Students in each grade are randomly assigned to complete one of two questionnaires, each with a different subset of topical questions but containing a set of "core" questions on demographics and drug use. There are about 300 variables across the questionnaires. Drugs covered by this survey include amphetamines (stimulants), barbiturates (tranquilizers), other prescription drugs, tobacco, alcohol, inhalants, steroids, marijuana, hashish, LSD, hallucinogens, cocaine, crack, and injection drugs such as heroin. 1998 1998 United States individual Enrolled 8th- and 10th-grade students in the contiguous United States. 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. Separate samples were drawn for each grade. Of the 80 PSUs, 8 were selected with certainty and 72 were selected with probability proportionate to size based on the size of the 8th- (or 10th-) grade class in each school. In schools with more than 400 8th (or 10th) graders, a random sample of students or classes was drawn. In schools with less than 400 8th (or 10th) graders, all students were asked to participate. Each sampled school was asked to participate for two years, so that each year one-half of the sample is 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 15 8th graders were excluded from the sample. For the 10th-grade survey, schools with less than 25 10th graders were excluded. self-administered questionnaires 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.

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 recodes and/or calculated derived variables.Checked for undocumented or out-of-range codes. 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. The participation rate among schools has been between 66 and 80 percent since the inception of the study. The student response rates for the 1998 8th- and 10th-grade surveys were 88 percent and 87 percent, respectively.

These data are distributed under the following terms of use. By continuing past this point to the data retrieval process, you signify your agreement to comply with the requirements as stated below:

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
