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 four 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.

Methods

Universe:

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

Sample:

Multistage area probability sample design involving three election 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. The participation rate among schools has been between 66 and 80 percent since the inception of the study. The student response rates for the 2000 8th- and 10th-grade surveys were 89 percent and 86 percent, respectively.
