title: Monitoring the Future: A Continuing Study of American Youth (12th-Grade Survey), 2005
title: Version 3

description: 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).
description: 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.
description: Response Rates: The overall student response rate for 2005 was 82
percent.
description: 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.

description: self-enumerated questionnaireFor 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.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.Variables omitted from the
Western region questionnaires are noted in each codebook.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.MTF does not release detailed geography codes in its public use files because of the disclosure risk it would cause. The MTF sample is drawn to generate representative samples of the four Census Bureau regions of the country (Northeast, Midwest, South, and West), but it does not generate representative samples of smaller geographic areas such as states, counties, or cities. For additional information about data that is withheld from the public use files please contact MTF directly at mtfinformation@umich.edu.
