  • Abstract

    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), sedatives/barbiturates, tranquilizers, cocaine, crack cocaine, GHB (gamma hydroxybutyrate), 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).
  • Methods

    A total of 14,502 12th grade students completed a survey in 2018. The number of students completing each form were: Core Data: 14,502; Form 1 Data: 2,437; Form 2 Data: 2,402; Form 3 Data: 2,416; Form 4 Data: 2,407; Form 5 Data: 2,416; Form 6 Data: 2,424;
  • Methods

    There are about 1,400 variables across the questionnaires. On average, each form consisted of 364 questions. Some questions were repeated on multiple forms and some were asked on all six forms. All of the survey questions are categorical in nature. The majority of questions fall into one of seven types of response options. Yes / No; Marked / Not Marked; Agree / Disagree scale (5 point); Disapproval scale (3 point); Risk scale (4 point); Frequency of days (6 ponit); Frequency of use (7 point); The Core Data file is a compilation of variables from the six questionnaire forms. Variables contained in the Core data file may not appear in all six forms. ICPSR created the final 30 variables of the Core data file to aid in analysis and utility.
  • Methods

    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: Standardized missing values.; Created online analysis version with question text.; Performed recodes and/or calculated derived variables.; Checked for undocumented or out-of-range codes..
  • Methods

    Response Rates: The overall student response rate for 2018 was 81 percent.

Sampled Universe
High school seniors in the contiguous United States. Smallest Geographic Unit: Census Region
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 2010 Census household count. Generally speaking, 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 participation rate among schools has been between 66 and 85 percent since the inception of the study. The total sample of 12th graders was divided randomly into 6 subsamples, each to be administered a different form of the questionnaire. "Core" drug and demographic questions were included in all questionnaire forms.
