Monitoring the Future (MTF) Series

Scope of Study

This is the 26th annual survey in this series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students are randomly assigned to complete one of six questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and drug use. There are about 1,400 variables across the questionnaires. Drugs covered by this survey include tobacco, alcohol, marijuana, hashish, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), quaaludes, barbiturates (tranquilizers), cocaine, crack, GHB, and heroin. Other items include attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime -- both in and out of school.

survey data

(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 codebook.

Methodology

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.

All archived data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. The archive 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, the archive 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.

Access and Availability

Detailed file-level information (such as record length, case count, and variable count) is listed in the file manifest.
