| Summary: | These surveys of 8th- and 10th-grade students are part of a
series that explores changes in important values, behaviors, and
lifestyle orientations of contemporary American youth. Students in
each grade are randomly assigned to complete one of two
questionnaires, each with a different subset of topical questions but
containing a set of "core" questions on demographics and drug
use. There are about 300 variables across the questionnaires. Drugs
covered by this survey include amphetamines (stimulants), barbiturates
(tranquilizers), other prescription drugs, tobacco, alcohol,
inhalants, steroids, marijuana, hashish, LSD, hallucinogens, cocaine,
crack, and injection drugs such as heroin. |

| Universe: | Enrolled 8th- and 10th-grade students in the contiguous
United States. |

| Data Collection Notes: | To protect the anonymity 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. |

|
| Sample: | 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. Separate samples were drawn for each
grade. Of the 80 PSUs, 8 were selected with certainty and 72 were
selected with probability proportionate to size based on the size of
the 8th- (or 10th-) grade class in each school. In schools with more
than 400 8th (or 10th) graders, a random sample of students or classes
was drawn. In schools with less than 400 8th (or 10th) graders, all
students were asked to participate. Each sampled 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). For the
8th-grade survey, schools with less than 15 8th graders were excluded
from the sample. For the 10th-grade survey, schools with less than 25
10th graders were excluded. |

| Weight: | Each of the seven parts contains a weight variable, V5. They
were originally varied by school but were modified to protect
respondent confidentiality. Users should use the weight variable for
all analyses, the results of which will differ slightly from published
data tables that used original data. |
|---|
| |
| Mode of Data Collection: | self-administered questionnaires |
|---|
| |
| Response Rates: | The participation rate among schools has
been between 66 and 80 percent since the inception of the study. The
student response rates for the 1998 8th- and 10th-grade surveys were
88 percent and 87 percent, respectively. |
