Scope of Study

Summary:This survey of 12th-grade students is part of a 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 (methaqualone), barbiturates (tranquilizers), cocaine, crack cocaine, GHB (gamma hydroxy butyrate), ecstasy, methamphetamine, 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).

Data Collection Notes:(1) For 2005, half of the questionnaire forms have a new version of the race question. Previously, the racial categories were Black and White. The new version includes Black, White, and Hispanic. (2) 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. (3) Variables omitted from the Western region questionnaires are noted in each codebook. (4) A user guide is provided with the study documentation. It contains a year-to-year cross-time question index for the MTF 12th-grade surveys, which is sorted by subject area, item reference number, and questionnaire form.
 

Methodology

Sample:A 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 72 PSUs, 8 were selected with certainty, 10 were selected with a probability of .50, and the remainder were selected with a probability proportionate to the size of the senior class. In schools with more than 350 seniors, a random sample of seniors or classes was drawn. In schools with less than 350 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 would be 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 2,300 respondents. 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.
 
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-enumerated questionnaire
 
Response Rates:The overall student response rate for 2005 was 82 percent.

Version History:The last update of this study occurred on 2007-07-18.
 
  2007-07-18 - The Core Codebook was updated to include an index of core drug variables sorted by substance category and form number. It will serve as a table of contents in the frequencies section of the codebook. Also the Base Year Question Index: 1976-2005 was updated to include a few missing question numbers previously omitted.
 
  2007-05-17 - The principal investigator supplied new data to correct one variable (V108) for Part 1: Core Data and to correct five variables (V1108, V1243, V1824, V1825, and V1826) for Part 2: Form 1 Data. Also updated the SAS setup and SAS supplemental syntax files for all seven parts to remove duplicate values embedded in the value labels.
