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. 2009 2009 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. In schools with more than 350 students in the grade, a sample of students or classes was drawn. In schools with less than 350 students in a grade, all students 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). For the 8th-grade survey, schools with less than 20 8th graders were excluded from the sample. For the 10th-grade survey, schools with less than 25 10th graders were excluded. 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. In 2005, two of the questionnaire forms had a new version of the race question. It included Hispanic as one of the categories in addition to Black and White. For 2009, all four forms had this new version for the race variable. 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 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. The student response rates for the 2009 8th- and 10th-grade surveys were 88 percent and 89 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. Disclosure of confidential information may also be punishable under federal law. Therefore, users of data agree:

To use these datasets solely for research or statistical purposes and not for re-identification of specific RESEARCH SUBJECTS.

To make no use of the identity of any RESEARCH SUBJECT discovered inadvertently and to report any such discovery to CBHSQ and SAMHDA ( samhda-support@icpsr.umich.edu )

Citing Data

You agree to reference the recommended bibliographic citation in any of your publications that use SAMHSA data. Authors of publications that use SAMHSA data are required to send citations of their published works to ICPSR for inclusion in a database of related publications (bibliography@icpsr.umich.edu ).

Disclaimer

You acknowledge that SAMHSA and ICPSR will bear no responsibility for your use of the data or for your interpretations or inferences based upon such uses.

Violations

If SAMHSA or ICPSR determines that this terms of use agreement has been violated, then possible sanctions could include:

Report of the violation to the Research Integrity Officer, Institutional Review Board, or Human Subjects Review Committee of the user's institution. A range of sanctions are available to institutions including revocation of tenure and termination.

If the confidentiality of human subjects has been violated, then report of the violation may be made 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.

Report of the violation of federal law to the United States Attorney General for possible prosecution.

Court awarded payments of damages to any individual(s)/organization(s) harmed by the breach of confidential data.

 DefinitionsCBHSQ - Center for Behavioral Health Statistics and QualityICPSR - Inter-university Consortium for Political and Social ResearchPromise of confidentiality - A promise to a respondent or research participant that the information the respondent provides will not be disseminated in identifiable form without the permission of the respondent; that the fact that the respondent participated in the study will not be disclosed; and that disseminated information will include no linkages to the identity of the respondent. Such a promise encompasses traditional notions of both confidentiality and anonymity. In most cases, federal law protects the confidentiality of the respondent's identity as referenced in the Promise of Confidentiality. Under this condition, names and other identifying information regarding respondents would be confidential.Research subject - A person or organization that participates in a research study. A research subject may also be called a respondent. A respondent is generally a survey respondent or informant, experimental or observational subject, focus group participant, or any other person providing information to a study.SAMHDA - Substance Abuse and Mental Health Data ArchiveSAMHSA - Substance Abuse and Mental Health Services Administration
