Monitoring the Future: A Continuing Study of American Youth (8th- and 10th-Grade Surveys), 2011 (ICPSR 33902) RSS

Alternate Title:  MTF 2011 (8th/10th Grade)

Summary:

These surveys of 8th- and 10th-grade students are part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students in each grade are randomly assigned to complete one of four questionnaires, each with a different subset of topical questions but containing a set of "core" questions on demographics and drug use. There are more than 450 variables across the questionnaires. Drugs covered by this survey include amphetamines (stimulants), barbiturates (tranquilizers), other prescription drugs, over-the-counter medications, tobacco, smokeless tobacco, alcohol, inhalants, steroids, marijuana, hashish, LSD, hallucinogens, cocaine, crack, ecstasy, methamphetamine, and injectable drugs such as heroin.

Geographic Coverage:   United States

Time Period:  

  • 2011

Data Collection Notes:

This study was conducted by the Survey Research Center, Institute for Social Research at the University of Michigan.

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.

Variables omitted from the Western region questionnaires are noted in each codebook.

A user guide is provided with the study documentation. It contains two year-to-year cross-time question indices for the MTF 8th- and 10th-grade surveys. The first is sorted by subject area and the second is sorted by question location.

Frequency and percentage distributions displayed in the 2011 codebooks are unweighted.

Methodology

Sample:   A multistage area probability sample design was used 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. Generally speaking, in schools with more than 350 students in the grade, a sample of students or classes was drawn. In schools with fewer than 350 students in a grade, all students were asked to participate unless logistical challenges required a sample be taken. For the 8th-grade survey, schools with fewer than 20 8th graders were generally excluded from the sample. For the 10th-grade survey, schools with fewer than 25 10th graders were excluded, with very few exceptions. 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 participation rate among schools has been between 66 and 80 percent since the inception of the study.

Weight:   Each of the eight 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 student response rates for the 2011 8th- and 10th-grade surveys were 91 percent and 86 percent, respectively.

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.
