Scope of Study

Summary:This is the 25th 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, and heroin. Other items include attitudes toward religion, parental influences, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime -- both in and out of school.

Data Collection Notes:(1) 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. (2) Variables omitted from the Western region questionnaires are noted in each codebook. (3) Users are advised that there are seven parts to the collection: one containing the "key" or core questions for all six questionnaires and a separate part for each of the six different questionnaire forms. The core file consists of all respondents for all six questionnaires, however, only those variables that appear on all six questionnaires and demographic variables are found in this file. The core file consists primarily of drug use data and demographic variables. (4) The collection is documented by machine-readable codebooks with a separate codebook for each part. Users are further advised to consult the appropriate MONITORING THE FUTURE: QUESTIONNAIRE RESPONSES FROM THE NATION'S HIGH SCHOOL SENIORS annual volume, available from the Monitoring the Future staff, for more information about the collection.
 

Methodology

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. 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 1999 was 83 percent.

Version History:The last update of this study occurred on 2007-09-18.
 
  2007-09-18 - The SPSS setup file for Part 5, Form 4, has been updated in order to correct the value label for V49.
 
  2006-05-15 - Minor edits were made to the metadata and documentation.
 
  2005-11-04 - On 2005-03-14 new files were added to one or more datasets. These files included additional setup files as well as one or more of the following: SAS program, SAS transport, SPSS portable, and Stata system files. The metadata record was revised 2005-11-04 to reflect these additions.
 
  2003-02-06 - The data for two variables in Part 2: Form 1 Data (V1264 and V1813) were replaced per the data producer's request. These changes did not modify the logical record length nor column locations.
