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. 2011 2011 United States individual Enrolled 8th- and 10th-grade students in the contiguous United States. survey data 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. on-site questionnaire 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.

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. 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. The student response rates for the 2011 8th- and 10th-grade surveys were 91 percent and 86 percent, respectively.

Privacy of RESEARCH SUBJECTS

Any intentional identification of a RESEARCH SUBJECT (whether an individual or an organization) or unauthorized disclosure of his or her confidential information violates the PROMISE OF CONFIDENTIALITY given to the providers of the information. Therefore, users of data agree:

To use these datasets solely for research or statistical purposes and not for investigation of specific RESEARCH SUBJECTS, except when identification is authorized in writing by ICPSR (netmail@icpsr.umich.edu )

To make no use of the identity of any RESEARCH SUBJECT discovered inadvertently, and to advise ICPSR of any such discovery (netmail@icpsr.umich.edu )

 Redistribution of Data

You agree not to redistribute data or other materials without the written agreement of ICPSR, unless:

You serve as the OFFICIAL or DESIGNATED REPRESENTATIVE at an ICPSR MEMBER INSTITUTION and are assisting AUTHORIZED USERS with obtaining data, or

You are collaborating with other AUTHORIZED USERS to analyze the data for research or instructional purposes.

When sharing data or other materials in these approved ways, you must include all accompanying files with the data, including terms of use. More information on permission to redistribute data can be found on the ICPSR Web site.

Citing Data

You agree to reference the recommended bibliographic citation in any publication that employs resources provided by ICPSR.

If the confidentiality of human subjects has been violated, the case may be reported to the Federal Office for Human Research Protections. This may result in an investigation of the user's institution, which can result in institution-wide sanctions including the suspension of all research grants.

A court may award the payment of damages to any individual(s)/organization(s) harmed by the breach of the agreement.
