high school students,
Date of Collection:
High school seniors in the contiguous United States.
Data Collection Notes:
(1) To protect the privacy of respondents, all
variables that could be used to identify individuals have been
collapsed or recoded in the public use files. These modifications
should not affect analytic uses of the public use files. (2) Variables
omitted from the Western region questionnaires are noted in each
MTF does not release detailed geography codes in its public use files because of the disclosure risk it would cause. The MTF sample is drawn to generate representative samples of the four Census Bureau regions of the country (Northeast, Midwest, South, and West), but it does not generate representative samples of smaller geographic areas such as states, counties, or cities. For additional information about data that is withheld from the public use files please contact MTF directly at firstname.lastname@example.org.
Multistage area probability sample design involving three
selection stages: (1) geographic areas or primary sampling units
(PSUs), (2) schools (or linked groups of schools) within PSUs, and (3)
students within sampled schools. Of the 80 PSUs, 8 were selected with
certainty and 72 were selected with probability proportionate to size
based on the size of the senior class. In schools with more than 400
seniors, a random sample of seniors or classes was drawn. In schools
with less than 400 seniors, all seniors were asked to participate.
Each school was asked to participate for two years so that each year
one-half of the sample is replaced. Schools refusing participation
were replaced with similar schools in terms of geographic location,
size, and type of school (e.g., public, private/Catholic,
private/non-Catholic). The total sample was divided into six
subsamples consisting of an average of 2,700 respondents, and each
subsample was administered a different form of the questionnaire,
although all respondents answered the "core" drug and demographic
questions. The participation rate among schools has been between 66
and 85 percent since the inception of the study. The overall student
response rate for 2000 was 83 percent.
Mode of Data Collection:
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:
Standardized missing values.
Created online analysis version with question text.
Performed recodes and/or calculated derived variables.
Checked for undocumented or out-of-range codes.
