Monitoring the Future: A Continuing Study of American Youth (12th-Grade Survey), 2009 (ICPSR 28401) RSS

Alternate Title:  MTF 2009 (12th Grade)

Principal Investigator(s):

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, smokeless tobacco, alcohol, marijuana, hashish, prescription medications, over-the-counter medications, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), Quaaludes (methaqualone), barbiturates (tranquilizers), cocaine, crack cocaine, GHB (gamma hydroxy butyrate), ecstasy, methamphetamine, and heroin. Other topics 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).

Scope of Study

Subject Terms:   alcohol, attitudes, crime, demographic characteristics, drug education, drug use, educational objectives, family background, gender roles, high school students, human behavior, lifestyles, prescription drugs, religious attitudes, self esteem, social change, tobacco use, values, youths

Geographic Coverage:   United States

Time Period:  

  • 2009

Date of Collection:  

  • 2009

Unit of Observation:   individual

Universe:   High school seniors in the contiguous United States.

Data Types:   survey data

Data Collection Notes:

Conducted by the University of Michigan, Institute for Social Research, Survey Research Center.

Prior to 2005, the variable asking about race only had categories for Black and White. In 2005, a change was made to include a third category for Hispanic. This new format was implemented on all six forms. This change has continued in 2009. Each form for 2009 allows for Black, White, and Hispanic on the race question.

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.

Frequency and percentage distributions displayed in the 2009 codebooks are unweighted, rather than weighted by variable V5 as they had been in previous years. This change was made to simplify both the production of the codebooks and their interpretation by the analyst.

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 using a probability based on their 2000 Census household count. In schools with more than 350 seniors, a sample of seniors or classes was drawn. In schools with less than 350 seniors, all seniors were asked to participate unless logistical challenges required a sample be taken. 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 6 subsamples consisting of an average of 2,378 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:   on-site questionnaire

Response Rates:   The overall student response rate for 2009 was 82 percent.

Extent of Processing:  ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR 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, ICPSR performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Standardized missing values.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.
