imputation to replace missing responses. Unique code values (7, 8, or
9) were assigned to the recency-of-use variable when such logical
imputation occurred. These code values are readily identifiable by the
phrase "... LOGICALLY IMPUTED" in the code value descriptions. For
those recency-of-use variables with missing data for which no
indication of use of the drug could be found by examination of all
relevant variables in the record, a code value of 91 ("Never Used")
was assigned if there were one or more indications of such nonuse in
the set of relevant variables.
To protect the anonymity of respondents, all
variables that could be used to identify individuals have been deleted
from the public use file.
For some drugs that have multiple names, questions regarding the use of that drug may be asked for each distinct name. For example, even though methamphetamine, methedrine and desoxyn are the same drug, their use was measured in three separate variables.
Multistage area sample design with oversampling of six
Metropolitan Statistical Areas of special interest: Washington, DC,
New York City, Miami, Chicago, Denver, and Los Angeles. Minorities and
youths aged 12-17 were also oversampled.
Data were weighted based on the
three stages of sampling that were used. Adjustments were made to compensate for nonresponse and
sampling error. Adjustments also included trimming sample weights to
reduce excessive weight variation and a post-stratification to Census
population estimates. The final weight variable to be used in analysis is ANALWT.
personal interviews, including self-enumerated answer
sheets for questions on drugs
Strategies for ensuring high rates of participation resulted in
an interview response rate of 84.2 percent. Of the 32,594 completed
interviews, 16,628 were with Whites and other (i.e., non-Hispanic,
non-Blacks), 8,050 were with (non-Hispanic) Blacks, and 7,916 were
with Hispanics. Approximately 7 percent (2,190) of the interviews were
conducted using the Spanish version of the questionnaire. The
completed interviews represented a 96.5 percent completion rate for
screening sample households and an 84.2 percent for interviewing sample
individuals. The response rates for these three racial/ethnic groups
were 82.3 percent for Whites and others, 85.1 percent for Blacks, and 87.3 percent for
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
Performed consistency checks.
Standardized missing values.
Created online analysis version with question text.
Checked for undocumented or out-of-range codes.
Restrictions: Users are reminded by the United States Department of Health and Human Services that these data are to be used solely for statistical analysis and reporting of aggregated information and not for the investigation of specific individuals or treatment facilities.
